Ans :B-Parkinson’s Disease
- The loss of the dopamine neurons in the midbrain of the human brain is the main feature of Parkinson’s disease.
- Approximately 50%-60% of the dopamine neurons are damaged, when a person is detected with Parkinson’s disease.
- These dopamine neurons, present in the substantia nigra of the midbrain, releases a neurotransmitter known as dopamine which is circulated into different areas of the brain.
- The loss of dopamine-containing neurons in the midbrain affects different parts of the nigral complex up to various levels. This loss increases with disease progression.
- Motor Symptoms of parkinson’s Disease include:Bradykinesia,Rigidity,Tremor, Postural instability
