Abstract
AbstractINTRODUCTIONThe prevalence of cerebral smallvessel disease (SVD) and vascular dementia according to workplace or domestic exposure to hazardous substances is unclear.METHODSWe included studies assessing occupational and domestic hazards/at‐risk occupations and SVD features. We pooled prevalence estimates using random‐effects models where possible, or presented a narrative synthesis.RESULTSWe included 85 studies (n = 47,743, mean age = 44·5 years). 52/85 reported poolable estimates. SVD prevalence in populations exposed to carbon monoxide was 81%(95% CI = 60‐93%; n = 1373; results unchanged in meta‐regression), carbon disulfide73% (95% CI = 54‐87%; n = 131), 1,2‐dichloroethane 88% (95% CI = 4‐100%, n = 40), toluene 82% (95% CI = 3‐100%, n = 64), high altitude 49% (95% CI = 38‐60%; n = 164),and diving 24% (95% CI = 5‐67%, n = 172). We narratively reviewed vascular dementia studies and contact sport, lead, military, pesticide, and solvent exposures as estimates were too few/varied to pool.DISCUSSIONSVD and vascular dementia may be associated with occupational/domestic exposure to hazardous substances.
