TL;DR: Frontotemporal lobar degeneration, corticobasal degeneration (CBD), and progressive supranuclear palsy (PSP) have overlapping clinical features, and the prediction of tau-positive pathology from a CBD or PSP-like presentation is good, while the frontotem temporal dementia (FTD)-motor neuron disease syndrome almost certainly predicts motor neuron degeneration.

TL;DR: A syndrome characterized by progressive pure apraxia of speech clearly exists, with a neuroanatomic correlate of superior lateral premotor and supplementary motor atrophy, making this syndrome distinct from primary progressive aphasia.

TL;DR: Findings suggest that late-life-onset depression may be associated with an increased severity of subcortical vascular disease and greater impairment of cognitive performance.

TL;DR: The authors describe the major types of acoustic analysis available for the study of speech, specify the components needed for a modern speech analysis laboratory, including equipment for recording and analysis, and list possible measurements for various aspects of phonation, articulation and resonance, as they might be manifest in neurologically disordered speech.

TL;DR: Apathy occurs frequently in neuropsychiatric disorders both as a symptom of other syndromes and as a syndrome per se as mentioned in this paper, and apathy is a discriminable dimension of behavior having its own pathophysiology and implications for psychiatric care.
