    Dementia with Lewy bodies (DLB) is a complex neurodegenerative disorder characterized by cognitive decline, neuropsychiatric symptoms, and parkinsonism.

  • 2

    Key genetic risk loci for DLB include APOE, GBA, and SNCA, which influence biological processes like lipid metabolism and neuroinflammation.

  • 3

    Environmental factors such as pesticides and air pollution are linked to α-synuclein aggregation and may exacerbate DLB pathology.

  • 4

    DLB exhibits clinical and biological heterogeneity, with distinct pathological trajectories and coexisting conditions like Alzheimer's disease.

  • 5

    Current understanding of DLB emphasizes the interplay between genetic predisposition and environmental factors in disease expression.
