A medical study at Oxford University published by the European Heart Journal has found that high blood pressure could also be linked to an increased risk of dementia increased by 45 per cent.
It may be caused by an increased chance of mini-strokes, or damage to the white matter in the brain, the researchers revealed. This is a treath for people aged 50 who have high blood pressure. Ideal blood pressure is considered to be between 90/60mmHg and 120/80mmHg, according to the study. The study constated the risk of dementia was present in participants who didn’t have other heart or blood vessel-related health issues. Participants were aged between 35 and 55 in 1985 and had their blood pressure measured throughout their life in 1985, 1991, 1997 and 2003.
Researchers discovered 385 of the 8,639 people analysed had developed dementia by 2017. People with a blood pressure of more than 130mmHg at the age of 50 had a 45 per cent greater risk of developing dementia. “Our analysis suggests that the importance of mid-life hypertension on brain health is due to the duration of exposure. So we see an increased risk for people with raised blood pressure at age 50, but not 60 or 70, because those with hypertension at age 50 are likely to be ‘exposed’ to this risk for longer,” lead researcher Professor Archana Singh-Manoux said. Extremely high blood pressure symptoms include finding blood in your urine, vision problems and having a pounding in chest.
