Organic brain syndrome (OBS) is a general term used to describe decreased mental function due to a medical disease, other than a psychiatric illness. It is often used synonymously (but incorrectly) with dementia.
Treatment depends on the disorder. Many of the disorders are treated mainly with rehabilitation and supportive care to assist the person in areas where brain function is lost.
Medications may be needed to reduce aggressive behaviors that can occur with some of the conditions.
See the specific disorder. Some disorders are short-term and treatable, but many are long-term or get worse over time.
People with OBS often lose the ability to interact with others or function on their own.
