Medical Genetics Schizophrenia is equally represented in women and men the onset of the lIness generally occurs at a later age in women than in men(between ages 23 and 35 in women versus 18 to 25 for men) Not only do women generally present with schizophrenia at later ages but the phenomenon of late onset schizophrenia (40+ years) is almost entirely a female one

Medical Genetics Women tend to display more prominent mood symptoms and men more negative symptoms. In the first episode of schizophrenia, women are more likely to display intense irritability, anger, and sadness men are more likely to be withdrawn and emotionally apathetic After the first episode these distinctions begin to blur. PMs is not an indication of the onset of schizophrenia in women although the symptoms are strikingly similar

Medical Genetics Subtypes of Schizophrenia 1. Disorganized Type 2. Catatonic Type 3. Paranoid Type 4. Undifferentiated Type 5. Residual Type

Medical Genetics Subtypes of Schizophrenia 1. Disorganized Type 2. Catatonic Type 3. Paranoid Type 4. Undifferentiated Type 5. Residual Type

Medical Genetics Disorganized Type This subtype of schizophrenia is marked by significant regression to primitive, uninhibited, and disorganized behavior. Thumb-sucking, howling like a wolf, temper tantrums, creation of pornographic art and unreasonably strong cravings to suckle a female's breast are characteristic of this type
