BACKGROUND/OBJECTIVES: Behavioral problems in individuals with Alzheimer's disease (AD) impose major management challenges. Current prevention strategies are anchored to cognitive outcomes, but behavioral outcomes may provide another, clinically relevant opportunity for preemptive therapy. We sought to determine whether personality changes that predispose to behavioral disorders arise during the transition from preclinical AD to mild cognitive impairment (MCI). DESIGN: Longitudinal observational cohort study...

Importance: Late-onset Alzheimer disease (AD) is highly heritable. Genome-wide association studies have identified more than 20 AD risk genes. The precise mechanism through which many of these genes are associated with AD remains unknown. Objective: To investigate the association of the top 20 AD risk variants with brain amyloidosis. Design, Setting, and Participants: This study analyzed the genetic and florbetapir F 18 data from 322 cognitively normal control individuals, 496 individuals with mild cognitive impairment, and 159 individuals with AD dementia who had genome-wide association studies and 18F-florbetapir positron emission tomographic data from the Alzheimer's Disease Neuroimaging Initiative (ADNI), a prospective, observational, multisite tertiary center clinical and biomarker study...

Clinical diagnosis of progressive supranuclear palsy (PSP) is sometimes difficult because various phenotypes have been identified. Here, we report a mutation in the bassoon (BSN) gene in a family with PSP-like syndrome. Their clinical features resembled not only those of PSP patients but also those of individuals with multiple system atrophy and Alzheimer's disease. The neuropathological findings showed a novel three + four repeat tauopathy with pallido-luysio-nigral degeneration and hippocampal sclerosis...

Age is the greatest risk factor for Alzheimer's disease, the most common cause of dementia. The older population in the United States is growing, and within this demographic ethnic and racial diversity is also on the rise. This article introduces Stanford Health Care's Memory Support Program (MSP) as a model for culturally competent dementia care that spans inpatient and outpatient settings. The case study of an African American patient and family dealing with an Alzheimer's disease diagnosis and comorbid conditions is presented and explored to illustrate the MSP model...

Globally, there is an increase in the older population, whose lives are affected by local cultural norms. In Eastern Mediterranean countries, dementia is conventionally hidden from view with few dedicated services or recognition for diagnosis. The aim of this systematic review is to explore the limited literature on dementia and cognitive impairment among older people in Eastern Mediterranean countries to present an evaluation of current practices and to consolidate knowledge for future planning. Thirty-three studies were identified for inclusion in the review, and four themes were apparent...

AIM: The aim of the present study was to develop a way of identifying dementia using clinical assessments made by primary care physicians under the existing medical care system in Japan. METHODS: A total of 623 people aged ≥65 years underwent standard clinical assessments by primary care physicians under the long-term-care insurance program to determine their grade of activities of daily living related to dementia. To examine the validity of the diagnosis, neuropsychiatrists carried out further diagnosis of dementia for all the participants...

BACKGROUND: Subjective cognitive complaints are commonly encountered in primary care and often result in memory clinic referral. However, meta-analyses have shown that such concerns do not consistently correspond to objective memory impairment or predict future dementia. Memory clinic referrals are increasing, with greater proportions of patients attending who do not have dementia. Studies of interaction during memory clinic assessments have identified conversational profiles that can differentiate between dementia and functional disorders of memory...

BACKGROUND: Amyloid-β positron emission tomography (PET) allows for in vivo detection of fibrillar amyloid plaques, a pathologic hallmark of Alzheimer's disease (AD). However, amyloid-β PET interpretation is limited by the imperfect correlation between PET and autopsy, and the fact that it is positive in about 20% to 30% of cognitively normal individuals and non-AD dementias, especially when older or carrying the ε4 allele of apolipoprotein E (ApoE4). When facing a positive amyloid PET, clinicians have to evaluate the probability of a pathologic false positive as well as the probability of amyloid positivity being age-related, comorbid to a primary non-AD dementia (clinicopathologic false positive)...

