Seizure threshold manipulation in electroconvulsive therapy via repetitive transcranial magnetic stimulation. A novel way of augmentation?

INTRODUCTION: A high seizure threshold (ST) is an impeding factor in certain patients, potentially preventing a successful electroconvulsive therapy (ECT) treatment. Several pharmacological and non-pharmacological methods have been put forward to augment ECT in such patients, however, to this date, only a handful of case reports existed about the potential role of repetitive transcranial magnetic stimulation (rTMS), as an augmentation method. OBJECTIVES: and Methods: In this randomized, double-blinded, sham controlled study, we set out to test the hypothesis of whether the application of high frequency transcranial magnetic stimulation (HF rTMS) lowers the seizure threshold for electroconvulsive therapy and whether it has an effect on other aspects of ECT treatment, such as seizure duration (SD), efficacy and safety. RESULTS: 46 patients treated for a major depressive episode, indicated for ECT, were recruited to this study. A significantly lower seizure threshold was observed in the experimental group during ECT titration, on average a decrease by 34.55%, from 34.23 mC to 22.4 mC, p < 0.001 (Wilcox test). We had not observed a significant effect of TMS stimulation before ECT on seizure duration or clinical outcome. Another potentially important observation of this study is that 4 patients in the experimental group developed transient symptoms of hypomania/mania, all of which were stabilized after the combined stimulation protocol was halted spontaneously within a week, without the need to administer mood stabilizers. CONCLUSION: It is likely that HF rTMS stimulation prior to ECT is a novel and simple way of reducing the ST, which is useful in certain groups of patients undergoing this important treatment modality.

Lowering the seizure threshold in electroconvulsive therapy using transcranial magnetic stimulation: A case report.

We demonstrate the feasibility of lowering the seizure threshold using a combined approach of electroconvulsive therapy and transcranial magnetic stimulation. High-frequency transcranial magnetic stimulation of the supplementary motor area shortly before each electroconvulsive treatment session resulted in a reduction of the seizure threshold by half in a male patient with a severe psychotic depressive episode of bipolar affective disorder.

Transient aphasia after right-unilateral ultrabrief electroconvulsive therapy: A case report.

A brief period of aphasia is an extremely rare and likely underreported adverse effect of electroconvulsive therapy. Clinical studies that have described this phenomenon are scarce and its prevalence is unknown. We present a unique case of a 35-year old woman, who underwent an outpatient ECT session at our department, followed by a short span of aphasic symptoms, the extent of which were monitored clinically and via the czech version of the Minnesota aphasia screening test.

Gut, Microbiome, and Brain Regulatory Axis: Relevance to Neurodegenerative and Psychiatric Disorders.

It has become apparent that the molecular and biochemical integrity of interactive families, genera, and species of human gut microflora is critically linked to maintaining complex metabolic and behavioral processes mediated by peripheral organ systems and central nervous system neuronal groupings. Relatively recent studies have established intrinsic ratios of enterotypes contained within the human microbiome across demographic subpopulations and have empirically linked significant alterations in the expression of bacterial enterotypes with the initiation and persistence of several major metabolic and psychiatric disorders. Accordingly, the goal of our review is to highlight potential thematic/functional linkages of pathophysiological alterations in gut microbiota and bidirectional gut-brain signaling pathways with special emphasis on the potential roles of gut dysbiosis on the pathophysiology of psychiatric illnesses. We provide critical discussion of putative thematic linkages of Parkinson's disease (PD) data sets to similar pathophysiological events as potential causative factors in the development and persistence of diverse psychiatric illnesses. Finally, we include a concise review of preclinical paradigms that involve immunologically-induced GI deficits and dysbiosis of maternal microflora that are functionally linked to impaired neurodevelopmental processes leading to affective behavioral syndromes in the offspring.

ADHD and Present Hedonism: time perspective as a potential diagnostic and therapeutic tool.

