Dementia with Lewy bodies (DLB) is a common neurodegenerative condition. DLB is the second most common cause of neurodegenerative dementia after Alzheimer’s disease. DLB patients present with a wide range of cognitive impairment, neuropsychiatric symptoms, sleep behavior disorder, motor and autonomic dysfunction. The clinical presentations vary between patients and can change over time within an individual. DLB is characterized by the accumulation of aggregated alpha-synuclein protein in Lewy bodies and Lewy neurites, similar to Parkinson’s disease. The result of treatments is promising in one symptom but worsen another, which makes disease management difficult. There are currently no US FDA-approved medications specifically for the treatment of DLB, though many of them that are approved for Alzheimer’s disease are widely used in the treatment of DLB with varying degrees of success. This article presents the basic concepts, symptoms, pathology and pathogenesis and the latest updated new criteria information of DLB based on current understanding to help teams of physicians and caregivers inform those in need about the disease and provide adequate support for DLB patients
