Psychiatric Illnesses May Be Genetic
Researchers have discovered that five major psychiatric disorders share common genetic risk factors.
The largest ever genetic study of psychiatric illness found autism, attention deficit-hyperactivity disorder, bipolar disorder, major depressive disorder and schizophrenia shared several risk factors.
In particular, researchers found two genes involved in the balance of calcium in the brain may play a role in some of the disorders.
They say the discovery could lead to new treatments.