The article draws primarily from the behavioral findings (mainly psychiatric and psychological observations) and points out the important relationships between attention-deficit/hyperactivity disorder (ADHD) symptoms and time orientation. Specifically, the authors argue that there is a significant overlap between the symptoms of ADHD and Present Hedonism. Present Hedonism is defined by Zimbardo's time perspective theory and assessed by Zimbardo Time Perspective Inventory. Developmental data on Present Hedonism of males and females in the Czech population sample (N=2201) are also presented. The hypothesis of relationship between ADHD and Present Hedonism is mainly derived from the prevalence of addictive behavior (mainly excessive Internet use, alcohol abuse, craving for sweets, fatty foods, and fast foods), deficits in social learning, and increased aggressiveness both in ADHD and in the population scoring high on Present Hedonism in the Zimbardo Time Perspective Inventory. We conclude that Zimbardo's time perspective offers both: 1) a potential diagnostic tool - the Zimbardo Time Perspective Inventory, particularly its Present Hedonism scale, and 2) a promising preventive and/or therapeutic approach by the Time Perspective Therapy. Time Perspective Therapy has so far been used mainly to treat past negative trauma (most notably, posttraumatic stress disorder); however, it also has value as a potential therapeutic tool for possible behavioral compensation of ADHD.

Statin-induced changes in mitochondrial respiration in blood platelets in rats and human with dyslipidemia.

3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) are widely used drugs for lowering blood lipid levels and preventing cardiovascular diseases. However, statins can have serious adverse effects, which may be related to development of mitochondrial dysfunctions. The aim of study was to demonstrate the in vivo effect of high and therapeutic doses of statins on mitochondrial respiration in blood platelets. Model approach was used in the study. Simvastatin was administered to rats at a high dose for 4 weeks. Humans were treated with therapeutic doses of rosuvastatin or atorvastatin for 6 weeks. Platelet mitochondrial respiration was measured using high-resolution respirometry. In rats, a significantly lower physiological respiratory rate was found in intact platelets of simvastatin-treated rats compared to controls. In humans, no significant changes in mitochondrial respiration were detected in intact platelets; however, decreased complex I-linked respiration was observed after statin treatment in permeabilized platelets. We propose that the small in vivo effect of statins on platelet energy metabolism can be attributed to drug effects on complex I of the electron transport system. Both intact and permeabilized platelets can be used as a readily available biological model to study changes in cellular energy metabolism in patients treated with statins.

Patient characteristics and symptoms associated with perceived coercion during hospital treatment.

OBJECTIVE: Large numbers of psychiatric patients either are involuntarily admitted to hospital treatment or feel coerced despite a legally voluntary admission. For ethical and clinical reasons, their perceived coercion should be reduced as far as possible. There is however limited evidence on patient characteristics associated with perceived coercion during hospital treatment. This study aimed to identify i) sociodemographic and clinical characteristics associated with perceived coercion at admission and ii) changes in symptoms and global functioning associated with changes in perceived coercion over time. METHOD: Three thousand and ninety three in-patients who were involuntarily admitted or felt coerced to hospital treatment despite a legally voluntary admission were recruited in the European evaluation of coercion in psychiatry and harmonization of best clinical practice - EUNOMIA project in 11 European countries. Perceived coercion, global functioning and symptoms were assessed after admission and at a 3-month follow-up. RESULTS: Involuntary admission, female gender, poorer global functioning and more positive symptoms were associated with higher levels of perceived coercion at admission. Perceived coercion significantly decreased over time, and the improvements in global functioning and positive symptoms were associated with reduction in perceived coercion. CONCLUSION: Female patients perceive more coercion in psychiatric hospital treatment. Effective treatment for positive symptoms and improving patients' global functioning may lead to a reduction in perceived coercion.

How to improve clinical practice on involuntary hospital admissions of psychiatric patients: suggestions from the EUNOMIA study.

Number and procedures of involuntary hospital admissions vary in Europe according to the different socio-cultural contexts. The European Commission has funded the EUNOMIA study in 12 European countries in order to develop European recommendations for good clinical practice in involuntary hospital admissions. The recommendations have been developed with the direct and active involvement of national leaders and key professionals, who worked out national recommendations, subsequently summarized into a European document, through the use of specific categories. The need for standardizing the involuntary hospital admission has been highlighted by all centers. In the final recommendations, it has been stressed the need to: providing information to patients about the reasons for hospitalization and its presumable duration; protecting patients' rights during hospitalization; encouraging the involvement of family members; improving the communication between community and hospital teams; organizing meetings, seminars and focus-groups with users; developing training courses for involved professionals on the management of aggressive behaviors, clinical aspects of major mental disorders, the legal and administrative aspects of involuntary hospital admissions, on communication skills. The results showed the huge variation of involuntary hospital admissions in Europe and the importance of developing guidelines on this procedure.

