            Appeal from the United States District Court
                  For the Western District of Texas
                              (94-CV-608)
          _______________________________________________
                            April 17, 1996

Before HIGGINBOTHAM, DUHÉ, and EMILIO M. GARZA, Circuit Judges.

PER CURIAM:*

     Plaintiff Douglas R. Brock appeals the district court's order

affirming the decision of the Commissioner of Social Security

("Commissioner") denying Brock's claim for supplemental security

income ("SSI") benefits.      We affirm.

                                     I

     Brock applied for SSI benefits, alleging a disability which

prevented gainful employment.       After an administrative hearing, at


     *
            Pursuant to Local Rule 47.5, the Court has determined that this
opinion should not be published and is not precedent except under the limited
circumstances set forth in Local Rule 47.5.4.
which Brock represented himself, the administrative law judge

("ALJ") found that Brock was not disabled and denied Brock's claim

for benefits. Brock exhausted his administrative remedies and then

filed a claim in district court.           The district court granted

summary judgment for the Commissioner and affirmed the ALJ's

decision to deny Brock's claim.         Brock filed a timely notice of

appeal.

                                  II

     Brock argues that the district court erred when it granted the

Commissioner's motion for summary judgment.       We review a district

court's grant of summary judgment de novo, applying the same

standard as the district court.    Bodenheimer v. PPG Indus. Inc., 5

F.3d 955, 956 (5th Cir. 1993).    Summary judgment is appropriate in

cases in which there is no genuine issue of material fact and the

movant is entitled to judgment as a matter of law.      FED. R. CIV. P.

56(c).    In applying this standard to the decision of an ALJ

regarding SSI benefits, our review is limited to two inquiries: (1)

whether there is substantial evidence in the record to support the

decision; and (2) whether the decision comports with relevant legal

standards.   Carrier v. Sullivan, 944 F.2d 243, 245 (5th Cir. 1991).

     The ALJ owes a duty to a claimant to develop the record fully

and fairly to ensure that his decision is an informed decision

based on sufficient facts.    Kane v. Heckler, 731 F.2d 1216, 1219

(5th Cir. 1984).   When a claimant is not represented by counsel,

the ALJ owes a heightened duty to "scrupulously and conscientiously

probe into, inquire of, and explore for all relevant facts."       Id.


                                  -2-
at 1219-20 (citations and internal quotation marks omitted).                        We

will reverse the decision of an ALJ as not supported by substantial

evidence if the claimant shows (1) that the ALJ failed to fulfill

his duty to adequately develop the record, and (2) that the

claimant was prejudiced thereby.               Id. at 1220.

      After his hearing, Brock wrote a letter to the ALJ stating

that he suffered from depression and the effects of past drug

abuse.       Brock contends that the ALJ failed to adequately develop

the     record    by   not    ordering     a    consultative          examination   to

investigate these claims of non-exertional impairment. An ALJ must

order    a     consultative    evaluation       when   such      an    evaluation   is

necessary to enable the ALJ to make the disability determination.

Turner    v.     Califano,    563   F.2d   669,    671    (5th    Cir.    1977).     A

consultative evaluation becomes "necessary" only when the claimant

presents evidence sufficient to raise a suspicion concerning a non-

exertional impairment. Jones v. Bowen, 829 F.2d 524, 526 (5th Cir.

1987).       We have previously held that isolated comments by a

claimant are insufficient, without further support, to raise a

suspicion of non-exertional impairment.                  See Pierre v. Sullivan,

884 F.2d 799, 802-03 (5th Cir. 1989) (holding isolated comments

about claimant's low intelligence insufficient to raise suspicion

that claimant was mentally retarded).              Brock's only references to

depression and drug abuse were made in his post-hearing letter to

the ALJ.        He did not mention non-exertional impairments in his

original request for benefits; he never sought medical treatment

for such impairments; and he did not mention these impairments at


                                         -3-
his hearing.      Therefore, we find that Brock's allegations of non-

exertional impairments were the kind of isolated comments which are

insufficient to raise a suspicion of non-exertional impairment.

Consequently, the ALJ was not required to order a consultative

examination in order to fulfill his duty to adequately develop the

record.

     We must now determine whether, in other respects, the ALJ at

Brock's   hearing    satisfied    his    heightened   duty    to   elicit   all

relevant facts.     In James v. Bowen, 793 F.2d 702, 704-05 (5th Cir.

1986), we held that the ALJ satisfied this heightened duty by

questioning the claimant about his medical condition, asking about

his ability to perform various tasks and daily activities, and

inviting the claimant to include anything else in the record.

Similarly, in     Carrier v. Sullivan, we held that the ALJ satisfied

this heightened duty by questioning the claimant about his medical

condition, asking about the effectiveness of attempted treatments,

and inquiring about how the claimant's daily routine had been

affected.    944 F.2d at 245.      During the hearing at issue in this

case, the ALJ extensively questioned Brock about his education,

training, and past work history; about the circumstances of his

injury;     and   about   his    daily     routine,   pain,    and   physical

limitations.      The ALJ also considered a medical report obtained

from Brock's treating physician and invited Brock to add other

relevant evidence to the record.          Based on the foregoing, we find

that the ALJ satisfied his heightened duty to fully develop the

record.


                                     -4-
      We also find that Brock has failed to show that he was

prejudiced by the ALJ's alleged failure to fully develop the

record.     To establish prejudice, a claimant must show that he

"could and would have adduced evidence that might have altered the

result."    Kane, 731 F.2d at 1220.          Brock points to no evidence

that, had the ALJ developed the record further, would have been

adduced at the hearing and that could have changed the result.               We

will not reverse the decision of an ALJ for lack of substantial

evidence where the claimant makes no showing that he was prejudiced

in any way by the deficiencies he alleges. Id.1

                                      III

      Having carefully reviewed the record, we conclude that the

decision of the ALJ, denying Brock's claim for SSI disability

benefits, is supported by substantial evidence and comports with

relevant legal standards.        Accordingly, the order of the district

court granting the Commissioner's motion for summary judgment is

AFFIRMED.




      1
            Brock also alleges that he did not receive adequate notice of his
right to counsel, and thus that the district court erred by finding that Brock
waived his right to counsel at his hearing before the ALJ. An SSI claimant is
entitled to adequate notice of his right to counsel at a hearing before an ALJ.
Clark v. Schweiker, 652 F.2d 399, 403 (5th Cir. 1981).       Generally, without
adequate notice a claimant cannot be held to have validly waived his right to
counsel. Id. at 404. However, as in the case of an unrepresented claimant
generally, a claimant who does not validly waive his right to counsel must prove
that he was prejudiced thereby in order to merit reversal of the ALJ's decision.
Kane, 731 F.2d at 1220 (citing Herridge v. Richardson, 464 F.2d 198 (5th Cir.
1972)). Brock points to no evidence that would have been adduced and that could
have changed the result had Brock been represented by counsel.       Thus, even
assuming that Brock did not validly waive his right to counsel, his lack of
representation does not require us to find that the decision of the ALJ was not
supported by substantial evidence.
