INTRODUCTION: Parkinson's disease is a progressive neurological disorder characterized by the preferential loss of dopaminergic neurons in the substantia nigra, which project to the striatum. The disease is characterized by prominent motor symptoms, which are its cardinal features. Consequently, Parkinson's disease has been primarily considered a disorder of movement. However, increasing evidence has indicated that Parkinson's disease affects not only the motor domain but also the cognitive domain...

Alzheimer's disease (AD) is a progressive neurodegenerative disorder that presents predominantly with impairments in learning and memory. Patients with AD are also susceptible to false memories, a clinically relevant memory distortion where a patient remembers an incorrect memory that they believe to be true. The use of cognitive strategies to improve memory performance among patients with AD by reducing false memories has taken on added importance given the lack of disease-modifying agents for AD. However, existing evidence suggests that cognitive strategies to reduce false memories in patients with AD are of limited effectiveness, although these strategies may be useful at earlier stages of the disease...

INTRODUCTION: Previous studies have found that music paired with lyrics at encoding may improve the memory performance of patients with mild Alzheimer's disease (AD). To further explore memory for different types of musical stimuli, the current study examined both implicit and explicit memory for music with and without lyrics compared to spoken lyrics. METHOD: In this mixed design, patients with probable mild AD (n = 15) and healthy older adults (n = 13) listened to auditory clips (song, instrumental, or spoken lyrics varied across three sessions) and then had their memory tested...

INTRODUCTION: Research evaluating the neuropsychological effects of cannabis has yielded mixed findings, with some studies finding cognitive deficits in cannabis users (primarily in learning and memory) and others finding no significant effects. It is important to understand how clinicians perceive this discrepancy in the empirical literature. However, no studies have assessed neuropsychologists' beliefs regarding the effects of cannabis on cognitive functioning. Thus, this study sought to evaluate how patient and cannabis-use factors influence neuropsychologists' perceptions of cannabis's cognitive effects...

INTRODUCTION: HIV-associated neurocognitive disorders (HAND) are estimated to affect approximately 50% of infected individuals at any one time. Dispersion, a type of intraindividual variability in neurocognitive test performance, has been identified as a potential behavioral marker of HAND; however, the specificity of dispersion to HAND and how it is influenced by participant effort when taking neurocognitive tests remain unclear. METHOD: Data were analyzed from 996 (474 HIV-, 522 HIV+) men enrolled in the Multicenter AIDS Cohort Study (MACS)...

OBJECTIVE: The ability to detect covert markers of incipient cognitive decline among older adults before cognitive decline becomes overtly evident on traditional cognitive tests represents an important topic of research. Exaggerated reactions to novelty, reflected in novelty-induced increases in action planning latencies ("novelty effect"; NE) and low openness to experience (openness), have been previously associated with incipient cognitive decline among older adults who appeared cognitively normal at baseline...

OBJECTIVES: Unusually high engagement in expressive suppression (i.e., purposeful regulation of overt affect) has been associated with poorer performance on executive functioning (EF) and motor-sequence learning tasks. As such, expressive suppression represents one possible source of fluctuations in executive test performance. However, the relationship between expressive suppression and EF and motor performance has not yet been examined in older adults, who are more prone to EF and motor fluctuations than are younger adults...

INTRODUCTION: Previous research has found mixed results when assessing the association between a parent's history of depressive symptoms and a child's abilities on measures of executive functioning. The purpose of this study was to replicate and expand upon these findings by evaluating the influence of a parent's depressive symptoms on a young person's executive functioning. METHOD: As part of a larger study, 135 children (54.8% female, aged 8-12) and one biological parent completed diagnostic screening interviews...

INTRODUCTION: It is well established that behavioral variant frontotemporal dementia can impair social and emotional function. However, there is no consensus regarding how Alzheimer's disease can affect facial expression recognition. We aim to systematically review all the literature addressing this issue over the last 10 years. METHOD: We conducted a search based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). The search for literature was undertaken on 19 September 2017, using Pubmed, SciELO, BIREME, and Thomson Reuters Web of Science electronic databases...

