- Assessing Executive Dysfunction in Neurodegenerative Disorders: A Critical Review of Brief Neuropsychological ToolsPublication . Moreira, HS; Costa, AS; Castro, SL; Lima, CF; Vicente, SGExecutive function (EF) has been defined as a multifaceted construct that involves a variety of high-level cognitive abilities such as planning, working memory, mental flexibility, and inhibition. Being able to identify deficits in EF is important for the diagnosis and monitoring of several neurodegenerative disorders, and thus their assessment is a topic of much debate. In particular, there has been a growing interest in the development of neuropsychological screening tools that can potentially provide a reliable quick measure of EF. In this review, we critically discuss the four screening tools of EF currently available in the literature: Executive Interview-25 (EXIT 25), Frontal Assessment Battery (FAB), INECO Frontal Screening (IFS), and FRONTIER Executive Screen (FES). We first describe their features, and then evaluate their psychometric properties, the existing evidence on their neural correlates, and the empirical work that has been conducted in clinical populations. We conclude that the four screening tools generally present appropriate psychometric properties, and are sensitive to impairments in EF in several neurodegenerative conditions. However, more research will be needed mostly with respect to normative data and neural correlates, and to determine the extent to which these tools add specific information to the one provided by global cognition screening tests. More research directly comparing the available tools with each other will also be important to establish in which conditions each of them can be most useful.
- Sexual dysfunction in women with Parkinson's diseasePublication . Varanda, S; Ribeiro da Silva, J; Costa, AS; Amorim de Carvalho, C; Alves, JN; Rodrigues, M; Carneiro, GBACKGROUND: Sexual dysfunction in women with Parkinson's disease is poorly understood and research in this area is scarce. The objectives of this study were sexual function characterization in female Parkinson's disease patients, description of sexual dysfunctions, correlation with disease characteristics, and comparison with matched healthy controls. METHODS: Social and demographic data from consecutive female patients with Parkinson's disease and matched healthy controls were collected. The following instruments were used: UPDRS, the Hoehn and Yahr scale, the Beck Depression Inventory-II, the Female Sexual Function Index, and the Sexual Dysfunction Inventory. The only exclusion criterion was cognitive deterioration precluding comprehension of the study scope and its instruments. RESULTS: Of the 95 patients identified, 61 were included. Mean age was 66 years (range 40-89 years), and mean disease duration was seven years (range 1-18 years). Twenty-nine presented an akinetic-rigid syndrome, 25 tremoric disease, and, the remaining, a mixed type of disease. Mean "on" total/part III UPDRS scores were 46 ± 15.0 and 31 ± 8.9. Sexual dysfunction was present in 86.9% of patients and 79.0% of controls, according to the Female Sexual Function Index (p < .01), and in 57.4% of patients and 22.6% of controls, according to the Sexual Dysfunction Inventory (p < .001). Multivariate binary logistic regression identified age and depressive symptoms as positive predictors in the severity of sexual dysfunction. Disease duration, UPDRS part III score, Hoehn and Yahr stage, and antiparkinsonian medication did not show significant predictive value. CONCLUSIONS: Sexual dysfunction is more prevalent in women with Parkinson's disease than in controls and is predicted by older age and severity of depressive symptoms. © 2016 International Parkinson and Movement Disorder Society.
