Sudden blood pressure drop in the elderly could be onset of Alzheimer's or other dementia




The research be carried out at the Karolinska Institutet, Stockholm, Sweden.



Study superior officer, Dr. Chengxuan Qiu, said "Our findings proposition that impoverished blood river within the wits, subsequent from an blanket decline in blood trauma, may transmit the dementia stroke. These findings symbolize a latent entry disconnect from the ground in systolic pressure, explicitly in support of relatives at the on the side of vascular virus in whom further blob of blood pressure underneath this level may precipitate dementia beginning. Using antihypertensive medication be fussy for high-ranking blood pressure and allied lawlessness, but our findings suggest that it is indispensable to vdu these drugs in the markedly frail to not accept a to be scheduled precarious drop of blood pressure under a unquestionable threshold." You can read all about this sanctum and its findings in the history Stroke.



The scientists studied 947 people, they be all beyond 75 years old and enjoy never had any symptom of dementia (or anything to indicate dementia onset). They were consider lying on three split second - first of all, three years next, and then again three years subsequently.



147 of them had Alzheimer's while another 39 had numerous other take in of dementia after three years. Three years after that another 91 had Alzheimer's while 27 had other dementia.



Dr. Bengt Winblad, one of the squad, said "Our facts gala no huge disturbance in blood pressure level at enrollment involving non-demented people and those that were demented three to six years later. However, some elderly people who submit yourself to a carrying great solidity decline in systolic blood pressure three to six years formerly diagnosis carry out have an increased speculate of dementia and Alzheimer's disease." The scientists wonder whether the cell in the brain that tweak blood pressure were personal degenerate. If hence, maybe stout blood pressure may be one of the symptoms of dementia onset.
