[Changes in sleep patterns and the doom-scrolling (doom-surfing) phenomenon as modifiable risk factors for anxiety due to continuous stress of the COVID-19 pandemic]. / Izmeneniya rezhima sna i potreblenie informatsii s negativnym kontentom v internete («dumskrolling¼, «dumserfing¼) kak upravlyaemye faktory riska razvitiya trevogi v usloviyakh stressa pandemii COVID-19.

OBJECTIVE: To evaluate the modifiable daily behavior patterns associated with increased anxiety indicators in the general population in response to the COVID-19 pandemic. MATERIAL AND METHODS: The study examined the characteristics of the Russian population (n=7777) of the international multicenter project COMET-G. In particular, variables were targeted to describe deviations in the behavior of adults during the period of application of measures of social isolation in connection with the pandemic, and revealing a relationship with the total score on the Spielberger State Anxiety Scale (STAI-S). Among these variables, experts selected those that could potentially be subject to change in the short term, that is, act as manageable or modifiable risk factors for the development of anxiety. The selected variables were analyzed in a statistical PLS-model to identify indicators that make the most significant contribution to the increase in the total anxiety score. RESULTS: Our statistical model explained 48.4% of the variability in the STAI-S anxiety total scores related to changes in daily life habits. In particular, doom-scrolling/doom-surfing about the spread of the virus and the COVID-19 pandemic, changes in sleep patterns and usual daily life activities due to social isolation measures presented as factors significantly contributing to the increase of state anxiety. CONCLUSION: Given the manageable or modifiable risk factors that we have identified, public awareness and therapeutic recommendations, pointing to the need to (I) control the amount of time spent in the internet and monitor their internet-based content consumption, (II) regulate sleep-wake patterns, (III) maintain daily habits and household activities, may reduce the likelihood of developing anxiety disorders in the context of the impact of a global chronic stress due to the COVID-19 pandemic and associated social isolation measures.

Sociodemographic Factors of Depression During the COVID-19 Pandemic in Malaysia: the COVID-19 Mental Health International Study.

OBJECTIVES: To determine the prevalence of depression and the sociodemographic factors associated with depression in Malaysia during the COVID-19 pandemic METHODS. This study is part of the COVID-19 Mental Health International Study to collect data on the impact of the pandemic on mental health through an online survey. People who were aged ≥18 years, able to read Malay or English, had access to the internet, and consented to participate were asked to complete a pro forma questionnaire to collect their sociodemographic data. The presence of distress and depression was assessed using the English or Malay version of the Center for Epidemiologic Studies Depression Scale. RESULTS: Of 963 participants, 451 (46.8%) had depression and 512 (53.2%) had no depression who were either normal (n = 169, 17.5%) or had distress (n = 343, 35.6%). Participants had higher odds of having depression when living with two people (adjusted odds ratio [AOR] = 3.896, p = 0.001), three people (AOR = 2.622, p < 0.001) or four people (AOR = 3.135, p < 0.001). Participants with three children had higher odds of having depression (AOR = 2.084, p = 0.008), whereas having only one child was a protective factor for depression (AOR = 0.481, p = 0.01). Participants had higher odds of having depression when self-employed (AOR = 3.825, p = 0.003), retired (AOR = 4.526, p = 0.001), being housekeeper (AOR = 7.478, p = 0.004), not working by choice (AOR = 5.511, p < 0.001), or unemployed (AOR = 3.883, p = 0.009). Participants had higher odds of depression when living in a small town (AOR = 3.193, p < 0.001) or rural area (AOR = 3.467, p < 0.001). Participants with no chronic medical illness had lower odds of having depression (AOR = 0.589, p = 0.008). CONCLUSION: In Malaysia during the COVID-19 pandemic, people who are living with two, three, or four people, having three children, living in a small town or rural areas, and having unstable income have higher odds of having depression. Urgent intervention for those at risk of depression is recommended.

Overall mortality trends in Greece during the first period of austerity and the economic crisis (2009-2015).

