MELLOY, Circuit Judge.

      Kimberly Anne Nowling applied for disability benefits under Title II of the
Social Security Act (the "Act"), 42 U.S.C. § 401, et seq., and supplemental security
income benefits under Title XVI of the Act, 42 U.S.C. § 1381, et seq. An ALJ denied
her application, and the Commissioner declined further review. Nowling
unsuccessfully challenged her denial of benefits in the district court. We remand to
the agency for further proceedings.
                                           I.

      Nowling suffers from conversion disorder manifesting itself as somatoform,
non-epileptic "pseudo-seizures." In addition, she is obese and suffers from migraine
headaches, mood disorder, anxiety disorder, and personality disorder.

       Before turning to the details of Nowling's medical and administrative history,
we describe briefly the phenomenon of conversion disorder and the somatoform, non-
epileptic "pseudo-seizures" that form the core of Nowling's medical issues and
alleged disability. Conversion disorder is a phenomenon in which a person actually
and subjectively experiences symptoms without a known underlying medical cause.
Easter v. Bowen, 867 F.2d 1128, 1129 (8th Cir. 1989). It is believed the symptoms,
such as non-epileptic seizures, result from an unconscious, involuntary conversion
of mental stress into a physiological symptom. Id.; see also Miller v. Colvin, No.
12–2293, 2014 WL 641714 at *3 (W.D. Ark. Feb. 19, 2014) ("Pseudoseizures, or
psychogenic non-epileptic seizures . . . are believed to occur as a part of a conversion
disorder in which the patient unconsciously converts emotional dysfunction into
physical symptoms." (citing Ronald P. Lesser and S. Marc Testa, Symptoms That
Mimic Epilepsy Linked to Stress, Poor Coping Skills, http://www.hopkinsmedicine.
org/news/media/releases/symptoms_that_mimic_epilepsy_linked_to_stress_poor_
coping_skills (last accessed January 26, 2016))). In prior opinions, we reviewed
these or similar disorders and noted the difficulty of assessing how such disorders
limit a person's activities. Metz v. Shalala, 49 F.3d 374, 377 (8th Cir. 1995).1 In


      1
        See also, Easter, 867 F.2d at 1129. There, when faced with an applicant
presenting a long list of symptoms and a diagnosis of somatoform or conversion
disorder, we stated:

      While the objective medical data supporting this list of physical ailments
      are of varying degrees of certainty and specificity, the ALJ had before
      him uncontradicted diagnoses . . . that she suffers from a . . . condition

                                          -2-
particular, we noted that a prime feature of conversion disorder may be a disconnect
between the actual severity of symptoms demonstrated by clinical evidence and the
way the applicant subjectively perceives the symptoms. See, e.g., Easter, 867 F.2d
at 1130 ("[H]er primary disorder, as clinically diagnosed, causes her to exaggerate her
physical problems in her mind beyond what the medical data indicate."). That is not
to say this exaggerated experience of symptoms amounts to malingering. Id. Rather,
the applicant actually believes herself to be experiencing symptoms at a greater level
of severity than clinical evidence can support.

       Given this disconnect, an obvious difficulty arises when it becomes necessary
to make credibility assessments in cases involving somatoform phenomena.
Subjective perceptions of somatoform effects may, in fact, be debilitating even when
clinical or diagnostic medical evidence does not fully support the claimed symptoms.
It nevertheless remains necessary to make credibility assessments in these settings,
and "[i]n cases involving somatoform disorder . . . an ALJ is not free to reject
subjective experiences without an express finding that the claimant's testimony is not
credible." Metz, 49 F.3d at 377. Where such a finding has been made, "[w]e will not
disturb the decision of an ALJ who considers, but for good cause expressly discredits,
a claimant's complaints . . . even in cases involving somatoform disorder." Gowell
v. Apfel, 242 F.3d 793, 796 (8th Cir. 2001).




      known as somatoform or conversion disorder. This mental disturbance
      causes her to believe that her physical ailments are more serious than the
      clinical data would suggest. As described in the Diagnostic and
      Statistical Manual of Mental Disorders (Third Edition) at pages 244 and
      247, conversion disorder is not under a patient's voluntary control. In
      other words, Mrs. Easter experiences her physical problems as worse
      than they may in fact be, and is unable to control this response.


