The aim of this study was to determine whether frailty in older adults is associated with the risk of subsequent dementia. A total of 8,722 older adults from the English Longitudinal Study of Ageing were followed-up every two years until they reported a diagnosis of dementia, died, or were right censored. Frailty was defined using a frailty index comprised of 47 health deficits. To test if cognitive function influences the relationship between frailty and incident dementia, the analyses were repeated according to lower or upper three quartiles of baseline cognitive function...

TANK-binding kinase 1 (TBK1) loss-of-function (LoF) mutations are known to cause frontotemporal dementia (FTD) and amyotrophic lateral sclerosis (ALS), often combined with memory deficits early in the disease course. We performed targeted resequencing of TBK1 in 1253 early onset Alzheimer's disease (EOAD) patients from 8 European countries to investigate whether pathogenic TBK1 mutations are enriched among patients with clinical diagnosis of EOAD. Variant frequencies were compared against 2117 origin-matched controls...

Rapid eye movement sleep behavior disorder (RBD) is a brain disorder, characterized by the dream enactment during rapid eye movement (REM) sleep due to a lack of physiologic muscle atonia and increased muscle twitching. Schenk was the first to describe this disorder in 1986; however, few authors reported in the 1970-1980s loss of physiological muscle atonia combined with dream enactment in the course of brainstem disorders and as a consequence of alcoholism and antidepressant treatment. RBD affects less than 1% of the adult population, but can be found in up to 25-50% of neurodegenerative disorders including Parkinson's disease, multisystem atrophy, and dementia with Lewy body...

Chronic kidney disease (CKD) is a condition characterized by progressive and irreversible deterioration of renal function due to the reduction of nephron mass for a period of at least three months. The prevalence of CKD is roughly 10% in the general population but increases with age, affecting more than one-third of people older than 65. Frailty is a condition usually found in elderly people, characterized by weakness, motility, and balance issues, with a declined ability to resist stressors leading to increased risks of adverse health outcomes including falls, fracture, hospitalization, institutionalization, disability, dependence, dementia, poor quality of life, and death...

AIM: Pneumonia is one of the major causes of mortality in older adults. As the average lifespan has extended and new modalities to prevent or treat pneumonia are developed, the factors that affect the length of hospital stay (LHS) and in-hospital mortality of older patients with pneumonia have changed. The object of the present study was to determine the factors associated with LHS and mortality as a result of pneumonia among older patients with dementia. METHODS: With a retrospective cohort study design, we used the data derived from the Japanese Administrative Database and diagnosis procedure combination/per diem payment system (DPC/PDPS) database...

Purpose of review Alzheimer's disease (AD) and frontotemporal dementia can often be diagnosed accurately with careful clinical history, cognitive testing, neurological examination, and structural brain MRI. However, there are certain circumstances wherein detection of specific biomarkers of neurodegeneration or underlying AD pathology will impact the clinical diagnosis or treatment plan. We will review the currently available biomarkers for AD and frontotemporal dementia (FTD) and discuss their clinical importance...

Dementia is a major public health issue with rising prevalence rates, but many individuals remain undiagnosed. Accurate and timely diagnosis is key for the optimal targeting of interventions. A noninvasive, easily measurable peripheral biomarker would have greatest utility in population-wide diagnostic screening. Epigenetics, including DNA methylation, is implicated in dementia; however, it is unclear whether epigenetic changes can be detected in peripheral tissue. This study aimed to systematically review the evidence for an association between dementia and peripheral DNA methylation...

The objective of this study is to report a Brazilian patient and his family with inclusion body myopathy associated with Paget's disease of bone and frontotemporal dementia (IBMPFD). A systematic review of the literature on the valosin-containing protein (VCP) mutation was also performed. The proband (patient) was initially treated as a case of possible refractory polymyositis with Paget's disease and later as an inclusion body myopathy. However, after admission to our service, and considering his personal and familial antecedents, whole exome sequencing was performed revealing valosin-containing protein (VCP) c...

PURPOSE: Periodic discharges in EEG and a history of rapidly progressive dementia are known to be associated with sporadic Creutzfeld-Jakob Disease (sCJD). Doubts regarding this rare but fatal diagnosis can arise, when episodic symptoms (seizures, psychiatric features, speech disturbances) are present and the EEG shows epileptiform discharges within this periodicity. This scenario may indicate non-convulsive status epilepticus (NCSE), which is - in contrast to sCJD - a treatable and frequent condition...

BACKGROUND: Although it is well known that Alzheimer's disease (AD) is associated with the progressive accumulation of amyloid β-peptide (Aβ) in the human brain, its pathogenic role has yet to be completely clarified. Aβ moves from the blood-brain barrier to the plasma and an increased Aβ production in brain could be associated with higher Aβ concentrations in blood. A recent study has evaluated Aβ-40 and Aβ-42 levels in human red blood cells (RBCs) with evidence of age-dependent higher Aβ concentration in RBCs...

BACKGROUND: Minimally invasive specific biomarkers of neurodegenerative diseases (NDs) would facilitate patient selection and disease progression monitoring. We describe the assessment of circulating brain-enriched microRNAs as potential biomarkers for Alzheimer's disease (AD), frontotemporal dementia (FTD), Parkinson's disease (PD), and amyotrophic lateral sclerosis (ALS). METHODS: In this case-control study, the plasma samples were collected from 250 research participants with a clinical diagnosis of AD, FTD, PD, and ALS, as well as from age- and sex-matched control subjects (n = 50 for each group), recruited from 2003 to 2015 at the University of Pennsylvania Health System, including the Alzheimer's Disease Center, the Parkinson's Disease and Movement Disorders Center, the Frontotemporal Degeneration Center, and the Amyotrophic Lateral Sclerosis Clinic...

PURPOSE OF REVIEW: Cerebral amyloid angiopathy (CAA) is diagnosed primarily as a cause of lobar intracerebral hemorrhages (ICH) in elderly patients. With improving MRI techniques, however, the role of CAA in causing other symptoms has become clear. Recognizing the full clinical spectrum of CAA is important for diagnosis and treatment. In this review we summarize recent insights in clinical CAA features, MRI biomarkers, and management. RECENT FINDINGS: The rate of ICH recurrence in CAA is among the highest of all stroke subtypes...
