"Our findings represent a growing challenge for the health care system as baby boomers age and their risk of stroke and dementia increases," lead study author Dr. Gustavo Saposnik, of the University of Toronto in Canada, said in a journal news release.
"How to best manage stroke patients with pre-existing dementia is under debate and raises several diagnostic, management and ethical issues as some facilities may limit access to specialized stroke care for dementia patients unless the care is likely to improve outcomes," he noted.
"The lack of established guidelines for the management and treatment of stroke patients with dementia contributes to this uncertainty," Saposnik added.

itself or other factors such as hypertension, diabetes, atrial
fibrillation and smoking are responsible for the poorer prognosis
that stroke patients with pre-existing dementia face.
