Suicidal Behavior and Early Maladaptive Schemas and Schema Domains.

ABSTRACT: Suicidal behavior is a risk factor for suicide attempts. Identifying the factors that increase suicidal behavior risk is paramount for overall suicide prevention efforts. One model that may contribute to our understanding of the relationship between early life experiences and suicidal behavior is the schema theory. This study aimed to examine suicidal behavior, early maladaptive schemas (EMSs), and schema domains using a large Brazilian nonclinical sample. The study included 19,060 individuals. We assessed sociodemographic variables, suicidal behavior (Suicidal Behavior Questionnaire), and EMSs (Young Schema Questionnaire) using an online, Web-based survey. Our results showed that, when comparing participants with no ideation with those with serious suicide attempts, we found significant statistical differences in all EMSs (all p 's < 0.05), with higher scores in those with serious suicide attempts. Our results suggest that specific unmet emotional needs during childhood can affect mental health and result in serious suicide attempts in adulthood.

Hippocampal neurochemical markers in bipolar disorder patients following the first-manic episode: A prospective 12-month proton magnetic resonance spectroscopy study.

OBJECTIVE: Previous studies reported decreased N-acetyl aspartate and increased Glx (the sum of glutamate plus glutamine) in bipolar disorder. Since these studies included patients at different stages of illness, it is unknown whether these changes have a causal role or a consequence of multiple episodes and treatments. The studies in early-stage bipolar disorder patients have the potential to provide answers to these issues. Therefore, we evaluated N-acetyl aspartate and Glx levels in hippocampi of first-episode bipolar disorder patients and health subjects at baseline and at 12 months, and examined the impact of episode recurrence on these measures. METHOD: We used single-voxel proton magnetic resonance spectroscopy to compare the hippocampal neurometabolites ( N-acetyl aspartate and Glx) levels between 41 patients with bipolar disorder following recovery from their first-manic episode and 27 matched healthy subjects at recruitment and 12 months later. We also compared N-acetyl aspartate and Glx levels between patients who had a recurrence of a mood episode and those who did not. RESULTS: There was no main effect of either group (diagnosis) or time for hippocampal N-acetyl aspartate and Glx levels in bipolar disorder patients and healthy subjects. We also did not find any group-by-time interaction for the levels of these metabolites. There were also no differences in N-acetyl aspartate and Glx between patients who experienced a recurrence of a mood episode and those who did not over 12-month follow-up. CONCLUSION: Our data suggest that N-acetyl aspartate and Glx levels are not altered in early stage bipolar disorder. Further, these data suggest that episode recurrence in early stages does not have a significant impact on the levels of these metabolites. These may suggest that there may be an early window for intervention to potentially arrest neuroprogression of the disease.

Impact of depressive episodes on cognitive deficits in early bipolar disorder: data from the Systematic Treatment Optimization Programme for Early Mania (STOP-EM).

BACKGROUND: Although manic episodes reportedly contribute to cognitive deficits in bipolar I disorder, the contribution of depressive episodes is poorly researched. AIMS: We investigated the impact of depressive episodes on cognitive function early in the course of bipolar I disorder. METHOD: A total of 68 patients and 38 controls from the Systematic Treatment Optimization Programme for Early Mania (STOP-EM) first-episode mania programme were examined. We conducted (a) a cross-sectional analysis of the impact of prior depressive episodes on baseline cognitive function and (b) a prospective analysis assessing the contribution of depression recurrence within 1 year following a first episode of mania on cognitive functioning. RESULTS: The cross-sectional analysis showed no significant differences between patients with past depressive episodes compared with those without, on overall or individual domains of cognitive function (all P>0.09). The prospective analysis failed to reveal a significant group×time interaction for cognitive decline from baseline to 1 year (P = 0.99) in patients with a recurrence of depressive episodes compared with those with no recurrence. However, impaired verbal memory at baseline was associated with a depression recurrence within 1 year. CONCLUSIONS: Although deficits in all domains of cognitive function are seen in patients early in the course of bipolar disorder, depressive episodes do not confer additional burden on cognitive function. However, poorer verbal memory may serve as a marker for increased susceptibility to depression recurrence early in the course of illness.

Use of Citicoline in Attention-Deficit/Hyperactivity Disorder: A Pilot Study.

