Consequently the individual learns to avoid these situations and this avoidance in turn reinforces the fear buy proscar 5 mg overnight delivery. Fear can also occur merely in anticipation of the anxiety-provoking situation and symptoms are not better explained by another mental or physical disorder order 5mg proscar with visa. Specific phobias- fear is experienced only in the presence of a particular object or situation. Onset is usually in childhood and prevalence in the elderly is estimated to range from 3. Anxiety is restricted to the presence of the specific phobic object or situation, all other diagnostic criteria are similar to those of social phobia. Panic disorder Panic attacks and panic disorder are rare and symptomatically less severe in the elderly, estimates of prevalence ranges from 0. However, the prominent physical symptoms of panic disorder may result in patients being referred instead to cardiologists, neurologists and gastroenterologists. In one study of cardiology patients with chest pain and no coronary disease, one third of those aged 65 and over met the criteria for panic disorder. Several attacks occur within a period of one month and symptoms are not better explained by another psychiatric or physical disorder. Panic attacks are often co-morbid with other psychiatric disorders, particularly depression, and it may be severe enough to mask depressive features. In addition the condition should not meet the criteria for other anxiety disorders, psychiatric or physical disorders. Onset in old age is rare, the majority starting before the age of 25 and usually running a chronic fluctuating course into old age especially if left untreated. Obsessional symptoms may appear at any age following head injury or cerebral tumour. The individual recognizes them as originating from his own mind but is unable to resist them despite repeated attempts at doing so.
