Anxiety disorders panic

Unlike most anxiety disorders, panic disorder leads to a high utilization of general medical services, reflecting the frequency, severity and alarming nature of physical symptoms such as palpitations, gastrointestinal distress, respiratory problems and headaches (Zaubler and Katon, 1998). This can result in extensive investigations and sometimes inappropriate but expensive medications. 

The anxiety disorders are common and surprisingly disabling conditions. Studies on the health economics of generalized anxiety disorder, panic disorder, social anxiety disorders and obsessive compulsive disorder document the cost to the individual and to society. Attention has focused on the major psychiatric disorders such as depression, schizophrenia and the dementias. Studies suggest that many anxiety disorders are of early onset and too often chronic they are quite common and impose a heavy burden on society. More studies will be needed to discern the fine grain in the survey material and to identify more precisely the location and type of societal costs. These factors will vary from country to country, from district to district, between men and women and between various age groups.

It is uncertain whether, unlike generalized anxiety disorder, panic disorder and obsessive-compulsive disorder, social phobia has a genetic basis. 

Escitalopram was efficacious in patients with major depressive disorder in short-term, placebo-controlled trials, three of which included citalopram as an active control, and in a 36-week study in the prevention of relapse in depression (7). It has also been used to treat generalized anxiety disorder, panic disorder, and social anxiety disorder. Results also suggest that, at comparable doses, escitalopram demonstrates clinically relevant and statistically significant superiority to placebo treatment earlier than citalopram. The most common adverse events associated with escitalopram include nausea, insomnia, disorders of ejaculation, diarrhea, dry mouth, and somnolence. Only nausea occurred in more than 10% of patients taking escitalopram. 

Clinicians will readily recognize in Table 3.7 the experiences reported by many of their patients when receiving treatment for depression or other related psychiatric disorders. By looking at the Function affected column, it is possible to understand why some medications (say, SSRIs) are effective in variable degrees in several conditions associated with serotonin dysfunction (depression, OCD, social anxiety disorder, posttraumatic stress disorder, generalized anxiety disorder, panic disorder, and bulimia nervosa). 

Other psychiatric illnesses, particularly the anxiety disorder, are also risk factors for development of major depressive disorder. Persons with anxiety disorders (panic disorder, obsessive compulsive cUsorder, social phobia, generalized anxiety disorder, and posttrauma tic stress disorder) go on to develop major depressive cUsorder over the course of 5-20 years in over 50% of cases.

The Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision classifies anxiety disorders into several categories generalized anxiety disorder, panic disorder (with or without agoraphobia), social anxiety disorder, specific phobia, OCD, PTSD, and acute stress disorder (ASD). The characteristic features of these illnesses are anxiety and avoidance behavior. Generalized anxiety disorder, panic disorder, and social anxiety disorder are discussed in Chap. 69. 

The primary uses for the SSRIs include MMD and bipolar depression (fluoxetine, paroxetine, sertraline, and citalopram), atypical depression (i.e., depressed patients with unusual symptoms, e.g., hypersomnia, weight gain, and interpersonal rejection sensitivity fluoxetine, paroxetine, sertraline, and citalopram), anxiety disorders, panic disorder (sertraline and paroxetine), dysthymia, premenstrual syndrome, postpartum depression, dysphoria, bulimia nervosa (fluoxetine), obesity, borderline personality disorder, obsessive-compulsive disorder (fluvoxamine, fluoxetine, paroxetine, and sertraline), alcoholism, rheumatic pain, and migraine headache. Among the SSRIs, there are more similarities than differences however, the differences between the SSRIs could be clinically significant.
