Neuroimaging, both with magnetic resonance imaging (MRI) and positron emission tomography (PET), has gained a pivotal role in the diagnosis of primary neurodegenerative diseases. These two techniques are used as biomarkers of both pathology and progression of Alzheimer's disease (AD) and to differentiate AD from other neurodegenerative diseases. MRI is able to identify structural changes including patterns of atrophy characterizing neurodegenerative diseases, and to distinguish these from other causes of cognitive impairment, e...

Alzheimer's disease (AD) is the most common form of dementia and is characterized by impairment in memory, behavioral changes, and gradual loss of autonomy. Since there is a long latent period prior to diagnosis, the aim of this study was to determine whether twenty single nucleotide polymorphisms identified in genome-wide association analyses of AD are associated with cognitive change in 8,320 white and 2,039 African-American middle-aged adults enrolled in the prospective Atherosclerosis Risk in Communities (ARIC) study...

INTRODUCTION: Periodontal disease and dementia are very prevalent, especially in elderly populations. Multiple studies have shown a link between these diseases; however, the conditions are highly heterogeneous and so is the diagnostic methodology, which may hinder interpretation and comparison of the results. The aim of this article is to provide a critical review of the literature linking these 2 processes. DEVELOPMENT: We retrieved 22 studies, most of which were retrospective, and analysed various methodological variables including study population, diagnosis of periodontitis, definition of dementia, adjusted variables, and results...

As well known, the increase in life expectancy and the better physical condition of people in western countries will lead in the next 20 years to a dramatic development of neurodegenerative diseases, especially of dementia that could be considered one of the most important problems in clinical, social and economic fields for the future. Therefore, the differential diagnosis of the various types of dementia is a critical step for patients, clinicians and researchers since an accurate "in vivo" diagnosis can lead to a better patients management...

Frontotemporal degeneration (FTD) in its behavioral variant (bvFTD) is probably one of the conditions that best illustrates the links between psychiatry and neurology. It is indeed admitted that between a third and half of patients with this condition, especially in early-onset forms, receive an initial diagnosis of psychiatric disorder (depression, schizophrenia, bipolar disorder) and are then referred to a psychiatric ward. BvFTD can thus be considered a neurological disorder with a psychiatric presentation...

OBJECTIVE: Efficient detection of neurocognitive disorders is a key diagnostic challenge. We explored how simple bedside tests of attention, vigilance and visuospatial function might assist in identifying delirium in hospitalized patients. METHODS: Performance on a battery of bedside cognitive tests was compared in elderly medical inpatients with DSM-IV delirium, dementia, comorbid delirium-dementia, and no neurocognitive disorder. RESULTS: 193 patients [mean age 79...

Contemporary research into health and mental health treats diagnosis as a central step in understanding illness management and trajectory; consequently, in the last two decades, sociology of diagnosis has attained increasing influence within medical sociology. Deeply embedded in social constructionism, the set of research divides between those who focus on the social and historical construction of diagnoses as categories, and those who see diagnosis as a process. Regarding the latter, this approach explores the constitution of the medical production, highlighting how it constitutes a starting point for entering a 'sick role', for being labelled, for naming one's problem and by extension, for framing one's illness narrative...

This protocol describes the administration of the 4 Mountains Test (4MT), a short test of spatial memory, in which memory for the topographical layout of four mountains within a computer-generated landscape is tested using a delayed match-to-sample paradigm. Allocentric spatial memory is assessed by altering the viewpoint, colors and textures between the initially presented and target images. Allocentric spatial memory is a key function of the hippocampus, one of the earliest brain regions to be affected in Alzheimer's disease (AD) and impairment of hippocampal function predates the onset of dementia...