Amee Baird, William Forde Thompson
In this review, we consider how the onset and progression of dementia can disrupt one's sense of self, and propose that music is an ideal tool for alleviating this distressing symptom. Various aspects of the self can be impaired in people with dementia, depending on how the self is defined. There are anecdotal reports that music can 'bring people back to themselves' in the face of dementia, but there have been scarce empirical investigations of this topic. Motivated by a consideration of the existing literature, we outline a novel theoretical framework that accounts for the relationship between music and the self in people with dementia...

Background Thorough dental prevention provided at the diagnosis of early stage dementia may be able to reduce the risk of dental disease before the associated cognitive decline takes hold.Method A questionnaire was used to see how many patients with a recent diagnosis of dementia were registered with a dentist and if they were accessing preventative dental care. The questionnaire was administered to patients attending Memory Assessment Services (MAS), approximately ten weeks after initial diagnosis. A similar questionnaire was conducted among MAS staff providing insight into their own personal dental care knowledge and behaviours...

Neurogenetic diseases are surprisingly common. This chapter reviews a systematic approach to the evaluation of a patient thought to have such a disease. The emphasis is on first recognizing potential clues to the diagnosis contained in the family history and presentation of symptoms. Ataxia, neuropathy, muscle weakness, dementia, epilepsy, and cognitive delay are all "reservoirs" of neurogenetic disease. A high index of suspicion for genetic causes and a thoughtful evaluation of simplex (sporadic) cases is often necessary...

OBJECTIVE: Nowadays, there is a rapid increase of neurocognitive disorders (ND), while Alzheimer disease (AD), is the most frequent type of neurodegeneration. Therefore, Day Care Centers (DCC) and Memory Clinics (MC) have been created in order to correspond to the rising needs of people with ND. The aim of the study was to record clinical and demographic characteristics of people with ND from the broader area of Thessaloniki. SUBJECTS AND METHODS: Data bases were collected and were analyzed in order to examine demographical characteristics of all visitors of the DCC of Alzheimer Hellas and of visitors of the Papanikolaou General Hospital, during the years 2007-2017...

OBJECTIVE: The role of ventriculomegaly and its interplay between various dementia entities and their pathogenesis, as well as its correlation to the levels of CSF protein markers, remains to be elucidated. Evans index (EI) is a well-established radiological marker in the diagnosis of idiopathic Normal Pressure Hydrocephalus (iNPH), assessing ventricular enlargement. However, there are no previous studies investigating the correlation between EI, age, beta amyloid (Aβ), tau and phosphorylated-tau (p-tau) proteins in the CSF...

BACKGROUND: The term "Subjective Cognitive Impairment (SCI)" is the most widely accepted term for cognitive complaints of otherwise apparently healthy older adults. It is presently clear that SCI might be a risk factor for the development of Mild Cognitive Impairment and dementia. As regards SCI measurement and potential diagnosis, several studies showed that SCI is a condition in which people score in the normal range on common tests but believe they experience cognitive decline. Hence, to assess the characteristic of the SCI subtle cognitive decline, self-report measures were developed to estimate "self-experience" of minimal decline in cognition seem the most appropriate tools...

BACKGROUND: Differential diagnosis between dementia with Lewy bodies (DLB) and Alzheimer's disease (AD) is not straightforward, especially in the early stages of disease. We compared AD biomarkers (phospho-Tau181, total-Tau, Aβ42 and Aβ40) in cerebrospinal fluid (CSF) of patients with DLB and AD, focusing especially on the prodromal stage. METHODS: A total of 1221 CSF were collected in different memory centres (ePLM network) in France and analysed retrospectively...

BACKGROUND: Few patients with a normal cerebrospinal fluid (CSF) biomarker profile fulfill the clinical criteria for Alzheimer disease (AD). OBJECTIVE: The aim of this study was to test the hypothesis of misdiagnoses for these patients. METHOD: Patients from the e-PLM centers fulfilling the core clinical criteria for probable AD dementia or mild cognitive impairment due to AD (AD-MCI), with normal CSF A1-42, T-tau and P-tau biomarkers and clinical follow-up, were included...
