Twenty-nine children who had had California encephalitis were evaluated for intellectual functioning and visual-motor coordination two years after discharge from the hospital. They were compared with an equal number of out-patients selected from psychology files. For nine of the study patients, pre-illness measures were available for comparison.
No uniform effects of the illness were identified. The number of symptoms and laboratory findings during illness fails to correlate with the psychologic findings on follow-up. However, the presence of focal neurologic signs appears to be associated with higher performance IQs than verbal IQs (no instances of the opposite) and poorer visualmotor coordination.
