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. Relevant screening tools and a complete physical examination are essential. Making the correct diagnosis lets patients and caregivers make arrangements, have more timely access to services, improve patient quality of life, and lessen the burden on caregivers.
