Background and purpose: It remains unclear about the etiopathogenesis of cognitive impairment (CI) in Parkinson's disease (PD). Since diabetes mellitus (DM) has been shown to be associated with CI in several diseases, we examined the association between CI and dysglycemia in PD. Methods: Enrolled PD patients completed a series of clinical and neuropsychological assessments. Motor symptoms were determined by Hohen-Yahr staging (H-Y staging) and Unified Parkinson's Disease Rating Scale - motor score (UPDRS-III)...

There is a lack of consensual tools for evaluating the cognitive side-effects in patients with depression who are treated with electroconvulsive therapy (ECT). The objective of this study was to evaluate the usefulness of the Montreal Cognitive Assessment (MoCA) and of the Mini Mental State Examination (MMSE) to monitor cognitive changes in patients with depression receiving ECT. Cognitive functioning was assessed prospectively in 48 patients with unipolar or bipolar depression before and after an ECT course...

INTRODUCTION: Treatment for pain and related conditions has been identified as the most common reason for Emergency Department (ED) visits. Concerns exist regarding the effects of opioid pain medications on cognition and patient ability to consent for procedures, hospital admission, or to refuse recommended medical interventions. This study was undertaken to identify cognitive skills before and after opioid pain medication in the ED setting. METHODS: This was a prospective study comparing performance on the Mini-Mental Status Examination (MMSE) and Montreal Cognitive Assessment (MoCA) before and after administration of opioid pain medications...

White matter lesions (WMLs) have been associated with cognitive and motor decline. Resting state networks (RSNs) are spatially coherent patterns in the human brain and their interactions sustain our daily function. Therefore, investigating the altered intra- and inter-network connectivity among the RSNs may help to understand the association of WMLs with impaired cognitive and motor function. Here, we assessed alterations in functional connectivity patterns based on six well-defined RSNs-the default mode network (DMN), dorsal attention network (DAN), frontal-parietal control network (FPCN), auditory network (AN), sensory motor network (SMN) and visual network (VN)-in 15 patients with ischemic WMLs and 15 controls...

Olfaction dysfunction is considered as a robust marker of prodromal Parkinson disease (PD). Measurement of olfaction function as a screening test is unsatisfactory due to long lead time interval and low specificity for detection of PD. Use of imaging markers might yield more accurate predictive values and provide bases for combined use of imaging and clinical markers for early PD. Diffusion MRI connectometry was conducted on 85 de novo PD patients in and 36 healthy controls to find: first, white matter tracts with significant difference in quantitative anisotropy between PD groups with various degrees of olfaction dysfunction and second, second fibers with correlation with University of Pennsylvania Smell Identification Test (UPSIT) score in each group using a multiple regression analysis considering age, sex, GDS and MoCA score...

Introduction: Cognitive and gait deficits are common symptoms in Parkinson's disease (PD). Motor-cognitive dual tasks (DTs) are used to explore the interplay between gait and cognition. However, it is unclear if DT gait performance is indicative for cognitive impairment. Therefore, the aim of this study was to investigate if cognitive deficits are reflected by DT costs of spatiotemporal gait parameters. Methods: Cognitive function, single task (ST) and DT gait performance were investigated in 67 PD patients...

BACKGROUND: The MoCA score is a convenient and promising tool for estimating alcoholic patients' global cognitive functioning, a major challenge for all specialized alcohol treatment centers. However, whether or not the score should be corrected for education level and whether the proposed cutoff is relevant in patients with alcohol use disorders (AUD) should be determined. DESIGN: We compared the MoCA scores in patients hospitalized for AUD with and without cognitive impairment (CI) assessed by a battery of neuropsychological tests...

Research into the effects of cognitive aging on route navigation usually focuses on differences in learning performance. In contrast, we investigated age-related differences in route knowledge after successful route learning. One young and two groups of older adults categorized using different cut-off scores on the Montreal Cognitive Assessment (MoCA), were trained until they could correctly recall short routes. During the test phase, they were asked to recall the sequence in which landmarks were encountered (Landmark Sequence Task), the sequence of turns (Direction Sequence Task), the direction of turn at each landmark (Landmark Direction Task), and to identify the learned routes from a map perspective (Perspective Taking Task)...

OBJECTIVES: Human immunodeficiency virus positive (HIV+) individuals report hearing difficulties, but standard audiological tests show no, or small, changes in peripheral hearing ability. The hearing complaints may reflect central nervous system (CNS) auditory processing deficits, rather than middle or inner ear problems, and may result from CNS damage due to HIV infection or treatment. If central auditory task performance and cognitive deficits in HIV+ individuals are shown to be related, then central auditory tests might serve as a "window" into CNS function in these patients...
