Risk factorsBy Mayo Clinic staff
Although the precise cause of disorganized schizophrenia isn't known, certain factors seem to increase the risk of developing or triggering the condition, including:
- Having a family history of schizophrenia
- Exposure to viruses while in the womb
- Poor nutrition while in the womb
- Stressful life circumstances
- Older paternal age
- Taking psychoactive drugs during adolescence
Signs and symptoms of schizophrenia typically develop between the teenage years and the mid-30s, although disorganized schizophrenia may start earlier.
