INTRODUCTION: Semantic dementia, including the semantic variant of primary progressive aphasia (svPPA), is strongly associated with TAR-DNA binding protein 43 (TDP-43) type C pathology. It provides a useful model in which to test the specificity of in vivo binding of the putative tau ligand [(18)F]AV-1451, which is elevated in frontotemporal lobar degeneration tauopathies. METHODS AND RESULTS: Seven patients (five with svPPA and two with 'right' semantic dementia) and 12 healthy controls underwent positron emission tomography brain imaging with [(18)F]AV-1451...

Rationale The pathophysiology of most lacunar stroke, a form of small vessel disease, is thought to differ from large artery atherothrombo- or cardio-embolic stroke. Licensed drugs, isosorbide mononitrate and cilostazol, have promising mechanisms of action to support their testing to prevent stroke recurrence, cognitive impairment, or radiological progression after lacunar stroke. Aim LACI-1 will assess the tolerability, safety, and efficacy, by dose, of isosorbide mononitrate and cilostazol, alone and in combination, in patients with ischemic lacunar stroke...

Argyrophilic grain disease (AGD) is a common four-repeat tauopathy in elderly people. While dementia is a major clinical picture of AGD, recent studies support the possibility that AGD may be a pathological base in some patients with mild cognitive impairment, late-onset psychosis, bipolar disorder and depression. AGD often coexists with various other degenerative changes. The frequency of AGD in progressive supranuclear palsy (PSP) cases was reported to range from 18.8% to 80%. The frequency of AGD in corticobasal degeneration (CBD) cases tends to be higher than that in PSP cases, ranging from 41...

Due to the progressive aging of the population, Alzheimer's disease (AD) is becoming a healthcare burden of epidemic proportions for which there is currently no cure. Disappointing results from clinical trials performed in mild-moderate AD dementia combined with clear epidemiological evidence on AD risk factors are contributing to the development of primary prevention initiatives. In addition, the characterization of the long asymptomatic stage of AD is allowing the development of intervention studies and secondary prevention programmes on asymptomatic at-risk individuals, before substantial irreversible neuronal dysfunction and loss have occurred, an approach that emerges as highly relevant...

BACKGROUND: The use of imaging markers for the diagnosis of predementia and early dementia stages of Alzheimer's disease (AD) has widely been explored in research settings and specialized care. The use of these markers in primary care has yet to be established. OBJECTIVE: Summarize current evidence for the usefulness of imaging markers for AD in primary compared to specialized care settings. METHOD: Selective overview of the literature, and pilot data on the use of MRI-based hippocampus and basal forebrain volumetry for the discrimination of AD dementia and mild cognitive impairment (MCI) cases from healthy controls in 58 cases from a primary care cohort and 58 matched cases from a memory clinic's sample...

Non-cognitive features including personality changes are increasingly recognized in the three PPA variants (semantic-svPPA, non fluent-nfvPPA, and logopenic-lvPPA). However, differences in emotion processing among the PPA variants and its association with white matter tracts are unknown. We compared emotion detection across the three PPA variants and healthy controls (HC), and related them to white matter tract integrity and cortical degeneration. Personality traits in the PPA group were also examined in relation to white matter tracts...

Frontotemporal lobar dementia (FTLD) is a heterogeneous group of neurodegenerative diseases. FTLD encompass: 1) behavioral forms, sometimes associated with amyotrophic lateral sclerosis; 2) linguistic forms (semantic and non-fluent primary progressive aphasia); 3) atypical parkinsonian syndromes (progressive supranuclear palsy and corticobasal syndrome). Standard brain MRI allows for strengthening the clinical suspicion of FTLD, by showing a pattern of atrophy in relation with the patient's clinical symptoms: frontotemporal anterior atrophy in behavioral forms; temporopolar or inferior left frontal atrophy in the linguistic forms; mesencephalic or corticosubcortical hemispheric atrophy in forms with atypical pakinsonism...

DL-3-n-butylphthalide (DL-NBP) is one of the constituents of Chinese celery extract that is used to treat stroke, dementia, and ischemic diseases. However, its role in traumatic brain injury is less well known. In this investigation, neuroprotective effects of DL-NBP in concussive head injury (CHI) on brain pathology were explored in a rat model. CHI was inflicted in anesthetized rats by dropping a weight of 114.6 g from a height of 20 cm through a guide tube on the exposed right parietal bone inducing an impact of 0...

