Many dementia patients have a combination of Alzheimer's disease and vascular dementia. This is often called "mixed dementia."

Identification of Alzheimer and vascular lesion thresholds for mixed dementia
SUMMARY To explore the pathological substrates of mixed dementia, we performed a detailed analysis of lacunar and microvascular pathology in 156 autopsied, elderly individuals with various degrees
Mixed dementia -- emerging concepts and therapeutic implications
ABSTRACT Context: The prevalence of mixed dementia, defined as the coexistence of Alzheimer disease (AD) and vascular dementia (VaD), is likely to increase as the population ages. Objectives:
Rethinking the dementia diagnoses in a population-based study: what is Alzheimer's disease and what is vascular dementia?
OBJECTIVE: To explore the hypothesis that older adults often are affected by more than one disease, making the differential diagnosis between Alzheimer's disease (AD) and vascular dementia (VaD) diffi
Vascular Dementia and Alzheimer's Disease: Diagnosis and Risk Factors
Dementia is a neurological disease that is associated with aging. The incidence and prevalence of dementia is increasing as the population continues to age. The two most common forms of dementia are A