Patients' subjective initial response and the outcome of inpatient and day hospital treatment.

OBJECTIVE: This study aimed to establish whether psychiatric patients' subjective initial response (SIR) to hospital and day hospital treatment predicts outcomes over a one-year follow-up period. METHOD: We analysed data from 765 patients who were randomised to acute psychiatric treatment in a hospital or day hospital. SIR was assessed on day 3 after admission. Outcomes were psychiatric symptom levels and social disability at discharge, and at 3 and 12 months after discharge. RESULTS: After controlling for socio-demographic and clinical characteristics, a more positive SIR was significantly associated with lower symptom levels at discharge and 3 months after discharge and lower social disability at 3 months and 12 months after discharge. CONCLUSION: SIR can predict outcomes of complex interventions over a one-year period. Patients' initial views of acute hospital and day treatment should be elicited and considered as important.

Premenstrual dysphoric disorder--review of actual findings about mental disorders related to menstrual cycle and possibilities of their therapy.

It is known that mood disorders in women explicitly relates to estrogen production. Except for these findings phenomenon as Premenstrual Syndrome and Premenstrual Dysphoric Disorder, directly connected to menstrual cycle in women, is widely discussed. Premenstrual dysphoric disorder (PMDD) is a set of subjectively unpleasant mental and somatic symptoms. It appears in luteal phase of ovarian cycle. During menstruation it remits and disappears up to one week from its termination. DSM IV classified PMDD into the category of "Other specific depressive disorders" and further revision DSM IV-TR classifies PMDD as a separate strictly defined psychiatric diagnosis. The International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10) does not include any specific category as PMDD or similar. The closest category F38.8 does not represent the core of the phenomenon because it relates only to general depressive symptomatology and does not give specific diagnostic criteria to menstrual cycle related mood disorders (Grady-Weliky, 2003). In the presented article, possible effectivity of PMDD treatment with the focus to antidepressants of SSRI type (Serotonin selective reuptake inhibitors) is discussed. In spite of interesting and significant findings, the treatment of PMDD and accordingly PMS is above all multidisciplinary question and it must be treated like that.

An increase in substance misuse rather than other mental disorders has led to increased forensic treatment rates in the Czech Republic.

It is suggested that limited access to appropriate care forces psychiatric patients towards forensic treatment or to the prison system. According to our data, the number of prisoners, the number of hospitalized psychiatric patients (from 1987 to 2007), the number of court ordered forensic treatments in the Czech Republic (from 1991 to 2007), and the rate of people in psychiatric and sex offender forensic treatment has remained constant. However, an increase (162%) in number of treatments imposed for abusing illicit drugs did occur during this period. This increase contributed to the correlation between both the number of sentences given for protective treatment and the number of all sentenced persons (Pearson cor. 0.647, p < 0,001) and the number of prisoners (Pearson cor. 0.798, p < 0,001). The analysis of all admissions to a forensic facility from a catchment area of 1,260,318 inhabitants shows no increase in number of admission between 2002 and 2007. The same data prove that the number of patients ordered to psychiatric and sexology treatment remained steady and did not reflect changes in the number of prisoners or number of hospitalized patients. This could be explained by a high number of psychiatric hospitalizations protecting the patients from deteriorating to criminal behaviour.

Imprisonment and its influence on psychobiological needs.

This article presents results of two research studies which focus on the analyses of specific needs associated with members of a delinquent subculture and the psychological alterations which occur as a result of adaptation to their imprisonment. In the first case, the specificity and differences in the area of needs were determined by content analysis of prison correspondence and further by means of an analysis of content association as reactions to a complex of incomplete sentences. The differences have been ascertained by virtue of factors that are considered significant from the point of view of delinquency and potential recidivism. A great deal of attention is focussed on prisonisation as a specific adaptation to imprisonment and its influence on the dissimilarity in the structure of the needs of those prisoners investigated. The results of both investigations facilitate mutual comparison. They also partially refer to the discriminating capability of the applied methods. The findings and results are applicable in penitentiary practice and are significant for the practical application by psychologists and other specialists in their work with offenders.

Social disability in different mental disorders.

