Parkinson's disease (PD), or simply Parkinson's, is a neurodegenerative disease primarily of the central nervous system, affecting both motor and non-motor systems. Symptoms typically develop gradually, with non-motor issues becoming more prevalent as the disease progresses.
There are three main types of synucleinopathy: Parkinson's disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA). [1] Other rare disorders, such as various neuroaxonal dystrophies, also have α-synuclein pathologies. [ 2 ]
Parkinsonism is a clinical syndrome characterized by the four motor symptoms found in Parkinson's disease: tremor, bradykinesia (slowed movements), rigidity, and postural instability. [ 1 ] [ 2 ] Parkinsonism gait problems can lead to falls and serious physical injuries.
Parkinson's Disease causes constipation and gastric dysmotility that is severe enough to endanger comfort and even health. [26] A factor in this is the appearance of Lewy bodies and Lewy neurites even before these affect the functioning of the substantia nigra in the neurons in the enteric nervous system that control gut functions.
Parkinson's disease (PD), the second most common neurodegenerative disease after Alzheimer's disease, affects 1% of people over 60 years of age. [1] [2] [3] In the past three decades, the number of PD cases has doubled globally from 2.5 million in 1990 to 6.1 million in 2016. [4] [5] As of 2022, there are ~10 million PD cases globally. [6]
A higher-than-expected prevalence of gene mutations in Parkinson’s disease patients suggests genetic testing should be offered to them more broadly, researchers said on Monday in the medical ...
Frontotemporal dementia and parkinsonism linked to chromosome 17 (FTDP-17) is an autosomal dominant neurodegenerative tauopathy and Parkinson plus syndrome. [3] FTDP-17 is caused by mutations in the MAPT (microtubule associated protein tau) gene located on the q arm of chromosome 17, and has three cardinal features: behavioral and personality changes, cognitive impairment, and motor symptoms.
On Thursday, the FDA approved AbbVie Inc’s (NYSE:ABBV) Vyalev (foscarbidopa and foslevodopa) as the first and only subcutaneous 24-hour infusion of levodopa-based therapy for motor fluctuations ...
