esempi grafici opzioni binarie fluctuating blood pressureOlder people who have more-than-average fluctuating blood pressure are at a higher risk of impaired cognitive function, according to recent research.[1] Dr. Simon Mooijaart of Leiden University Medical Centre in the Netherlands, and colleagues state that elements of the vascular system may contribute to the development and progression of dementia.1 Some of these cardiovascular risks may be reversible, but some may not.1

buy tastylia Mooijaart and colleagues investigated the link between variability in blood pressure and cognitive function in 5,461 people aged 70 to 82, who resided in Ireland, Scotland, and the Netherlands.1 All of the participants were taking part in a study of the impact of statin drugs on blood vessel health, as they were all at risk of cardiovascular disease.1 Their blood pressure was measured every three months, and a mental state examination was used to test cognitive function at the beginning of the study in order to exclude those with poor cognitive function.1 Then, after a follow-up of three years, participants were tested on four areas of cognitive function: attention, processing speed, immediate memory, and delayed memory.1

Seroquel from india Researchers concluded, “Higher visit-to-visit variability in blood pressure, independent of average blood pressure and cardiovascular disease, was associated with impaired cognitive function in old age.”1

binäre optionen sitz deutschland “Our findings may suggest that decreased hippocampal volume, cerebral microbleeds, and cortical infarcts are potentially pathogenic mechanisms behind the association between variability in blood pressure and cognitive impairment,” researchers state.1
