Lowering Cholesterol, Blood Pressure May Reduce Alzheimer’s Risk

WEDNESDAY, April 13, 2011 (Health.Com) — Treating traditional stake factors in lieu of mind disease such as hypertension, high-pitched cholesterol, and diabetes may possibly besides prevent the progress of mild reminiscence and cognitive problems into full-blown Alzheimer’s disease, a just starting out study suggests.

Although dietary changes, cholesterol-lowering statins, and hypertension drugs such as beta-blockers are far from a surefire way to prevent Alzheimer’s, these and other treatments with the aim of promote healthy blood vessels may possibly be a applied way in lieu of family to reduce their stake, the researchers say.

The study, which was conducted in tableware and in print in the journal Neurology, “highlights the significance of midlife vascular stake factors in lieu of Alzheimer’s disease, which, unlike age and genetics, can be modified,” says Whitney Wharton, PhD, a inquiries scientist by the University of Wisconsin’s Alzheimer’s Institute, in Madison, who was not involved in the inquiries.

Researchers by Daping Hospital, in Chongqing, followed 638 men and women on top of the age of 55 in lieu of five years. All the study participants had problems with reminiscence and mental function with the aim of were noticeable but not rigorous adequate to interfere with their day after day functioning. This condition, proven as mild cognitive impairment, progresses to Alzheimer’s in roughly 10% to 15% of bags both time, according to the study.

Forty-five percent of the participants went on to develop serious dementia uniform with Alzheimer’s disease. Those who had high-pitched cholesterol, hypertension, diabetes, or an extra heart-related stake reason were twice as likely to progress to Alzheimer’s compared to family with rebuff stake factors.

Treatment substantially cut-rate the stake, however. Compared to folks receiving rebuff care, the participants who took medication or other steps to expand their mind healthiness were 39% a smaller amount likely to convert to Alzheimer’s. Those receiving care in lieu of specifically various of their stake factors were 26% a smaller amount likely to develop the disease.

Researchers state long been aware of an clear link linking blood-vessel healthiness and Alzheimer’s, but this study is “the originator lone with the aim of shows with the aim of treating mild cognitive impairment can state results,” says Anton Porsteinsson, MD, director of the Memory Disorders Clinic by the University of Rochester School of Medicine, in New York.

It’s not earn why treating heart-related stake factors might drop the stake of Alzheimer’s, but high-pitched blood pressure and high-pitched cholesterol may possibly affect the accumulation of the protein plaques in the brain with the aim of are a guarantee of the disease, the authors say.

Though the results are promising, the study can’t show with the aim of care completely lowers Alzheimer’s stake. Randomized controlled trials, which are considered the gold standard in lieu of therapeutic inquiries, will be desired to confirm the findings. The study will besides need to be replicated in other countries.

Ian Murray, PhD, an assistant professor of neuroscience and experimental therapeutics by the Texas A&M Health Science Center College of Medicine, in College Station, says with the aim of the results would likely be the same in a non-Chinese population.

The study findings “are more than applicable,” he says, “as the Western population tends to state a superior incidence of metabolic disease such as stoutness and high-pitched cholesterol.”
