Abstract We performed a comprehensive cognitive, neuroimaging, and genetic study of 31 patients with primary progressive aphasia (PPA), decline in language functions that remains isolated for at least 2 years. Detailed speech evaluation was used to identify three different clinical variants: nonfluent (NFPA; n = 11), semantic dementia (SD; 10), third variant termed logopenic (LPA; 10). Voxel‐based morphometry (VBM) on MRIs showed that, when all PPA were analyzed together, the left...

Abstract Objective Frontotemporal lobar degeneration (FTLD) is characterized by impairments in social, behavioral, and/or language function, but postmortem studies indicate that multiple neuropathological entities lead to FTLD. This study assessed whether specific clinical features predict the underlying pathology. Methods A clinicopathological correlation was performed on 90 consecutive patients with a pathological diagnosis of frontotemporal dementia and compared an additional 24 cases...

<h3>Background</h3> Until recently, frontotemporal lobar degeneration (FTLD) was considered a rare neurodegenerative disorder that difficult to diagnose. The publication of consensus criteria for FTLD, however, prompted systematic studies. categorize FTLD into 3 subgroups: dementia, semantic and progressive nonfluent aphasia. <h3>Objective</h3> To compare demographic characteristics patients in the subgroups. <h3>Design</h3> We compared diagnostic breakdown, age at onset, sex, Mini-Mental...

Purpose of the Study: During aging, musical activities can help maintain physical and mental health cognitive abilities, but their rehabilitative use has not been systematically explored in persons with dementia (PWDs). Our aim was to determine efficacy a novel music intervention based on coaching caregivers PWDs either singing or listening regularly as part everyday care. Design Methods: Eighty-nine PWD–caregiver dyads were randomized 10-week group (n = 30), 29), usual care control 30). The...

Pedigrees from 269 patients with frontotemporal lobar degeneration (FTLD), including dementia (FTD), FTD ALS (FTD/ALS), progressive nonfluent aphasia, semantic (SD), corticobasal degeneration, and supranuclear palsy were analyzed to determine the degree of heritability these disorders. FTD/ALS was most SD least heritable subtype. FTLD syndromes appear have different etiologies recurrence risks.

<b>Background: </b> Frontotemporal lobar degeneration (FTLD) is a common cause of non-Alzheimer dementia, but its natural history and the factors related to mortality in affected patients are not well understood. <b>Methods: This retrospective, longitudinal study compared survival FTLD (n = 177) with Alzheimer disease (AD; n 395). Hazards analysis investigated contribution various demographic, neuropsychiatric, neuropsychological variables associated neurologic neuropathologic findings....

To better define the anatomic distinctions between Alzheimer's disease (AD) and frontotemporal lobar degeneration (FTLD), we retrospectively applied voxel-based morphometry to earliest magnetic resonance imaging scans of autopsy-proven AD (N = 11), FTLD 18), controls 40). Compared with controls, patients showed gray matter reductions in posterior temporoparietal occipital cortex; atrophy medial prefrontal temporal cortex, insula, hippocampus, amygdala; both disorders dorsolateral orbital...

Frontotemporal lobar degeneration (FTLD) often overlaps clinically with corticobasal syndrome (CBS) and progressive supranuclear palsy (PSP), both of which have prominent eye movement abnormalities. To investigate the ability oculomotor performance to differentiate between FTLD, Alzheimer's disease, CBS PSP, saccades smooth pursuit were measured in three FTLD subtypes, including 24 individuals frontotemporal dementia (FTD), 19 semantic (SD) six non-fluent aphasia (PA), as compared 28 15 CBS,...
