Apathy is independent from depression and dementia in Parkinson's disease
TORONTO - A study investigating the correlation between apathy, depression and dementia in Parkinson's disease was presented today at The Movement Disorder Society's 15th International Congress of Parkinson's Disease and Movement Disorders.
The study, led by Gabriel Robert, MD, of Rennes, France, reveals that apathy, a core characteristic of Parkinson's disease, is not related to depression and dementia in PD, and is also unrelated to motor aspects of the disease.
Forty-five non depressed and non demented PD patients were assessed using the Apathy Evaluation Scale (AES). Results showed the AES score was not correlated to motor scores or levodopa treatment. Imaging data were also analyzed with the Statistical Parametric Mapping 2.
Daniel Weintraub, MD, of the University of Pennsylvania, supports these findings by stating, "This research is significant for a few reasons. First, it further documents that abnormalities in prefrontal cortex, in this case metabolic derangements, may underlie the development of apathy in patients with Parkinson's disease. The PET imaging results from this study nicely complement the findings of studies of apathy in PD patients that have used structural imaging and neuropsychological testing. In addition, the exclusion of depressed patients in this study population is additional evidence that although apathy and depression in PD overlap to some extent, they are also distinct disorders."
