Parkinson’s disease, also known as “tremor paralysis,” is characterized by slow movements, tremors in the arms, legs, or other parts of the body, and a loss of flexibility and stiffness. The disease was first described systematically by the British physician Jaime Parkinson. At that time, it was not known what type of disease the disease should be classified as, and the disease was called “tremor palsy”. To date, the cause of Parkinson’s disease remains unclear. Current research favors a combination of age-related aging, genetic susceptibility, and exposure to environmental toxins. Ageing: Parkinson’s patients are mainly seen in middle-aged and older adults over the age of 50, and show a trend toward higher incidence with age. Environmental factors: Epidemiological findings have revealed regional differences in the prevalence of Parkinson’s disease, so it is suspected that there may be toxic substances in the environment that damage the brain’s dopamine neurons. Familial heritability: Medical practitioners have found over time that Parkinson’s disease seems to have a tendency to cluster in families, and families with familial onset of Parkinson’s disease have relatives with a somewhat higher incidence than the normal population. Genetic susceptibility: Although Parkinson’s disease is associated with aging and environmental toxins, not all older adults or people exposed to the same environment develop Parkinson’s disease. Although there is also a family clustering of patients with Parkinson’s disease, most patients are sporadic, and to date, no clear causative gene has been found in disseminated Parkinson’s disease patients.
