Coexisting Dementia Rising Among Stroke Patients

J Stroke Cerebrovasc Dis; ePub 2018 Mar 14; Sherzai, et al

Rates of coexisting dementia among patients hospitalized for stroke in the US have risen over the last decade, according to a recent study. Prevalence of dementia among these patients varies by gender and race-ethnicity. Patient admission data between 1999 and 2012 were sourced from the National Inpatient Sample. Admission records were included in the retrospective analysis if patients were diagnosed with ischemic or hemorrhagic stroke during admission. Predictors of dementia subtype were analyzed using unadjusted and adjusted multinomial logistic regression. Researchers found:

  • Of 1,170,051 patients hospitalized for stroke between 1999 and 2012, 66,703 (5.7%) had a coexisting diagnosis of dementia.
  • Female gender was associated with increased odds of Alzheimer dementia (AD) but decreased odds of both vascular dementia (VaD) and non-Alzheimer-nonvascular dementia.
  • Relative to whites, African-Americans had higher odds of AD and VaD.
  • Similarly, Hispanics had increased odds of AD.
