Bipolar disorder Symptoms and Causes

Bipolar disorder Symptoms and Causes: Bipolar disorder, also called manic depression, is a mental illness that is characterized by severe mood swings, repeated episodes of depression, and at least one episode of mania. Bipolar disorder is one kind of mood disorder that afflicts more than 1% of adults in the United States, up to as many as 4 million people.

Symptoms: The exact symptoms of bipolar disorder vary from person to person. For some people, depression causes the most problems; for other people manic symptoms are the main concern. Symptoms of depression and symptoms of mania or hypomania may also occur together. This is known as a mixed episode.

Causes: Several factors seem to be involved in causing and triggering bipolar episodes:
• Biological differences. People with bipolar disorder appear to have physical changes in their brains. The significance of these changes is still uncertain but may eventually help pinpoint causes.
• Neurotransmitters. An imbalance in naturally occurring brain chemicals called neurotransmitters seems to play a significant role in bipolar disorder and other mood disorders.
• Hormones. Imbalanced hormones may be involved in causing or triggering bipolar disorder.
• Inherited traits. Bipolar disorder is more common in people who have a blood relative (such as a sibling or parent) with the condition. Researchers are trying to find genes that may be involved in causing bipolar disorder.
• Environment. Stress, abuse, significant loss or other traumatic experiences may play a role in bipolar disorder.
