The risk of a mental illness increases if one or more of your family members have a mental disorder, but this increased risk doesn't guarantee that you will develop a mental illness. Not only have some mental illnesses been found to be hereditary in nature, but certain studies have found that some major mental illnesses can be traced to the same genetic variations.
Some hereditary psychiatric disorders are:
1. Obsessive compulsive disorder
Obsessive-compulsive disorder or OCD is a disorder of the brain and behavior. A person suffering from OCD has uncontrollable, recurring thoughts and behaviors they cannot stop repeating. Ocd also causes severe anxiety in such people. In 2000, a study conducted by researchers in Washington d. C. And Baltimore concluded that having one or more ocd family member (s) may increase the chances of you developing it too. In 2010, a study tracked down possible chromosomes that may be responsible for OCD.
Schizophrenia is a chronic mental illness that affects and dictates how a person feels, thinks and behaves. Those suffering from schizophrenia may lose touch with reality and experience delusions, hallucinations, thought disorders and movement disorders. It has been seen that people who have an identical twin with schizophrenia are 50% more likely to develop the disorder and those who have one parent suffering from schizophrenia are 18% more likely to inherit the illness.
