Answer

DLB has been described in Asian, African, and European races. Data concerning the relative frequency of DLB in different races are not available. Most studies suggest that DLB is slightly more common in men than in women.

DLB is a disease of late middle age and old age. The aforementioned study in southwestern France found that the incidence of DLB increased continuously with advancing age, whereas that of Parkinson disease decreased after age 85 years. [10]
