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.

The therapeutic effect of cognitive-behavioral therapy(CBT) for panic disorder and agoraphobia (PD/PDA) has been supported by evidences from the several studies. We the have experienced good results of CBT for more than 50 patients with PD/PDA for last two years. In spite of the powerful therapeutic effect, CBT has not been utilized well by psychiatrists in this country. We described the cognitive conceptualization of panic and agoraphobia, fiequently used assessments and homeworks in CBT for PD/PDA, and detailed concepts and methods of the each component of CBT based on our experience. Also, we discussed the comparative studies of the therapeutic results and factors that could influence the effect of CBT for PD/PDA.

OBJECTIVES: It is increasingly thought that the human cerebellum plays an important role in emotion and cognition. Although recent evidence suggests that the cerebellum may also be implicated in fear learning, only a limited number of studies have investigated the cerebellar abnormalities in panic disorder. The aim of this study was to evaluate the cerebellar gray matter deficits and their clinical correlations among patients with panic disorder. METHODS: Using a voxel-based morphometry approach with a high-resolution spatially unbiased infratentorial template, regional cerebellar gray matter density was compared between 23 patients with panic disorder and 33 healthy individuals. RESULTS: The gray matter density in the right posterior-superior (lobule Crus I) and left posterior-inferior (lobules Crus II, VIIb, VIIIa) cerebellum was significantly reduced in the panic disorder group compared to healthy individuals (p < 0.05, false discovery rate corrected, extent threshold = 100 voxels). Additionally, the gray matter reduction in the left posterior-inferior cerebellum (lobule VIIIa) was significantly associated with greater panic symptom severity (r = -0.55, p = 0.007). CONCLUSIONS: Our findings suggest that the gray matter deficits in the posterior cerebellum may be involved in the pathogenesis of panic disorder. Further studies are needed to provide a comprehensive understanding of the cerebro-cerebellar network in panic disorder.

OBJECTIVES: Anxiety sensitivity (AS) is the fear of anxiety-related sensations based on beliefs about their harmful consequences. Despite its status as the most popular measure of AS, the anxiety sensitivity index is too abbreviated to adequately measure the somatic, cognitive, and social factor. The Anxiety Sensitivity Index-Revised (ASI-R) is a revised and expanded version of the ASI that was developed to improve the assessment of AS and its dimensions. The present study was conducted to determine the validity and reliability of the Expanded Anxiety Sensitivity Index. METHODS: Five hundred sixty six community samples and 77 patients with panic disorders were enrolled in this study. All subjects completed a psychometric assessment package which included the Anxiety Sensitivity Index (ASI), ASI-R, Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI) and State-Trait Anxiety Inventory-Trait (STAI-T). RESULTS: 1) ASI-R showed good internal consistency (Cronbach's alpha=.93). 2) ASI-R demonstrated high test-retest reliabilities (r=.82). 3) Moderate correlations were observed among ASI-R, BDI (r=.50), STAI-T (r=.41), and BAI (r=.67). 4) An exploratory factor analysis revealed four ASI-R factors. 5) Panic patients had significantly higher ASI-R scores than the community samples (t=7.787, p<.01). CONCLUSION: We found that ASI-R and its subscales had valuable internal consistency, test-retest reliability, and convergent and construct validity. These results suggest that ASI-R is a reliable and valid measuring tool of anxiety sensitivity.

OBJECTIVE: In the present study, we measured hippocampal N-acetyl-l-aspartate (NAA), choline (CHO) and creatine (CRE) values in patients with panic disorder and healthy control subjects using in vivo 1H MRS. METHODS: We scanned 20 patients meeting Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) criteria for panic disorder and 20 matched healthy controls with a 1.5 Tesla GE Signa Imaging System and measured of NAA, CHO, and CRE in hippocampal regions. RESULTS: When NAA, CHO and CRE values were compared between groups, statistically significant lower levels for all ones were detected for both sides. CONCLUSION: Consequently, in the present study we found that NAA, CHO and CRE values of the patients with panic disorder were lower than those healthy controls. Future studies involving a large number of panic patients may shed further light on the generalizability of the current findings to persons with panic disorder.

OBJECTIVE: Panic disorder is characterized by recurrent panic attacks, persistent concerns about additional attacks, and worry about the implications of the attack or significant changes in behavior related to the attacks. We examined the efficacy of 24-week naturalistic, open-label escitalopram treatment in terms of the response and remission rates and functional disability in 119 adult Korean patients with panic disorder from 6 clinical centers in South Korea. METHODS: Clinical severity and functional impairment were assessed at baseline and at 4, 12, and 24 weeks after the treatment using the Panic Disorder Severity Scale and Sheehan Disability Scale. Ninety-six patients (80.7%) showed a treatment response, and 87 patients (73.1%) had attained remission after 24 weeks of escitalopram treatment. RESULTS: Continuous improvement in the Panic Disorder Severity Scale and Sheehan Disability Scale scores was found over the 24 weeks of treatment. CONCLUSION: These findings suggest that escitalopram treatment is very effective for panic disorder in terms of both response and remission rates and that long-term pharmacotherapy with escitalopram continuously improved panic symptoms and functional disability in Korean patients with panic disorder.
