“…8,[14][15][16][17] It has also been suggested that neurobiological abnormalities in regions such as the medial prefrontal cortex, brainstem and limbic system (including the temporal lobe, amygdala and hippocampus) mediate PD. 14,[18][19][20] This is in line with the current understanding of the neurocircuitry of fear, in which the amygdala facilitates the processing of sensory input from the cortex to efferent target organs. 14 The role of neurochemical and molecular derangements in these pathways is also increasingly understood.…”

Panic disorder (PD) is an anxiety disorder that affects many South Africans. If undiagnosed or mismanaged, this condition may impact profoundly on an individual's functioning and quality of life. At the primary level, the assessment of panic attacks requires consideration of a number of differential diagnoses. General practitioners also play an invaluable role in the acute and long-term care and appropriate referral of individuals with PD. This article provides an overview of PD in general practice and includes a guideline for case identification and therapeutic options.

“…This contrasts with the findings of Dantendorfer et al (5), and may reflect our use of a quantitative rather than qualitative method of assessment (2). It may also be related to differences in the respective patient populations studied; for example, all the patients with a CSP in the study by Dantendorfer et al (5) had EEG abnormalities. It is also possible that our results could be explained by our relatively small sample size.…”

Panic disorder is thought to involve dysfunction in the septohippocampal system, and the presence of a cavum septum pellucidum might indicate the aberrant development of this system. We compared the prevalence and size of cavum septum pellucidum in 21 patients with panic disorder and in 21 healthy controls by magnetic resonance imaging. The length of the cavum septum pellucidum was measured by counting the number of consecutive 1-mm coronal slices in which it appeared. A cavum septum pellucidum of >6 mm in length was rated as large. There was no significant difference in the proportion of patients (16 of 21 or 76.2%) and controls (18 of 21 or 85.7%) with a cavum septum pellucidum (P = 0.35, Fisher's exact test, one-tailed), and no members of either group had a large cavum septum pellucidum. The mean cavum septum pellucidum rating in the patient and control groups was 1.81 (SD = 1.50) and 2.09 (SD = 1.51), respectively. There were also no significant differences between groups when we analyzed cavum septum pellucidum ratings as a continuous variable (U = 196.5; P = 0.54). Across all subjects there was a trend towards a higher prevalence of cavum septum pellucidum in males (100%, 10 of 10) than females (75%, 24 of 32; P = 0.09, Fisher's exact test, one-tailed). Thus, we conclude that, while panic disorder may involve septohippocampal dysfunction, it is not associated with an increased prevalence or size of the cavum septum pellucidum. Correspondence

“…These training protocols consisted of amplitude uptraining and/or downtraining of selected frequency bands based on qEEG findings. Protocol selections were based on current research and reflect markers found to be associated with anxiety issues (Dantendorfer et al, 1996;Demerdzieva & Pop-Jordanova, 2011;Gold, Fachner, & Erkkilä, 2013;Gunkelman, 2006;Gurnee, 2000;Heller, Nitschke, Etienne, & Miller, 1997;Johnstone, Gunkelman, & Lunt, 2005;Machleidt, Gutjahr, Muegge, & Hinrich, 1985;Price & Budzynski, 2009;Savostyanov et al, 2009;Siciliani, Schiavon, & Tansella, 1975;Stern, 2005, p. 196;Tharawadeepimuk & Wongsawat, 2014;Walker, 2009 Note.

Introduction: Anxiety disorders affect approximately 40 million Americans ages 18 and over (NIMH, 2015). Although qualitative and small-scale quantitative neurofeedback (NF) studies show reduction in anxiety symptoms, large-scale studies and quantitative electroencephalogram (qEEG) driven protocols are non-existent. This retrospective pilot study intended to assess whether qEEG guided amplitude NF is viable in symptom reduction of anxiety. Methods: Nineteen clients were assessed for anxiety, 14 were included in the data. Demographics include age ranges from 11-61 (M = 31.71, SD = 16.33), 9 male and 5 female; six identified as Caucasian, five as Hispanic/Latino, and three Caucasian/Hispanic ethnicity. Pre-and post-assessments included the Zung Self-Rating Anxiety Scale, Screen for Child Anxiety Related Disorders (SCARED), and the Achenbach System of Empirically Based Assessment (ASEBA). Clients received 30-min qEEG guided NF treatment sessions, twice a week. The range of attended session was 7-28 (M = 12.93, SD = 6.32). Results: Enhancement in clients' well-being was evidenced by statistically significant improvement in symptom measures scores. Although improvements for the two most anxiety-related categories on the ASEBA were not significant, other anxiety-related categories did show significant improvement. Yet, qEEG findings were not statistically significant. Directions for future research are discussed.
