Obsessive-Compulsive Disorder (OCD)
What Is It?
In obsessive-compulsive disorder (OCD), a person is troubled by intrusive, distressing thoughts (obsessions) and feels the pressure to carry out repetitive behaviors (compulsions).
Neuroscientists believe that the brain pathways involved with judgment, planning and body movement are altered in OCD. Environmental influences, such as family relationships or stressful events, can trigger or worsen OCD symptoms.