                                         -3-
       Given the difficulty in this area, if an ALJ expressly accepts that a claimant
suffers from a somatoform disorder, but also finds the claimant at least partially non-
credible, the ALJ ideally should set forth the credibility determination with sufficient
detail to expressly inform the reviewing court as to the factual details of the
petitioner's limitations as accepted or believed by the ALJ. And in this type of case,
even more so than in other cases, corroborating testimony from actual witnesses such
as family members or former employers regarding the nature of the symptoms may
hold particular value for a fact finder.

       With this background in mind, we turn to the record. Nowling began
experiencing seizure-like episodes prior to 2007. She worked as a nurses aid and
bathing assistant. Over time, her employer cut her hours and duties because it was
not safe for her to be alone with patients or lift or bath patients given her potential for
seizure-like episodes. In December 2007, following an episode of seizure-like
symptoms, her employer asked her to see a neurologist and instructed her not to
return to work until she did. Nowling visited neurologists, who identified no
neurological cause for her symptoms and identified no signs of brain activity
suggestive of actual epilepsy. She returned to work on a reduced basis. Eventually,
in August 2008, she quit her job due to an inability to work alone with patients.

       On March 6, 2009, she applied for Title II and Title XVI benefits. She
originally alleged an onset date of March 6, 2009. Her applications were denied, and
at a hearing before an ALJ on March 16, 2011, she amended her alleged onset date
to February 28, 2008. She did not allege her condition materially worsened in late
February 2008. Rather, February 28, 2008, is a date when she asked for and received
a doctor's note recommending that she restrict her working hours to 7 ½ hours per
day, three days per week.2


      2
       The record is clear that Nowling suggested these particular restrictions to her
doctor. The record also is clear that her employer reduced her duties due to patient

                                           -4-
       Medical evidence from treating physicians was largely consistent between 2007
and 2011. Nowling saw neurologist Mignon Makos in 2007. Dr. Makos found no
evidence of epileptic seizures. Nowling experienced a seizure-like episode during her
exam, and Dr. Makos indicated that Nowling was able to sit but a nurse needed to
hold her head and neck. Dr. Makos also indicated that Nowling's eyes appeared to
react voluntarily to stimulus during the pseudo-seizure and that she appeared to recoil
voluntarily in response to discomfort. She recovered quickly after her seizure and
experienced little physical change other than temporarily slightly elevated blood
pressure. Dr. Makos diagnosed her with conversion disorder/somatoform pseudo-
seizures and took her off seizure medication. Nowling reported to Dr. Makos that she
frequently suffered migraine headaches and that her headaches often preceded her
more severe seizures. Dr. Makos placed her on medication to treat her headaches in
an effort to control the pseudo-seizures.

      Nowling received treatment from general practitioner Eduardo Fernandez,
M.D., from October 2007 through July 2010; psychiatrist Jose Menendez, M.D., from
August 2006 through January 2011 (at least 29 office visits); and licensed social
worker Nancy Miller from April 2009 through January 2011 (at least 38 visits or
therapy sessions). These care providers consistently diagnosed and treated Nowling
with conversion disorder manifesting as non-epileptic/pseudo-seizures. During
treatment, Miller consistently described Nowling with a GAF score of 45 or 50;
and Dr. Menendez described a GAF score of 50.3 No care provider diagnosed her


safety concerns. It is unclear whether Nowling herself or her employer originally
formulated these restrictions as presented for approval from her physician.
      3
        In Pate-Fires v. Astrue, 564 F.3d 935, 937–38 n.1–3 (8th Cir. 2009), we
explained:

      The GAF is a numeric scale ranging from zero to one hundred used to
      rate social, occupational and psychological functioning "on a
      hypothetical continuum of mental health-illness." Diagnostic and

                                         -5-
with epileptic seizures nor identified a physically identifiable cause for her seizures.
No care provider assigned a GAF score greater than 50 other than Dr. Menendez who,
in a "medical source statement form" completed on November 30, 2010, listed a GAF
score of 56 as both her current level of functioning and as the highest level of
functioning in the preceding year. In the same form, Dr. Menendez described
Nowling's impairments as severe, noted that she was not a malingerer, and stated that
her impairments would cause her to be absent from work "more than four days per
month." Even though he described her impairments in this fashion, the GAF score
of 56 generally reflects only a moderate level of impairments.

