Exploring Parkinson’s disease: A question and answer-based approach

Parkinson’s disease (PD) is the second most common neurodegenerative disorder after Alzheimer’s disease, affecting 1%–2% people over the age of 65 years and up to 4% population over 85 years of age. Herein, we present four separate case-based scenarios commonly encountered in the neurology practice and provide the current evidence-based answers to commonly asked questions by patients, caregivers, and primary care physicians regarding the diagnosis and management of patients with PD, separating issues pertaining to early- versus late-onset PD, and management throughout various stages of disease. The discussion points within each case may apply across all cases.
