Cognitive impairment in long-COVID and its association with persistent dysregulation in inflammatory markers.

Objective: To analyze the potential impact of sociodemographic, clinical and biological factors on the long-term cognitive outcome of patients who survived moderate and severe forms of COVID-19. Methods: We assessed 710 adult participants (Mean age = 55 ± 14; 48.3% were female) 6 to 11 months after hospital discharge with a complete cognitive battery, as well as a psychiatric, clinical and laboratory evaluation. A large set of inferential statistical methods was used to predict potential variables associated with any long-term cognitive impairment, with a focus on a panel of 28 cytokines and other blood inflammatory and disease severity markers. Results: Concerning the subjective assessment of cognitive performance, 36.1% reported a slightly poorer overall cognitive performance, and 14.6% reported being severely impacted, compared to their pre-COVID-19 status. Multivariate analysis found sex, age, ethnicity, education, comorbidity, frailty and physical activity associated with general cognition. A bivariate analysis found that G-CSF, IFN-alfa2, IL13, IL15, IL1.RA, EL1.alfa, IL45, IL5, IL6, IL7, TNF-Beta, VEGF, Follow-up C-Reactive Protein, and Follow-up D-Dimer were significantly (p<.05) associated with general cognition. However, a LASSO regression that included all follow-up variables, inflammatory markers and cytokines did not support these findings. Conclusion: Though we identified several sociodemographic characteristics that might protect against cognitive impairment following SARS-CoV-2 infection, our data do not support a prominent role for clinical status (both during acute and long-stage of COVID-19) or inflammatory background (also during acute and long-stage of COVID-19) to explain the cognitive deficits that can follow COVID-19 infection.

Personality Characteristics of Children and Adolescents with Anxiety Disorder from a Maternal Perspective: A Brief Report.

The present study assessed the personality characteristics of children and adolescents with anxiety disorder from a maternal perspective. A total of 48 children and adolescents aged between 8 and 17 years participated in this study, which was organized as follows: a clinical group (24 children and adolescents with anxiety disorders and their respective mothers) and a control group (24 children and adolescents without psychiatric diagnosis and their mothers). The participants were submitted to the WASI, CBCL, MASC-2, and EPQ-J tests and their mothers to the SRQ-20 and PIC-2 tests. The results showed higher rates of internalizing symptoms in the clinical group. In addition, patients showed less interest in hobbies, less adherence to social organizations, impairment in social activities, and commitment to school performance compared to the control group. There was a positive correlation between the mothers' symptoms and each of the following PIC-2 domains: somatic concern (p < 0.01) and psychological discomfort (p < 0.01). In conclusion, youths with AD showed a withdrawn and reserved personality profile, involving distrust of impulses and avoidance of interactions with peers. Furthermore, psychoemotional problems of mothers adversely influenced the perception followed by anxiety and adjustment characteristics. More studies are needed to assess the maternal personality in youths with anxiety.

Self-regulation in youth with bipolar disorder

Objectives: To examine the composition of self-regulation in pediatric bipolar disorder (PBD) through the relationship between executive functions, emotion processing, and family environmental factors. Methods: 58 participants (36 with PBD and 22 controls), ages 12-17, were assessed using the Barratt Impulsiveness Scale (BIS), Conners' Continuous Performance Test (CPT-II), Wisconsin Cards Sorting Test (WCST), Computerized Neurocognitive Battery Emotion Recognition Test-Facial Emotion Recognition Test (PENNCNB ER-40), and Expressed Emotion Adjective Checklist Questionnaire (EEAC). Results: Adolescents with PBD displayed significant deficits in all three spheres when compared to the control group. Emotion processing correlated negatively with inhibition and attention, and correlated positively with mental flexibility/working memory. Family environmental factors correlated negatively with mental flexibility/working memory and emotion processing, and positively with attention and inhibition. These correlations indicate that better inhibitory control, attention, and mental flexibility/working memory are associated with greater emotion processing and a fitter family environment. Conclusion: This study is the first to investigate all of the components of self-regulation deficits simultaneously in patients with PBD. Results suggest that self-regulation is essential for a comprehensive perspective of PBD and should be assessed in an integrative and multifaceted way. Understanding that self-regulation is impacted by the abovementioned factors should influence treatment and improve the functional impairments of daily life observed in this population.

