Lewy body dementia, an umbrella term for both Parkinson’s disease dementia and dementia with Lewy bodies

lewy body dementiaLew body dementia (LBD) is an umbrella term referring to both Parkinson’s disease dementia and dementia with Lewy bodies. In dementia with Lewy bodies, cognitive symptoms interfering with daily living present themselves before or within one year of Parkinson’s-like movement problems. In Parkinson’s disease dementia, cognitive symptoms usually don’t appear until after a year of the onset of movement problems.

Researcher Howard I. Hurtig explained, “An early and accurate diagnosis may be lifesaving. The avoidance of medications that can worsen the symptoms of LBD cannot be overemphasized. Every patient with LBD and their caregiver(s) should memorize the list of acceptable and forbidden drugs.”

Lewy body dementia is characterized by an abnormal buildup of Lewy bodies in areas of the brain responsible for memory, behavior, movement, and personality. Parkinson’s disease symptoms primarily affect mobility and motor abilities. Diagnosis can be difficult because more than one cognitive disorder can be causing changes in the brain. For proper diagnosis and differentiation between dementia and Parkinson’s disease, it’s best to consult with a neurologist or geriatric physician.
