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.
Parkinsonism is a clinical syndrome characterized by tremor, bradykinesia (slowed movements), rigidity, and postural instability. [1] [2] Both hypokinetic (bradykinesia and akinesia) as well as hyperkinetic (cogwheel rigidity and tremors at rest) features are displayed by Parkinsonism. [3]
The second major proposed mechanism for neuronal death in Parkinson's disease, autophagy, is a mechanism by which inner components of the cell are broken down and recycled for use. [2] [6] Autophagy has been shown to play a role in brain health, helping to regulate cellular function. Disruption of the autophagy mechanism can lead to several ...
Parkinson's (disambiguation) Parkinson's disease, degenerative disorder of the central nervous system; Parkinsonism, also known as Parkinson's syndrome, atypical Parkinson's, or secondary Parkinson's; Parkinson's Law, the adage "Work expands so as to fill the time available for its completion."
Parkinson-plus syndromes are usually more rapidly progressive and less likely to respond to antiparkinsonian medication than PD. [10] [11] However, the additional features of the diseases may respond to medications not used in PD. [citation needed] Current therapy for Parkinson-plus syndromes is centered around a multidisciplinary treatment of ...
As for autopsies, the work of the neuropathologist is to make post-mortem diagnosis of diseases such as dementia, Parkinson's disease and other conditions that affect the central nervous system. Tissue samples are researched within the lab for diagnosis, and in forensic investigations to clarify the cause of death.
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 2012 study suggests that players in the National Football League are three times more likely to die from neurodegenerative diseases, including Alzheimer's and Parkinson's diseases, than the general US population. [43] A 2018 study found 56% increase in risk of Parkinson's disease among US military veterans suffered traumatic brain injury. [42]
