Parkinson’s Disease: A Comprehensive Academic Resource
An evidence-based, rigorously cited guide to understanding Parkinson’s disease — from molecular genetics to emerging therapies. Designed for patients, caregivers, students, and healthcare professionals.
Understanding the Second Most Common Neurodegenerative Disease
Parkinson’s disease (PD) is a progressive neurodegenerative disorder that affects over 8.5 million people worldwide, making it the fastest-growing neurological condition in the world (World Health Organization, 2023; Dorsey et al., Journal of Parkinson’s Disease, 2018). The disease is characterized by the loss of dopamine-producing neurons in the substantia nigra pars compacta, leading to a complex constellation of motor and non-motor symptoms that profoundly impact quality of life.
This resource synthesizes findings from the world’s most authoritative sources — including the National Institutes of Health (NIH/NINDS), the Movement Disorder Society (MDS), the Parkinson’s Foundation, the Michael J. Fox Foundation, Mayo Clinic, Johns Hopkins Medicine, Cleveland Clinic, the World Health Organization, and leading peer-reviewed journals — to provide a comprehensive, academically rigorous overview of every facet of the disease.
