Pooling data from three separate cohorts, researchers studied 147 subjects with DLB, 236 subjects with Alzheimer’s disease and 294 healthy controls to identify risk factors for DLB. Subjects

were studied to see if 19 different risk factors that were associated with AD and PD were also risk factors for DLB. The study revealed the risk factor profile of DLB appears to combine

aspects of both AD and PD. A history of depression or anxiety, a family history of PD, history of stroke, and the APOE genetic variant were associated with a greater risk for DLB.
