BACKGROUND Panic attacks have different clinical characteristics among individuals and countries, characterizing time, place, and symptoms are not clearly predictable OBJECTIVE This study aimed to analyze crucial keywords related to panic disorder and identify various clinical characteristics of panic attacks METHODS We collected 8,728 Twitter posts related to panic disorder from January 1 to December 4, 2020. First, we analyzed crucial and simultaneous emergence keywords related to panic disorder. For this, Term frequency, Term Frequency-Inverse Document Frequency, degree centrality, and N-gram analyses were conducted using Rstudio and TEXTOM and visualized as word clouds. Also, we classfied results of Term frequency for panic disorder into physical symptoms, triggers, time, place, affect, pathology, person, and coping. RESULTS First, depression, drugs, respiration, and stress were keywords related to panic disorder. Next, hyperventilation, palpitations, and shaking were common physical symptoms. Stress, sound, trauma, and coffee were also ranked high in terms of triggering situations. Additionally, in terms of time, morning, night, and dawn accounted for most of the time. Meanwhile, homes, schools, subways, and companies were ranked high as places of occurrence. Regarding affect, fear, tears, and embarrassment were also common. Furthermore, anxiety and depression were ranked high in terms of pathology. Finally, drugs and hospitals were ranked high in terms of coping. CONCLUSIONS These results help to understand the main characteristics of panic disorder and various aspects of unexpected panic attacks and are expected to be a basis for identifying the characteristic clinical aspects of panic disorder among Koreans.

Bigrams and trigrams are commonly used in statistical natural language processing; this paper will describe techniques for working with much longer n-grams. Suffix arrays (Manber and Myers 1990) were first introduced to compute the frequency and location of a substring (n-gram) in a sequence (corpus) of length N. To compute frequencies over all N(N+1)/2 substrings in a corpus, the substrings are grouped into a manageable number of equivalence classes. In this way, a prohibitive computation over substrings is reduced to a manageable computation over classes. This paper presents both the algorithms and the code that were used to compute term frequency (tf) and document frequency (df) for all n-grams in two large corpora, an English corpus of 50 million words of Wall Street Journal and a Japanese corpus of 216 million characters of Mainichi Shimbun. The second half of the paper uses these frequencies to find “interesting” substrings. Lexicographers have been interested in n-grams with high mutual information (MI) where the joint term frequency is higher than what would be expected by chance, assuming that the parts of the n-gram combine independently. Residual inverse document frequency (RIDF) compares document frequency to another model of chance where terms with a particular term frequency are distributed randomly throughout the collection. MI tends to pick out phrases with noncompositional semantics (which often violate the independence assumption) whereas RIDF tends to highlight technical terminology, names, and good keywords for information retrieval (which tend to exhibit nonrandom distributions over documents). The combination of both MI and RIDF is better than either by itself in a Japanese word extraction task.

Objective: Research has accumulated over the past several years demonstrating a relationship between childhood trauma such as sexual abuse and female panic disorder (PD). Most of studies have generally suffered from methodological limitations, including small sample size and not controlling for psychiatric comorbidity and suicidality which can influence the clinical characteristics. This study aimed to investigate differences of demographic and clinical characteristics between female PD patients with (PD+S) and without early sexual abuse history (PD-S). Design and Method: We examined data from 101 patients diagnosed with PD. We divided the patients with PD into PD-S (69 patients) and PD+S (32 patients) to compare demographic (age, marriage, education, suicidality history, comorbidity) and clinical characteristics [coping strategies, Beck Anxiety Inventory (BAI), Beck Depression Inventory (BDI), Panic disorder severity (PDSS), Anxiety Sensitivity Index (ASI), Albany Panic and Phobia Questionnaire (APPQ) - agoraphobia subscale, NEO-neuroticism (NEO-N)]. IBM SPSS version 21.0 was used for statistical analysis. Results: There were no differences between PD+S group and PD–S group with respect to demographics and coping strategies, BAI, BDI, PDSS and ASI. Compared to the PD-S, PD+S group showed higher levels of neuroticism (p=0.00) and agoraphobia (p=0.04). Conclusions: The current study suggests that female PD+S patients can be associated with neuroticism and agoraphobia. Therefore it may be needed to pay attention to the sexual abuse history in female patients with PD.

Currently, panic disorder (PD) is considered a mental disorder based on the assumptions that panic attacks (PAs) are “false alarms” that arise from abnormally sensitive defense systems in the central nervous system and that PD is treated with therapies specifically acting on anxiety or fear mechanisms. This article aims to propose an alternative perspective based on the results of some experimental studies. Our heuristic proposal suggests not only that PD may be a mental disorder but also that patients with PD have real abnormal body functioning, mainly involving cardiorespiratory and balance systems, leading to a decline in global physical fitness. PAs, as well as physical symptoms or discomfort in some environmental situations, may be “real alarms” signaling that the adaptability resources of an organism are insufficient to respond appropriately to some internal or external changes, thus representing the transient conscious awareness of an imbalance in body functioning. The antipanic properties of several modern treatments for PD may include their beneficial effects on body functions. Although anxiety or fear mechanisms are evidently involved in PD, we hypothesize that a reduction of physical fitness is the “primum movens” of PD, while anxiety or fear is induced and sustained by repeated signals of impaired body functioning. We propose considering panic in a broader perspective that offers a central role to the body and to contemplate the possible role of somatic treatments in PD.

