Dr. Charles Nemeroff
Psychiatry 40 years experience
Disorders differ: The genetic contribution to psychiatric disorders range from 67% for bipolar disorder to 50% for schizophrenia and 33% for depression. All of these disorders are a product of both environmental factors and genetics.
Dr. Aron Tendler
Psychiatry 19 years experience
Depends On Diagnosis: The probability depends on the specific diagnosis and how heritable it is. Most psychiatric disorders are caused by an interaction of multiple genes and stress. Even identical twins will not necessarily have the same diagnosis. For example in schizophrenia there is a 40% chance that one twin will not get it. Even if both parents have a diagnosis it does transmit at a high rate.
