BACKGROUND: Recently, four neuropathological stages of amyotrophic lateral sclerosis (ALS) with spreading of transactive response DNA-Binding Protein-43 pathology were described. Although 18F-FDG PET has been useful in diagnosis and prognosis of ALS patients, in vivo disease staging using glucose metabolic patterns across the different ALS stages have not been attempted so far. In this study, we investigated whether the discriminant brain regions of the neuropathological stage model can be translated to metabolic patterns for in vivo staging of ALS...

This retrospective cohort study aimed to examine the relationship between herpes zoster ophthalmicus (HZO) and the subsequent risk of dementia using a population-based database. We retrieved the study sample from the Taiwan Longitudinal Health Insurance Database 2005. The study group included 846 patients with HZO, and the comparison group included 2538 patients without HZO. Each patient was individually followed for a 5-year period to identify those patients who subsequently received a diagnosis of dementia...

OBJECTIVE: Mild Cognitive Impairment (MCI) is an early dementia or discrete memory loss. The cognitive deficit in MCI impedes people's daily activities, which influences multiple aspects of thinking and acting including attention, reading, writing, reasoning, language, and judgment. This review aims to assess the outcome of various neuropsychological interventions in treating MCI. MATERIALS AND METHODS: MCI causes memory problems and is characterized by the cognitive damage that is disproportionate about individual education background and age...

We can trace, with high congruence, the clinical syndromes of depression and mania as described over the 20th century in psychiatric textbooks back to 1880 and to the earliest writing of Kraepelin published in 1883. However, this is not the case for Kraepelin's 2 delusional syndromes central to his overall nosology: Dementia Paranoides (later paranoid schizophrenia) and Paranoia. A detailed examination of 28 textbook descriptions of delusional psychoses from 1880 to 1900 reveals a diverse and partially overlapping set of syndromes with an admixture of symptoms and signs that would later be considered indicative of Dementia Paranoides and Paranoia...

Oxidative stress (OS) is one of the factors that cause dementia conditions such as Alzheimer's disease and vascular dementia (VaD). In the pathogenesis of VaD, OS is associated with risk factors that include increased age, hypertension, and stroke. Nicotinamide adenine dinucleotide phosphate (NADPH) oxidases (NOXs) are a molecular source of reactive oxygen species (ROS). According to recent studies, inhibition of NOX activity can reduce cognitive impairment in animal models of VaD. In this article, we review the evidence linking cognitive impairment with NOX-dependent OS, including the vascular NOX and non-vascular NOX systems, in VaD...

Alzheimer's disease (AD), characterized by the aggregation of amyloid-β (Aβ) protein and neuroinflammation, is the most common neurodegenerative disease globally. Previous studies have reported that some AD patients show impaired glucose utilization in brain, leading to cognitive decline. Recently, diabetes-induced dementia has been called "type 3 diabetes", based on features in common with those of type 2 diabetes and the progression of AD. Impaired glucose uptake and insulin resistance in the brain are important issues in type 3 diabetes, because these problems ultimately aggravate memory dysfunction in the brain...

Nowadays proper detection of cognitive impairment has become a challenge for the scientific community. Alzheimer's Disease (AD), the most common cause of dementia, has a high prevalence that is increasing at a fast pace towards epidemic level. In the not-so-distant future this fact could have a dramatic social and economic impact. In this scenario, an early and accurate diagnosis of AD could help to decrease its effects on patients, relatives and society. Over the last decades there have been useful advances not only in classic assessment techniques, but also in novel non-invasive screening methodologies...

BACKGROUND: Great effort has been put into developing simple and feasible tools capable to detect Alzheimer's disease (AD) in its early clinical stage. Spatial navigation impairment occurs very early in AD and is detectable even in the stage of mild cognitive impairment (MCI). OBJECTIVE: The aim was to describe the frequency of self-reported spatial navigation complaints in patients with subjective cognitive decline (SCD), amnestic and non-amnestic MCI (aMCI, naMCI) and AD dementia and to assess whether a simple questionnaire based on these complaints may be used to detect early AD...

