Treatment Options

Obsessive-compulsive disorder has a slow onset and in most cases takes years for the symptoms to reach the full-blown stage. However, in some individuals there is a rapid onset of symptoms associated with a traumatic event such as a loss or pregnancy. Unfortunately, individuals with OCD often keep their condition secret and it can take years until they seek treatment. A poor prognosis is registered in individuals that yield rather than resist to compulsions.

There are several treatment options available for individuals with obsessive-compulsive disorder, such as: medication, psychotherapy, and neurosurgical treatment.

Medication: Most individuals with OCD benefit from certain psychiatric medication. This treatment approach is directed towards a specific receptor deficit. The first-line medication prescribed in individuals with OCD is serotonergic in nature (it targets the serotonin). Common serotonin type medicines include:

  • Selective serotonin reuptake inhibitor (SSRI's) such as fluoxetine (Prozac), fluvoxamine (Luvox), sertraline (Zoloft), paroxetine (Paxil), citalopram and escitalopram (the last two are not yet FDA approved).

  • Tricyclic antidepressants (Anafranil) was one of the first anti-obsession drugs prescribed in the UK, but is less prescribed now due to their unpleasant side effects. It is usually recommended when the treatment with SSRI's have failed.

  • Serotonin norepinephrine reuptake inhibitor (SNRI) such as venlafaxine and duloxetine are used only in clinical trials, because they are not FDA approved.

The benefit of antidepressant treatment is that it balances the level of serotonin in the brain. However, this treatment is not followed by a complete remission of the symptoms, but rather a reduction (30 to 50 percent). Also, the results tend to be noticed after several weeks of treatment and the treatment has to be followed for at least 10 to 12 weeks.

Psychotherapy: The most effective psychological treatment that individuals with OCD can benefit from are: behavioral therapy and cognitive behavioral therapy.

  • Behavioral therapy is not a traditional psychotherapy but it focuses on modifying or "unlearning" those maladaptive behaviors that cause psychological discomfort. It is usually the first-line therapy treatment for individuals with OCD. Obsessive-compulsive disorder can be treated with a behavioral therapy approach called "exposure and response prevention" which involves two major steps: (1) graduate exposure to those stimuli that create tension, and (2) prevents the engagement into typical response that cause temporary relief. The exposure step is conducted in safe, comforting, and confidential settings where the individuals face their anxiety or distress causing stimuli, either direct or through imagination. The "exposure and response prevention" technique is based on the idea that the therapeutic effect is achieved as the individual confronts their fears and discontinue their escape response. The goal of this technique is habituations (getting used to something that used to produce anxiety or distress).

    Behavioral therapy has proven to bring long lasting benefits for individuals with OCD. However, this form of therapy is beneficial when the individual with OCD is fully motivated when they start the therapy, and they have a cooperative family.

  • Cognitive behavioral therapy is another option for individuals with OCD. This form of psychotherapy is based on learning principles and experience. Cognitive behavioral therapy considers that our thoughts and not the external situations, people or events, trigger the behavior and feelings. This form of therapy combines methods from behavioral and cognitive therapies for better outcomes.

    Cognitive behavioral therapy for individuals with OCD is focused around two aspects (1) exposure and prevention, and (2) cognitive restructuring, both supported by laboratory research and clinical trials conducted on adults and children. The exposure and prevention technique is adopted from the behavioral therapy and creates a safe setting for the individuals with OCD to face the feared stimuli and cope with the anxiety and stress by not engaging in the compulsive rituals. The cognitive restructuring technique helps the individual to identify disruptive thoughts associated with distress, and replace them with realistic, functional thoughts.

    Cognitive behavioral therapy is an effective treatment approach that works in 60 to 85 percent of the individuals with OCD both adults and children.

In rare cases, when individuals with OCD do not respond to medication or psychotherapy, they can be exposed to electroconvulsive therapy (ECT). This therapy involves delivering electric shocks to the subject's brain through electrodes attached to the head. The shock causes a seizure which alows the neurotransmitters to released in the brain.

Neurosurgical treatment: This is a option limited to a small number of individuals with OCD when they don't respond to other treatment options and their symptoms are severe and refractory.

  • Bilateral cingulotomy: This is a surgical procedure where the pathway in the brain responsible for OCD symptoms is being interrupted.
  • Stereotactic radiosurgery: This procedure involves emitting hundreds of powerful, highly focused gamma radiation beams into the brain area involved in OCD symptoms through a non-surgical machine (called Gamma knife).
