New research suggests that high blood pressure may affect older people's cognitive abilities, thus suggesting that stressful situations could impair their ability to think clearly.
New research suggests that high blood pressure may affect older people's cognitive abilities, thus suggesting that stressful situations could impair their ability to think clearly.
Researchers at North Carolina State University studied 36 men and women aged 60 to 87, twice a day for 60 days. After having their blood pressure taken participants were asked to complete a number of cognitive function tests. Results showed that the performance of participants whose average systolic blood pressure was 130 or higher dropped significantly when their blood pressure spiked. However the same deterioration of cognitive functioning was not seen in participants whose average systolic blood pressure was low or normal.
Study co-author Dr Jason Allaire said that the results revealed a link between blood pressure spikes in seniors with high blood pressure and a decrease in their inductive reasoning. "Inductive reasoning is important because it is essentially the ability to work flexibly with unfamiliar information and find solutions," said Allaire in a news release.
