Background: Gender differences for dementia with Lewy bodies (DLB), usually considered an intermediate disease between Alzheimer disease (AD), Parkinson disease (PD), and Parkinson disease with dementia (PDD), is controversial. The present study investigated gender differences in DLB and PDD using demographic and pharmacologic treatment strategies in a retrospective data analysis. Method: Data of confirmed cases of DLB and PDD between 2015 and 2020 were collected from the PRISMA dementia data-base registry. Data from 7594 PDD patients and 608 DLB patients were analyzed using logistic regression analysis to determine demographic and pharmacologic factors associated with DLB and PDD patients. Result: In the adjusted analysis, central acetylcholinesterase inhibitors (ChEIs) including donepezil, galantamine, rivastigmine were associated with DLB. Second generation antipsychotics (SGAs) such as risperidone (odd ratio(OR)=1.900, 95% confidence interval (CI),1.192–3.030, P = 0.007) was associated with females with DLB while aripiprazole (OR=0.195,95% CI,0.06–0.631, P<0.006), and a selective serotonin receptor inhibitor (SSRIs) including escitalopram (OR=0.651, 95% CI,0.468–0.906, P = 0.011), and demographic factors including tobacco use (OR=0.620, 95% CI,0.444–0.866, P<0.005) and increasing age (OR =1.042, 95% CI, 1.025–1.058, P<0.001), were associated with females that present with PDD. Olanzapine (OR=2.871, 95% CI, 1.902–4.334, P<0.001), escitalopram (OR=1.444, 95% CI, 1.079–1.932) and tobacco use (OR=1.424, 95%CI, 1.075–1.887, P = 0.014) were associated with males with DLB. African American males (OR= 0.249, 95% CI, 0.088–0.703, P = 0.009) with a history of ethyl alcohol (ETOH) use (OR= 0.371, 95% CI, 0.260–0.531, P<0.001) treated with aripiprazole (OR=0.581, 95%CI, (0.302–1.118), P = 0.004) were associated with PDD. Conclusion: Our findings reveal similarities and differences in demographic and pharmacologic factors associated with DLB and PDD. Investigating the effect of identified factors on DLB or PDD in future studies can help improve the care of DLB and PDD patients.
