Importance: Depression is common in individuals with mild cognitive impairment (MCI) and may confer a higher likelihood of progression to dementia. Prevalence estimates of depression in those with MCI are required to guide both clinical decisions and public health policy, but published results are variable and lack precision. Objective: To provide a precise estimate of the prevalence of depression in individuals with MCI and identify reasons for heterogeneity in the reported results...

INTRODUCTION: The prevalence of dementia is increasing without a known cure, resulting in an increasing number of informal caregivers. Caring for a person with dementia results in increased stress and depressive symptoms. There are several behavioural interventions designed to alleviate stress and depressive symptoms in caregivers of persons with dementia with evidence of efficacy. Two of the best-known interventions are the New York University Caregiver Intervention (NYUCI) and the Resources for Enhancing Alzheimer's Caregivers Health (REACH)...

Lymphomatosis cerebri (LC) is a rare variant of a primary central nervous system non-Hodgkin's lymphoma (PCNSL) characterised by diffuse infiltration of tumour cells throughout the brain parenchyma. We present a 68-year-old immunocompetent woman with headaches, dizziness, blurred vision, localised right leg weakness and rapidly progressive dementia. A brain MRI demonstrated diffuse T2 hyperintense white matter lesions that did not enhance with contrast. The clinical differential diagnosis of these lesions included metastatic disease, infectious or inflammatory process such as sarcoidosis, lymphoma, demyelinating disease and less likely vascular aetiology, such as vasculitis or ischaemic stroke...

OBJECTIVE: To determine the prevalence of autoimmune disease in symptomatic C9ORF72 (C9) mutation carriers and frontotemporal dementia with motor neuron disease (FTD/MND) cohorts. METHODS: In this case-control study, we reviewed the clinical histories of 66 patients with FTD/MND and 57 symptomatic C9 carriers (24 overlapping cases), a total of 99 charts, for history of autoimmune disease. The prevalence of autoimmune disease in C9 and FTD/MND cohorts was determined by χ(2) and Fisher exact comparisons between the combined C9 and FTD/MND group with normal control, Alzheimer disease, and progressive supranuclear palsy cohorts, as well as comparisons within C9 and FTD/MND cohorts...

Bipolar disorder (BD) could represent a prodromal state of frontotemporal dementia (FTD). Two patients affected by lifelong BD with a progressive decline of cognitive functions, behavioral, and neurological signs, reached the early diagnosis of FTD before the age of 60. They were diagnosed as affected by primary progressive aphasia and FTD with parkinsonism, respectively. A diagnosis of FTD should therefore be taken into account, in case of unexpected cognitive and behavioral decline in patients with a long history of BD...

BACKGROUND: Deficits in mitochondrial function and oxidative stress play pivotal roles in Down syndrome (DS) and Alzheimer's disease (AD) and these alterations in mitochondria occur systemically in both conditions. OBJECTIVE: We hypothesized that peripheral cells of elder subjects with DS exhibit disease-specific and dementia-specific metabolic features. To test this, we performed a comprehensive analysis of energy metabolism in lymphoblastic-cell-lines (LCLs) derived from subjects belonging to four groups: DS-with-dementia (DSAD), DS-without-dementia (DS), sporadic AD, and age-matched controls...

BACKGROUND: The [(18) F]AV-1451 positron emission tomography ligand allows the in vivo assessment of tau proteins in the brain. It shows strong binding in Alzheimer's dementia, but little is known about how it performs in progressive supranuclear palsy, a primary 4R tauopathy. OBJECTIVES: The objectives of this study were to determine whether [(18) F]AV-1451 uptake can be observed in progressive supranuclear palsy and to characterize the regional distribution when compared with controls and Alzheimer's dementia...

BACKGROUND: The early and mild phases of various neurodegenerative diseases, sometimes described as mild cognitive impairment (MCI), has been characterized as the transitional state between normal cognition and dementia. It is described as having cognitive decline not severe enough to cause functional impairment. MCI has been divided into amnestic and non-amnestic subtypes with the amnestic subtype most commonly progressing to AD. The MCI phase of other dementias such as DLB has also been described...

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...

OBJECTIVE: Cortical thinning, previously identified during prodromal stages of Alzheimer's disease (AD), is a "candidate" biomarker implemented in AD clinical therapy trials. We investigated the effect of donepezil treatment on cortical thickness in mild cognitively impaired subjects with the amnestic syndrome of the hippocampal type, a prodromal at-risk group for progression to AD dementia. METHODS: Data were from a longitudinal analysis of a community-based multicenter suspected prodromal AD cohort diagnosed by the Free and Cued Selective Reminding Test (81 donepezil vs 92 placebo) enrolled in a double-blind, randomized, placebo-controlled parallel group design using donepezil (10 mg/day)...

Given the multifaceted nature of dementia care management, an interdisciplinary comprehensive clinical approach is necessary. We describe our one-year experience with outpatient based dementia care at the Montefiore-Einstein Center for the Aging Brain (CAB) involving an multispecialty team of geriatricians, neurologists, and neuropsychologists, supported by geriatric psychiatrists, physiatrists, and social services. The goals of the CAB is to maximize dementia outcomes, including regular monitoring of patient's health and cognition, education and support to patients, their families and caregivers; initiation of pharmacological and non-pharmacological treatments as appropriate, and the facilitation of access to clinical trials...

Originally, the middle longitudinal fascicle (MdLF) was defined as a long association fiber tract connecting the superior temporal gyrus and temporal pole with the angular gyrus. More recently its description has been expanded to include all long postrolandic cortico-cortical association connections of the superior temporal gyrus and dorsal temporal pole with the parietal and occipital lobes. Despite its location and size, which makes MdLF one of the most prominent cerebral association fiber tracts, its discovery in humans is recent...

BACKGROUND AND OBJECTIVE: Primary progressive aphasia (PPA) is a clinical syndrome due to different neurodegenerative conditions in which an accurate early diagnosis needs to be supported by a reliable diagnostic tool at the individual level. In this study, we investigated in PPA the FDG-PET brain metabolic patterns at the single-subject level, in order to assess the case-to-case variability and its relationship with clinical-neuropsychological findings.
