bipolar genetic disorder

schizophrenia is genetic? Is bipolar disorder genetic? If any of them are, are there tests that can show you?
is passed to a son or not?
Dolphin is totally wrong about schizophrenia. Genetics is the "fashion" in modern science and there is no link final between schizophrenia and inheritance. The cause (s) of schizophrenia (which is not a single disorder but a range of them) is not known to medical science as there can be no physical or genetic test for schizophrenia. The diagnosis of a form of schizophrenia is a purely subjective opinion of a psychiatrist. Look up "schizophrenia" in a search on the Web! Yahoo. Wikipedia has a good summary. Also read John Horgan, The Undiscovered Mind "how the human brain defies replication, medication, and explanation: Free Press, New York NY, 1999 to learn how little science knows about the mind and brain. Stop worrying that you're right!
