[Health Channel/Comprehensive Report]In addition to causing cardiovascular disease, heart health also makes the brain age faster! according to”Science Daily“(Science Daily) reported that the University College London study found that people with poor cardiovascular health at the age of 36 have a higher brain age in later life, and men’s brains also decline faster than women. Research published inLancet Longevity》。
The researchers looked at the subjects’ brains through MRIs, where machine learning had been established, and because the subjects were a long-term survey of people born in the UK in 1946, the researchers were able to correlate their brain age with the age of their brains over the course of their lives. They compared various factors and found that when their average chronological age was 70.7 years, the average predicted brain age of women was 65.2 years, while the average predicted brain age of men was 70.2 years.

People aged 36 and 69 with poor cardiovascular health had poorer brain health, as did people whose MRI showed increased cerebrovascular disease, which is related to blood flow and blood vessels in the brain, the researchers said. This is in line with previous findings from previous research that found that people with high blood pressure at age 36 had poorer brain health later in life.
Looking back at the experiences of this group of subjects, the researchers noted that the findings could explain one-third of the variability in brain age, and also found that early brain aging was not associated with childhood cognitive function, education, or socioeconomic status. In addition, higher concentrations of neurofilament light protein (NfL) were found in the blood of people with older brain ages, which are thought to be produced by damaged nerve cells, and have increased More and more studies point to the link between NfL and neurodegeneration.
Lead author Jonathan Schott, a professor at the Centre for Dementia Research at UCL, said that even if the actual age is similar, the age of the brain calculated by the machine is different, which will be the future of the face of cognitive decline. , an important predictor of other brain-related degenerative diseases.