OBJECTIVES: The economic crisis and the resulting austerity in Greece led to a drastic reduction in healthcare spending, which has been assumed to have impacted people's health. This paper discusses official standardized mortality rates in Greece between 2000 and 2015. METHODS: This study was designed to analyze population-level data and collected data from the World Bank, the Organisation for Economic Co-operation and Development, Eurostat, and the Hellenic Statistics Authority. Separate linear regression models were developed for the periods before and after the crisis and were compared. RESULTS: Standardized mortality rates do not support a previously reported assumption of a specific and direct negative effect of austerity on global mortality. Standardized rates continued to decrease linearly, and their correlation to economic variables changed after 2009. Total infant mortality rates show an overall rising trend since 2009, but the interpretation is unclear because of the reduction in the absolute number of deliveries. CONCLUSIONS: The mortality data from the first six years of the financial crisis in Greece and the decade that preceded do not support the assumption that budget cuts in health are related to the dramatic worsening of the overall health of the Greek people. Still, data suggest an increase in specific causes of death and the burden on a dysfunctional and unprepared health system that is working in an overstretched manner trying to meet needs. The dramatic acceleration of the aging of the population constitutes a specific challenge for the health system. HIPPOKRATIA 2022, 26 (3):98-104.

Employment insecurity, mental health and suicide.

With the economic crisis an increase in suicidality has been reported across Europe but especially in Greece. Τhese reports hit the mass media headlines and were also included in the debate among political parties. The literature suggests that during periods of deep economic crisis, there is an increase specifically in suicides but causality remains unclear. The prevailing picture both in the scientific literature and in the mass media is that the economic crisis acts as a more or less generic risk factor on the entire population putting at risk literally anybody. Two recent studies clearly dispute it by reporting that suicides had increased several months before unemployment increased. Additionally and specifically concerning Greece, where the economic crisis is deeper and more prolonged, the detailed inspection of age and gender specific rates are not in accord with a "male gender" by "unemployment" interaction. Taking into consideration the above and since the rise in suicides also affects prospering countries without high unemployment, including Germany and Norway, another possible explanation is that the changes in the socioeconomic environment and especially in the employment conditions have overstressed vulnerable populations (e.g. mental patients) leading to the increased suicide rates. The problem is that in the majority of the literature the economic crisis/austerity is considered to be a generic risk factor affecting the entire population and subsequently generic horizontal measures are proposed. Unfortunately patients at risk to commit suicide are not considered as such; instead they are rather considered as normal healthy people from the general population who respond with suicide to generic adverse events.

Solar insolation in springtime influences age of onset of bipolar I disorder.

OBJECTIVE: To confirm prior findings that the larger the maximum monthly increase in solar insolation in springtime, the younger the age of onset of bipolar disorder. METHOD: Data were collected from 5536 patients at 50 sites in 32 countries on six continents. Onset occurred at 456 locations in 57 countries. Variables included solar insolation, birth-cohort, family history, polarity of first episode and country physician density. RESULTS: There was a significant, inverse association between the maximum monthly increase in solar insolation at the onset location, and the age of onset. This effect was reduced in those without a family history of mood disorders and with a first episode of mania rather than depression. The maximum monthly increase occurred in springtime. The youngest birth-cohort had the youngest age of onset. All prior relationships were confirmed using both the entire sample, and only the youngest birth-cohort (all estimated coefficients P < 0.001). CONCLUSION: A large increase in springtime solar insolation may impact the onset of bipolar disorder, especially with a family history of mood disorders. Recent societal changes that affect light exposure (LED lighting, mobile devices backlit with LEDs) may influence adaptability to a springtime circadian challenge.

[The concept of temperament and its contribution to the understanding of the bipolar spectrum].