Psychological demands of health professionals in the initial phase of the COVID-19 pandemic

Abstract Recent literature emphasizes how the specific stressors of the COVID-19 outbreak affect the general population and frontline professionals, including those conducting support or backup activities in health units, which can lead to vicarious traumatization. Vicarious traumatization has been used to describe negative emotional reactions in mental health professionals who assist or treat victims of traumatic events. Thus, the aim of this article is to report the actions used in the face of the psychological demands of professionals in a hospital, who were not on the frontline of COVID-19. We collected their sociodemographic information and checked the psychological impact using the depression, anxiety, and stress scale (DASS-21), which was followed by a psychoeducational program (topics related to COVID-19 control and prevention), and individual psychological care for the most severe cases. A total of 118 professionals participated in this study; they were between 20 and 67 years old. Mild to moderate anxiety was observed in 36.5% of the medical teams, 83.3% of the administrative staff, and 65.7% of general service workers, while stress symptoms were observed in 80.2%, 83.3%, and 59.9%, respectively. Depressive symptoms (35.3%) were more frequent in general service workers. The medical teams reported the benefits of primary psychological care, while the other professionals demanded more institutional support services related to the prevention and use of personal protective equipment. This study highlights relevant psychological demands that have repercussions on the daily lives of professionals. The psychoeducational program was considered positive regarding clarification actions. However, it was not perceived as effective in reducing fear, which may result from vicarious traumatization and requires other intervention modalities.

Memory training combined with 3D visuospatial stimulus improves cognitive performance in the elderly: pilot study.

Studies suggest that the engagement of aged participants in cognitive stimulation programs can reduce expected cognitive decline associated with age. OBJECTIVE: To evaluate the effects of memory training (MT) associated with three-dimensional multiple object tracking (3D-MOT) NeuroTracker (NT) in the elderly. METHODS: Forty-four participants (>60 years of age) were recruited and randomly distributed into two groups: experimental (EG; n=22) and comparative (CG; n=22). Both groups performed 12 one-hour MT sessions, twice a week, consisting of specific computerized stimuli associated with teaching of mnemonic strategies; 10 minutes of NT was part only of the EG's sessions. In pre- and post-training periods, both groups were evaluated using a sociodemographic questionnaire, neuropsychological assessment, as well as a specific measure offered by NT. RESULTS: Both groups benefited from the MT and reported more positive feelings regarding their memory and quality of life. However, the EG obtained better results in tests consistent with the strategies trained and which involved attentional resources, reaction time, visual processing speed, episodic, semantic, subjective and working memory as well as aspects of social cognition. CONCLUSIONS: This study showed that the combination of MT and 3D-MOT contributed for a better cognitive performance in the EG. Thus, the results of the present study encourage further research and the development of combined cognitive interventions for the elderly population with and without cognitive deficits.

Estudos sugerem que o envolvimento de idosos em programas de estimulação cognitiva pode reduzir o declínio cognitivo esperado associado à idade. OBJETIVO: Avaliar os efeitos de um treinamento de memória (TM) associado a um estímulo visuoespacial tridimensional (3D-MOT) NeuroTracker (NT) em idosos. MÉTODO: Quarenta e quatro participantes (>60 anos) foram recrutados e distribuídos aleatoriamente em dois grupos: experimental (GE; n=22) e comparativo (GC; n=22). Ambos os grupos realizaram 12 sessões do TM de uma hora, duas vezes por semana, consistindo em estímulos computadorizados específicos associados ao ensino de estratégias mnemônicas; apenas nas sessões do GE foram utilizados 10 minutos com o NT. Nos períodos pré- e pós-treinamento, ambos os grupos foram avaliados por meio de questionário sociodemográfico, avaliação neuropsicológica e medidas cognitivas específicas do NT. RESULTADOS: Ambos os grupos se beneficiaram do TM e relataram sentimentos mais positivos em relação à memória e à qualidade de vida. No entanto, o GE obteve melhores resultados em testes consistentes com as estratégias treinadas e que envolviam recursos atencionais, tempo de reação, velocidade de processamento visual, memória episódica, semântica, subjetiva e de trabalho, além de aspectos da cognição social. CONCLUSÕES: Este estudo mostrou que a combinação do TM e 3D-MOT contribuiu para um melhor desempenho cognitivo no GE. Dessa forma, os resultados do presente estudo incentivam novas pesquisas e o desenvolvimento de intervenções cognitivas combinadas para a população idosa com e sem déficits cognitivos.

Psychological evaluation of children victims of sexual abuse: development of a protocol.

