As a matter of fact the delinquencies in this patient reach back to early childhood and as there is no evidence of congenital syphilis it cannot be held that syphilis had any bearing in the causation of symptoms. Even were the delinquencies only of recent date it is doubtful if the court would take cognizance of the laboratory findings in the absence of definite mental symptoms. In this connection it may be stated that the court takes cognizance only of the acts of a patient at time of examination, and not of the history or laboratory findings, in committing a person. We have had several patients who from history, physical signs and laboratory tests made the diagnosis of paretic neurosyphilis easy and yet who could not be committed because they were mentally clear at the time. Such patients may be of grave potential danger to themselves and families, and present numerous social problems. See case of Joseph Wilson (95). =JUVENILE PARETIC NEUROSYPHILIS (“juvenile paresis”) with initial trauma.= =Case 89.= Margaret Tennyson was a small girl of six years, described as having been normal until run down by a double-runner sled about 13 months before her arrival at the hospital. The change was stated to be remarkable. “She was as unlike her own self as darkness and daylight.” Once fat and sunny, talkative and demonstrative with her toys, now Margaret had become silent, sullen, worried, and of a violent temper, stubborn and unmanageable. It does not appear that the patient was seriously injured by the double-runner, as she was able to walk a short distance home. Shortly, however, she began to have trouble with her feet (diagnosed at the time as flat-foot), and thereafter her whole character and disposition changed. Upon arrival at the hospital, the patient walked with a typical scissors gait of spastic paraplegia.