The present article attempts first to provide a historical overview of the concept of temperament,The present article attempts first to provide a historical overview of the concept of temperament,since its foundation by Polybos (4th century B.C.) and the school of Cos, its predominant role in theshaping of the anthropological and humanitarian sciences, until the modern theoretical formulations,such as those proposed by Robert Cloninger and Hagop Akiskal. Secondly, recent literature ispresented, which suggests a strong link of different temperament structures to mental health andpsychopathology. Hans Eysenck (1916-1997) was the first psychologist to establish approaches topersonality differences and to distinguish three dimensions of personality: Neuroticism, Extraversionand Psychotisism. Eysenck was followed by McCrae and Costa who proposed that there are five basicdimensions of personality ("Big Five"). In the mid-1980s, Robert Cloninger developed a distinctivedimensional model of temperament and character traits. Hagop Akiskal emphasized on the affectivecomponents of temperament and their possible connections to mood disorders and creativity.Specifically, temperament assessment seems to help in differentiating between the relationship ofvarious temperaments and the clinical manifestations of bipolar illness. Within the area of mood disorders,specific affective temperaments might constitute vulnerability factors, as well as clinical pictureand illness course modifiers. Viewing mood disorders under this prism gives birth to the concept ofthe bipolar spectrum with major implications for all aspects of mental health research and providingof care. The hyperthymic and the depressive temperaments are related to the more 'classic' bipolarpicture (that is euphoria, grandiose and paranoid thinking, antisocial behavior, psychomotor accelerationand reduced sleep and depressive episodes respectively). On the contrary cyclothymic, anxiousand irritable temperaments are related to more complex pictures and might predict poor responseto treatment, violent or suicidal behavior and high comorbidity. Unipolar disorder diagnosis is oftenchanged due to the fact that a manic or mixed episode can occur after several years of treatment failure.In these cases the evaluation of temperament can prove to be effective in distinguishing betweenunipolar and bipolar depression and thus favoring treatment planning. In addition, temperament assessmentchanges the definition of bipolarity by supporting the concept of "bipolar spectrum". This isa factor that can lead to a rise in prevalence of bipolar cases. Furthermore, the evaluation of temperamenthas shifted our understanding of bipolarity towards the concept of the 'bipolar spectrum'. It hasalso led to an increase in the prevalence of bipolar disorder cases, notably bipolar II, and a decrease in unipolar cases. Finally, incorporating the concept of temperament in our understanding of bipolardisorder constitutes a challenging issue, which can lead to better treatment and outcome of patients.

[Non-conventional pharmacological agents for the treatment of bipolar disorder: Α systematic review of the evidence].

Bipolar disorder (BD) has a complex and variable clinical picture which is characterized by many different phacets and phases and as a result its therapeutical options are also complex and often unsatisfactory. Typically the so-called "mood stabilizers" are used in the treatment of BD and in this class lithium and specific antiepileptics are included. The present study aimed to systematically review the literature concerning the presence of randomized double blind clinical trials of 'non conventional' pharmaceutical treatment options. The present systematic review utilized the PRISMA method and searched the MEDLINE through January 1st 2015 with the use of appropriate key words. In order to identify randomized controlled trials- RCTs a combination of the words "bipolar", "manic", "mania", "manic depression" and "manic depressive" with "randomized" was used. Webpages with lists of trials were also searched including http://clinicaltrials.gov and http://www.clinicalstudyresults.org as well as the official webpages of all pharma companies with products marketed in the treatment of BD. The reference lists of various review papers were also searched. The MEDLINE was searched with the combination of the words "guidelines" or "algorithms" with "mania", "manic", "bipolar", "manicdepressive" or "manic depression" in order to identify articles with treatment guidelines. The reference list of these articles were also scanned. From 3,284 papers which were initially traced, only 47 papers were included in the present study. From those agents studied in acute mania, tamoxifen is efficacious as monotherapy and as combination therapy with lithium and other mood stabilizers, however its safety profile is relatively poor. Allopurinol manifests efficacy in combination with lithium but not with other agents and its safety profile is satisfactory. Methoxyprogesterone is efficacious in combination with mood stabilizers and its safety profile is very good. In acute bipolar depression the combinations of FEWP with carbamazepine and ketamine, modafinil, pramipexole, pregnenolone and maybe armodafinil with mood stabilizers are efficacious. The safety profile of these combinations is medium. The use of celecoxib, lisdexamfetamine and memantine have negative data. Concerning the maintenance treatment, the data are negative for memantine and for Nacetylcysteine. Although most of the data concerning the usefulness of "non-conventional" pharmacotherapeutic agents in the treatment of bipolar disorder are negative, it is encouraging that those agents who have been proven efficacious probably exert their therapeutic effect through pathways which differ from usual and probably different from those classically considered in most biological models of bipolar illness. In this way there constitute new paradigms and open new horizons in the understanding of the disease.