OBJECTIVE: To measure the diagnostic accuracy of the 4A's test in screening for delirium in geriatric inpatients from culturally diverse backgrounds. METHODS: A prospective study was conducted with patients admitted to the geriatric and orthogeriatric services of a tertiary teaching hospital. Consenting participants aged 65 years and over were screened for delirium with the 4AT by nursing staff within 72 h of admission. The diagnosis of delirium was made separately by expert assessors, responsible for the participant's clinical care, blinded to the 4AT score, within 30 min of the 4AT assessment using the DSM 5 criteria and the Confusion Assessment Method...

Most people with mild dementia can continue to drive, but dementia is progressive and many patients and clinicians will be faced with questions about driving safety in the course of their illness. Determining when this happens is a complex decision, with risks of personal and public safety needing to be weighed against individual patient benefits of driving in terms of autonomy, independence and well-being. Decisions need to make reference to cognitive abilities, as well as other factors including physical comorbidity, vision, mobility, insight and history of driving errors and accidents...

BACKGROUND The demand for critical care services among elderly with dementia outpaces that of their non-dementia elderly counterparts. However, there are scarce data on the corresponding attributes among ICU-managed patients with dementia. MATERIAL AND METHODS We used the Texas Inpatient Public Use Data File to examine temporal trends of the demographics, burden of comorbidities, measures of severity of illness, use of healthcare resources, and short-term outcomes among hospitalizations aged 65 years or older with a reported diagnosis of dementia, who were admitted to ICU (D-ICU hospitalizations) between 2001 and 2010...

Fahr's disease or Fahr's syndrome is a rare neurodegenerative disorder characterized by abnormal symmetrical calcifications of the basal ganglia, thalami, sub-cortical hemispheric white matter and deep cerebellar nuclei. It can be idiopathic or associated with an endocrinopathy, frequently with parathyroid disorder. Clinical spectrum of the disease is wide ranging from neurological features like seizure, syncope, stroke like events, extra-pyramidal symptoms often combined with frontal sub-cortical pattern of behavioural dysfunction and psychiatric symptoms such as psychosis, mood disorder and dementia...

It is recognized that neuropsychiatric conditions are over-represented in ALS patient kindreds and psychiatric symptoms may precede the onset of motor symptoms. Using a hospital record linkage database, hospitalization with a diagnosis of schizophrenia, bipolar disorder, depression or anxiety was significantly associated with a first diagnosis of ALS within the following year. This is likely to specifically reflect the clinicopathological overlap of ALS with frontotemporal dementia. A diagnosis of depression was significantly associated with a first record of ALS five or more years later, in keeping with growing evidence for major depressive disorder as an early marker of cerebral neurodegeneration...

CONTEXT AND OBJECTIVE: A search in the SciELO and PubMed databases showed few studies on human immunodeficiency virus (HIV) positive individuals in long-term care institutions (LTCIs), thus prompting the present study. The aim of this study was to ascertain whether there were any HIV-positive individuals in LTCIs for the elderly. DESIGN AND SETTING: Cross-sectional study in which the Hospital Infection Control Committee (HICC) of a 405-bed LTCI was consulted. METHODS: The medical records of 405 individuals interned in the LTCI who had been tested for HIV infection were requested for analysis of the following variables: [1] age and gender; [2] length of stay at LTCI (months); [3] causes and diagnoses on admission to LTCI according to International Classification of Diseases, 10th edition; [4] date of HIV diagnosis; [5] seropositivity for syphilis and hepatitis B and C viruses; [6] medications used at last prescription in medical file; and [7] mean CD4 lymphocyte count based on: total lymphocyte count/6 and total lymphocyte count x 0...

The goal of this study was to estimate the rate of the progression of mild cognitive impairment to dementia and identify the potential risk factors in German specialist practices from 2005 to 2015. This study included 4633 patients aged 40 years and over from 203 neuropsychiatric practices, who were initially diagnosed with mild cognitive impairment between 2005 and 2013. The primary outcome was diagnosis of all-cause dementia recorded in the database until the end of the five-year follow-up period. Cox regression models were used to examine mild cognitive impairment progression to dementia when adjusted for confounders (age, sex, and health-insurance type)...
