Age of onset of schizophrenia varies among people, but occurs in early adulthood for the vast majority of people--typically between the ages of 16 and 30. While schizophrenia affects men and women in equal numbers, symptoms tend to begin at a younger age for men.
Men and women show different patterns of susceptibility for developing schizophrenic symptoms. Males reach a single peak of vulnerability for developing schizophrenia between the ages of 18 and 25 years. In contrast, female vulnerability peaks twice; first between 25 and 30 years, and then again around 40 years of age.