Effects of exercise training with traditional dancing on functional capacity and quality of life in patients with schizophrenia: a randomized controlled study.

OBJECTIVE: To examine the effects of an eight-month exercise training programme with Greek traditional dancing on functional capacity and quality of life in patients with schizophrenia. DESIGN: Randomized controlled trial. SETTING: Sports Medicine Laboratory. SUBJECTS: A total of 31 patients, aged 59.9 ± 14.1 years. INTERVENTIONS: They were randomly assigned either to a Greek traditional dancing programme (Group A) or to a sedentary control group (Group B). MAIN MEASURES: A functional capacity assessment was performed at baseline and the end of the study. Global Assessment of Functioning Scale and Positive and Negative Syndrome Scale were also used. Quality of life was examined using the Quality of Life and Satisfaction questionnaire. RESULTS: After the eight months, Group A increased walking distance in the 6-minute walk test (328.4 ± 35.9 vs. 238.0 ± 47.6 m), sit-to-stand test (19.1 ± 1.8 vs. 25.1 ± 1.4 seconds), Berg Balance Scale score (53.1 ± 2.1 vs. 43.2 ± 6.7), lower limbs maximal isometric force (77.7 ± 25.7 vs. 51.0 ± 29.8 lb), Positive and Negative Syndrome Scale total score (77.0 ± 23.1 vs. 82.0 ± 24.4), Global Assessment of Functioning Scale total score (51.3 ± 15.5 vs. 47.7 ± 13.3) and Quality of Life total score (34.9 ± 5.2 vs. 28 ± 4.5), compared with Group B. CONCLUSIONS: Our results demonstrate that Greek traditional dances improve functional capacity and quality of life in patients with schizophrenia.

Influence of birth cohort on age of onset cluster analysis in bipolar I disorder.

PURPOSE: Two common approaches to identify subgroups of patients with bipolar disorder are clustering methodology (mixture analysis) based on the age of onset, and a birth cohort analysis. This study investigates if a birth cohort effect will influence the results of clustering on the age of onset, using a large, international database. METHODS: The database includes 4037 patients with a diagnosis of bipolar I disorder, previously collected at 36 collection sites in 23 countries. Generalized estimating equations (GEE) were used to adjust the data for country median age, and in some models, birth cohort. Model-based clustering (mixture analysis) was then performed on the age of onset data using the residuals. Clinical variables in subgroups were compared. RESULTS: There was a strong birth cohort effect. Without adjusting for the birth cohort, three subgroups were found by clustering. After adjusting for the birth cohort or when considering only those born after 1959, two subgroups were found. With results of either two or three subgroups, the youngest subgroup was more likely to have a family history of mood disorders and a first episode with depressed polarity. However, without adjusting for birth cohort (three subgroups), family history and polarity of the first episode could not be distinguished between the middle and oldest subgroups. CONCLUSION: These results using international data confirm prior findings using single country data, that there are subgroups of bipolar I disorder based on the age of onset, and that there is a birth cohort effect. Including the birth cohort adjustment altered the number and characteristics of subgroups detected when clustering by age of onset. Further investigation is needed to determine if combining both approaches will identify subgroups that are more useful for research.

[Neurological soft signs in schizophrenia: correlations with age, sex, educational status and psychopathology].

