Medication Nonadherence in Parkinson’s Disease

A number of previously fatal neurological conditions have been rendered treatable, chronic conditions by advances in research. As clinicians delivering a diagnosis such as Parkinson’s Disease (PD) to a concerned patient, we take solace in the knowledge that we have many symptomatic therapies to restore quality of life. Just as we consider the individual’s pertinent symptoms and comorbidities in selecting treatments, we must also consider the prevalence and impact of medication non-adherence. Previously referred to as medication compliance, the term “medication adherence” is preferred as it emphasizes patient autonomy and decision-making (1, 2).