Patients with non-fluent aphasias display impairments of expressive and receptive grammar. This has been attributed to deficits in processing configurational and hierarchical sequencing relationships. This hypothesis had not been formally tested. It was also controversial whether impairments are specific to language, or reflect domain general deficits in processing structured auditory sequences. Here we used an artificial grammar learning paradigm to compare the abilities of controls to participants with agrammatic aphasia of two different aetiologies: stroke and frontotemporal dementia...

β-Methylamino-L-alanine (BMAA) is implicated in neurodegeneration and neurotoxicity, particularly in ALS-Parkinson Dementia Complex. Neurotoxic properties of BMAA have been partly elucidated, while its transcellular spreading capacity has not been examined. Using reconstructed neuronal networks in microfluidic chips, separating neuronal cells into two subcompartments-(1) the proximal, containing first-order neuronal soma and dendrites, and (2) a distal compartment, containing either only axons originating from first-order neurons or second-order striatal neurons-creates a cortico-striatal network...

BACKGROUND AND PURPOSE: Brain iron deposition has been implicated as a major culprit in the pathophysiology of neurodegeneration. However, the quantitative assessment of iron in behavioral variant frontotemporal dementia and primary progressive aphasia brains has not been performed, to our knowledge. The aim of our study was to investigate the characteristic iron levels in the frontotemporal dementia subtypes using susceptibility-weighted imaging and report its association with behavioral profiles...

Subcortical ischemic vascular cognitive impairment (SIVCI) is the most preventable form of cognitive dysfunction. There is converging evidence from animal and human studies that indicate vascular injury as the primary cause of SIVCI. Currently, there are no curative pharmaceutical treatments for vascular dementia; however, exercise may be a promising strategy to combat SIVCI. This review will focus on the role of exercise as a strategy to prevent or slow the progression of SIVCI, with particular emphasis on the mechanisms by which exercise may improve cerebrovascular function...

Neurologic complications in persons with HIV infection are less severe in the era of potent antiretroviral therapy but remain highly prevalent. Prior to the use of antiretroviral therapy, opportunistic infections of the central nervous system (CNS) and CNS malignancy were common. Progressive multifocal leukoencephalopathy (PML), however, remains a diagnostic challenge in HIV-infected individuals, and no effective antiviral treatment for PML is currently available. Primary neurologic complications of acute HIV infection include aseptic meningitis and acute inflammatory demyelinating polyneuropathy...

The differential diagnosis of atypical parkinsonian syndromes is challenging. These severe and often rapidly progressive neurodegenerative disorders are clinically heterogeneous and show significant phenotypic overlap. Here we review clinical, imaging, neuropathologic and genetic features of multiple system atrophy (MSA), progressive supranuclear palsy (PSP), corticobasal degeneration (CBD), and frontotemporal lobar degeneration (FTLD). The terms CBD and FTLD refer to pathologically confirmed cases of corticobasal syndrome (CBS) and frontotemporal dementia (FTD)...

We report on a 63-year old man suffering from rapid progressive dementia due to bilateral hippocampal primary CNS lymphoma. Early diagnosis especially in secondary dementia is essential because of potentially treatable aetiologies with regression of cognitive and behaviour abnormalities. Characteristic imaging findings especially in inflammatory and neoplastic lesions affecting the hippocampal structures are discussed.

Objectives To synthesise current research exploring the factors and interventions associated with the quality of life of people with dementia. Background Dementia is a progressive condition affecting an estimated 40 million people worldwide. The illness has a significant impact on the lives of the persons affected and their loved ones, and may thus impair the quality of life of both. As it progresses, dementia weakens the patients' ability to express their own views about their quality of life and the factors associated with it...

OBJECTIVE: Primary lateral sclerosis (PLS) is a rare form of motor neuron disease characterised by UMN degeneration leading to slowly progressive spasticity. Whether it is a separate disease or a subtype of ALS has been debated. In ALS comorbid frontotemporal dementia (FTD) is frequently seen (±15%). However, cognitive and behavioural changes are generally not considered to be a part of PLS. METHODS: To report the clinical findings and frequency of PLS patients that developed FTD in a referral-based cohort and provide an overview of the literature...