       Treatment notes from all caregivers reflect that Nowling described the
frequency of her seizures as waxing and waning over the years. She described them
as occurring as often as two or three per week and as infrequently as two to three per
month. Nowling reported that headaches of varying intensity, including migraine
headaches, often preceded her seizures. She received medicine for anxiety and
personality disorder as well as medicine to control headaches. Over the course of her
treatment her physicians frequently changed her drugs and dosages in an attempt to
better control her headaches and seizures. Although many treatment notes indicate

      Statistical Manual of Mental Disorders, 32 (4th ed. Am. Psychiatric
      Ass'n 1994) (DSM–IV). . . . A GAF of 41 to 50 indicates the individual
      has "[s]erious symptoms . . . or any serious impairment in social,
      occupational, or school functioning. . . ." DSM–IV at 32. A GAF of 51
      to 60 indicates the individual has "[m]oderate symptoms . . . or moderate
      difficulty in social, occupational, or school functioning. . ." DSM–IV
      at 32.

In recent years, the agency has recognized, and we have noted, that GAF scores have
limited importance. Jones v. Astrue, 619 F.3d 963, 973–74 (8th Cir. 2010)
("Moreover, the Commissioner has declined to endorse the [GAF] score for use in the
Social Security and [Supplemental Security Income] disability programs and has
indicated that [GAF] scores have no direct correlation to the severity requirements of
the mental disorders listings." (internal citations omitted)).

                                          -6-
mild improvement, read as a whole they show her symptoms waxed and waned with
some short term improvement but without substantial long-term worsening or
improvement during the 2008 to 2011 time frame.

       In treatment notes, Dr. Fernandez, Dr. Menendez, and Ms. Miller often recited
Nowling's reports of her symptoms as well as her reports of how she had been
spending her time. These reports were largely consistent with a later description of
daily activities Nowling provided during her ALJ hearing. She did not drive, other
than a one-mile route to her brother's home, for fear of having an episode and causing
an accident. She did not shop or generally go out in public alone. Her father or her
sister-in-law generally drove her when needed. She could do yard work "at her own
pace," did her own laundry, and cooked for herself and her father twice per week.
One day per week, her father would drive her to her sister's home in the morning
where she would help her sister's children prepare for school and get on a bus. She
typically would watch television for one to one and a half hours per day. She liked
to read and work on the computer, but she could only work on the computer for about
fifteen to twenty minutes or read for about half an hour before headaches made her
stop.

      In addition, Nowling described several vacations and family events she
attended: at least one instance of camping; an event where she helped to host a large
group of family; monthly trips to see her brother in Nebraska; attending and helping
with children's sporting events; and vacationing once in western Nebraska and once
in North Carolina. Following the trip to western Nebraska, Nowling reported to Dr.
Menendez that she felt relaxed and had not suffered a seizure-like episode at all
during her trip. Dr. Menendez's notes from that office visit indicate that Nowling
"did not appear to have any symptoms in the absence of stress."

      To her doctors, to Ms. Miller, and to the ALJ, she described her seizure-like
episodes as varying in intensity and effect. Some episodes involved complete loss of

                                         -7-
consciousness, some involved tremors and shaking, and still others involved an
inability to form words and articulate thoughts. The durations varied from five
minutes or less to more than twenty minutes, and recovery times following episodes
varied from minutes to a whole day. In her hearing testimony, Nowling described her
seizures as occurring "in spurts" where she might have two or three in the same day
but then go a month without having one. No treating physician suggested any belief
or suspicion that Nowling was malingering or exaggerating her symptoms.

      In the medical source statement form prepared on November 30, 2010, Dr.
Menendez described Nowling as seriously limited or unable to meet competitive
standards in several respects, including an inability to "[m]aintain regular attendance
and be punctual within customary, usually strict tolerances," "[c]omplete a normal
workday and workweek without interruptions from psychologically based
symptoms," "[r]espond appropriately to changes in a routine work setting," or "[d]eal
with stress of semiskilled and skilled work."

       Consulting psychologist John Keough, MA, met with Nowling and conducted
a psychological exam in May 2009. He concluded Nowling's general life activities
and presentation during her examination did not demonstrate severe limitations. In
particular, Mr. Keough recited several of Nowling's self-described activities,
discussed her mannerisms and ability to respond to his questioning, and concluded
she could function in a low stress/low demand workplace.

      In addition, consulting psychologist Margaret Sullivan, PhD, reviewed
Nowling's records and found only mild to moderate limitations, reaching conclusions
consistent with those of Mr. Keough.

