[Dementia with Lewy bodies].

Area of Science:

• Neurology
• Neuroscience
• Pathology

Background:

• Dementia with Lewy bodies (DLB) is a neurodegenerative disorder.
• Histopathological hallmarks include alpha-synuclein deposition in inclusion bodies.
• Clinical diagnosis relies on cognitive deficits, fluctuations, hallucinations, REM sleep disorders, and Parkinsonism.

Purpose of the Study:

• To review the diagnostic criteria for Dementia with Lewy bodies.
• To discuss current therapeutic strategies for managing DLB symptoms.
• To highlight the limitations in evidence-based treatment approaches due to limited research.

Main Methods:

• Review of clinical diagnostic criteria for DLB, including the 2017 updates.
• Analysis of current therapeutic concepts for motor, cognitive, and behavioral symptoms.
• Assessment of the current state of research and evidence base for DLB therapies.

Main Results:

• The 2017 criteria aim to improve differentiation of DLB from other neurodegenerative diseases.
• Therapeutic strategies encompass managing motor, cognitive, and psychological/behavioral symptoms.
• A limited number of studies restrict the development of evidence-based therapy approaches for DLB.

Conclusions:

• Improved diagnostic criteria enhance the clinical identification of DLB.
• Symptomatic management is the current focus of DLB therapy.
• Further research is crucial to establish robust, evidence-based treatment guidelines for DLB.
