Moyamoya Disease and the Risk of Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Moyamoya disease (MMD) is a rare cerebrovascular disorder characterized by the progressive narrowing of arteries at the base of the brain, forming abnormal collateral vascular networks. While vascular parkinsonism is noted in MMD, its link to Parkinson's disease (PD) has not been explored.

Amyotrophic Lateral Sclerosis Prevalence Projection in 2040: A Less Rare Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To project ALS prevalence across multiple countries through 2040, accounting for both population aging and increased survival. Methods Data from the Piemonte and Valle d'Aosta ALS register (PARALS) was used to estimate the trends in incidence and prevalence from 2005 to 2019. Survival trends over this period were also assessed.
