Parkinson''s disease (PD) is a progressive nervous system movement disorder. As brain neurons weaken or die, individuals may experience issues like tremors, stiffness, and impaired balance. Symptoms may worsen over time, affecting daily activities. While there is no cure, ongoing research and treatments, including medications and surgery, can significantly improve motor symptoms. PD''s main symptoms include tremors, muscle stiffness, slowed movement (bradykinesia), and postural instability, impacting balance and increasing fall risks. The progression varies among individuals, and symptoms often start on one side before affecting both. PD may lead to a distinctive walking pattern, characterized by leaning forward, quick steps (festination), and reduced arm swinging.
