Mixed Type

increasing evidence shows that VaD and AD often coexist in older patients and is called mixed dementia
cardiovascular disease (CVD) is the pathology and VaD is the disorder and VaD with no AD pathology is relatively uncommon as shown in the figure below

many patients have overlap of AD and significant CVD
over 60% of patients diagnosed with AD also have incomplete white matter infarction on imaging [3]
cerebral ischemia and amyolid deposits may synergize to produce AD and vascular changes in the brain [4]
a great deal of research is currently being conducted to clarify these mechanisms
