Open Captioning

Open captioning is a descriptive text format that follows a video presentation.  It provides
information about the words being spoken and additional sound effects.  Open
captioning is part of the video production and is always present.  Whereas closed
captioning requires the text portion to be turned on or activated.
Obsessive Compulsive Disorder

People with obsessive-compulsive disorder (OCD) have persistent, upsetting thoughts
(obsessions) and use rituals (compulsions) to control the anxiety these thoughts
produce. Most of the time, the rituals end up controlling them.

For example, if people are obsessed with germs or dirt, they may develop a compulsion
to wash their hands over and over again. If they develop an obsession with intruders,
they may lock and relock their doors many times before going to bed. Being afraid of
social embarrassment may prompt people with OCD to comb their hair compulsively in
front of a mirror-sometimes they get "caught" in the mirror and can't move away from it.
Performing such rituals is not pleasurable. At best, it produces temporary relief from the
anxiety created by obsessive thoughts.

Other common rituals are a need to repeatedly check things, touch things (especially in
a particular sequence), or count things. Some common obsessions include having
frequent thoughts of violence and harming loved ones, persistently thinking about
performing sexual acts the person dislikes, or having thoughts that are prohibited by
religious beliefs. People with OCD may also be preoccupied with order and symmetry,
have difficulty throwing things out (so they accumulate), or hoard unneeded items.

Healthy people also have rituals, such as checking to see if the stove is off several times
before leaving the house. The difference is that people with OCD perform their rituals
even though doing so interferes with daily life and they find the repetition distressing.
Although most adults with OCD recognize that what they are doing is senseless, some
adults and most children may not realize that their behavior is out of the ordinary.
