10%: Schizophrenia is a brain disease which affects 1% of the population and can be hereditary. According to excellent studies on twins, a person has about a 10% chance of having schizophrenia if one parent has it. The odds can go as high as 50% if both parents have schizophrenia. Also, it is possible to have schizophrenia in the absence of any family history for the disease.
