4 Social Anxiety Disorder Specific Phobias Social Anxiety Disorder / Phobias Fear exists in all cultures Fear appears to exist across most species The purpose of fear is to protect an organism from immediate threat and to mobilize the body for quick action to avoid danger and potential harm. Anxiety, on the other hand, is a future-oriented mood state in which the individual anticipates the possibility of threat and experiences a sense of uncontrollability focused on the upcoming negative event. Fear and anxiety are not always adaptive. A marked and persistent fear of one or more social or performance situations in which the person is exposed to unfamiliar people or to possible scrutiny by others The person recognizes that the fear is excessive or unreasonable The feared experiences are avoided or are endured with intense anxiety or distress, and often interfere with the person s normal routine or employment/school Specific Phobias Treatment of Social Anxiety Disorder and Phobias Lifetime Prevalence with Specific Fear Heights 6% Flying 4% Closed spaces 4% Being alone 3% Storms 3% Animals 6% Blood 4.5% Water 3% ANY 11.3% Cognitive Behavioral Therapy (CBT) Desensitization reprogramming SSRI s Venlafaxine or SNRI s Benzodiazepines MAOI s Gabapentin Beta blockers Obsessive Compulsive Disorder Treatment of OCD An often debilitating disorder The presence of two distinct phenomena The most common obsession is contamination of some type The types of obsessions and compulsions are remarkably consistent across cultures Specific forms / categories Contamination / germs Need for symmetry Somatic obsessions, GI, facial or body features, picking Sexual and aggressive obsessions Pathological doubt Pharmacotherapy, for striking serotonin deficiency syndromes SSRI s The high velocity rifle against anxiety SNRI s of benefit for some people Tricyclics (desipramine) The Abrams tank MAOI s The nuclear weapons against anxiety, panic and OCD.

5 Treatment for OCD Which SSRI to Choose? Importance of Treatment Sertraline mg / day Fluvoxamine mg / day Citalopram 40 mg / day Escitalopram mg / day Fluoxetine mg / day Paroxetine mg / day (Not in women) No woman during her child bearing years should be prescribed Paroxetine or Divalproex without appropriate, detailed, written informed consent. Document and document some more. Giving the package insert to the patient (and documenting you did so) is your friend. Untreated anxiety or depressive disorders lead to brain inflammation and some degree of brain atrophy in most patients. Interleukin 6 markers in mood disorders research. The Danish study looked at every person in Denmark hospitalized for depression or bipolar disorder over 30 years and looked at how many of those patients developed dementia, compared with matched controls. Each episode of depression (or hypomania) increased risk for dementia by 6% - 13% per episode. Treating major depression, all anxiety disorders, and bipolar disorder reduces the likelihood someone may develop Alzheimer's or other dementias later in life. Thank you! Q & A Chris Ticknor, MD 4
