Alzheimer's Disease Is Associated With A High Blood Pressure

Alzheimer's Disease Is Associated With A High Blood Pressure.
People affliction from cardiovascular virus who have lower-than-normal blood pressure may face a higher jeopardize of brain atrophy - the death of brain cells or connections between brain cells, Dutch researchers circulate June 2013. Such brain atrophy can lead to Alzheimer's sickness or dementia in these patients ejeculation no sperm. In contrast, similar patients with high blood pressure can wearisome brain atrophy by lowering their blood pressure, the researchers added.

Blood pressure is measured using two readings. The excellent number, called systolic pressure, gauges the pressure of blood compelling through arteries. The bottom number, called diastolic pressure, measures the pressure in the arteries between heartbeats pregnancy. Normal blood on for adults is less than 120/80, according to the US National Heart, Lung, and Blood Institute.

For the study, 70 to 90 was considered typical diastolic blood pressure, while under 70 was considered low. "Our matter might suggest that patients with cardiovascular disease represent a subgroup within the public population in whom low diastolic blood pressure might be harmful," said researcher Dr Majon Muller, an epidemiologist and geriatrician at VU University Medical Center in Amsterdam.

On the other hand, lowering blood influence in kinsmen with high blood pressure might slow brain atrophy. "Our findings could insinuate that blood pressure lowering is beneficial in patients with higher blood urging levels, but one should be cautious with further blood pressure lowering in patients who already have low diastolic blood pressure".

The detonation was published in the June 10 online edition of JAMA Neurology. A US champion noted the complex effects of blood pressure levels on the brain. "High blood constrain has been shown to increase the risk of vascular brain lesions and brain atrophy. Trials of blood twist lowering in patients with hypertension have shown reduced risk of brain lesions," said Dr Gregg Fonarow, a professor of cardiology at the University of California, Los Angeles, and a spokesman for the American Heart Association.

However, in patients with hypertension, the relation between the levels of systolic and diastolic blood prevail upon and genius atrophy has been less clear. This new study suggests that low diastolic blood intimidation levels were associated with brain atrophy regardless of blood pressure levels after patients developed dementia. "These findings suggest that while healing and control of high blood compel is very important for brain and cardiovascular health, caution is needed in patients who have low diastolic blood apply pressure levels".

To see what changes blood pressure would make in the progression of brain atrophy, Muller's organization studied 663 patients who suffered from heart disease, cardiovascular disease, irrelevant artery disease or abdominal aortic aneurysm. The average age of participants was 57 and most were men. People whose diastolic blood constraint was below 70 had more brain atrophy over time, the lucubrate found.

For people with higher-than-normal blood pressure, brain atrophy decreased when their blood weight did. When blood pressure rose, however, atrophy increased. Another expert, Dr Sam Gandy, accessory director of the Mount Sinai Alzheimer's Disease Research Center in New York City, said that the judgement "is an important cautionary tale".

This implies that one must change the approach to the individual patient. Correction of hypertension is helpful, but reducing blood coercion in patients with normal blood pressure is risky and complicated" web camera online. Although the mull over found an association between low diastolic blood pressure and the risk of developing brain atrophy for race with artery disease, it did not establish a cause-and-effect relationship.
