Sleep disturbance is a one of common complaints among patients with panic disorder. However, clinicians and researchers did not give much attention to the sleep symptoms of panic disorder yet. Several previous studies suggested that the sleep disturbance in panic disorder is mediated by nocturnal panic attack. In terms of the pathophysiology of panic disorder, nocturnal panic attack seems to be closely associated with the sleep problems in panic disorder. In this article, the authors reviewed various previous studies about sleep of panic disorder and intended to give importance of evaluating sleep disturbances and nocturnal panic attack in panic disorder for both clinical and research purpose.

Panic disorder is a relatively common psychiatric illness (life time prevalence 3.5%), and it is known that 91% of patients with panic disorder have at least one other psychiatric disorder. And patients with panic disorder, who have coexisting generalized anxiety disorder, tend to have more severe symptoms and less favorable outcome and respond less well to psychological and pharmacologic treatment. The authors report a 51-year old male who was previously diagnosed as panic disorder in the out-patient clinic, showed poor response to antipanic treatment. However, he showed great improvement after he was treated for panic disorder and comorbid generalized anxiety disorder. This case report showed that more effort to identify comorbid conditions is needed in panic disorder patients and the effectiveness of venlafaxine in the treatment of panic disorder with generalized anxiety disorder.

Objectives:This study was performed to investigate the differences of the clinical feature between panic disorder with agoraphobic patients and panic disorder without agoraphobic patients. Methods:Two hundred nine patients meeting the criteria of DSM-IV panic disorder were recruited. One group was panic disorder with agoraphobia(n=78, 42 male(53.8%), mean age $37.6{\pm}9.9$ years), another was panic disorder without agoraphobia(n=131, 81 male(61.8%), mean age $40.5{\pm}10.3$ years). The numbers and frequency of panic symptoms were compared between two groups with t-test, and the logistic regression analysis were used for predicting panic disorder with agoraphobia. Results:The number of panic symptoms during panic attack was significantly higher in the group of panic disorder with agoraphobia than the group of panic disorder without agoraphobia(p<0.05).'Sweating','nausea or abdominal distress','fear of losing control of going crazy','chills or hot flushes'were more frequent in the group of panic disorder with agoraphobia(p<0.05). Among panic symptoms on logistic regression analysis,'sweating',' nausea or abdominal distress','fear of losing control or going crazy'turned out to correlate significantly with risk of development of agoraphobia in panic disorder. Conclusion:These results suggest that the frequency of some symptoms during panic attack may be a predictor of agoraphobia in patients with panic disorder.

Panic disorder is a common psychiatric illness that causes considerable morbidity. However, the biological basis of panic disorder remains unclear. In this report, we present and summarize the current literature on functional neuroimaging studies related to the neurobiology of panic disorder. The findings were summarized and divided into six groups : (1) known brain structures related to anxiety, especially panic disorder ; (2) structural results ; (3) functional imaging studies at rest ; (4) functional imaging studies with challenge testing ; (5) neuroreceptor studies ; and (6) changes in the treatment of panic disorder. Based on the findings of these neuroimaging studies, it seems as though panic disorder involves the hippocampal and parahippocampal areas, including the amygdala, as well as some cortical regions, such as the temporal and prefrontal cortices. Panic disorder is known to be associated with an imbalance between the right and left hemispheres of the brain at rest or during panic attacks. During a panic attack, patients with panic disorder are likely to experience an increase in local activity in the cingulate, insula, midbrain, and so on. On the other hand, a widespread reduction in the cortical areas has also been reported in most provocation studies. Thus, panic disorder may be related to the excess activation of the fear networks in response to subtle environmental cues and insufficient inhibition from higher cortical control areas ; however ; further studies are recommended in order to fully understand the neurobiology of panic disorder.

We extract the symptom of panic disorder from the context awareness environment. It extracts body context information through natural movement that exists in everyday life and uses a component of panic disorder. The ontology theory can be used to provide information on the degree of symptoms of panic disorder through inference process. For the components of panic disorder to the information processing based on ontology are defined as Classes. Panic disorder index is expressed through ontology modeling so that the condition of panic disorder can be known. The derivation of panic disorder component and panic disorder index will enable context awareness based information service for panic disorder. The context information is periodically synchronized with the context awareness on based device. Panic disorder can be used to improve the lifestyle of panic disorder.

