The High Cost of Alzheimer’s Disease Misdiagnosis

A new study of Medicare beneficiaries shows that patients with vascular dementia and Parkinson’s disease who are first misdiagnosed as having Alzheimer’s disease (AD) generate substantial excess costs until they are finally accurately diagnosed.

The finding suggests a potential benefit of more accurate diagnosis of Alzheimer’s so that it can be ruled out sooner, said lead author Noam Kirson, PhD, manager at Analysis Group, an economic, financial, and strategy consultancy in Boston.

“We see that a considerable share of these Medicare beneficiaries with Parkinson’s disease and vascular dementia have a history of misdiagnosis of Alzheimer’s disease, and we also see that those who were misdiagnosed with Alzheimer’s disease incur significantly higher medical costs up to and including the period of their correct diagnosis,” Dr. Kirson concluded.
