Differentiating Alzheimer Disease, Lewy Body, and Parkinson Dementia Using DSM-5

Dementia is a growing problem with global, social, and financial repercussions. Early screening, diagnosis, education, planning, and treatment of dementia in primary care may reduce this burden. Presently, dementia is often diagnosed relatively late in the disease process, resulting in greater financial and caregiver burden. Primary care providers are often most likely to encounter patients with cognitive impairment early. The new guidelines outlined in the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition are presented to promote annual screening and early diagnosis of mild cognitive deficits by primary care providers.