       Nowling's sister-in-law, Dawn Nowling, testified extensively about her
interactions with Nowling and her observations of Nowling's seizures. Dawn
Nowling spent at least some time with Nowling on a daily basis, some days spending

                                         -8-
most of the day with her. Dawn Nowling reported witnessing approximately forty
seizure-like events since 2010.4 She described most events as lasting five to ten
minutes with relatively short recovery times, but approximately twenty-five percent
of the events lasted for fifteen to twenty minutes or longer and required greater
recovery times. Dawn Nowling described Nowling's activities in a manner consistent
with Nowling's description: Nowling refused to drive herself or appear in public
alone but managed self-care, housekeeping, and yard care on her own pace and
participated in family events and other events when accompanied. Dawn Nowling
described herself or other family members moving Nowling to a chair or laying her
down when seizure-like symptoms would arise. She also described the more mild
episodes as akin to someone who has had a stroke and cannot formulate words or
focus. Finally, she described the seizure-like episodes as having become a fairly
routine occurrence that family members were accustomed to dealing with because
they had been happening for a long time and physicians could not determine physical
cause or offer effective treatment.

      In a written opinion issued after the hearing, the ALJ applied the five-step
sequential analysis of 20 C.F.R. § 404.1520 and § 416.920. The ALJ found Nowling
non-credible but did not wholly reject her claimed limitations or the existence of the
pseudo-seizures.5 Rather, the ALJ found that some level of limitations and medically


      4
        The hearing took place on March 16, 2011. When asked how many seizures
she had witnessed "since 2010," Dawn Nowling responded "probably two or three a
month." The ALJ then noted that this number would be "about 40-some." Given this
dialogue, it appears the ALJ and Dawn Nowling understood themselves to be
discussing the frequency of seizure-like episodes in the approximately fourteen to
fifteen months preceding the hearing.
      5
           The entirety of the ALJ's commentary on Nowling's credibility was as
follows:



                                         -9-
supported symptoms existed but at a lesser severity than that claimed by Nowling.
The ALJ concluded the medical evidence could be expected to cause Nowling's
general symptoms. The ALJ, however, did not address the primary feature of
conversion disorder and somatoform symptoms, namely, the extent to which Nowling
actually perceived symptoms and the extent to which conversion disorder rather than
a lack of credibility might explain an absence of objective medical support for her
symptoms.

       In reaching his conclusions, the ALJ determined Dr. Menendez's opinion (the
medical source statement) was entitled to "little weight" because the opinion was
internally inconsistent in that it listed a GAF score of 56 but described Nowling's
impairments as severe. The ALJ noted that Dr. Menendez's opinion was inconsistent
with the opinions of the consulting psychologists and "not well supported." The ALJ
also stated Dr. Menendez's opinion was inconsistent with the balance of Dr.
Menendez's own treatment notes. The ALJ, however, relied heavily upon: (1) the
comment from Dr. Menendez that Nowling's symptoms did not appear to arise in the
absence of stress, and (2) comments in Dr. Menendez's treatment notes indicating
Nowling showed "improvement." The ALJ gave "greatest weight" to the opinion of
Mr. Keough, the psychologist who examined Nowling once. The ALJ also gave
"great weight" to the opinion of Margaret Sullivan, PhD, the non-examining
psychologist who reviewed Nowling's records. Finally, the ALJ commented upon




      After careful consideration of the evidence, the undersigned finds that
      the claimant's medically determinable impairments could reasonably be
      expected to cause the alleged symptoms; however, the claimant's
      statements concerning the intensity, persistence and limiting effects of
      these symptoms are not credible to the extent they are inconsistent with
      the . . . residual functional capacity assessment.

Nancy Miller only to indicate that Nancy Miller repeated the GAF score of 50, and
the ALJ did not mention the testimony from Dawn Nowling.6

       The ALJ determined, pursuant to 20 C.F.R. §§ 404.1520(a)(4) and
416.920(a)(4) that: (i) Nowling had not engaged in substantial gainful activity since
the amended onset date; (ii) she suffered from the following impairments that, at least
in combination, were severe: conversion disorder with pseudo-seizures, headaches,
mild obesity, mood disorder, anxiety disorder (not otherwise specified), and
personality disorder (not otherwise specified), but medical evidence did not show
them to be so severe as to preclude work for 12 months; (iii) she did not have a listed
impairment or a combination of impairments that met or medically equaled a listed
impairment; (iv) she could not perform her past relevant work; but (v) she retained
the residual functional capacity to:

      perform light work as defined in 20 C.F.R. 404.1567(b) and 416.967(b)
      except [she] must have limited contact with the public and she can only
      perform simple, repetitive, routine tasks no higher than [tasks requiring
      between 1 and 3 months to learn] and only in a stress-free work
      environment; she cannot work at unprotected heights or work around
      dangerous or moving machinery, she can occasionally bend but never
      crawl, kneel, crouch, or squat; she cannot be exposed to extreme hot or




