Parkinson’s Disease (PD) is a progressive neurological disorder primarily affecting movement. Named after the British physician James Parkinson, who first described its symptoms in 1817, PD is characterized by a variety of motor and non-motor symptoms that can significantly impact an individual’s quality of life. Here are some of the most important aspects to understand about Parkinson’s Disease:

Symptoms: The hallmark symptoms of Parkinson’s Disease include tremors, bradykinesia (slowed movement), rigidity (stiffness in the limbs and trunk), and postural instability (difficulty with balance and coordination). These motor symptoms often start on one side of the body and eventually affect both sides as the disease progresses

Non-Motor Symptoms: Parkinson’s Disease can also present as a range of non-motor symptoms, including cognitive changes (such as difficulty with memory and executive function), mood disorders (such as depression and anxiety), sleep disturbances, constipation, loss of sense of smell, and autonomic dysfunction (such as hypotension and urinary problems).

DiagnosisThere is no specific test for Parkinson’s Disease, so diagnosis is based primarily on medical history, a physical examination, and the presence of characteristic symptoms. Neuroimaging techniques such as MRI and DaTscan may be used to help rule out other conditions that can mimic PD.
