My sister was diagnosed with Obsessive-compulsive disorder. Are you familiar with OCD?
I actually am! My husband has problems with door-checking and hand-washing, ever since childhood.
Interesting, my sister was only recently diagnosed. Can you tell me more about the disorder?
Obsessive–compulsive disorder
Obsessive–compulsive disorder (OCD) is a mental disorder in which a person feels the need to perform certain routines repeatedly (called "compulsions"), or has certain thoughts repeatedly (called "obsessions"). The person is unable to control either the thoughts or activities for more than a short period of time. Common compulsions include hand washing, counting of things, and checking to see if a door is locked. Some may have difficulty throwing things out. These activities occur to such
a rewarding stimulus, whereas in OCD a compulsion is a facet of the disorder. The most common compulsions for people suffering from OCD are washing, and checking.
While not all compulsive behaviors are addictions, some such as compulsive sexual behavior have been identified as behavioral addictions.
Occurrence.
About 50 million people in the world today appear to suffer from some type of obsessive-compulsive disorder. Sufferers are often more secretive than other people with psychological problems, so the more serious psychological disorders are diagnosed more often.
