Common risk factors for Alzheimer’s disease and Vascular dementia
According to the recent epidemiological reports, there are common risk factors in Alzheimer’s disease (AD) and vascular
dementia (VaD). They can be classified into 4 major categories: demographic, genetic, vascular and comorbidity risk factors.
The demographic risk factor includes gender, aging, past history of severe head injury, educational carrier and occupational
attainment. Male gender is a risk for VaD and stroke, whereas female gender is known as a risk factor for AD. ApoE ε4 is known
to be a possible common genetic factor for both AD and cerebrovascular disease including VaD. Obesity in midlife, lack of
physical activity, cigarette smoking, and excessive alcohol intake are also regarded as risk for dementia in late life. The vascular
risk factors encompass hypertension in midlife, diabetes mellitus, dyslipidemia, congestive heart failure, myocardial infarction,
atrial fibrillation, and chronic kidney disease. It is suggested that effective management of these vascular risk factors in midlife
prevents dementia and cognitive decline in late life. Placebo-controlled randomized clinical trials of antihypertensive drugs
demonstrated that intensive antihypertensive therapy reduced the risk of VaD as well as AD in late life. Low cardiac output
due to hypotension and/or congestive heart failure has been regarded as a risk factor for cognitive impairment and dementia
especially in elderly patients whose autoregulation of cerebral blood flow is impaired. Although further research is needed,
those evidences may support a rationale for the efficacious management of vascular risk factors in the prevention of VaD as
well as AD.
