Bipolar disorder, also known as manic-depressive illness, is a complex brain disorder that involves sudden mood shifts from high to low. These dramatic mood swings, known as episodes, are referred to as stages of mania and depression. Bipolar disorder affects over five million Americans.
Obsessive Compulsive Disorder (OCD) is a condition in which someone has uncontrollable, excessive thoughts (obsessions) that can lead to repetitive behaviors (compulsions). Someone who is diagnosed with OCD may find themselves in a cycle of repeating certain behaviors to neutralize the obsessive thoughts. This can be time consuming, and may interfere with a person’s daily life.
Post-Traumatic Stress Disorder (PTSD) is a condition that can develop in some people after going through a shocking, scary, or dangerous event. While it is normal to experience adverse and/or emotional reactions after experiencing trauma, over time these symptoms should regulate themselves and eventually get better. Someone with PTSD, however, may experience worsening of symptoms, in which the symptoms are lasting for months or years after the event and may start interfering with their daily life.
