Journal ArticleDOI
Patient-reported autonomic symptoms in Parkinson disease.
Dagmar Verbaan,Johan Marinus,Marianne de Visser,S M van Rooden,Anne M. Stiggelbout,J.J. van Hilten +5 more
TL;DR: Autonomic symptoms (AS) are an important feature of Parkinson disease (PD) and increase with age, disease severity, and medication use, which highlights the need for efficacious therapies for this domain of PD.
Journal ArticleDOI
Cognitive impairment in Parkinson’s disease
Dagmar Verbaan,Johan Marinus,Marianne de Visser,S M van Rooden,Anne M. Stiggelbout,Huub A. M. Middelkoop,J.J. van Hilten +6 more
TL;DR: Cognitive functioning is an important domain of the clinical spectrum of PD and poorer cognitive performance is associated with greater impairment in motor and non-motor domains in PD.
Journal ArticleDOI
The identification of Parkinson's disease subtypes using cluster analysis: a systematic review.
Stephanie M. van Rooden,Willem J. Heiser,Joost N. Kok,Joost N. Kok,Dagmar Verbaan,Jacobus J. van Hilten,Johan Marinus +6 more
TL;DR: It appeared that studies which applied a comparable design identified similar subtypes in Parkinson's disease, and the cluster profiles “old age‐at‐onset and rapid disease progression” and “young age-at‐onet and slow disease progress” emerged from the majority of studies.
Journal ArticleDOI

TL;DR: This work investigated whether ANG variants could predispose to both ALS and PD, and found a few ALS patients carrying ANG variants also showed signs of Parkinson disease.
Journal ArticleDOI
Clinical subtypes of Parkinson's disease
Stephanie M. van Rooden,Fabrice Colas,Pablo Martinez-Martin,Martine Visser,Dagmar Verbaan,Johan Marinus,Ray K. Chaudhuri,Joost N. Kok,Joost N. Kok,Jacobus J. van Hilten +9 more
TL;DR: Four similar PD subtypes were identified in two different populations and are largely characterized by differences in the severity of nondopaminergic features and motor complications and likely reflect complex interactions between disease mechanisms, treatment, aging, and gender.
