NOTCH2NLC Repeat Expansions in Parkinsonian Disorders: Clinical and Neuroimaging Characteristics

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neuronal intranuclear inclusion disease (NIID) is a neurodegenerative disorder caused by NOTCH2NLC GGC repeat expansions, with heterogeneous clinical manifestations, including parkinsonism. Recent studies have identified NOTCH2NLC repeat expansions in patients with Parkinson's disease (PD) and atypical parkinsonism (aPM), suggesting ...

Cardiovascular autonomic function and MCI in Parkinson's disease [PDF]

open access: yes, 2019
Introduction: dysautonomic dysfunction and cognitive impairment represent the most disabling non-motor features of Parkinson's Disease (PD). Recent evidences suggest the association between Orthostatic Hypotension (OH) and PD-Dementia. However, little is
