How to prevent psychosis?

The psychiatrist at Columbia University Ezra S. Susser is conducting a follow-up of child development "high risk" in trying to identify early warning signs that may help prevent psychosis.
Those who seem more involved in the psychotic disorder are:

• complications during birth.
• Difficulties in maintaining attention.
• Poor coordination muscle.
• Conduct emotionally unpredictable.
• Mother with schizophrenia serious and lasting.
• Separation or divorce of parents.
• Behavior revolt or retracted.
• Games and lonely little relation to other children.
