Dr. Gustavo C. Roman, director of the Nantz National Alzheimer Center at the Methodist Neurological Institute in Houston, summed up decades of dementia-related research in a review paper in Alzheimer's Disease and Associated Disorders. Roman said although more definitive research is needed, focusing on the following risk factors can go a long way to helping reduce the risk of vascular dementia and mixed dementia (the combination of vascular dementia and Alzheimer's disease). By 2050, 11 to 16 million Americans will suffer some form of dementia.

Hypertension: Controlling blood pressure reduces the risk of stroke and heart disease. Studies are also beginning to show that hypertension increases the likelihood that people with mild cognitive impairment will eventually have dementia later in life.

Hyperlipidemia: Epidemiological studies show that in addition to cardiovascular disease, high blood pressure and diabetes, high blood cholesterol is an important risk factor for dementia, including Alzheimer's.

Smoking: Not only is smoking associated with increased risk of lung cancer, cardiovascular disease and emphysema, but it also adversely affects blood flow to the brain which can lead to cognitive decline and dementia.

Diabetes: Studies have already linked the obesity epidemic to increased risk of high blood pressure, metabolic syndrome, cardiovascular disease, stroke, renal failure, peripheral vascular disease, obstructive sleep apnea, and type 2 diabetes mellitus. In fact, people with this form of insulin resistant diabetes are two-to-three times more likely to face an Alzheimer's diagnosis, in part because of vascular complications.

Diet and Exercise: An overall healthy lifestyle decreases risk of dementia as people age, particularly vascular dementia. Here, the focusis on a low body mass index (25 or lower), healthy diet (based on dairy, meat, fish, fruits, vegetables, cereals, low alcohol, and the ratio of monounsaturated to saturated fat), and aerobic exercise.

Hyperhomocysteinemia: Homocysteine is an amino acid in the blood, and high blood levels are linked to an increased risk of developing Alzheimer disease. People who already exhibit signs of dementia and test positive for high levels of homocysteine are more likely to respond well to large doses of B vitamins. Research has proven that taking large doses of B-complex vitamins can reduce the rate of brain shrinkage by half in elderly people with memory problems and slow the progression of dementia.
