Evaluation of periodic leg movements and associated transcranial magnetic stimulation parameters in restless legs syndrome.

Restless legs syndrome (RLS), a sensorimotor disorder characterized by unpleasant sensations commonly localized in the legs, is frequently associated with periodic limb movements (PLMs) during sleep. We investigated the role of transcranial magnetic stimulation (TMS) and cortical silent period (CSP) duration as diagnostic and monitoring tools in 20 patients with primary RLS before and after 1 month of treatment and also studied 15 normal age‐ and gender‐matched subjects. Polysomnographic assessment was undertaken and the PLM index determined in 17 of the 20 patients. We also studied the correlation between sleep efficiency index and CSP duration because of the increasing severity of the sleep disturbance and PLMs in patients with RLS. Our results demonstrate that the duration of the CSP was reduced in patients with RLS, and that dopaminergic treatment normalized this duration. There was no correlation between the PLM index and CSP duration. It may be speculated that PLMs and the CSP are due to different inhibitory mechanisms and they may be used separately as diagnostic and monitoring tools in patients with primary RLS.

Polysomnography in patients with post-traumatic stress disorder

Aims:  The purpose of the present study was to investigate sleep structure in post‐traumatic stress disorder (PTSD) patients with and without any psychiatric comorbidities. The relationship between sleep variables and measurements of clinical symptom severity were also investigated.

Prevalence of insomnia symptoms: results from an urban district in Ankara, Turkey

Objective. Characteristics of insomnia symptoms in Turkey are not well established. The goal of this study was to determine the prevalence of insomnia and related symptoms in an urban district of Turkey. Method. The study was carried out in Ankara, in an urban district with a population of 2665. Out of the 1332 people in the sample, 1034 in the 15–65 age range were included in the study. Interviews were conducted according to the “Sleep Disorders Assessment Questionnaire” developed by the researchers. The Insomnia Severity Index (ISI) was also given to the subjects with a sleep problem to measure the subjective quality and quantity of insomnia symptoms. Results and conclusion. A total of 29.4% of all participants reported a sleep problem, out of which 23.7% defined one or more of the insomnia symptoms which included difficulty initiating sleep (DIS), difficulty maintaining sleep (DMS), early morning awakening (EMA), non-restorative sleep (NRS) and sleep deprivation (SD). Insomnia risk was found to be significantly increased with age, female sex, smoking and chronic medical illness. A total of 75.9% of participants who reported insomnia symptoms did not seek medical help for their complaint. According to the ISI, among the subjects with insomnia symptoms, 79 (32.2%) had subthreshold insomnia, 43 (17.6%) had clinical insomnia, 12 (4.9%) had severe clinical insomnia, while 88 (35.9%) did not score in the range indicating insomnia. The findings are discussed in the light of previous research and in relation to sociocultural factors emphasizing the need for public education on sleep disorders as medical conditions.

Treatment of compulsive sexual behaviour with clomipramine and valproic acid

The concepts of compulsive sexual behaviour or sexual addiction and treatment of the disorder have been argued over by many investigators. From a scientific point of view, both concepts are still not well established in psychiatric nomenclature. On the other hand, authors point out that compulsive sexual behaviour, obsessive-compulsive disorder and substance addiction show similarities in symptomatology and response to treatment. In this article, the case of a 21-year-old female exhibiting compulsive sexual behaviour since childhood who was treated with a combination of clomipramine and valproic acid is presented and discussed in the light of the relevant literature.