AIM: Previous studies indicate the effectiveness of motor imagery training in stroke patients. To determine whether patients showing chronic visuospatial neglect symptoms may profit from motor imagery training, it is important to assess how the brain implements motor imagery when cortical systems involved in attentional control are impaired. METHOD: Therefore, in this pilot study, nine chronic neglect patients with right-hemispheric stroke performed motor imagery of a finger opposition task during functional magnetic resonance imaging (fMRI)...

INTRODUCTION: Studies have shown that skilled and disabled readers recall central ideas, which are important to the overall comprehension of the text, to a greater extent than peripheral, less important ideas after reading. However, readers with attention-deficit/hyperactivity disorder (ADHD) recall significantly fewer central ideas than skilled readers. The present study was designed to examine whether difficulties in identifying, attending, and/or retrieving central ideas underlie their centrality deficit...

INTRODUCTION: Historically, most studies about awake brain surgery have focused on language or motor functions. More recently, other cognitive functions have also been assessed. However, a clear overview of the neuropsychological tests or test paradigms that are used during such procedures is missing. The primary research question of this review is: What neuropsychological tests or paradigms are used during awake brain surgery? This review aims to give an extensive overview about the assessment of cognition during awake brain surgery...

OBJECTIVES: The aim of this study was to compare the two most commonly prescribed classes of atypical antipsychotic medications (i.e., -pines and -dones) with regard to their effects on cognition in patients with schizophrenia. DATA SOURCES: Ovid Technologies web-based software was used to search the Medline and PsycINFO computerized databases to identify articles that met the inclusion criteria. REVIEW METHODS: The search was limited to papers published after 1990, written in English, employing human subjects, using atypical antipsychotics, using a within-subjects design or control group of patients with schizophrenia for comparisons, using participants aged from 18-65, and employing standardized neuropsychological measures...

INTRODUCTION: Normal aging is associated with deficits in various aspects of spoken language production, including idea generation and selection, and involves activity in frontal brain areas including left inferior frontal cortex (LIFG). These conceptual preparation processes, largely involving executive control, precede formulation and articulation stages and are critical for language production. Noninvasive brain stimulation (e.g., transcranial direct current stimulation, tDCS) has proven beneficial for age-related fluency and naming deficits, but this has not been extended to conceptual preparation mechanisms...

Prospective monitoring of posttraumatic amnesia (PTA) status is recommended following traumatic brain injury (TBI). Use of patients' subjective reports is, however, still common and necessary in some circumstances. It is therefore important to understand how patients' self-reported first memories relate to prospective measures and how reliable these reports remain over time. In the present study, patients with moderate-severe TBI in PTA were asked about their first and last memories surrounding the injury daily and were administered the Westmead Post-Traumatic Amnesia Scale (WPTAS)...

INTRODUCTION AND OBJECTIVES: Many women report diminished memory function during the second or third trimesters of pregnancy, but objective neuropsychological tests often fail to show any decrement in performance. The present paper systematically reviews published studies that have investigated this phenomenon over the past 25 years and considers newer studies showing that affective changes occur during gestation in a subset of pregnant women. METHOD: A systematic search was conducted to identify articles relevant to pregnancy and memory function...

OBJECTIVE: Although metabolic syndrome (MetS) has been shown to increase the risk of cognitive decline, it still remains unclear whether the risk is related to MetS as a whole or its individual factors. The aim of the present study was to explore whether MetS or its individual factors are associated with a lower cognitive function in older adults in a Mediterranean population using latent variable modeling. METHOD: Neurocognitive data from 640 Greek-Cypriot community dwellers (female 59...

INTRODUCTION: This study examined false positive rates on embedded performance validity tests (PVTs) in older adults grouped by cognitive status. METHOD: The research design involved secondary analysis of data from the National Alzheimer's Coordinating Center database. Participants (N = 22,688) were grouped by cognitive status: normal (n = 10,319), impaired (n = 1,194), amnestic or nonamnestic mild cognitive impairment (MCI; n = 5,414), and dementia (n = 5,761)...
