Overview

Parkinson’s Disease is a progressive neurological disorder affecting movement. It occurs due to degeneration of dopamine-producing neurons in the brain. Dopamine is essential for smooth and coordinated movement. The condition develops gradually. Tremors are often the first noticeable symptom. It may also cause stiffness and slowed movement. Parkinson’s can affect balance and coordination. Symptoms vary among individuals. The disease progression differs from person to person. Long-term neurological care is necessary.

Dopamine-producing cells in the substantia nigra region of the brain gradually deteriorate. Reduced dopamine disrupts motor control. This results in tremors, muscle rigidity, and slowed movements. As neuron loss continues, symptoms worsen over time.

Diagnosis

Diagnosis is based on clinical neurological evaluation. There is no single definitive laboratory test. Doctors assess motor symptoms and progression pattern. Imaging may be used to rule out other conditions.