      6
          Regarding Nancy Miller, the ALJ stated in his written opinion at 17:

      That GAF number is then repeated in the treatment notes of Nancy
      Miller, a licensed clinical social worker, over the course of 2 years of
      treatment. This would indicate that despite 2 years of medication and
      therapy, the claimant did not improve at all, which is highly inconsistent
      with Dr. Menendez's notes, his opinion as to the claimant's GAF, and
      also with Ms. Miller's notes, who herself noted "improvement"
      repeatedly.

                                         -11-
      cold and she cannot drive motorized vehicles as part of her job
      responsibilities.

       At the hearing, the ALJ presented this residual functional capacity to a
qualified vocational expert in three separate hypothetical scenarios. In a first
scenario, the ALJ described Nowling's restrictions exactly as quoted. With these
restrictions, the vocational expert opined that Nowling could work as a price marker,
a router, or a mail folding machine operator—DOT listed positions deemed consistent
with these limitations and available in substantial numbers in the state and national
economies. 20 C.F.R. §§ 404.1520(e), (g); id. §§ 416.920(e), (g).

        In a second scenario, the ALJ again asked the vocational expert to consider the
limits described in the residual functional capacity assessment but added seizures
with subsequent recovery periods that would make Nowling unable to work for half-
day periods on an unpredictable basis, with such periods arising once per week. And
in a third scenario, the ALJ described a similar, periodic inability to perform any work
but with the inability to work caused by headaches rather than pseudo-seizures. As
to both of the latter scenarios (her baseline restrictions as quoted above coupled with
a periodic and unpredictable wholesale inability to work due to either seizures or
headaches), the vocational expert opined that the resulting absenteeism would be
unacceptable to any employer such that there were no jobs Nowling could perform
if she had those limitations. The ALJ concluded Nowling was not disabled, accepting
the vocational expert's response to the first hypothetical situation and finding
Nowling could perform the cited jobs. The Commissioner denied further review, and
the ALJ's opinion is the final administrative order. The district court affirmed.

                                          II.

      We review de novo the district court's judgment affirming the ALJ's denial of
benefits. Grable v. Colvin, 770 F.3d 1196, 1201 (8th Cir. 2014). We owe substantial


                                         -12-
deference to the agency, however, and will "affirm if the ALJ made no legal error and
the ALJ's decision is supported by substantial evidence in the record as a whole." Id.
"Substantial evidence is less than a preponderance of the evidence, but is 'such
relevant evidence as a reasonable mind would find adequate to support the
commissioner's conclusion.'" Id. (quoting Davis v. Apfel, 239 F.3d 962, 966 (8th Cir.
2001)). "In determining whether existing evidence is substantial, this court looks at
both evidence that supports and evidence that detracts from the Commissioner's
decision." Bergmann v. Apfel, 207 F.3d 1065, 1068 (8th Cir. 2000). "We may not
reverse simply because we would have decided differently or because substantial
evidence supports a contrary outcome." Grable, 770 F.3d at 1201.

       Several matters, as determined by the ALJ, are undisputed at this time:
Nowling suffers from conversion disorder manifesting itself as somatoform, non-
epileptic "pseudo-seizures." In addition, she is obese and suffers from migraine
headaches, mood disorder, anxiety disorder, and personality disorder. She cannot
continue her past work, and she is subject to physical and work-environment
limitations due to her conditions.

       Notwithstanding these determinations, several matters remain unclear. The
ALJ stated Nowling was non-credible in part, finding she exaggerated her symptoms.
But it is unclear whether this determination was a finding of malingering or an
exaggeration related to the nature of conversion disorder. Further, the ALJ neither
explained how extensive he determined Nowling's symptoms to be nor addressed the
effect of her conversion disorder upon her perception of her own symptoms. It
therefore remains unclear what symptoms the ALJ actually believed Nowling
experiences and what, if any, effect her conversion disorder has upon her ability to
work.