OBJECTIVE: To assess the social disability of people with different psychiatric disorders. METHODS: Cross-site survey in five psychiatric hospitals (Dresden, Wroclaw, London, Michalovce and Prague). Working-aged patients diagnosed (ICD-10) with schizophrenia and related disorders (F2), affective disorders (F3), anxiety disorders (F4), eating disorders (F5) and personality disorders (F6), were assessed at admission (n=969) and 3 months after discharge (n=753) using the Brief Psychiatric Rating Scale and the Groningen Social Disability Schedule. The main outcome measure was Interviewer-rated social disability. RESULTS: During acute episodes patients with personality, eating and schizophrenic disorders functioned less effectively than those with affective or anxiety disorders. After controlling for age and severity of psychopathology, there was no significant effect of the diagnosis (during remission), sex, education and history of disorder on disability. Site, employment and partnership were significant factors for the level of social disability in both measure points. CONCLUSION: Severity of psychopathological symptoms, not the diagnosis of a mental disorder, was the most significant factor in determining the level of social functioning, particularly during the remission period. Site, employment and partnership appeared as significant factors influencing the level of social disability.

Limbic irritability and chaotic neural response during conflicting stroop task in the patients with unipolar depression.

According to recent findings activation of anterior cingulate cortex (ACC) is related to detecting cognitive conflict. This conflict related activation elicits autonomic responses which can be assessed by psychophysiological measures such as heart rate variability calculated as beat to beat R-R intervals (RRI). Recent findings in neuroscience also suggest that cognitive conflict is related to specific nonlinear chaotic changes of the signal generated by neural systems. The present study used Stroop word-color test as an experimental approach to psychophysiological study of cognitive conflict in connection with RRI measurement, psychometric measurement of limbic irritability (LSCL-33), depression (BDI-II) and calculation of largest Lyapunov exponents in nonlinear data analysis of RRI time series. Significant correlation 0.61 between largest Lyapunov exponents and LSCL-33 found in this study indicate that a defect of neural inhibition during conflicting Stroop task is closely related to limbic irritability. Because limbic irritability is probably closely related to epileptiform abnormalities in the temporolimbic structures, this result might represent useful instrument for indication of anticonvulsant treatment in depressive patients who are resistant to antidepressant medication.

[Brain diseases and modern-day society]. / Nemoci mozku a soucasná spolecnost.

Brain diseases represent one of the largest strains in the developed societies of the modem world. The major lost is in the indirect expenses caused by psychical disorders. Psychiatric diseases start frequently in childhood, affect from the life lasting view one half of the population and frequently result in disablement. Administrative of the World Health Organization and of European Union consider these problems highly important and require emancipation of psychically disabled, including the financial support for the care. Only 4% of the National Budget is directed to that sector in Czech Republic, which is the second lowest share (after Slovakia).

[Recommendations for the treatment of tobacco dependence]. / Doporucení pro lécbu závislosti na tabáku.

This first Czech version of guidelines formulated by the working group of mentioned medical associations is based on current literature and international guidelines. They are aimed mainly on clinical medicine and on incorporation of this treatment into the health care system according to WHO recommendations. They should serve to the treatment of tobacco dependence at any level: during any contact with the smoking patient (short intervention), in specialised centres or for the health care providers or health system itself.

Mental health care in Prague.

AIM: To describe principles and characteristics of mental health care in Prague. METHOD: Based on existing data, service provision, number of professionals working in services, funding arrangements, pathways into care, user/carer involvement and specific issues are reported. RESULTS: Mental health care in Prague has a special position in the Czech Republic. Prague has the longest tradition of psychiatric treatment including the German Psychiatric Department of the Charles University. The density of services is higher, there are more extrainstitutional facilities and acute beds are located in general hospitals. DISCUSSION: Whilst various issues of mental health care in Prague overlap with those in other European capitals, there also are some specific problems and features. After substantial political changes in early 90s, the prevailing institutional model of psychiatric care has started to be changed according to the Concept of Psychiatric Care prepared by the Czech Psychiatric Association and approved by the Ministry of Health. However, stigma connected with mental disturbances is still present and there are not enough financial resources and will to put these plans rapidly into the practice.

Key moments in the history of czech psychiatry.

1783 - The Austrian Emperor Joseph II. established a department for mentally ill priests in the hospital of the Merciful Brothers in Prague. 1790 - Based on the Emperors decision, a new hospital was opened in Prague. A new two-storey building was used exclusively for treatment of the mentally ill patients. 1821 - Lectures about insanity were opened at Prague University. 1844 - A New house (nowadays a psychiatric University department) was established.
