To date, only limited research has concurrently investigated the presence of rapid eye movement sleep behavior disorder (RBD) and other features associated with Parkinson disease (PD) and dementia with Lewy bodies (DLB) in people presenting with mild cognitive impairment (MCI). As a first step towards a longitudinal research project, the present study explored the relationships between MCI, RBD, and depression in 108 older adults who presented with subjective memory complaints but were not known to have a neurodegenerative condition...

OBJECTIVES: Research estimates that a significant percentage of individuals with mild cognitive impairment (MCI) experience functional difficulties. In addition to reduced accuracy on measures of everyday function, cross-sectional research has demonstrated that speed of performing instrumental activities of daily living (IADLs) is slowed in individuals with MCI. The present study investigated whether baseline and longitudinal changes in speed and accuracy of IADL performance differed between persons with MCI and cognitively normal peers...

Social cognitive abilities are impaired in Alzheimer disease and other dementias. Recent studies suggested that social cognitive abilities might be also impaired in mild cognitive impairment (MCI). Current meta-analysis aimed to summarize available evidence for deficits in theory of mind (ToM) and emotion recognition in MCI. In this meta-analysis of 17 studies, facial emotion recognition and ToM performances of 513 individuals with MCI and 693 healthy controls were compared. Mild cognitive impairment was associated with significant impairments falling in the medium effect sizes range in ToM ( d = 0...

Motor disturbances in delirious patients are common, but their relationship to cognition and severity of illness has not been studied. We examined motor subtypes in an older age inpatient population, their relationship to clinical variables including delirium, and their association with 1-year mortality in a prospective study, using the Confusion Assessment Method, Acute Physiology and Chronic Health Evaluation II, Montreal Cognitive Assessment (MoCA), Barthel Index, and Delirium Rating Scale-Revised 98 (DRS-R98)...

Primary progressive aphasia (PPA) is a heterogeneous neurodegenerative condition in which the most prominent clinical feature is language difficulties. Other cognitive domains have been described to remain unaffected at the early stages of the disease and, therefore, excluded from diagnostic criteria. However, we show in this article that executive function (EF) disorders may be present in the 3 variants (nonfluent/agrammatic, logopenic, and semantic) of PPA. We also illustrate changes in language and EF by means of a 3-year behavioral and neuroimaging longitudinal study of a patient suffering from the semantic variant of PPA...

Late-life depression (LLD) is a common emotional and mental disability in the elderly population characterized by the presence of depressed mood, the loss of interest or pleasure in daily activities, and other depression symptoms. It has a serious effect on the quality of life of elderly individuals and increases their risk of developing physical and mental diseases. It is an important area of research, given the growing elderly population. Brain functional connectivity modifications represent one of the neurobiological biomarker for LLD even if to date remains poorly understood...

BACKGROUND/AIMS: Mild cognitive impairment (MCI) is present in up to 34% of patients with early-stage Parkinson disease (PD); however, it is difficult to detect subtle impairment without objective cognitive testing. METHODS: Data were obtained from the Parkinson Progression Marker Initiative. All 341 participants were administered the Montreal Cognitive Assessment (MoCA) and a brief neuropsychological battery. Participants were classified as PD-MCI if MoCA was <26 or if they scored ≥1 standard deviation below the normative mean in 2 or more domains, based upon established criteria...

Parkinson disease (PD) is a neurodegenerative disorder characterized by motor and nonmotor symptoms. Nonmotor symptoms include cognitive deficits and impairment in emotions recognition ability associated with loss of dopaminergic neurons in the substantia nigra and with alteration in frontostriatal circuits. In this review, we analyzed the studies on social cognition ability in patients with PD. We searched on PubMed and Web of Science databases and screening references of included studied and review articles for additional citations...

OBJECTIVES: While basic activities of daily living hierarchically decline in dementia, little is known about the decline of individual instrumental activities of daily living (IADLs). The objective of this study was to assess initiative and performance deficits in IADLs in dementia. METHODS: A total of 581 carers completed the revised Interview for Deterioration in Daily Living Activities in Dementia 2 to rate their relative's everyday functioning. RESULTS: Initiating and performing IADLs deteriorated hierarchically, while people with dementia were consistently most impaired in initiating using the computer and managing finances...

BACKGROUND: Improvements in cognition often accompany fitness improvements in older adults, and research suggests insulin-like growth factor 1 (IGF-1) may influence this association. No prior work has examined this in mild cognitive impairment (MCI). We predicted that IGF-1 would moderate the relationship between cognition and aerobic endurance improvement, such that greater baseline IGF-1 would accompany a stronger relationship between cognition and aerobic endurance change. METHOD: Twenty-seven individuals with MCI completed assessments of aerobic endurance (2-minute step test [2MST]) and global cognition (Modified Mini-Mental State [3MS]) before and after a 6-month period of twice-weekly exercise...

Visual hallucinations (VH) are a common feature of Parkinson disease (PD); however, the cognitive profile preceding the onset of VH has not yet been established. The present study investigated longitudinal neuropsychological performance of patients with PD who developed VH during follow-up compared to a group who did not develop VH. The patient groups were matched for demographic and disease severity variables at their baseline assessments. Patients who developed VH displayed impaired performance at baseline on measures of psychomotor speed, executive functioning, reaction time, and attention compared to patients who did not develop VH...

OBJECTIVE: Apathy is one of the most frequent neuropsychiatric symptoms encountered in Alzheimer disease (AD). Early diagnosis and timely treatment of apathy in AD seem to be of great importance, since apathy has been associated with poor disease outcome, reduced daily functioning, and caregiver distress. DESIGN: Within this context, we conducted an extensive electronic search from the databases included in the National Library of Medicine as well as PsychInfo and Google Scholar for studies that have investigated the effect of pharmacological and nonpharmacological treatments of apathy in AD...

Increase in serum homocysteine is shown to be a potential risk factor for cognitive impairment. Evidence suggests that vitamin B supplementation may reduce cognitive decline by lowering the homocysteine levels. The current meta-analysis evaluated the efficacy of folic acid along with vitamin B12 and/or B6 in lowering homocysteine, thereby attenuating cognitive decline in elderly patients with Alzheimer disease or dementia. Randomized controlled trials (RCTs) comparing the efficacy of folate and B vitamin supplementation in patients with cognitive decline secondary to Alzheimer disease or dementia were identified using the keywords, "homocysteine, hyper-homocysteinemia, B vitamin, vitamin B6, B12, folic acid, cognitive, Alzheimer's disease, and dementia...
