An anxiety disorder in which people have unwanted and repeated thoughts, feelings, ideas, sensations (obsessions), or behaviors that make them feel driven to do something (compulsions).Disorder may also be called as Obsessive-compulsive neurosis; OCD.
Often the person carries out the behaviors to get rid of the obsessive thoughts, but this only provides temporary relief. Not performing the obsessive rituals can cause great anxiety.
Obsessive-compulsive disorder (OCD) is more common than was once thought. Most people who develop it show symptoms by age 30.There are several theories about the cause of OCD, but none have been confirmed. Some reports have linked OCD to head injury and infections. Several studies have shown that there are brain abnormalities in patients with OCD, but more research is needed.About 20% of people with OCD have tics, which suggests the condition may be related to Tourette syndrome. However, this link is not clear.
Pathophysiology
OCD can be interpreted in the light of physiology after consideration of various approaches (phenomenology, neuropsychology, neuroimmunology and neuroimagery) that contribute to proposing the central role of several cortical and subcortical regions, especially the orbitofrontal cortex (OFC), the anterior cingulate cortex (ACC), the dorsolateral prefrontal cortex (DLPC), the head of the caudate nucleus and the thalamus. The OFC is involved in the significance attributed to the consequences of action, thereby subserving decision-making, whereas the ACC is particularly activated in situations in which there are conflicting options and a high likelihood of making an error. The DLPC plays a critical part in the cognitive processing of relevant information. This cortical information is then integrated by the caudate nucleus, which controls behavioral programs. A dysfunction of these networks at one or several stages will result in the emergence and maintenance of repetitive thoughts and characteristic OCD behavior.
Signs and tests
Your own description of the behavior can help diagnose the disorder. A physical exam can rule out physical causes, and a psychiatric evaluation can rule out other mental disorders.

Questionnaires, such as the Yale-Brown Obsessive Compulsive Scale (YBOCS), can help diagnose OCD and track the progress of treatment.
Treatment
OCD is treated using medications and therapy.
The first medication usually considered is a type of antidepressant called a selective serotonin reuptake inhibitor (SSRI). These drugs include:
Note:
warning about taking cautions regarding use of medicine
Cognitive behavioral therapy (CBT) has been shown to be the most effective type of psychotherapy for this disorder. The patient is exposed many times to a situation that triggers the obsessive thoughts, and learns gradually to tolerate the anxiety and resist the urge to perform the compulsion. Medication and CBT together are considered to be better than either treatment alone at reducing symptoms.
Psychotherapy can also be used to:

Symptoms
- Obsessions or compulsions that are not due to medical illness or drug use
- Obsessions or compulsions that cause major distress or interfere with everyday life
- There are many types of obsessions and compulsions. Examples include:
- Checking and rechecking actions (such as turning out the lights and locking the door)
- Excessive counting
- Excessive fear of germs
- The compulsion to repeatedly wash the hands to ward off infection
- The person usually recognizes that the behavior is excessive or unreasonable.

Treatment
OCD is treated using medications and therapy.
The first medication usually considered is a type of antidepressant called a selective serotonin reuptake inhibitor (SSRI). These drugs include:
- Citalopram (Celexa)
- Fluoxetine (Prozac)
- Fluvoxamine (Luvox)
- Paroxetine (Paxil)
- Sertraline (Zoloft)
If an SSRI does not work, the doctor may prescribe an older type of antidepressant called a tricyclic antidepressant. Clomipramine is a TCA, and is the oldest medication for OCD. It usually works better than SSRI antidepressants in treating the condition, but it can have unpleasant side effects, including:
- Difficulty starting urination
- Drop in blood pressure when rising from a seated position
- Dry mouth
- Sleepiness
Note:
warning about taking cautions regarding use of medicine
- if one medicine donot respond or treats the disorder then in such cese medicine category should be changed but it should be kept in mind that before starting next category patient should take a gap of almost two week so that previous medicine eliminates totaly from blood.
- combination of two different medicine to treat such dis order is highly not authorized(contraindicated)
Cognitive behavioral therapy (CBT) has been shown to be the most effective type of psychotherapy for this disorder. The patient is exposed many times to a situation that triggers the obsessive thoughts, and learns gradually to tolerate the anxiety and resist the urge to perform the compulsion. Medication and CBT together are considered to be better than either treatment alone at reducing symptoms.
Psychotherapy can also be used to:
- Provide effective ways of reducing stress
- Reduce anxiety
- Resolve inner conflicts
Expectations (prognosis)
OCD is a long-term (chronic) illness with periods of severe symptoms followed by times of improvement. However, a completely symptom-free period is unusual. Most people improve with treatment.
Complications
Long-term complications of OCD have to do with the type of obsessions or compulsions. For example, constant handwashing can cause skin breakdown. However, OCD does not usually progress into another disease.
