Solution:

• Parkinson’s disease affects the nervous system. It is a progressive neurodegenerative disorder that affects the central nervous system, specifically the basal ganglia. The basal ganglia are a group of structures in the brain that are responsible for controlling movement, coordination, and balance.
• Parkinson’s disease is caused by the death of dopamine-producing neurons in the basal ganglia. Dopamine is a neurotransmitter that is essential for normal movement. When dopamine levels are low, it leads to the symptoms of Parkinson’s disease, such as tremors, stiffness, slowness of movement, and difficulty with balance.
• There is no cure for Parkinson’s disease, but there are treatments that can help to manage the symptoms and improve quality of life. These treatments include medications, surgery, and physical therapy.
