@pangash: Parkinson's disease is a progressive brain disorder that affects movement and coordination. It happens when nerve cells in a part of the brain called the substantia nigra become damaged or die. These cells normally produce dopamine, a chemical that helps control smooth and balanced muscle movement. As dopamine levels drop, a person may develop symptoms such as: • Tremors or shaking, especially in the hands • Stiff or rigid muscles • Slowness of movement (bradykinesia) • Balance and coordination problems Parkinson's usually affects older adults and worsens over time. The exact cause is unknown, but both genetic and environmental factors may play a role. There is no cure, but medication and therapy can help manage symptoms. #healthy #healthylifestyle #parkinson
