The family histories in the cases were remarkable with 10 of 16 patients reporting tremor or PD in at least 1 immediate family member. The authors suggested the term benign tremulous parkinsonism to be applied to this clinical constellation.

Alves et al² examined the relationship between motor subtypes and cognitive decline in PD. They prospectively followed a population-based cohort of 171 nondemented patients with PD for 8 years.