       In the context of this uncertainty, Nowling argues the ALJ committed legal
error in three respects resulting in a conclusion not supported by substantial evidence

                                         -13-
on the record as a whole. First, she argues the ALJ failed to consider testimony from
her sister-in-law, Dawn Nowling, who witnessed Nowling's non-epileptic seizures.
Second, she argues the ALJ improperly discounted Dr. Menendez's opinion. Third,
she argues the ALJ improperly discounted Nancy Miller’s opinion. We address these
arguments below and conclude remand is required.

      In particular, we conclude the errors identified by Nowling show the ALJ failed
to consider Mental Impairment Listing 12.07 Somatoform Disorders (including
Conversion Disorder) when assessing Nowling's residual functional capacity. The
ALJ’s opinion asserts that he "considered whether the claimant's pathology and
attending symptoms met or equaled" Listing 12.07. The ALJ, however, did not
consider the listing in relation to Nowling's residual functional capacity in the manner
required by the regulations governing Mental Disorders, Subpt. P, App. 1 § 12.00.

       Section 12.00.D.1. addresses sources of evidence in considering mental
impairments. The ALJ’s conclusory finding that Nowling was not credible did not
take § 12.00.D.1.b. into account. The failure to consider Dawn Nowling's testimony
and limited consideration of Nancy Miller's treatment records was contrary to
§ 1200.D.1.c. The failure to consider the medical evidence "longitudinally" was
contrary to § 12.00.D.2., leading to unwarranted emphasis on the one-time evaluation
of Keogh and an evaluation of Dr. Menendez based on the November 2010 medical
source statement rather than Dr. Menendez's entire course of treatment. Further, as
noted above, supra at n. 3, the excessive (almost exclusive) reliance on the GAF
scores was an improper basis upon which to discount the substantial longitudinal
treatment records of Dr. Menendez. Finally, the ALJ failed to consider whether
Nowling's chronic impairment resulted in a structured life that masked the extent to
which she is impaired from working, see §§ 1200.E. and F.

      We also conclude the ALJ failed to evaluate fully the vocational expert's
testimony. In posing the second and third hypotheticals regarding seizures and

                                         -14-
headaches and recovery times, the ALJ described lesser impairments than Nowling
claimed. The vocational expert nonetheless said both conditions were disabling
because they would cause unscheduled, excessive absenteeism—the exact reason Dr.
Menendez's medical source statement concluded Nowling was disabled. Yet the ALJ
made no finding that Nowling's conversion disorder was of less severity than what
he described in his hypotheticals.

                                 A. Dawn Nowling

       Dawn Nowling is not a medical source, but her testimony reflects on the
severity of Nowling's impairments and is evidence the ALJ is to consider in applying
the five-step sequential analysis. See 20 C.F.R. § 404.1513(d). It is undisputed the
ALJ's opinion failed to address Dawn Nowling's testimony expressly or describe what
weight, if any, the ALJ accorded her testimony. In general such an omission need not
lead our court to reverse an ALJ's otherwise-supported decision. See, e.g., Buckner
v. Astrue, 646 F.3d 549, 560 (8th Cir. 2011) (rejecting an argument that the failure
to address a lay-witness's description of symptoms required remand, stating, "the
ALJ's 'arguable deficiency in opinion-writing technique,' had no bearing on the
outcome of [the] case and does not require remand" (quoting Robinson v. Sullivan,
956 F.2d 836, 841 (8th Cir. 1992))); Wildman v. Astrue 596 F.3d 959 (8th Cir. 2010)
("Although required to develop the record fully and fairly, an ALJ is not required to
discuss every piece of evidence submitted." (quoting Black, 143 F.3d at 386)). When
coupled with other "errors and uncertainties in the opinion," Willcockson v. Astrue,
540 F.3d 878, 880 (8th Cir. 2008), however, we have remanded for reconsideration
and clarification by the agency, id. at 881. And, here the failure to consider Dawn
Nowling's testimony was contrary to the governing regulations. See 20 C.F.R. Pt.
404, Subpt. P, App. 1, § 1200.D.1.c ("If necessary, information should also be
obtained from nonmedical sources, such as family members and others who know
you, to supplement the record of your functioning in order to establish the consistency
of the medical evidence and longitudinality of impairment severity . . . .").

