Neuropsychological assessment of mild cognitive impairment in Latinx adults: A scoping review.
Conclusions: Future studies of diagnosis of MCI in Latinx individuals should report cultural details and use of appropriate neuropsychological assessment tools and normative data. This is important to accurately estimate the prevalence of MCI in Latinx individuals. (PsycInfo Database Record (c) 2020 APA, all rights reserved) (Source: Neuropsychology)

Change in self-reported cognitive symptoms after mild traumatic brain injury is associated with changes in emotional and somatic symptoms and not changes in cognitive performance.
Conclusions: These findings indicate that improvements in subjective cognitive symptoms after MTBI co-occur with improvements on other subjective metrics, but are not related to improvements in objectively measured cognitive functioning.

Wakeful rest benefits before and after encoding in anterograde amnesia.
Conclusions: Post-encoding wakeful rest alone substantially improves retention in amnesic patients. While pre-encoding wakeful rest elicits inconsistent benefits in amnesics, reduced retention following both pre- and post-encoding task engagement suggests that pre-encoding activity may still be relevant. Overall, our findings support consolidation interference explanations of forgetting in anterograde amnesia. (PsycInfo Database Record (c) 2020 APA, all rights reserved) (Source: Neuropsychology)

Dopaminergic medication improves cognitive control under low cognitive demand in Parkinson’s disease.
Objective: Dopamine agonists are the main pharmacological intervention for the motor symptoms of Parkinson’s disease (PD). However, dopaminergic medication has been associated with disinhibitory psychopathology in some patients. The aim of this study was to test the effect of dopaminergic medication on inhibitory control in patients with PD using the paced Random Number Generation task (RNG), which requires inhibition of prepotent counting in series to produce a random sequence of numbers. Method: Twenty-three PD patients performed RNG on and off dopaminergic medication. Cognitive load was manipulated by performing RNG a...

Comparing patient and informant ratings of depressive symptoms in various stages of Alzheimer’s disease.
Objective: Using a multimethod approach, this study assessed the relationship between patient and informant ratings of depression in Alzheimer’s disease (AD) in a manner that better represents the progressive course of AD, and allows for elucidation of specific cognitive domains that may explain changes in respondent agreement. Method: Case data (N = 16,297) were provided by the National Alzheimer’s Coordinating Center (NACC). A series of contingency analyses were performed to assess the relationship between patient and informant agreement across levels of impairment in individuals with AD. Patients and informants were...
