Understanding Parkinson’s Disease: Key Facts and Symptoms

Parkinson’s disease is a long-term neurological disorder that impacts movement, caused by the gradual degeneration of nerve cells in the brain. This progressive condition primarily affects the substantia nigra, where the loss of neurons leads to decreased dopamine production — a chemical essential for controlling movement and coordination. As dopamine levels drop, individuals may experience difficulty in controlling their movements, which worsens over time.

While the exact cause and cure remain unknown, several medications can help manage symptoms. Recognizing early signs is vital for timely intervention.

This results in challenges with daily activities, including tremors, stiffness, and impaired speech. Early symptoms often include subtle tremors, reduced sense of smell, movement difficulties, speech changes, writing struggles, posture alterations, and loss of automatic movements. The progression of Parkinson’s disease varies between individuals, categorized into five stages from mild to severe, with increasing difficulties in mobility and independence. Recognizing these stages helps in planning appropriate care and management. Consult healthcare professionals if symptoms arise to ensure proper diagnosis and treatment.