OBJECTIVES: Attention-deficit/hyperactivity disorder (ADHD) is a prevalent neurobehavioral disorder in school-aged children. Although there are several drug treatment options, some patients do not have adequate therapeutic responses to conventional medications or experience considerable adverse effects. Citicoline is an endogenous molecule that has beneficial effects on attention, impulsivity, and memory and is a potential treatment for ADHD. This study aimed to evaluate the effect of citicoline in pediatric patients diagnosed with ADHD. METHODS: This randomized, crossover, double-blind, placebo-controlled clinical trial included with patients aged 7-12 years diagnosed with ADHD. RESULTS: As a result, no statistically significant difference was noted between the use of citicoline and placebo in the evaluated parameters. The treatment had no adverse effects. CONCLUSIONS: Citicoline seems to be a safe molecule to be administered in the pediatric age group. Further studies are required to assess the therapeutic potential of citicoline in ADHD.

Validity and Reliability of the Brazilian Version of the Cognitive Reserve Assessment Scale in Health (CRASH).

OBJECTIVE: As the elderly population increases, it is important to identify factors that may reduce risks of dementia in the general population. One such factor is the concept of cognitive reserve (CR). The present study analyzed the psychometric properties of the Cognitive Reserve Assessment Scale in Health (CRASH) in the Brazilian population, which was originally developed to measure CR in individuals with severe mental illness. We also investigated the relationship between the CRASH and clinical or sociodemographic variables. METHODS: This study was conducted with 398 individuals. We assessed sociodemographic variables and depression, anxiety and stress symptoms (DASS-21), using a web-based survey. We constructed a confirmatory factor analysis (CFA) model in order to test the goodness of fit of the factor structure proposed in the original CRASH study. RESULTS: The McDonald's hierarchical ω for CRASH using CFA parameters was 0.61 and Cronbach's alpha coefficient indicated good internal consistency when considering all items (∝ = 0.7). CONCLUSIONS: Our results suggest that CRASH can be used to assess CR in the general population in Brazil.

Cognitive impairment in school-aged children with early trauma.

Exposure to traumatic events during childhood is often associated with the development of psychiatric disorders, cognitive impairment, and poor functioning in adulthood. However, few studies have examined cognitive function, including executive function, memory, and attention, in school-aged children with early trauma compared with age- and sex-matched controls. We recruited 30 medication-naive children between 5 and 12 years of age with a history of early severe trauma from a foster care home, along with 30 age- and sex-matched controls. Psychiatric diagnoses were based on Kiddie Schedule for Affective Disorders and Schizophrenia Epidemiologic Version (K-SADS-E) for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria and were confirmed with a clinical interview. The neuropsychologic battery was tailored to assess broad cognitive domains such as learning/working memory, executive function, attention, verbal/premorbid intellectual functioning, and impulsivity. There was a higher prevalence of subsyndromal symptoms in children with a history of childhood trauma, although they rarely met all of the diagnostic criteria for a disorder. Moreover, lower estimated intellectual functioning scores were associated with subsyndromal symptoms in children with a history of trauma, and they performed more poorly on the Digits Span Test of the Wechsler Intelligence Scale for Children-III Edition, suggesting attention impairment. There is a high prevalence of subsyndromal symptoms in school-aged children with trauma and an attention impairment, which may contribute to a cumulative deficit early in cognitive development. These findings further support the need for early interventions that can prevent cognitive impairment when childhood trauma occurs.

Impact of the COVID-19 pandemic on mental health among local residents in South of Brazil: during pandemic times, youth sleep matters.

INTRODUCTION: Social isolation has been associated with poor sleep quality and mental health problems during the COVID-19 pandemic. However, most studies have investigated heterogeneous samples subjected to varying social distancing policies and did not focus on a single local profile subject to homogeneous prevention policies. OBJECTIVES: To evaluate the impact of the COVID-19 pandemic on mental health and sleep quality in a specific region in the South of Brazil where the populations have similar culture and local governments have adopted similar social distancing policies. METHODS: This study was conducted with 327 individuals aged 18-72 years, living in the Vale do Taquari area, Brazil. We assessed sociodemographic variables with a standardized protocol, symptoms of depression, anxiety, and stress with the Depression, Anxiety and Stress Scale-21 (DASS-21), sleep quality with the Pittsburgh Sleep Quality Index (PSQI), and post-traumatic stress symptoms with the Impact of Event Scale (IES-R), using a web-based online survey. RESULTS: Our results showed that sleep dysfunction moderated the effects of age on psychological symptoms, indicating that younger participants who had poorer sleep quality had worse mental health. Furthermore, participants with more perceived stress during the pandemic and more sleep dysfunction reported more symptoms of anxiety and post-traumatic stress. CONCLUSION: Psychological symptoms were not related to social isolation duration but were related to the subjective perception that the pandemic interfered with life and generated stressful situations. These results may help governments make important decisions about protection and isolation measures in future waves of COVID-19 infection.

