Olfactory function in essential tremor.

TL;DR: Severe deficits were found for both patients with AD and PD in each of the 3 olfactory domains relative to controls, however, no discriminating Olfactory deficits were seen between patient groups or among the 3 measured olf factory domains, suggesting a similar disturbance in olfaction function between patients withAD and PD.

TL;DR: The limited data available suggest that the physiological determinants of the early changes in PD-related olfactory function are likely multifactorial and may include the same determinants as those responsible for a number of other non-motor symptoms of PD, such as dysautonomia and sleep disturbances.

TL;DR: A protective association of cigarette smoking for Parkinson's disease may constitute an important etiologic clue.

TL;DR: Current knowledge and future prospects of weight loss and malnutrition in the context of PD are presented to appeal clinicians and researchers to pay a closer attention to this phenomena and enable better management and therapeutic strategies in future clinical practice.

TL;DR: The lack of relevant differences between ET subgroups suggests that, despite variable expression, ET represents a single disease entity.

TL;DR: This study suggests that some patients with essential tremor have genetically increased risk for Parkinson's disease, and these patients are likely to be at increased risk of developing PD.

TL;DR: Clinical and neuropathologic studies of six additional patients with essential tremor found no abnormalities of the substantia nigra consistent with Parkinson's disease and the Neuropathologic substrate of ET remains unknown.
