Panic disorder is a disabling condition that is customary in patients in primary care settings. Diagnosis may be difficult because symptoms of that kind as chest pain and shortness of breath also are associated with potentially serious conditions. However, becoming diagnosis and treatment with medications and/or skilled therapy may restore a better quality of life.

Patients with panic disorder typically have panic attacks, with rapid attack of the symptoms listed in Table 1 (1) and a persistent touch about having an attack. Attacks befall suddenly and typically last more than 10 minutes (although the amplification of attacks is variable). They can come into view one to several times by week, usually unpredictably, and may interfere with the patient's normal activities and work. (2) Although panic disorder ofttimes is chronic, the frequency of attacks and associated symptoms (eg depression, avoidant behavior) may wax and wane.

Panic disorder, as defined by way of the Diagnostic and Statistical Manual of Mental Disorders, 4th ed (DSM-IV), affects 1 to 3 percent of the general population at a point in their lives. (3) These patients, however, use health care resources to a disproportionately high compass Psychiatric case-finding studies (4,5) of patients presenting to push departments with chest pain establish that 17 to 25 percent of these patients also met the criteria for panic disorder. In a large multi-center research (6) of primary care practices, the prevalence of panic disorder ranged from 1 to 6 percent across application of mind sites.

Panic disorder repeatedly occurs in patients with agoraphobia (26 percent) or social phobia (33 percent) which includes widespread anxiety about social interaction and performance. (2) Approximately common in three patients with panic disorder is bring lowed and one in five attempts suicide. (7) Although patients with panic disorder may self-medicate with alcohol, the lifetime prevalence of alcohol and substance abuse is not significantly different in this clump than in the general population. (8) With their array of somatic and affective question s patients with panic disorder may be an of the most complicated and time-consuming patients in a primary care setting.

exhibition of Panic Disorder

in what way do panic symptoms develop? A phobia of internal sensations is fancy to drive the patient's avoidance behavior. In addition to neurochemical and genetic moulds for the disorder, some researchers have propos a cognitive gauge in which patients learn to misinterpret meditations and emotions as physical symptoms. For example, a woman who is afraid of being left alone when her husband leaves for work may experience that fear physiologically (eg shortness of breath, sweating), which in move round makes her feel more anxious ("What is unfit with me?"), deepening the spiral and leading to more symptoms. Another theory is that patients escalate otherwise benign carcass sensations into panic attacks (the behavioral model) For example, a man whose heart rate accelerates when he becomes angry may escalate that sensation and the resulting anxiety into the chest pain of a "heart attack." as well-as; not only-but also; not only-but; not alone-but examples demonstrate the patient's phobia of internal sensations.

Treatment

Patients with panic disorder have several treatment options. Determining which treatment is best for a given patient is done by the agency of a shared decision-making process between the patient and physician. A allude toed approach to treatment is outlined in Figure 1

ANTIDEPRESSANTS

Antidepressant medications have been shown to change into panic severity, eliminate attacks, and improve overall quality-of-life measures in patients with panic disorder. (3) couple recent meta-analyses (9,10) found that selective serotonin reuptake inhibitors (SSRIs) and tricyclic antidepressants (TCAs) are equally effective in reducing panic severity and the number of attacks. In these studies, 61 percent of patients were panic-free after six to 12 weeks of treatment, compared with 41 percent of hinder patients. These studies differ onward whether SSRIs are better tolerated than TCAs. An earlier meta-analysis (11) fix SSRIs to be superior to TCAs. However, the benefits of SSRIs may have been overstated in the latter reflection because of its failure to account for publication bias (i.e., the greater likelihood that small studies finding no difference between treatments will not be published).

Table 2 (12) lists dosing and charge information for the antidepressants that have been prov in randomized controll trials (RCTs) to be effective in the treatment of panic disorder. The choice of antidepressant should be based onward side effect profiles and patient estimations Monoamine oxidase inhibitors also are effective in the treatment of panic disorder, further their use is limited by means of safety concerns.

COGNITIVE BEHAVIOR THERAPY

Cognitive behavior therapy (CBT) includes many techniques, so as applied relaxation, exposure in vivo, exposing through imagery, panic management, breathing retraining, and cognitive restructuring. Meta-analyses (13-15) support the efficacy of CBT in improving panic symptoms and overall disability. in the greatest degree of the RCTs included in these meta-analyses included eight to 15 sessions of CBT although a not many studies have reported similar efficacy with simply four sessions. (13) Meta-analyses have originate that specialized cognitive therapy, behavior therapy, and combined CBT are superior to general emotionally supportive psychotherapy in patients with panic disorder.
