Parkinson's Disease Overview
- Parkinson's Disease, a progressive neurodegenerative disorder affecting mobility, manifests clinically through slowness, stiffness, and sometimes tremors.
- Non-motor symptoms like loss of smell, mood changes, and autonomic dysfunction can precede motor issues, with cognitive problems also prevalent.
Dopamine, Circuits, and Compensation
- Dopamine loss in Parkinson's disrupts brain circuitry, impacting automatic movements controlled by the basal ganglia.
- The brain compensates by relying on volitional movement circuits, potentially leading to cognitive saturation and increased fall risk.
Parkinson's Prevalence and Causes
- Parkinson's Disease, the second leading neurodegenerative disorder, affects 1 in 100 people over 50.
- Genetic risk factors are prominent in young-onset cases, while a mix of environmental and genetic factors influences older-onset Parkinson's.
