“Pseudo-syndromes” associated with Parkinson disease, dementia, apathy, anxiety, and depression

Abstract

Purpose of reviewPhysicians treating patients with Parkinson disease must evaluate not only motor symptoms but also acquire expertise in assessing the complex behavioral features that often accompany the disease, such as dementia, apathy, anxiety, and depression.Recent findingsThere is a risk of diagnostic confusion and error because many of the behavioral and motor symptoms accentuate, overlap, or mimic each other.SummaryAwareness of potential diagnostic pitfalls and “pseudo-syndromes” should lead to more accurate clinical assessment and better care for our patients.
