Risk factors
By Mayo Clinic staffAlthough the precise cause of disorganized schizophrenia isn't known, researchers have identified certain factors that seem to increase the risk of developing or triggering disorganized schizophrenia, including:
- Having a family history of schizophrenia
- Exposure to viruses while in the womb
- Malnutrition while in the womb
- Stressful life circumstances
- Trauma or abuse during childhood
- Older paternal age
- Taking psychoactive drugs during adolescence
According to the National Institute of Mental Health, schizophrenia affects about 1 percent of the population, and disorganized schizophrenia affects an even smaller percentage. Schizophrenia typically becomes apparent between the teenage years and the mid-30s, but disorganized schizophrenia tends to appear on the early end.