Though the pathobiology of schizophrenia can be examined in multiple levels, the organic notion of brain disease suggests that neurological features will be present. One straightforward, inexpensive method of investigating brain dysfunction in schizophrenia is thought the bedside assessment of neurological abnormalities with a standard neurological examination. Neurological abnormalities are traditionally classified as "hard signs" (impairments in basic motor, sensory, and reflex behaviors, which do not appear to be affected in schizophrenia) and "soft signs", which refer to more complex phenomena such as abnormalities in motor control, integrative sensory function, sensorimotor integration, and cerebral laterality. Additionally, neurological soft signs (NSS) are minor motor and sensory abnormalities that are considered to be normal in the course of early development but abnormal when elicited in later life or persist beyond childhood. Soft signs also, have no definitive localizing significance but are indicative of subtle brain dysfunction. Most authors believe that they are a reflection not only of deficient integration between the sensory and motor systems, but also of dysfunctional neuronal circuits linking subcortical brain structures such as the basal ganglia, the brain stem, and the limbic system. Throughout the last four decades, studies have consistently shown that NSS are more frequently present in patients with schizophrenia than in normal subjects and non-psychotic psychiatric patients. However, the functional relevance of NSS remains unclear and their specificity has often been challenged, even though there is indication for a relative specificity with regard to diagnosis, or symptomatology. Many studies have considered soft signs as categorical variables thus hampering the evaluation of fluctuation with symptomatology and/or treatment, whereas other studies included insufficient number of assessed signs, or lacked a comprehensive assessment of extrapyramidal symptomatology. Factors such as sex, age or family history of schizophrenia, are said to influence the performance of neurological examination, whereas relative few studies have provided longitudinal follow-up data on neurological soft signs in a sufficient number of patients, in order to address a possible deterioration of neurological functions. Finally, one additional difficulty when analyzing the NSS literature lies in the diversity of symptoms that are evaluated in the studies and/or non-standardized procedures or scoring. We will review some basic issues concerning recurrent difficulties in the measurement and definition of soft signs, as well as controversies on the significance of these signs with respect to clinical subtyping of schizophrenia, and social and demographic variables.

Position statement of the European Psychiatric Association (EPA) on the value of antidepressants in the treatment of unipolar depression.

This position statement will address in an evidence-based approach some of the important issues and controversies of current drug treatment of depression such as the efficacy of antidepressants, their effect on suicidality and their place in a complex psychiatric treatment strategy including psychotherapy. The efficacy of antidepressants is clinically relevant. The highest effect size was demonstrated for severe depression. Based on responder rates and based on double-blind placebo-controlled studies, the number needed to treat (NNT) is 5-7 for acute treatment and four for maintenance treatment. Monotherapy with one drug is often not sufficient and has to be followed by other antidepressants or by comedication/augmentation therapy approaches. Generally, antidepressants reduce suicidality, but under special conditions like young age or personality disorder, they can also increase suicidality. However, under the conditions of good clinical practice, the risk-benefit relationship of treatment with antidepressants can be judged as favourable also in this respect. The capacity of psychiatrists to individualise and optimise treatment decisions in terms of 'the right drug/treatment for the right patient' is still restricted since currently there are no sufficient powerful clinical or biological predictors which could help to achieve this goal. There is hope that in future pharmacogenetics will contribute significantly to a personalised treatment. With regard to plasma concentration, therapeutic drug monitoring (TDM) is a useful tool to optimize plasma levels therapeutic outcome. The ideal that all steps of clinical decision-making can be based on the strict rules of evidence-based medicine is far away from reality. Clinical experience so far still has a great impact.

[Development of the Risk Assessment Suicidality Scale (RASS): a population-based study].

Suicide and suicide attempts are significant and costly public health problems. In order to prevent suicidal and other self-injurious behavior, research on the multiple factors involved in these behaviors with comprehensive and user-friendly instruments is necessary. The aim of the current study was to construct a self-report instrument with emphasis on the items which describe suicide-related behavior itself rather than strongly related clinical features on the basis of a general population study. Twelve items comprising a new scale were applied to 734 subjects from the general population (40.6% males and 59.4% females) aged 40.8 +/- 11.5, along with the STAI and the CES-D. The scoring method was developed on the basis of frequency table of responses to the individual scale items. The factor analysis returned 3 factors explaining 59.19% of total variance (Intention, Life, and History). The Cronbach's alpha was 0.85 for the Intention, 0.69 for the Life and 0.52 for the History subscale. The RASS is a reliable and valid instrument which might prove valuable in the assessment of suicidal risk in the general population as well as in mental patients.

Is anticonvulsant treatment of mania a class effect? Data from randomized clinical trials.

