Middle aged women with high blood pressure have a higher risk of dementia

According to a recent article in the journal Neurology, for women in their 40s or so, people with high blood pressure tend to be more likely to develop dementia in the future   "We've known for a long time that high blood pressure symptoms in middle age are a known risk factor for dementia, but this study can help us better understand when high blood pressure affects the onset of dementia and the extent to which different gender groups are affected," said Dr Rachel a Whitmer, author of the paper   The study included 7238 volunteers who collected blood pressure information at an average age of 33 and 44 Among them, 22% of the volunteers had symptoms of hypertension when they were about 30 years old (31% for men and 14% for women) The overall proportion of hypertension had no change when they were about 40 years old, but the proportion of men decreased to 25% and that of women increased to 18%   The researchers then tested the health of the remaining 5646 volunteers in 1996 and recorded their dementia for up to 15 years In fact, 532 people were diagnosed with dementia during this period   Further analysis showed that there was no significant correlation between early hypertension (about 30 years old) and dementia in old age, but the effect of hypertension on dementia in middle age was 65% After correcting the interference of other possible risk factors, the author found that the correlation still holds   Therefore, for middle-aged women with high blood pressure, timely diagnosis and prevention of dementia seems to be very necessary.