OBJECTIVE: This study presents a novel approach for early detection of cognitive impairment in the elderly. The approach incorporates the use of speech sound analysis, multivariate statistics, and data-mining techniques. We have developed a speech prosody-based cognitive impairment rating (SPCIR) that can distinguish between cognitively normal controls and elderly people with mild Alzheimer's disease (mAD) or mild cognitive impairment (MCI) using prosodic signals extracted from elderly speech while administering a questionnaire...

Dysregulated pathway identification is an important task which can gain insight into the underlying biological processes of disease. Current pathway-identification methods focus on a set of co-expression genes and single pathways and ignore the correlation between genes and pathways. The method proposed in this study, takes into account the internal correlations not only between genes but also pathways to identifying dysregulated pathways related to Alzheimer's disease (AD), the most common form of dementia...

Over a third of community-residing elderly have clinical gait abnormalities, and gait impairment is associated with morbidity, mortality and dementia. Motor imagery - envisioning motor actions without actual execution - has been used to improve gait in Parkinson's disease and poststroke, but the efficacy of motor imagery in healthy elderly is unknown. This single-blind pilot randomized-controlled trial aims to establish feasibility and explore the efficacy of a 3-month, telephone-based motor imagery intervention - that involves imagined walking, imagined talking and imagined walking while talking for improving gait in 48 healthy elderly...

There are an increasing number of people living with dementia in care home settings. Recent reports suggest that people who deliver care to residents living with dementia in care homes require specialist support to provide optimum care. To address this need Four Seasons Health Care, the largest provider of care homes within the UK today, sought to design a dementia care framework that enhanced the quality of life for people living with dementia in their care homes. The framework was designed using a robust evidence base, engagement with people living with dementia, their care partners, policy-writers, multidisciplinary professionals and people within the organisation...

Background People in the early stages of dementia adjust to the illness through stages of awareness, coping, and evaluation. Studies have found that hope, social support, and self-esteem facilitate coping, adjustment, and adaptation in chronic illness. Objective The purpose of this descriptive study was to examine the relationships between hope, social support, and self-esteem in individuals with early stage dementia. Methods Data were obtained from 53 individuals with early stage dementia. The scores on the Herth Hope Index, Social Support Questionnaire Short-Form, and the State Self-Esteem Scale were analyzed using linear regression...

BACKGROUND: (18)F-florbetapir uptake by brain tissue measured by positron emission tomography (PET) is accepted by regulatory agencies like the Food and Drug Administration (FDA) and the European Medicine Agencies (EMA) for assessing amyloid load in people with dementia. Its added value is mainly demonstrated by excluding Alzheimer's pathology in an established dementia diagnosis. However, the National Institute on Aging and Alzheimer's Association (NIA-AA) revised the diagnostic criteria for Alzheimer's disease and confidence in the diagnosis of mild cognitive impairment (MCI) due to Alzheimer's disease may be increased when using amyloid biomarkers tests like (18)F-florbetapir...

PURPOSE OF REVIEW: HIV-associated neurocognitive disorders (HAND) are common in patients with HIV disease, even during suppressive combination antiretroviral therapy (cART). This review article addresses the pathogenesis of HAND, focusing on important findings from the last 5 years. RECENT FINDINGS: While HIV-associated dementia is now rare in settings with cART availability, mild forms of HAND are increasing in prevalence. Biomarkers of cellular injury, such as neurofilament light chain and neopterin, can detect early stages of neuroinflammation associated with HIV infection and are increased even in asymptomatic individuals with chronic HIV infection...

The second-to-fourth finger length ratio (2D:4D) is an indication of prenatal sex hormone exposure, and has sex-specifically been associated with several lethal illnesses including ischemic heart disease, diverse cancers, and suicide. Our primary aim was to verify that 2D:4D sex-specifically relates to life expectancy and suicide numbers on a national level (23 countries). We also used a hypothesis-free approach to investigate associations with other causes of death [p value adjustment for multiple hypothesis testing using the false discovery rate procedure (FDR)]...
