Childhood Schizophrenia

Neuropsychological functioning in adolescents with first episode psychosis: A two-year follow-up study

“…In the case of full-scale IQ, which the authors used as a measure of general cognitive function, the decrease in negative symptoms explained the 8% variance of its improvement. Fluctuations in cognitive performance secondary to both positive [25] and negative [12,20] symptom changes have also been reported in other longitudinal studies. In short, psychotic symptoms, although not the cause of cognitive impairment, play a moderate modulating role in cognitive performance.…”

Concepts of Autism: A Review

“…However, 21% of Kolvin's sample (1971b) exceeded the upper level of educational subnormality (I.Q. 70), compared with 29% (Rutter 1966) and 39% (Gittelman and Birch, 1967) found by other workers. Islets of intelligence such as normal or superior scores in an otherwise depressed intellectual performance on some performance tests have also been reported .…”

Neuropsychological test results associated with psychiatric disorders in adults.

“…G. Small & Small, 1965;Tucker, Detre, Harrow, & Glaser, 1965), pneumoencephalograms (e.g., Haug, 1963;Moore, Nathan, Elliott, & Laubach, 1933), and histopathologic studies of the brain (e.g., Tatetsu, 1964;Wildi, Linder, & Costoulas, 1967). Also relevant are studies that have suggested a relationship in some cases between the early onset of schizophrenia and early known or possible insults to the brain (Gittelman & Birch, 1967;Lane & Albee, 1966;Mednick, 1970;Pollin et al, 1968). Several recent reviews of neurological findings with schizophrenics make it unnecessary to discuss them in more detail here (Mirsky, 1969;Pincus & Tucker, 1974;Reitan, 1976;Wolf & Berle, 1976).…”
