Researchers have suggested there is a wide range of neuropsychological deficits individuals with anorexia nervosa (AN) possess, including impairments in nonverbal reasoning, attention and processing speed, memory, and executive functioning. While growing, examination of the neuropsychological functioning of children and adolescents with AN is quite sparse compared to the abundance of research on adults with AN, and the many conflicting findings have been attributed to inconsistent methodologies across studies. This study examined the neuropsychological functioning of children and adolescents with AN by conducting a quantitative study loosely based on Bayless et al. (2002) and Remberk, Namysłowska, Krempa-Kowalewska, Gadaś, and Skalska (2011). Results indicated verbal intellectual functioning was significantly higher than other intellectual domains, and verbal memory was almost significantly higher than nonverbal memory (p = .051). Negative correlations were found between individual subtests and clinical data (e.g., age of onset of AN and duration of AN) as well as the EDI-3 Personal Alienation scale and the BMI-for-age percentile. Clinical implications include providing treatment improving cognitive functioning and implementing a biopsychosocial model.

Dementia is a syndrome characterized by multiple cognitive deficits, that are sufficient to interfere with daily living and social and occupational functioning (Gabrowski & Damasio, 2004). Alzheimer’s Dementia (AD) is the most common cause of dementia in adults and the risk of developing the disease increases with age. Alzheimer’s Dementia is a disease that is misunderstood in Nigeria because of the nature and time of onset of the condition; memory loss associated with Alzheimer’s Dementia is assumed to be a normal part of aging. This report investigates the quality of care that is provided to older adults with Alzheimer’s Dementia in Nigeria and offers recommendations for improved rehabilitation services / text

Contexte : Les répercussions de l’alcool au niveau des fonctions cognitives sont bien documentées. Certaines hypothèses suggèrent que l’alcool affecte des fonctions cognitives spécifiques alors que d’autres avancent l’hypothèse de déficits diffus. Cependant, une ambigüité persiste concernant quelles fonctions cognitives sont le plus touchées par l’alcool, et à quel point la durée d’abstinence affecte la récupération cognitive. Nous avons procédé à une des premières méta-analyses qui s’intéresse aux différentes fonctions cognitives touchées par la consommation problématique d’alcool et à la durée d’abstinence requise pour une récupération au niveau des cognitions. Méthodes : Une recherche de la littérature a permis d’identifier 62 études évaluant les cognitions chez les personnes présentant des troubles liés à l’utilisation d’alcool. Les estimations de la taille d’effet ont été calculées avec la Comprehensive Meta Analysis –V2 pour les 12 domaines cognitifs suivants : quotient intellectuel, fluidité verbale/langage, vitesse de traitement de l’information, mémoire de travail, attention, résolution de problème/fonctions exécutives, inhibition/impulsivité, apprentissage verbal, mémoire verbale, apprentissage visuel, mémoire visuelle, habiletés visuo-spatiales. Parmi ces 12 domaines cognitifs, 3 estimations de la taille d’effet ont été calculées selon les durées d’abstinences suivantes : court- (<1 mois), moyen- (2 à 12 mois) et long- (>1 an) termes. Résultats : Les résultats ont révélé la présence de dysfonctions modérées dans 11 domaines cognitifs durant l’abstinence à court terme, et dans 10 domaines cognitifs pour le moyen-terme. Des dysfonctions cognitives minimales furent notées durant l’abstinence à long-terme. Conclusions : Ces résultats révèlent des déficits cognitifs significatifs et diffus durant la première année d’abstinence. Déficits qui se normalisent après un an. Ces résultats soutiennent l’hypothèse de déficits cognitifs diffus reliés à l’alcoolisme et suggèrent que la cognition devrait faire partie intégrante du traitement d’alcoolisme. / Background: The cognitive repercussions of alcoholism are well documented. However, the literature remains somewhat ambiguous with which distinct cognitive functions are more susceptible to impairment in alcoholism and to how duration of abstinence affects cognitive recovery. Some theories claim alcohol negatively affects specific cognitive functions while others assert that deficits are more diffuse in nature. We performed the first meta-analysis to examine cognition in alcoholism and how duration of abstinence affects cognitive recovery. Methods: A literature search yielded 62 studies assessing cognitive dysfunction among alcoholics. Effect size estimates were calculated using the Comprehensive Meta-Analysis V2, for the following 12 cognitive domains: intelligence quotient, verbal fluency/language, speed of processing, working memory, attention, problem solving/executive functions, inhibition/impulsivity, verbal learning, verbal memory, visual learning, visual memory, and visuo-spatial abilities. Within these 12 domains, 3 effect size estimates were calculated based on abstinence duration and partitioned into short- (<1 month), intermediate- (2 to 12 months) and long- (>1 year) term abstinence. Results: Findings revealed moderate impairment across 11 cognitive domains during short term abstinence with moderate impairment across 10 domains during intermediate term abstinence, and overall small effect size estimates during long term abstinence. Conclusions: Results suggest significant cognitive dysfunction during the first year following abstinence from alcohol and that long term abstinence yields near normalisation of cognitive function. These findings support the diffuse brain deficits hypothesis. Clinical implications suggest that cognition may need to be considered an integral part of the treatment of alcoholism.