Thirteen patients with panic disorder with predominantly cardiorespiratory (CR) symptoms were compared with seven patients with predominantly gastrointestinal (Gl) symptoms in an experimental procedure that involved exposure to phobia talk and voluntary hyperventilation (VHV). The CR patients had not only higher baseline anxiety, but also during phobia talk had a greater fall in pCO2 and reported more respiratory symptoms than the Gl patients. Moreover, the CR group found VHV more unpleasant and more like their panic attacks than the Gl panickers, and reported more physical symptoms after it. These findings suggest that patients with PD are not only heterogeneous with respect to the system to which panic symptoms refer (CR or Gl) but that provoking arousal in one system is more likely to produce distress if that system is the major focus of complaint. These findings, if replicated, would not support the suggestion that panic disorder is a uniform illness.

Therapeutic strategies described as effective for anxiety disorders include behavioral and cognitive-behavioral procedures of exposure and coping of aversive situations. However, considering that the behavioral pattern common in anxiety disorders is the phobic avoidance, the application of these strategies may difficult the adhesion or promote escape and avoidance of the therapeutic process. The Functional Analytic Psychotherapy is an alternative for dealing with these avoidance/escape behaviors and it can promote coping responses. This case report describes an analysis of the therapeutic relationship of a client with Panic Disorder and Agoraphobia. The intervention based on FAP was considered to help dealing with the avoidance behavior in the therapeutic process. Results show the efficacy of the procedures adopted and confirm the possibility of using FAP for improving the effectiveness of the empirically based psychotherapies.

Background: The COVID-19 pandemic is a global health threat and is by far the largest outbreak of atypical pneumonia, since the SARS outbreak in 2003. A range of psychiatric morbidities such as persistent depression, anxiety, panic attacks, delirium and suicidality were observed in the post infectious state across the world. Hence, the aim of the study was to understand the psychological status of the patients affected by COVID during their post-COVID follow-up period and to examine the socio-demographic and clinical factors associated with high psychological morbidity. Materials and Methods: A cross sectional study conducted in the post-COVID follow up clinic, at a tertiary care hospital between the months of August - November 2020, using a semi structured proforma and rating scales such as Patient Health Questionnaire-9 (PHQ-9), Hospital Anxiety and Depression Scale (HADS) and Insomnia Severity Index (ISI) for depression, anxiety and insomnia, respectively. Results: The study results indicate that the prevalence of depression and anxiety among post-COVID-19 patients was 21.9% and 11.9%, respectively. Insomnia was observed among 21.7%Among various sociodemographic and clinical variables examined, it was observed that female gender, patients with ongoing stressors and patients with post-COVID-19 persistent physical symptoms were found to be associated with greater depression and anxiety among the study population. Conclusions: Persistent physical symptoms and ongoing life stressors are found to be associated with depression and anxiety among post-COVID-19 patients. Hence, periodic screening for individuals with persisting physical symptoms and care for the vulnerable population such as those with ongoing stressors will provide a significant advantage in the follow up of the mental health of the patients affected with COVID-19.

OBJECTIVE: To assess the effectiveness of clonazepam, in a fixed dose (2 mg/day), compared with placebo in the treatment of panic disorder patients. METHOD: 24 panic disorder patients with agoraphobia were randomly selected. The diagnosis was obtained using the structured clinical interview for DSM-IV . All twenty-four subjects were randomly assigned to either treatment with clonazepam (2 mg/day) or placebo, during 6 weeks. Efficacy assessments included: change from baseline in the number of panic attacks; CGI scores for panic disorder; Hamilton rating scale for anxiety; and panic associated symptoms scale. RESULTS: At the therapeutic endpoint, only one of 9 placebo patients (11.1%) were free of panic attacks, compared with 8 of 13 (61.5%) clonazepam patients (Fisher exact test; p=0,031). CONCLUSION: the results provide evidence for the efficacy of clonazepam in panic disorder patients.

Background: COVID-19 is a newly emerging infectious disease which is found to be caused by SARS-2. COVID-19 pandemic has spread worldwide causing a rapidly increasing number of mental disorders cases, primarily anxiety disorder. Since majority of panic disorder patients are present with great anxiety in response to their physical or respiratory symptoms, support and encouragement from psychiatrist or therapist are fundamental to alleviate the severity of the symptoms. Case Report: We reported a case of COVID-19 induced panic disorder in a woman, 52 years old, batak tribe who started to experience multiple panic attacks since one of her family members was confirmed to be Covid-10 positive. Conclusion: In general, panic disorder is a common diagnosis, but this case appeared to be interesting as it is induced by COVID-19 pandemic. As in this case, the individual who experienced multiple panic attack is not even a COVID-19 patient but has one of her family member affected by the virus. A wide body of evidence has shown that this pandemic massively contributes to worsening of psychosocial burden in nationwide.