Our aim was to evaluate the efficacy and tolerability of anticonvulsant agents for the treatment of acute bipolar mania and ascertain if their effects on mania are a "class" effect. We conducted a systematic review of randomized controlled trials (RCTs) with placebo or active comparator, in acute bipolar mania in order to summarize available data on anticonvulsant treatment of mania/mixed episodes. We searched (PubMed/MEDLINE) with the combination of the words "acute mania" and "clinical trials" with each one of the following words: "anticonvulsants/antiepileptics,""valproic/valproate/divalproex,""carbamazepine,""oxcarbazepine,""lamotrigine,""gabapentin,""topiramate,""phenytoin,""zonisamide,""retigabine,""pregabalin,""tiagabine,""levetiracetam,""licarbazepine,""felbamate," and "vigabatrin." Original articles were found until November 1, 2008. Data from 35 randomized clinical trials suggested that not all anticonvulsants are efficacious for the treatment of acute mania. Valproate showed greater efficacy in reducing manic symptoms, with response rates around 50% compared to a placebo effect of 20-30%. It appears to have a more robust antimanic effect than lithium in rapid cycling and mixed episodes. As valproate, the antimanic effects of carbamazepine have been demonstrated. Evidences did not support the efficacy of the gabapentin, topiramate as well as lamotrigine as monotherapy in acute mania and mixed episodes. Oxcarbazepine data are inconclusive and data regarding other anticonvulsants are not available. Anticonvulsants are not a class when treating mania. While valproate and carbamazepine are significantly more effective than placebo, gabapentin, topiramate, and lamotrigine are not. However, some anticonvulsants may be efficacious in treating some psychiatric comorbidities that are commonly associated to bipolar illness.

Problems in determining efficacy and effectiveness of antidepressants.

Antidepressants play the major role in treating depressive patients not only due to the fact that they have to undergo the most rigorous proof of efficacy but also because they are easy to apply in the everyday clinical practice. Nearly all psychiatrists and general practitioners treating depressive patients agree about the relevance of antidepressants in the treatment of depressive patients. However, a number of meta-analytic studies recently challenged this belief and it has been put up for discussion to psychiatry/clinical psychopharmacology whether the efficacy of antidepressants is clinically relevant. Despite that all medication were judged to have sufficient data to receive approval from the FDA and the EMA and other agencies worldwide, some authors went further and questioned the effectiveness of antidepressants. They even proposed that "alternative" therapies of unproven efficacy or of proven negative efficacy should be preferred to medication. These authors do not take into consideration that for methodological reasons it is not acceptable to deduce too extensive conclusions. Some assumptions they rely on, like the suggestion of NICE, which regards a mean placebo-verum difference of 3 HAM-D points as clinically relevant, is downright arbitrary on statistical grounds, and not supported by empirical findings or by expert opinion. It seems that the difference in change in HAM-D score between the active drug and placebo is somewhere between 2 and 3, with maybe some agents performing a little better than others. It is uncertain whether initial severity determines response; different interpretations exist. However, much more important for the evaluation of the clinical relevance is the result of the responder/remitter analysis, which compares the relative frequency of these categories between the placebo and verum groups. This approach results in a number needed to treat (NNT) of 5-7. In evidence-based medicine such a NNT is traditionally regarded as a sign of moderate to strong efficacy and corresponds to the referring values of many therapies, which e.g. are standard therapies in internal medicine. However, from many meta-analyses it is clear that when concepts of evidence-based medicine and health economy are applied, which are far away from clinical thinking, problems occur and results are very difficult to interpret in clinical terms.

Towards a genetically validated new affective temperament scale: a delineation of the temperament phenotype of 5-HTTLPR using the TEMPS-A.

