Accounting for up to 20 percent of all forms of dementia, Lewy Body Dementia affects approximately 1.4 million Americans. Lewy Body Dementia (LBD) is the second most common cause of progressive dementia behind Alzheimer's disease. LBD is also the most misdiagnosed form of dementia because symptoms are closely related to Parkinson's disease and dementia with Lewy Body (referred to as DLB).
