Abstract
The sex, education, clinical course, and results of the Wechsler Adult Intelligence Scale (WAIS) of 46 mildly retarded and/or borderline intelligence patients, were investigated. The subjects were 34 inpatients and 12 outpatients treated from April 1, 1984 to December 31, 1990 at Juntendo University Hospital and Juntendo Koshigaya Hospital both affiliated to Juntendo University.
There were more female patients than male patients.
The average age of first onset was 21 years old both for males and females. There was no relationship between age of first onset and intelligence.
Among the WAIS low rank examinations, significantly low marks were obtained in vocabulary than the other low rank examinations except for arithmetic.
With respect to the relationship between education and intelligence, high school graduates or more highly educated had significantly higher intelligence than junior high school graduates.
The common mental causes were human relations, poor marks in school work, physical diseases, and accidents.
The common figures of conditions were mental anxiety condition, hysteria, and delusion in this order.
Intelligence of subjects presenting with a mental anxiety condition was significantly higher than that of subjects presenting with hysteria.
There was no significant relationship between the prognosis and intelligence.
Social environmental factors were thought to establish the psychogenic reactions. The stronger the limitation became, more immature became the condition. There were frequent transitions among individual conditions with no consistent depression. The prognosis was not affected by intelligence. It was rather affected by the attitude of family members and adjustment to social environment. Further longterm follow-up investigations were considered to be necessary on these points.