Peripheral blood levels of brain-derived neurotrophic factor in patients with post-traumatic stress disorder (PTSD): A systematic review and meta-analysis.

BACKGROUND: Brain-derived neurotrophic factor (BDNF) plays a crucial role in the survival, differentiation, growth, and plasticity of the central nervous system (CNS). Post-traumatic stress disorder (PTSD) is a complex syndrome that affects CNS function. Evidence indicates that changes in peripheral levels of BDNF may interfere with stress. However, the results are mixed. This study investigates whether blood levels of BDNF in patients with post-traumatic stress disorder (PTSD) are different. METHODS: We conducted a systematic search in the major electronic medical databases from inception through September 2019 and identified Observational studies that measured serum levels of BDNF in patients with PTSD compared to controls without PTSD. RESULTS: 20 studies were eligible to be included in the present meta-analysis. Subjects with PTSD (n = 909) showed lower BDNF levels compared to Non-PTSD controls (n = 1679) (SMD = 0.52; 95% confidence interval: 0.18 to 0.85). Subgroup meta-analyses confirmed higher levels of BDNF in patients with PTSD compared to non-PTSD controls in plasma, not serum, and in studies that used sandwich ELISA, not ELISA, for BDNF measurement. Meta-regressions showed no significant effect of age, gender, NOS, and sample size. CONCLUSIONS: PTSD patients had increased serum BDNF levels compared to healthy controls. Our finding of higher BDNF levels in patients with PTSD supports the notion that PTSD is a neuroplastic disorder.

Emotional memory in bipolar disorder: Impact of multiple episodes and childhood trauma.

BACKGROUND: Emotional memory is a critical amygdala-dependent cognitive function characterized by enhanced memory for emotional events coupled with retrograde amnesia. Our study aims to assess the influence of bipolar disorder (BD), trauma, and the number of mood episodes on emotional memory. METHODS: 53 subjects (33 euthymic patients with BD and 20 healthy controls) answered a clinical assessment, childhood trauma questionnaire (CTQ), and an emotional memory test composed of lists of nouns, including neutral words, one emotional (E), one preceding (E-1) and one following word (E + 1). We assessed for the influence of type, position, diagnosis, trauma, and number of mood episodes in word recall using generalized estimating equations. RESULTS: Controlling for neutral words, BD had a higher recall for E-1 (p = 0.038) and a trend for a higher recall of E (p = 0.055). There was no difference between patients with and without trauma. Patients with BD who suffered multiple mood episodes had a higher recall of E compared to patients with fewer episodes (p = 0.016). LIMITATIONS: Cross-sectional design and small sample size. CONCLUSION: Our results indicate dysfunction in emotional memory in patients with BD, particularly after multiple mood episodes. While we expected an impaired emotional memory, patients with BD showed an increased recall for emotional stimuli and events preceding them. Childhood trauma does not seem to interfere with emotional memory changes in patients with BD. Emotional memory enhancement seems to be a promising marker of progression in BD.

Identifying cognitive subgroups in bipolar disorder: A cluster analysis.

BACKGROUND: Evidence has shown heterogeneity of cognitive function among patients with bipolar disorder (BD). Our study aims to replicate recent findings of cognitive subgroups, as well as we assessed subjective cognitive difficulties and functioning in each cluster. METHODS: Hierarchical cluster analysis was conducted to examine whether there were distinct neurocognitive subgroups based on neurocognitive battery. Cognitive Complaints in Bipolar Disorder Rating Assessment (COBRA) and Functioning Assessment Short Test (FAST) were used to assess subjective cognitive difficulties and functional impairment. RESULTS: We found three distinct subgroups: a first cluster with intact cognition (n = 30, 43.5%), a second cluster with selective cognitive impairment (n = 23, 33.3%), and a third cluster with globally cognitive impairment (n = 16, 23.3%). The intact group had more years of education (p < .001) and higher estimated IQ (p < .001) than globally and selectively impaired subgroups. Additionally, they were younger (p = .011), had an earlier age at bipolar diagnosis (p < .037) and earlier age of first hospitalization (p < .035) compared to individuals with globally cognitive impairment. LIMITATIONS: This is a cross-sectional design with a small sample including only patients from a tertiary hospital. CONCLUSION: Our results give support to the existence of a continuum of severity from patients without impairment to those with poor cognitive functioning. Patients in the intact group seem to have higher cognitive reserve than other two groups. However, they also experienced cognitive complaints and some degree of functional impairment. These findings suggest the importance of using a combo of instruments (e.g., objective and subjective cognitive measures plus functioning instruments) for a complete assessment of patients with BD.

