Before SCHWAB, C.J., and JOHNSON, GILLETTE and ROBERTS, JJ.
ROBERTS, Judge.
Appellant seeks reversal of an order declaring him to be a mentally ill person and committing him to the custody of the Oregon Mental Health Division. Two assignments of error are raised. The procedural issue we do not reach. We consider only the second assignment of error in which appellant contends the evidence does not establish that he is mentally ill beyond a reasonable doubt because it is insufficient to prove that he is dangerous to himself or others as required by ORS 426.005(2).[1] The trial court found no evidence that appellant was dangerous to others, but did find him dangerous to himself and unable to care for himself. We review de novo, State v. O'Neill, 274 Or. 59, 545 P.2d 97 (1976).
Appellant, a 29-year-old male, was described variously as "suspicious," "confused," and "disoriented in his thinking and judgment." Appellant's mother, an initiating petitioner, testified that appellant heard voices, feared animals, feared living alone and drank to excess. She stated that she no longer wished appellant to live in her house, but knew of no one who would take him in.
Appellant testified that his drinking problem was now under control, that he was not afraid to live alone and was interested in finding an apartment. Appellant, who has received psychiatric care at Dammasch and the Veteran's Administration Hospital in the past, expressed a willingness to undergo voluntary treatment.
The only violent act attributable to appellant was an act of violence against property. *94 His mother testified that he had entered her home, which was his residence at the time, by breaking a window. The incident, as recounted by appellant and his mother, occurred when she purposely locked him out of the house in order to prevent his return. Finding the door locked and being unable to arouse his mother from sleep, appellant broke the window in order to escape a very wet and cold night.
The other specific behavior alluded to by the court was an unannounced entry by appellant into a neighbor's apartment. Appellant testified that he knocked on the door and entered when he thought he heard someone invite him in. Once inside, appellant waited quietly for the person who lived there to come into the living room, but in fact, there was no one in the apartment. A few minutes later the owner arrived and was upset that appellant was in the living room. The trial court observed that "[a] man who enters somebody else's apartment is apt to have his head blown off," and concluded that appellant is therefore dangerous to himself.
The only evidence of appellant's behavior came from appellant himself or his mother. Although the mother initiated the commitment procedure, she testified that appellant can take care of himself. As for the two incidents set out above and upon which the court relied, we find from appellant's explanation that it was, at most, only unusual behavior.
The only other evidence is the reports of the two medical examiners. The reports were prepared on standard forms and contained the following information. The underscored matter are the questions propounded in the form.
Dr. Swenson's Report:


  "(1) Presenting Problem:
         Irresponsible behavior. (Breaking windows)

                          safety.

  "(6) Conclusions: Based upon the findings hereinabove
       set forth, I
       (X) do ( ) do not  find that the person has a mental
                          disorder, and
       (X) is ( ) is not  dangerous to self and or others, or
       ( ) is (X) is not  able to provide for his basic personal
                          needs and is not now receiving such
                          care as is necessary for his health or
                          safety.
  "(7) Recommendation: If mentally ill, specify type of
                       treatment facility best calculated to help
                       the person recover from his mental
                       illness.
         Advise continual custodial care under a guardianship
         arrangement and under mental supervision for counseling
         and medication.
  "It is my opinion that this person ( ) would ( ) would not
  cooperate with and benefit from a program of voluntary
  treatment."

Dr. Swenson's report tells us only that the appellant suffers from "depression" and is "irresponsible," and that from this he concludes appellant is mentally ill, a danger to himself or others and unable to provide for his personal needs. Dr. Munroe describes *95 a different mental and emotional state, i.e., "confused  fears," but reaches the same conclusions. Conceding the appellant may have some mental problems, there is no indication showing on what basis the physicians reached the conclusion the appellant was a danger to himself or others and could not care for himself. The evidence of the appellant's observed behavior belies their conclusions. Unlike State v. Troupe, 36 Or. App. 875, 586 P.2d 95 (1978), the nexus between the evidence and the experts' conclusions is not apparent. A more detailed statement of the experts' reasons is necessary if we are to be persuaded beyond a reasonable doubt.
Reversed.
