Early Recognition and Diagnosis in Parkinson's Disease

Parkinson's disease (PD) is the second most common neurodegenerative condition, with over a million people in the United States affected and 50,000-60,000 new cases diagnosed each year. The cause is unknown and there is currently no cure. It is not uncommon to mistake parkinsonian signs, such as tremor, bradykinesia, rigidity, and postural instability, as symptoms of PD, especially early in the disease course. A patient with PD may receive several different diagnoses from multiple physicians before being given the correct diagnosis. Early diagnosis of PD is especially important, as it is estimated that approximately 60-80% of dopamine neurons are lost by the time the initial motor symptoms are recognized. An advanced assessment of symptoms and an accurate diagnosis could potentially lead to earlier pharmacologic treatment or non-pharmacologic intervention, which may improve functioning and quality of life.

This volume offers a concise, focused resource on the diagnosis of Parkinson's disease by identifying and focusing on the disease's early symptoms. Written in an accessible and clear format, Early Recognition of Parkinson's Disease is part of the Oxford American Pocket Notes series, which utilizes tables, figures, bullet points, and charts for quick and easy point-of-care reference for the primary care practitioner.