Objectives The principal aim of the present study was to investigate the characteristic depressive symptoms in patients with social anxiety disorder (SAD) and panic disorder in comparison to patients with depressive disorder. Methods This study included 132 patients with SAD, 128 panic disorder and 64 depressive disorder (major depressive disorder, dysthymia etc.) patients without comorbid psychiatric disorders. The Beck Depressive Inventory (BDI) is used to measure depressive symptoms. We divided BDI into three categories originally described by Shafer AB, including negative attitude toward self, performance impairment, and somatic symptoms. We compared the depressive symptoms of SAD, panic disorder and depressive disorder by using ANOVA. Results Negative attitude toward self was noticeable in SAD (SAD $0.54{\pm}0.23$, panic disorder $0.41{\pm}0.17$, depressive disorder $0.46{\pm}0.11$, p < 0.001). Performance impairment and somatic symptoms were remarkable in panic disorder than in SAD and depressive disorder (performance impairment : SAD $0.39{\pm}0.21$, panic disorder $0.44{\pm}0.14$, depressive disorder $0.40{\pm}0.09$, p = 0.009 ; somatic symptoms : SAD $0.07{\pm}0.10$, panic disorder $0.15{\pm}0.12$, depressive disorder $0.14{\pm}0.08$, p < 0.001). Conclusions The results facilitate an approach to optimal treatment for patients with comorbidity of anxiety disorder and depression.

Objective : Panic disorders are frequently accompanied by major depressive disorder (MDD). There is insufficient information about which clinical factors in panic disorder are associated with comorbid MDD. The aim of this study is to identify clinical factors related with comorbid MDD in patients with panic disorder. Methods : Two experienced psychiatrists diagnosed panic disorder based on DSM-IV criteria. This diagnosis in the 275 subjects was confirmed again by Mini-International Neuropsychiatric Interview (MINI). Lifetime comorbid psychiatric diagnoses were examined by MINI. The Hamilton Depression Scale (HAMD), Hamilton Anxiety Scale (HAMA) and Panic Disorder Severity Scale (PDSS) were used to assess the severity of depressive, anxiety and panic symptoms. Results : The result of MINI showed that 95 patients (34%) with panic disorder satisfied the diagnosis of MDD. Multivariate logistic regression model showed that comorbid generalized anxiety disorder (GAD) and the symptom of "fear of losing control or going crazy" were associated with MDD in patients with panic disorder. In female patients, the "chills or hot flushes" symptom was also associated with comorbid MDD. Conclusion : These results showed that coexisting GAD and certain symptoms of panic are associated with comorbid MDD.

Objectives We investigated whether the catechol-O-methyltransferase (COMT) and serotonin related gene polymorphisms may be associated with agoraphobia in patients with panic disorder in Korea. Methods The COMT gene (rs4680), 5-hydroxytryptamine (serotonin) transporter linked polymorphic region (5-HTTLPR) gene (rs25531), serotonin receptor 1A (HTR1A) gene (rs6295) genotypes were analyzed in 406 patients with panic disorder and age-sex matched 206 healthy controls. Patients with panic disorder were dichotomized by the presence of agoraphobia. The following instruments were applied : the Beck Depression Inventory, the Beck Anxiety Inventory, the Panic Disorder Severity Scale. Results There was a significant difference in the distribution of 5-HTTLPR genotype between panic patients with agoraphobia and without agoraphobia (p = 0.024). That is, the panic patients with agoraphobia had a significant excess of the less active 5-HTTLPR allele (S allele). (p = 0.039) Also, we replicated previous western reports which indicated a significant difference in the distribution of COMT genotype between the patients with panic disorder and the healthy controls (p = 0.040). However, no significant associations of agora-phobia or panic disorder with HTR1A gene polymorphisms were found. Conclusions This result supports that the COMT polymorphisms may be associated with panic disorder and suggests that the 5-HTTLPR polymorphisms may play a role in the pathogenesis of agoraphobia in the Korean patients with panic disorder.