Sexual abuse (SA) is associated with significant psychological problems in childhood, making it increasingly important to develop evaluation protocols. This study examined clinical aspects and cognitive measures of 49 children (24 with SA history and 25 controls). It employed a SA assessment questionnaire, clinical evaluations of posttraumatic stress disorder, risk indicators and neuropsychological tests in order to elaborate a specific forensic psychological evaluation protocol for this population. Conflicting couples (80%), separated parents (68%) and parents' alcohol/drug abuse (76%) were revealed as major risk factors. Fathers represented the primary perpetrator (24%). The main cognitive complaint was difficulty concentrating. Regarding the association between clinical and cognitive variables, it was observed that children who were anxious or referred to having fear, difficulties with operational memory and difficulty sleeping, had more trouble performing tasks that required attention and memory (operational, immediate and late). Children with SA history demonstrated inferior performance in visual attention/task switching and memory; with an emphasis in the loss of set in the Wisconsin test. The findings suggest the possibility of a primary attention deficit in children with SA history, possibly influencing the performance of other cognitive functions.

Longitudinal Neuropsychological Assessment in Two Elderly Adults With Attention-Deficit/Hyperactivity Disorder: Case Report.

The neuropsychological deficits in attention-deficit/hyperactivity disorder (ADHD) may present clinical features similar to mild and/or major neurocognitive disorder and may act as a confounding factor, making it difficult to detect cognitive decline. In this paper, we present the results of longitudinal neuropsychological evaluations in two elderly women with ADHD. Three neuropsychological assessments were performed in two women with ADHD (60 and 77 years old) between 2010 and 2013 at intervals varying from 12 to 15 months. We used structural magnetic resonance imaging to rule out significant abnormalities that could account for cognitive impairment. The results showed two different cognitive profiles with fluctuations in performance over these 2 years, sometimes with improvement and sometimes with decline of some functions such as attention, memory, inhibitory control, and reaction time. To minimize confounding aspects of these fluctuations in clinical practice, we used a longer follow-up with the application of a reliable change index and a minimum of three spaced assessments to provide a more consistent baseline cognitive profile. Our findings did not indicate a consistent cognitive decline, suggesting a less pessimistic perspective about cognitive impairments that could be a prodrome of ADHD-related dementia.

Impairment in planning tasks of children and adolescents with anxiety disorders.

Anxiety disorders are associated with poor neuropsychological performance in attention and memory. However, little is known about the impact of these difficulties on other cognitive functions, such as planning. The ability to plan, including attention, working memory and set-shifting components, can be assessed by the Tower of Hanoi task (ToH). This study evaluated seventy-one participants, aged from 7-17 years. Thirty-seven subjects met DSM-IV diagnostic criteria for at least one anxiety disorder and 34 individuals comprised the controls. The neuropsychological tests used were: the ToH, a problem-solving task, involves planning ability and other executive functions (working memory, attentional control and cognitive flexibility); for the assessment of processing speed and problem-solving, the Vocabulary/Matrix Reasoning subtests of the Wechsler Abbreviated Scale of Intelligence was used to measure for estimated-IQ in both groups. The groups were compared with a generalized linear model controlling for age, IQ and ADHD comorbidity. Compared with controls, anxiety disorders subjects made more errors and required more time to complete the ToH. Children and adolescents with anxiety disorders have poorer planning ability compared to subjects without anxiety disorders, and the difficulty in planning is affected by interference from other cognitive functions, such as attention, working memory, cognitive flexibility and problems-solutions.

Memory training and benefits for quality of life in the elderly: A case report / Treino de memória e seus benefícios na qualidade de vida do idoso: relato de caso

ABSTRACT Studies emphasize the training of cognitive functions to decrease losses in the population. Memory training associated with neurotracker was performed by an 80-year-old man with memory complaints. A battery for measuring memory, quality of life and stress was initially applied and showed low scores. The patient underwent a program for stimulating memory and attention comprising 32 sessions (2 weekly sessions of 90 minutes each). The post-test follow-up showed improvements in the process of storage and retrieval of episodic and working memory, greater use of strategies, faster information processing speed, as well as reduction in complaints and positive impact on quality of life. The results suggest that the use of Neurotracker for training cognitive processes is valid for cognitive rehabilitation programs to promote improvements in quality of life in the elderly.

RESUMO Estudos enfatizam o treinamento de funções cognitivas para diminuição de prejuízos na população. Um treino de memória associado ao neurotracker foi realizado com homem, 80 anos, com queixas de memória. Foi usada uma bateria para aferição da memória, qualidade de vida e estresse nos quais apresentou baixos escores. Ingressou em programa de estimulação da memória e atenção por 32 sessões (2 sessões semanais de 90 minutos). No pós-teste apresentou melhoras no processo de armazenamento e evocação da memória episódica e de trabalho, maior uso de estratégias, rapidez de processamento de informações, bem como, redução de queixas e repercutindo positivamente na qualidade de vida. Os resultados sugerem que o uso do neurotracker para o treinamento de processos cognitivos se mostra consistentes como programas de reabilitação cognitiva corroborando a melhora da qualidade de vida em idosos.

Attention-based classification pattern, a research domain criteria framework, in youths with bipolar disorder and attention-deficit/hyperactivity disorder.

