Social Anxiety Disorder Epidemiology It is more common in women than in men (ratio about 3 to 2) . SAD has an early onset, peaking between ages 0 and 5 years, and again between ages 11 and 15 years; onset after age 25 years is rare. Behavioural inhibition, a personality style beginning in early childhood that involves a tendency to exhibit withdrawal and excessive autonomic arousal when presented with the unfamiliar,may be a precursor of SAD for some individuals.

The prevalence is 2% of the general population 5/23/2024 Takele T. 39
5/23/2024 Takele T. 40 Some example of OCD
DSM-V-TR Diagnostic Criteria for Obsessive-Compulsive Disorder A. Either obsessions or compulsions: Obsessions as defined by (1), (2), (3) and (4): 1. Recurrent and persistent thoughts, impulses, or images that are experienced, at some time during the disturbance, as intrusive and inappropriate and that cause marked anxiety or distress 5/23/2024 Takele T. 41
2. The thoughts, impulses, or images are not simply excessive worries about real-life problems 3. The person attempts to ignore or suppress such thoughts, impulses, or images, or to neutralize them with some other thought or action 4. The person recognizes that the obsessional thoughts, impulses, or images are a product of his or her own mind (not imposed from without as in thought insertion) 5/23/2024 Takele T. 42
Compulsions as defined by (1) and (2): 1. Repetitive behaviors (e.g., hand washing, ordering, checking) or mental acts (e.g., praying, counting, repeating words silently) that the person feels driven to perform in response to an obsession, or according to rules that must be applied rigidly 5/23/2024 Takele T. 43
2. The behaviors or mental acts are aimed at preventing or reducing distress or preventing some dreaded event or situation; however, these behaviors or mental acts either are not connected in a realistic way with what they are designed to neutralize or prevent or are clearly excessive 5/23/2024 Takele T. 44
Differential Diagnosis Psychotic symptoms …The keys to distinguishing OCD from psychosis are (1) patients with OCD can almost always acknowledge the unreasonable nature of their symptoms, and (2) psychotic illnesses are typically associated with a host of other features that are not characteristic of OCD. …Obsessive symptoms associated with depression are only found in the presence of a depressive episode, whereas true OCD persists despite remission of depression. 5/23/2024 Takele T. 45
Course and Prognosis More than half of patients with OCD have a sudden onset of symptoms. The onset of symptoms for about 50 to 70 percent of patients occurs after a stressful event, such as a pregnancy, a sexual problem, or the death of a relative. About one third of patients with OCD have major depressive disorder, and suicide is a risk for all patients with OCD. 5/23/2024 Takele T. 46
Course and Prognosis… About 20 to 30 percent of patients have significant improvement in their symptoms, and 40 to 50 percent have moderate improvement. The remaining 20 to 40 percent of patients either remain ill or their symptoms worsen . 5/23/2024 Takele T. 47
Psychotherapy Behavioral e.g. - relaxation training, -guided imaginary & exposure - Desensitization -thought stopping techniques Pharmacological: SSRIs e.g. fluoxetine TCA- Chlomipramine 5/23/2024 Takele T. 48
Post Traumatic Stress Disorder (PTSD) 5/23/2024 Takele T. 49
Post Traumatic Stress Disorder (PTSD) The defining feature of posttraumatic stress disorder is development of anxiety symptoms after an excessively distress life event that is experienced with terror, Fear, and helplessness. The event is serious. Example - Seeing a child killed (Involvement in a major:- earthquake, fire,Plane crash,war and rape) 5/23/2024 Takele T. 50
Epidemiology The lifetime incidence of PTSD is estimated to be 9 to 15 percent and the lifetime prevalence of PTSD is estimated to be about 8 percent of the general population The prevalence is much higher in areas where conflict has occurred, where it ranges from 16% to 37%(lifetime) Onset is generally in the mid to late 20s,and prevalence is higher among women than men. 5/23/2024 Takele T. 51
The World Health Organization’s Global Burden of Disease study predicted that exposure to traumatic events, such as motor vehicle accidents,war, and violence,will be the third, eighth, and twelfth leading causes of disability worldwide by the year 2020 The disorder is most likely to occur in those who are single, divorced, widowed, socially withdrawn, or of low socioeconomic level. 5/23/2024 Takele T. 52
Comorbidity Comorbidity rates are high among patients with PTSD, with about two thirds having at least two other disorders. Common comorbid conditions include depressive disorders, substance-related disorders, other anxiety disorders, and bipolar disorders. Comorbid disorders make persons more vulnerable to developing PTSD. 5/23/2024 Takele T. 53
Etiology 1.Stressor 2.Risk Factors Predisposing Vulnerability Factors in PTSD Presence of childhood trauma Inadequate family or peer support system Being female Genetic vulnerability to psychiatric illness Recent stressful life changes Recent excessive alcohol intake 5/23/2024 Takele T. 54