Perceived childhood adversities: Impact of childhood trauma to estimated intellectual functioning of individuals with bipolar disorder.

Maltreatments in childhood may have implications for neurodevelopment that could remain throughout life. Childhood trauma seems to be associated with the onset of bipolar disorder (BD), and its occurrence might accentuate the overall disease impairments related to cognitive deficits in BD. We aimed to evaluate the effects of a history of childhood trauma to estimated intellectual functioning (IQ) of individuals with BD. We included 72 subjects with BD during euthymia. Participants underwent a clinical interview and were assessed through the Childhood Trauma Questionnaire (CTQ) and Wechsler Abbreviated Scale of Intelligence (WASI). Most prevalent trauma subtypes were emotional abuse and neglect (54.1%). A linear regression model that included perceived childhood trauma, family history of severe mental disorders, age at diagnosis and psychotic symptoms during the first episode as main factors showed that only childhood trauma had a significant effect in predicting estimated IQ. Therefore, the history of childhood trauma in individuals with BD may play a role in intellectual development, suggesting that adversities during development result in decreased general cognitive abilities. These results reinforce the need to promote early interventions to protect childhood and to promote the well-being of children, contributing to the growth of healthy adults.

Adjunctive tianeptine treatment for bipolar disorder: A 24-week randomized, placebo-controlled, maintenance trial.

OBJECTIVE: The purpose of this study was to assess the efficacy and tolerability of tianeptine as an adjunctive maintenance treatment for bipolar depression. METHODS: This is a multicenter double-blind randomized placebo-controlled maintenance trial of adjunctive tianeptine 37.5 mg/day. Participants ( n=161) had a Montgomery-Asberg Depression Rating Scale ⩾12 at entry. After eight weeks of open-label tianeptine treatment, those who responded to tianeptine ( n=69) were randomized to adjunctive tianeptine ( n=36) or placebo ( n=33) in addition to usual treatment. Kaplan-Meier estimates and the Mantel-Cox log-rank test were used to evaluate differences in time to intervention for a mood episode between the tianeptine and placebo groups. We also assessed overall functioning, biological rhythms, quality of life, rates of manic switch and serum brain-derived neurotrophic factor levels. RESULTS: There were no differences between adjunctive tianeptine or placebo regarding time to intervention or depression scores in the 24-week double-blind controlled phase. Patients in the tianeptine group showed better performance in the letter-number sequencing subtest from the Wechsler Adult Intelligence Scale at the endpoint ( p=0.014). Tianeptine was well tolerated and not associated with higher risk for manic switch compared to placebo. CONCLUSION: Tianeptine was not more effective than placebo in the maintenance treatment of bipolar depression. There is preliminary evidence suggesting a pro-cognitive effect of tianeptine in working memory compared to placebo.

Translation and cross-cultural adaptation of the Brazilian Portuguese version of the Emotional Memory Scale.

Background Emotional memory is an important type of memory that is triggered by positive and negative emotions. It is characterized by an enhanced memory for emotional stimuli which is usually coupled with a decrease in memory of neutral preceding events. Emotional memory is strongly associated with amygdala function and therefore could be disrupted in neuropsychiatric disorders. To our knowledge, there is no translated and culturally adapted instrument for the Brazilian Portuguese speaking population to assess emotional memory. Objective To report the translation and cross-cultural adaptation of a Brazilian Portuguese version of the Emotional Memory Scale, originally published by Strange et al. in 2003. Methods The author of the original scale provided 36 lists with 16 words each. Translation was performed by three independent bilingual translators. Healthy subjects assessed how semantically related each word was within the list (0 to 10) and what the emotional valence of each word was (-6 to +6). Lists without negative words were excluded (negative selection), most positive and most unrelated words were excluded (positive and semantic selection, respectively), and lists with low semantic relationship were excluded (semantic assessment). Results Five lists were excluded during negative selection, four words from each list were excluded in positive and semantic selection, and 11 lists were excluded during semantic assessment. Finally, we reached 20 lists of semantically related words; each list had one negative word and 11 neutral words. Conclusion A scale is now available to evaluate emotional memory in the Brazilian population and requires further validation on its psychometrics properties.