BACKGROUND: Although it has been described that affective temperaments are associated with the 5-HTTLPR, less attention was paid to the association between this polymorphism and subscales and items related to each affective temperament. The aim of our study was to investigate the association of affective temperament subscales and individual items with the s allele of the 5-HTTLPR. METHOD: 138 psychiatrically healthy women completed the TEMPS-A questionnaire and were genotyped for 5-HTTLPR. Scores of subjects on the temperament scales, subscales and items in the three genotype and the two phenotype groups were compared using ANOVA. We selected items with significantly different mean scores between the three genotype groups and the two phenotype groups separately and performed item analysis. RESULTS: Subjects in the different 5-HTTLPR genotype and phenotype groups have significantly different score on scales measuring depressive, cyclothymic, irritable and anxious temperaments, and several subscales composing these temperamental scales. Subjects in the three genotype groups scored significantly different on 11 items, 8 of these remained in a derived genotype scale after item analysis. Subjects in the two phenotype groups had significantly different scores on 12 items, 9 of them were retained in a derived phenotype scale after item analysis. LIMITATIONS: Our sample was relatively small and included only women. CONCLUSIONS: Our data provide support for the association of affective temperaments with the s allele. Although the cyclothymic temperament shows the strongest association, all temperaments within the depressive superfactor have a similar share in this association. The newly derived 5-HTTLPR Phenotype Scale shows strong association with 5-HTTLPR genotype and phenotype, therefore this scale should be further investigated in relation to psychiatric disorders, as well as psychological traits and temperaments.

Functional outcome in bipolar disorder: the role of clinical and cognitive factors.

INTRODUCTION: Few studies have examined the clinical, neuropsychological and pharmacological factors involved in the functional outcome of bipolar disorder despite the gap between clinical and functional recovery. METHODS: A sample of 77 euthymic bipolar patients were included in the study. Using an a priori definition of low versus good functional outcome, based on the psychosocial items of the Global Assessment of Functioning (GAF, DSM-IV), and taking also into account their occupational adaptation, the patients were divided into two groups: good or low occupational functioning. Patients with high (n = 46) and low (n = 31) functioning were compared on several clinical, neuropsychological and pharmacological variables and the two patient groups were contrasted with healthy controls (n = 35) on cognitive performance. RESULTS: High- and low-functioning groups did not differ with respect to clinical variables. However, bipolar patients in general showed poorer cognitive performance than healthy controls. This was most evident in low-functioning patients and in particular on verbal memory and executive function measures. CONCLUSIONS: Low-functioning patients were cognitively more impaired than highly functioning patients on verbal recall and executive functions. The variable that best predicted psychosocial functioning in bipolar patients was verbal memory.

Is it possible to predict the long-term response to venlafaxine with the use of biological markers and psychophysiological methods?

INTRODUCTION: The present study investigated whether it is possible to predict the medium term response to venlafaxine using biological markers and psychophysiological methods. MATERIAL: Fourteen (14) patients aged 21-60 years suffering from Major Depression according to DSM-IV were included in the study. METHODS: The SCAN v 2.0 and the IPDE were used to assist clinical diagnosis. Patients were investigated with electrooculogram (EOG), Pattern-Reversal Visual Evoked Potentials (PR-VEPs), Dexamethasone Suppression Test (DST), D-fenfluramine Challenge Test, and brain Single Photon Emission Tomography (SPECT). Venlafaxine 150-225 mg per os daily was administered. The follow-up period was 2 years. STATISTICAL ANALYSIS: Chi-square test and ANOVA were used for the analysis of data. RESULTS: There was a lower left globus pallidus regional cerebral blood flow in patients with better response. On the contrary, chronic patients were closer to normality. DISCUSSION: The results of the current study provide preliminary evidence concerning our ability to predict response to venlafaxine and to understand its way of action.

Beneficial effect of long-acting injectable risperidone on the neurocognitive deficit of a schizophrenic patient: A case report.

We report the case of a 37-year-old female patient suffering from schizophrenia, disorganized type. Adherence to treatment was always a major problem. During the last 2 years the patient was disorganized and was refusing treatment. Since the patient was already receiving a very high (double) dose per os, it was decided to administer two 50 ml ampoules of long-acting, injectable risperidone plus 5 mg of haloperidol per os daily. After 80 days of treatment, all positive, negative and even neurocognitive symptoms improved markedly. Extrapyramidal side effects did not appear at any stage of treatment. The most impressive neurocognitive improvement concerned the clock drawing test, which was in parallel with her improvement in both the positive and negative symptoms of the PANSS.
