Except for his reclusiveness and antisocial behavior, his psychiatric and cognitive assessment elicited no abnormalities (Mini-Mental State Examination [8] and non-verbal test of intellectual functioning, Raven’s Standard Progressive Matrices [9]). Neuropsychological testing that assessed his temporal organization of behavior and cognitive rigidity, such as the Modified Wisconsin Card Sorting Task and Verbal Fluency (Controlled Oral Word Association Test) [10], were all normal for his age and education. No neurological abnormalities were found.
