OCD

  1. 1. Obsessive-Compulsive Disorder By: Abel Voicu
  2. 2. Definition <ul><li>An anxiety disorder where a person becomes trapped in a repetitive cycle of obsessions and compulsions that are difficult to overcome. </li></ul><ul><li>Obsessions- persistent thoughts, images, or impulses that invade someone’s consciousness despite efforts to suppress or control them. </li></ul><ul><li>Common obsessions: thoughts of committing violent acts, worries about germs, doubts </li></ul><ul><li>Compulsions- impulses to commit repetitive acts </li></ul><ul><li>Common compulsions: hand-washing, checking </li></ul>
  3. 3. History <ul><li>In the 1600s it was thought of as symptoms of religious melancholy and naughty thoughts </li></ul><ul><li>Pierre Janet and Sigmund Freud isolated OCD from the disorders it was grouped with </li></ul><ul><li>Continuing research is being done about the causes of OCD and better treatments </li></ul><ul><li>Recent research on mice points toward a genetic cause. A missing gene making a certain protein caused the mice to scratch and groom themselves compulsively until an OCD drug was introduced. </li></ul>
  4. 4. Diagnosis <ul><li>OCD can be distinguished from general anxiety because it is an intrusion, and also from phobias because they are focused on an external object. </li></ul><ul><li>OCD has been connected to psychosis because it can become an inner repeating voice with a personality in some people. </li></ul><ul><li>12% of OCD patients are schizophrenic and 40% had symptoms of OCD before going into psychotic delusions </li></ul><ul><li>OCD runs in families and 1/3 of cases begin in kids </li></ul><ul><li>2.3% of Americans have OCD in a given year </li></ul><ul><li>People with OCD are diagnosed by a mental health professional </li></ul>
  5. 5. Causes <ul><li>OCD is no longer believed to be caused by life experiences. </li></ul><ul><li>Modern research suggests a biological and neurological cause </li></ul><ul><li>fMRI scans show the circuit connecting the amygdala, frontal cortex, caudate nucleus (motor control), and thalamus is abnormally active in people with OCD. </li></ul><ul><li>Genetic research on families with OCD members have found a genetic link. </li></ul><ul><li>There’s a link between OCD and other tick disorders such as Tourette’s. </li></ul>
  6. 6. Freud’s View <ul><li>A patient's mind responds maladaptively to conflicts between unacceptable, unconscious sexual or aggressive id impulses and the demands of conscience and reality </li></ul><ul><li>The ego defends against the id by isolation and reaction formation </li></ul><ul><li>The imperfect success of the ego gives rise to OCD symptoms </li></ul>
  7. 7. Treatment <ul><li>Pharmacotherapy- treatment using drugs that affect the neurotransmitter serotonin decrease the symptoms of OCD. </li></ul><ul><li>Selective serotonin reuptake inhibitors (SSRIs) such as fluoxetine (Prozac) and sertraline (Zoloft) prevent excess serotonin from being pumped back into neurons causing it to bind to receptor sites that regulate anxiety. </li></ul><ul><li>Disadvantage: Once medication is stopped, symptoms usually re-occur so the person needs to be put on medication indefinitely. </li></ul>
  8. 8. Treatment <ul><li>Behavior Therapy- &quot;exposure and response prevention“ where the patient deliberately confronts their feared object or idea. </li></ul><ul><li>Ex: OCD hand washer touched “contaminated” object and is forced to not was hands until anxiety goes down. </li></ul><ul><li>Behavior therapy is successful for most patients as long as the therapist is fully trained and the person is highly motivated and has a positive attitude. It lasts longer after treatment than drug therapy. </li></ul><ul><li>Cognitive-behavioral- therapy emphasizing changing the OCD’s patient’s beliefs and thinking patterns. </li></ul>
  9. 9. Related Disorders <ul><li>Anorexia and bulimia nervosa </li></ul><ul><li>Tourette syndrome </li></ul><ul><li>Trichotillomania (urge to pull out hair) </li></ul><ul><li>Body dysmorphic disorder (preoccupation with minor defect in appearance) </li></ul><ul><li>Obsessive-compulsive personality disorder (psychological rigidity, perfectionism, and excessive orderliness) </li></ul><ul><li>Depression </li></ul>
