P A Rizzo, and M Spadaro, and G F Albani, and C Morocutti

The CNVs of three disorganized schizophrenics and three paranoid schizophrenics were studied longitudinally over a 5-year period. The CNV of the disorganized-type schizophrenics reached its maximum decrease within 3 years of disease onset. A more gradual and less accentuated decrease was noted in the paranoid group within a span of 5 years.
