London, Sep 21 : having a sibling with mental disorders may be at an increased risk of developing the condition, a study has warned.

Schizophrenia is a serious disorder which affects how a person thinks, feels and acts. Someone with schizophrenia may have difficulty distinguishing between what is real and what is imaginary; may be unresponsive or withdrawn; and may have difficulty expressing normal emotions in social situations
According to study  held at e European College of Neuropsychopharmacology (ECNP) congress in Vienna, a sibling with schizophrenia increases a person’s risk of developing the condition by ten times.

They also have six to eight times increased chance of suffering from schizoaffective disorder — symptoms of both schizophrenia and a mood disorder — and seven to 20 times greater risk of suffering from bipolar disorder than the general population.

If a brother or sister suffers from bipolar disorder, then their siblings have four times greater chance of suffering from bipolar disorder, schizophrenia, and other psychiatric disorders.

“This is a large study which allows us to put meaningful figures on the risks of developing mental disorders after they have arisen in a brother or sister,” said lead researcher Mark Weiser, Professor at the Tel Aviv University in Israel.

In the study, the team examined the rates of mental disorders in the families of 6,111 Israeli patients who had been hospitalised with schizophrenia, bipolar disorder, or depression.