Research on factors that contribute to the forms and functions of aggression (reactive, proactive, relational, and overt) is important for informing intervention efforts with aggressive youth. Previous research shows that aggressive youth often have cognitive and social deficits associated with their aggressive behavior. For example, aggressive youth may exhibit deficits in social variables such as social intelligence (i.e., the understanding of behaviors of people and ability to predict outcomes of situations). Hypothetically, this lack of social intelligence may be related to how youth interpret social situations, and could conceivably lead to hostile attributional bias, or the tendency to interpret ambiguous stimuli as hostile. The main purpose of this study was to examine whether HAB mediated the relationship between social intelligence and reactive relational aggression in a sample of detained adolescent boys (ages 12-18). The results failed to support this hypothesis. Supplemental analyses explored whether HAB moderated the relationship between social intelligence and the subtypes of aggression, but results were not consistent with this hypothesis.

Para descrever os achados da espectroscopia de prótons (1H-ERM) na doença de Alzheimer (DA) e no comprometimento cognitivo sem demência (CIND) em uma amostra da comunidade foram avaliados 13 pacientes com DA, 12 com CIND e 15 controles normais. A 1H-ERM foi realizada com voxel de 8 cm3 nas regiões temporal direita, parietal esquerda e occipital medial estudando os metabólitos: N-acetilaspartato (NAA), creatina (Cr), colina (Cho) e mio-inositol (mI). O NAA foi maior nos indivíduos controles do que nos DA e intermediário no CIND; o mI foi maior no grupo DA do que nos controles; a Cho mostrou tendência a estar aumentada na DA e CIND. Correlação entre os testes cognitivos e a 1H-ERM confirmou a hipótese de que alterações metabólicas estão presentes quando do aparecimento das primeiras alterações cognitivas. A espectroscopia pode, em função disso, contribuir para o diagnóstico e seguimento de indivíduos com queixa de memória em indivíduos da comunidade com a possibilidade de diagnósticos mais precoces. / For the description of the proton magnetic resonance spectroscopy (1H-ERM) data in Alzheimer´s disease (AD) and Cognitive Impairment Not Dementia (CIND) in a community set, subjects with AD (n=13), CIND (n=12) and normal control (n=15) were investigated. 1H-ERM was performance with single voxel (8 cm3) placed in temporal, parietal e occipital region and studied metabolites: N-acetylaspartate (NAA), creatine (Cr), choline (Cho) and myo-inositol (mI). NAA concentration was higher in control subjects than AD and intermediated level in CIND patients; mI was higher in patients with AD and CIND; Cho tended to be higher in AD and CIND. Metabolisms changes are present together the first cognitive deficits as showed by correlation between cognitive tests and 1H-ERM. Spectroscopy can be used in the diagnosis and follow-up of individuals with memory complain in the community set with the possibility of early diagnosis

Multiple Sclerosis (MS), an autoimmune disorder marked by inflammation of the central nervous system, is associated with a myriad of symptoms. Individuals with MS are more likely to experience depressive symptoms, perhaps due to perceived cognitive impairments. Thus, we aimed to explore perceived stress and sleep deficits as potential mediators of the association between perceived cognitive deficits and depressive symptoms. We recruited a sample of 77 MS participants from an outpatient, university-based MS clinic in the United States. Participants ranged in age between 30 and 75 years old (M = 51.12; SD = 9.6), with more females than males (83% female; n = 64). Participants completed the Perceived Deficits Questionnaire, the Pittsburgh Sleep Quality Index, the Perceived Stress Scale, and the Center for Epidemiological Studies Depression Scale – Revised. Correlation analyses and mediation analyses were conducted with bootstrapping technique. Statistical analyses revealed that higher levels of perceived cognitive deficits were associated with lower quality of sleep, more perceived stress, and higher levels of depressive symptoms. Additionally, both perceived stress and sleep quality served as a significant mediator in the perceived cognitive impairments and depressive symptoms linkage. Our novel findings demonstrate the importance of underlying mechanisms (e.g., sleep quality and perceived stress) in the conceptualization of MS. Perceived stress and sleep quality are potentially modifiable factors, perhaps serving as a target for future treatment, to buffer risk of MS patients developing depression.