Conclusions: Our results suggest that CRASH can be used to assess CR in the general population in Brazil.

Saúde mental de pais durante a pandemia da COVID-19 / Parental mental health during COVID-19 pandemic

OBJETIVO: Investigar a saúde mental de pais com filhos pequenos durante a pandemia de COVID-19. MÉTODOS: Foram utilizados questionários elaborados pelo Google Forms, no qual foram aplicados os dados sociodemográficos, e as escalas EADS-21, IES-R, PSQI-BR e WHOQOL-BREF. As análises estatísticas foram realizadas no software estatístico SPSS 21.0 para Windows. Para descrição da amostra, foram utilizadas análises descritivas. Em todos os testes, foi considerada a significância estatística de 0,05. Os 327 participantes foram divididos em três grupos: voluntários sem filhos (Grupo 1), com filhos entre 0 e 6 anos (Grupo 2) e com filhos de 7 anos ou mais (Grupo 3), dos quais todos eram residentes da região Sul do Brasil. RESULTADOS: Os grupos com maior vulnerabilidade em relação à sua saúde mental é o de participantes sem filhos e com filhos de 0 a 6 anos, com maiores escores para as escalas de depressão, ansiedade e estresse, e estresse pós-traumático, em comparação com o grupo com filhos de 7 anos ou mais. CONCLUSÕES: Mesmo que os dados mostrem que todos os grupos estão dentro da normalidade para as escalas aplicadas, faz-se necessário atentar para a saúde mental da população em maior sofrimento psíquico, seja a partir de estratégias desenvolvidas por profissionais de rede de saúde (SUS) e/ou da assistência social (SUAS), seja por projetos municipais/estaduais na busca pela promoção da saúde mental na rede.

OBJECTIVE: Explore the mental health of parents with young children during the COVID-19 pandemic. METHODS: We used questionnaires prepared by Google Forms, applying sociodemographic data, and also the EADS-21, IES-R, PSQI-BR and WHOQOL-BREF scales were applied. Statistical analyzes were performed using SPSS 21.0 statistical software for Windows. To describe the sample, descriptive analyzes were used. In all tests, a statistical significance of 0.05 was considered. Of the 327 participants, they were divided into three groups: volunteers without children (Group 1), with children aged 0 to 6 years (Group 2), and with children aged 7 or over (Group 3). All volunteers were residents from South of Brazil. RESULTS: The groups with the greatest vulnerability in relation to their mental health are those of participants without children and parents with children aged 0 to 6 years, with higher scores for the depression, anxiety and stress, and post traumatic stress symptoms, compared to parents with children aged from 7 years or more. CONCLUSION: even though the data show that all groups are within the normal range for the scales applied, it is necessary to pay attention to the mental health of the population in greater psychological distress, either from strategies developed by health professionals (SUS) and/or or social assistance (SUAS), either by municipal/state projects in the search for the promotion of mental health.

The impact of the COVID-19 pandemic on Quality of Life among Local Residents in south of Brazil

INTRODUCTION: The impact of restrictive measures during the COVID-19 pandemic resulted in negative effects on the Quality of Life (QoL). It is important to evaluate this measure in a specific region with a homogeneous profile and with high rates of transmission during the pandemic in a developing nation as Brazil. OBJECTIVES: The objective of this study was to assess through an online self-reported questionnaire the impact of COVID-19 pandemic on QoL in a specific region in the South of Brazil, called "Vale do Taquari", in the initial stage of the COVID-19 outbreak. METHODS: This study was conducted with 325 individuals. We assessed sociodemographic variables and depression, anxiety, stress symptoms (Depression, Anxiety and Stress Scale-21 (DASS-21), sleep quality (The Pittsburgh Sleep Quality Index PSQI), post-traumatic stress symptoms (Impact of Event Scale-IES-R scale) and QoL (The World Health Organization quality of life assessment (WHOQOL-bref). RESULTS: Reduced psychological symptoms, better sleep quality, shorter duration of social isolation, not experiencing stressful situations during the pandemic, higher education and older age were associated with increased QoL. CONCLUSION: Our results could be used as a historical reference and help assist local authorities to define future intervention strategies, since we will probably need to deal with the deleterious effects of the pandemic even after its complete control.(AU)
