Dementia with Lewy bodies: Primary care PAs can make this difficult diagnosis.

Lewy body dementia is an umbrella term for dementia with Lewy bodies (DLB) and Parkinson disease dementia. These progressive, degenerative brain disorders link dementia with psychosis and parkinsonism and are difficult to diagnose. The diagnosis of DLB is challenging, especially in its early phase, because the presentation is variable.