                                         -15-
       Dawn Nowling testified regarding Nowling's daily activities in a manner
consistent with Nowling's testimony and statements to her physicians. In particular,
Dawn Nowling stated that Nowling did not shop or otherwise go out publicly by
herself for fear of having a seizure-like episode when unaccompanied. The ALJ,
however, recited his understanding of Nowling's activities as including shopping by
herself.7 The failure to consider Dawn Nowling's testimony and the misstatement of
the record in this regard demonstrates a failure to properly analyze the effects of a
structured setting as required by the regulations. Id. § 1200.F (describing the
potentially mitigating effect of life in structured setting, whether an institution or a
home, upon symptoms).8 Simply put, the nature of the medical condition and the
nature of the life activities, including such considerations as independence, should be
considered against the backdrop of whether such activities actually speak to


      7
         This finding appears to enjoy no support in the record as the evidence we
identified indicates Nowling and Dawn Nowling both stated Nowling restricted her
public activities in this regard to situations where family members accompanied her.
      8
          20 C.F.R. Pt. 404, Subpt. P, App. 1 § 1200.F provides:

      Particularly in cases involving chronic mental disorders, overt
      symptomatology may be controlled or attenuated by psychosocial factors
      such as placement in a hospital, halfway house, board and care facility,
      or other environment that provides similar structure. Highly structured
      and supportive settings may also be found in your home. Such settings
      may greatly reduce the mental demands placed on you. With lowered
      mental demands, overt symptoms and signs of the underlying mental
      disorder may be minimized. At the same time, however, your ability to
      function outside of such a structured or supportive setting may not have
      changed. If your symptomatology is controlled or attenuated by
      psychosocial factors, we must consider your ability to function outside
      of such highly structured settings.

claimant's ability to hold a job. Participation in activities with family or activities at
home and at "your own pace" may not reflect an ability to perform at work. And, "a
claimant need not be bedridden to qualify for disability benefits." Hutsell v.
Massanari, 259 F.3d 707, 713 (8th Cir. 2001).

       Citing Buckner, the agency argues any error in failing to discuss Dawn
Nowling's testimony does not require remand because the same evidence that
discredits Nowling's testimony also discredits Dawn Nowling's testimony. Buckner,
646 F.3d at 559–60 (denying remand where it was not possible to determine whether
the ALJ had considered lay testimony but where it was clear the same evidence that
discredited the claimant's testimony would also discredit the lay witness's testimony).
The agency's argument in this regard misses the mark. First, it is unclear what exactly
the ALJ found not credible about Nowling, other than the conclusion that her
symptoms were some unarticulated degree of severity less than she described them
to be. In this setting, even without taking into account the peculiarities of a
somatoform disorder, Dawn Nowling's testimony is neither redundant with Nowling's
testimony, nor is it discredited by the same evidence that purportedly discredits
Nowling's testimony. Rather, Dawn Nowling's testimony serves as a third-party's
observation of the symptoms the ALJ appears to have rejected as non-credible
subjective complaints. See Willcockson, 540 F.3d at 881 ("[W]e question whether
witness statements corroborating a claimant's subjective complaints can logically be
treated as cumulative by assuming that they would have been rejected for the same
reasons that the claimant statements were rejected, where the agency itself says that
because subjective complaints are hard to document, it will 'carefully consider'
evidence from other persons addressing the extent of the claimant's pain and how it
affects his or her ability to function." (quoting 20 C.F.R. § 404.1529(c)(3))).

        Further, the ALJ's opinion and the agency's argument on appeal ignore entirely
the general nature of somatoform disorders. As in Easter, "the ALJ's opinion . . .
cites . . . somatoform disorder [but] does not adequately consider the effects of that

                                          -17-
mental condition." 867 F.2d at 1130. The ALJ found Nowling suffered from
conversion disorder but at no point accorded any consequence to that fact or to the
nuance our court recognized in Easter that somatoform disorders may be disabling
and may result in "a distorted perception of . . . physical ailments." Id. at 1131. In
this situation, and in light of the additional concerns detailed below, we cannot find
the failure to address Dawn Nowling's testimony harmless nor characterize it merely
as an "arguable deficiency in opinion-writing technique." Robinson, 956 F.2d at 841

                         B. Dr. Menendez & Nancy Miller

       "A treating physician's opinion 'should be granted controlling weight if it is
well-supported by medically acceptable clinical and laboratory diagnostic techniques
and is not inconsistent with the other substantial evidence in the record.'" Miller v.
Colvin, 784 F.3d 472, 477 (8th Cir. 2015) (quoting Cunningham v. Apfel, 222 F.3d
496, 502 (8th Cir. 2000)). A treating physician's opinion, however, "does not
automatically control or obviate the need to evaluate the record as a whole."
Id. (quoting Hogan v. Apfel, 239 F.3d 958, 961 (8th Cir. 2001)). Rather, "an ALJ
may discount or even disregard the opinion of a treating physician where other
medical assessments are supported by better or more thorough medical evidence or
where a treating physician renders inconsistent opinions that undermine the
credibility of such opinions." Id. (quoting Wildman, 596 F.3d at 964 (further citation
omitted)).

