The evolving therapeutic landscape of dementia with Lewy bodies.

Dementia with Lewy bodies has a complex clinical presentation, with symptoms spanning cognitive, neuropsychiatric, motor, autonomic, and sleep domains. The disorder causes high morbidity, is associated with high caregiver burden, and can result in considerable health-care costs. Although symptomatic treatments remain scarce, emerging evidence supports a multipronged approach that integrates pharmacological and non-pharmacological interventions that target different signs and symptoms. Novel frameworks, such as the DIAMOND Lewy toolkit, provide structured management guidance. Beyond symptom control, research is at a turning point, with increasing focus on disease-modifying therapies. Ongoing clinical trials are exploring many therapeutic targets, including α-synuclein aggregation and neuroinflammation. Other potential targets in the treatment of dementia with Lewy bodies include amyloid β, given that the presence of Alzheimer's disease copathology is common in patients with this disease.
