Memory problems in middle age appear due to high blood pressure


memoryAccording to research of the American Academy of Neurology high blood pressure can cause the memory problems in people over 45.
Nearly 20,000 people age 45 and older were involved in the study. A total of 1,505 of the participants, or 7.6 percent, had cognitive problems, and 9,844, or 49.6 percent, were taking medication for high blood pressure.
High blood pressure is defined as a reading higher than 140/90 or taking medication for high blood pressure.
While studying, it was discovered, that people with high diastolic blood pressure were more likely to have cognitive impairment, or problems with their memory and thinking skills, than those people who has normal diastolic readings.
Research has shown that high diastolic blood pressure leads to weakening of small arteries in the brain, which can result in the development of small areas of brain damage.
The results were valid after adjusting for other factors that could affect cognitive abilities, such as age, smoking status, exercise level, education, diabetes or high cholesterol.
Its possible that by preventing or treating high blood pressure, you could potentially prevent cognitive impairment, which can be a precursor to dementia.