      The ALJ discounted Dr. Menendez's opinion because the GAF score of 56 in
the medical source statement was inconsistent with the other experts' opinions and
with Dr. Menendez's other opinions and statements. As stated above, supra at n. 3,
however, GAF scores are of little value. As such, it is error to disregard such
substantial longitudinal treatment based merely upon one of several reported GAF
scores.



                                        -18-
       Further, we note the ALJ improperly accorded great weight to statements in Dr.
Menendez's treatment notes indicating that Nowling demonstrated "improvement"
without acknowledging that Nowling's symptoms waxed and waned throughout the
substantial period of treatment, without acknowledging the unpredictable and
sporadic nature of Nowling's symptoms, and without assessing the effect of her
structured living environment. See Hutsell, 259 F.3d at 712 (stating that an ALJ may
have "relied too heavily on indications in the medical record that [the claimant] was
'doing well,' because doing well for the purposes of a treatment program has no
necessary relation to a claimant's ability to work or to her work-related functional
capacity"); see also 20 C.F.R. Pt. 404, Subpt. P, App. 1, § 1200.F ("If your
symptomatology is controlled or attenuated by psychosocial factors, we must consider
your ability to function outside your highly structured settings." (emphasis added)).
The ALJ's superficial references to the GAF score and Nowling's "improvement" fail
to satisfy the regulations' "require[ment] that the ALJ 'always give good reasons' for
the weight afforded to a treating physician's evaluation." Reed v. Barnhart, 399 F.3d
917, 921 (8th Cir. 2005) (quoting 20 C.F.R. § 404.1527(d)(2)). Here those reasons
must be articulated with acknowledgment of the nature of the disorder at issue and
with consideration given to Dawn Nowling's corroborating testimony.

       Finally, Nowling argues the ALJ failed to consider the extensive treatment
records from Nancy Miller.           Nancy Miller, the licensed clinical social
worker/therapist who treated Nowling over the course of 38 visits and who
consistently rated Nowling's impairments as severe, is not an "acceptable medical
source," 20 C.F.R. § 404.1513(a), but is an "other medical source," id. § 404.1513(d),
whose opinion the ALJ is to consider when assessing the severity of an impairment
and how it affects the ability to work. See id. § 416.913. Generally, "[i]n
determining what weight to give 'other medical evidence,' the ALJ has more
discretion and is permitted to consider any inconsistencies found within the record."
Raney, 396 F.3d at 1010 (quoting 20 C.F.R. § 416.927(d)(4)). The agency itself,
however, has instructed that the opinion of an "other medical source" generally

                                        -19-
should be considered pursuant to several pertinent factors, including the length of
treatment. See Social Security Ruling (SSR) 06–3p, 71 Fed. Reg. 45,593, 2006 WL
2329939, at *6 (Aug. 9, 2006);9 20 C.F.R. Pt. 404, Subpt. P, App. 1 §1200.C. ("Other
professional health care providers . . . can normally provide valuable functional
information, which should be obtained when available and needed."). In light of the
extensive treatment history between Nancy Miller and Nowling, and the consistency
between Nancy Miller and Dr. Menendez's treatment records, it was error to disregard
Nancy Miller's testimony based solely on the reference to GAF scores. See supra n.
3 & 6.

                                    III. Conclusion

     For the reasons stated, we remand with instructions to the district court to
remand this case to the agency for further consideration.

          The Social Security Ruling states:

      Although there is a distinction between what an adjudicator must
      consider and what the adjudicator must explain in the disability
      determination or decision, the adjudicator generally should explain the
      weight given to opinions from these "other sources," or otherwise ensure
      that the discussion of the evidence in the determination or decision
      allows a claimant or subsequent reviewer to follow the adjudicator's
      reasoning, when such opinions may have an effect on the outcome of the
      case.