OBJECTIVE: The National Institute of Mental Health has initiated the Research Domain Criteria (RDoC) project. Instead of using disorder categories as the basis for grouping individuals, the RDoC suggests finding relevant dimensions that can cut across traditional disorders. Our aim was to use the RDoC's framework to study patterns of attention deficit based on results of Conners' Continuous Performance Test (CPT II) in youths diagnosed with bipolar disorder (BD), attention-deficit/hyperactivity disorder (ADHD), BD+ADHD and controls. METHOD: Eighteen healthy controls, 23 patients with ADHD, 10 with BD and 33 BD+ADHD aged 12-17 years old were assessed. Pattern recognition was used to partition subjects into clusters based simultaneously on their performance in all CPT II variables. A Fisher's linear discriminant analysis was used to build a classifier. RESULTS: Using cluster analysis, the entire sample set was best clustered into two new groups, A and B, independently of the original diagnoses. ADHD and BD+ADHD were divided almost 50% in each subgroup, and there was an agglomeration of controls and BD in group B. Group A presented a greater impairment with higher means in all CPT II variables and lower Children's Global Assessment Scale. We found a high cross-validated classification accuracy for groups A and B: 95.2%. Variability of response time was the strongest CPT II measure in the discriminative pattern between groups A and B. CONCLUSION: Our classificatory exercise supports the concept behind new approaches, such as the RDoC framework, for child and adolescent psychiatry. Our approach was able to define clinical subgroups that could be used in future pathophysiological and treatment studies.

Facial emotion recognition in bipolar disorder: a critical review.

OBJECTIVE: Literature review of the controlled studies in the last 18 years in emotion recognition deficits in bipolar disorder. METHOD: A bibliographical research of controlled studies with samples larger than 10 participants from 1990 to June 2008 was completed in Medline, Lilacs, PubMed and ISI. Thirty-two papers were evaluated. RESULTS: Euthymic bipolar disorder presented impairment in recognizing disgust and fear. Manic BD showed difficult to recognize fearful and sad faces. Pediatric bipolar disorder patients and children at risk presented impairment in their capacity to recognize emotions in adults and children faces. Bipolar disorder patients were more accurate in recognizing facial emotions than schizophrenic patients. DISCUSSION: Bipolar disorder patients present impaired recognition of disgust, fear and sadness that can be partially attributed to mood-state. In mania, they have difficult to recognize fear and disgust. Bipolar disorder patients were more accurate in recognizing emotions than depressive and schizophrenic patients. Bipolar disorder children present a tendency to misjudge extreme facial expressions as being moderate or mild in intensity. CONCLUSION: Affective and cognitive deficits in bipolar disorder vary according to the mood states. Follow-up studies re-testing bipolar disorder patients after recovery are needed in order to investigate if these abnormalities reflect a state or trait marker and can be considered an endophenotype. Future studies should aim at standardizing task and designs.

OBJETIVO: Revisão da literatura de estudos controlados publicados nos últimos 18 anos sobre déficits no reconhecimento de emoções no transtorno bipolar. MÉTODO: Foi realizada uma pesquisa bibliográfica no Medline, Lilacs, PubMed e ISI, selecionando-se o período de 1990 a junho de 2008. Foram incluídos apenas estudos controlados, que tivessem uma das amostras com mais de 10 participantes, totalizando 32 artigos. RESULTADOS: Bipolares eutímicos apresentaram prejuízo no reconhecimento de nojo e medo. Em mania, mostraram dificuldade para reconhecer medo e tristeza. Transtorno bipolar pediátrico e crianças de risco apresentam dificuldade para reconhecer emoções nos rostos de adultos e de crianças. Bipolares foram mais precisos para reconhecer emoções do que os pacientes esquizofrênicos. DISCUSSÃO: Pacientes com transtorno bipolar apresentam prejuízo no reconhecimento de nojo, medo e tristeza, os quais podem ser apenas em parte atribuídos ao estado de humor. No episódio maníaco, eles têm dificuldade para reconhecer medo e nojo. Entretanto, eles são mais precisos no reconhecimento de emoções do que pacientes deprimidos e esquizofrênicos. Crianças com transtorno bipolar apresentam tendência a julgar expressões faciais extremas como sendo de intensidade leve ou moderada. CONCLUSÃO: Déficits afetivos e cognitivos em bipolares sofrem variações dependendo do estado de humor. Estudos de seguimento, reavaliando pacientes após a remissão dos sintomas, são necessários para investigar se estas anormalidades refletem um estado ou traço da doença e se podem ser consideradas endofenótipos. Estudos futuros devem padronizar tarefas e metodologia.
