TL;DR: Consensus criteria for the three prototypic syndromes-frontotemporal dementia, progressive nonfluent aphasia, and semantic dementia-were developed by members of an international workshop on frontotem temporal lobar degeneration and ought to provide the foundation for research work into the neuropsychology, neuropathology, genetics, molecular biology, and epidemiology of these important clinical disorders.

TL;DR: The revised criteria for behavioural variant frontotemporal dementia improve diagnostic accuracy compared with previously established criteria in a sample with known frontotmporal lobar degeneration and reflect the optimized diagnostic features, less restrictive exclusion features and a flexible structure that accommodates different initial clinical presentations.

TL;DR: The bilinguals showed symptoms of dementia 4 years later than monolinguals, and the rate of decline in Mini-Mental State Examination scores over the 4 years subsequent to the diagnosis was the same for a subset of patients in the two groups, suggesting a shift in onset age with no change in rate of progression.

TL;DR: Recommendations arising from an international research workshop on frontotemporal dementia (FTD) and ALS address the requirement for a concise clinical diagnosis of the underlying motor neuron disease, defining the cognitive and behavioural dysfunction, and identifying the presence of disease modifiers.

TL;DR: It is concluded that lifelong bilingualism confers protection against the onset of AD, and the effect does not appear to be attributable to such possible confounding factors as education, occupational status, or immigration.
