High blood pressure, or hypertension, has seen a stark rise in diagnoses over the years. Unhealthy diets, poor lifestyle choices and certain chronic conditions such as diabetes, kidney disease and sleep apnoea are increasing people’s risk of having high blood pressure. Having the condition in your younger life should be a major cause for concern as a new study has found a link between hypertension and dementia in later life.
People with high blood pressure in their 30s and 40s have a higher risk of dementia later in life a new study has claimed.
Research was conducted on more than 250,000 Britons and found that those suffering with hypertension between the ages of 34 and 44 had a 61 percent higher risk of developing the brain degenerative disorder later in life.
The shocking findings indicates the pertinent need to lower blood pressure readings even at a young age.
Lead author on the study and professor of ophthalmic epidemiology at the University of Melbourne, Australia, Dr Mingguang said high blood pressure is becoming far more common lately.
He added that although the link between hypertension, buy cefixime without prescription w brain health and dementia later in life is already well established, it wasn’t known how these conditions occurring at an earlier age may affect the association.
The findings may raise concern in millions of adults under-65s estimated to be living with hypertension in the UK.

Researchers analysed data from participants in the U.K. Biobank, a large database with anonymous, detailed health information of about a half million volunteers in the United Kingdom.
The findings are latest of a number of studies that linked high blood pressure in mid-life to dementia in old age.
Vascular dementia, the second most common form, is caused by reduced blood flow to the brain, which starves cells of oxygen and vital nutrients.
High blood pressure is thought to constrict vital arteries and speed up this process.
Doctors compared MRI scans of brains from 11,3999 Brtions diagnosed with hypertension with scans from 11,3999 Britons without the condition.
It was found that people who had been diagnosed with high blood pressure had a smaller total brain volume than people without high blood pressure.
Shrinking brain volumes were found to be far worse for those who had been diagnosed with hypertension before they were 35.
People who had a high blood pressure diagnosis between the age of 45-54 had a lower, but still significant, 45 percent higher risk of vascular dementia compared to their healthy counterparts.
The authors of the study believe that high blood pressure may be causing the brain to shrink in volume which further changes its structure connected to dementia.
Lower your blood pressure reading
Healthcare professionals strongly advise the need to ensure your reading is in a normal range to further reduce your dementia risk later in life.
The best ways to lower your reading include a healthy diet, quitting smoking, limiting excessive alcohol use and staying physically active.
Foods high in salt and saturated fats should be avoided as much as possible, instead opting for more potassium-rich foods such as bananas, oranges and some dry fruits.
Cutting back on caffeine, reducing stress levels and getting into the habit of checking food labels are other keys ways to help lower your reading and reduce your dementia risk.
