34, 60, 78, Our body is aging in 3 steps – this helps to detect diseases early

We are all aging. Gradually and every day – or is it? Researchers at the University of Stanford make this assumption now in question, and posit instead three points in time when the body changes really. The could improve the diagnosis of Alzheimer’s disease.

Aging runs slowly, so at least doctors thought yet. But a new Stanford University study suggests that this acceptance of the aging process, the leaves behind steadily at the same pace in traces in brain, skin, heart and organism, true.

Rather, there seems to be three age levels for the biological age of a far-reaching, and correspondingly large changes in the body mean: 34, 60 and 78 years. Since then, the number of proteins change in our blood plasma significantly, the scientists explain to Benoit Lehallier in your in the journal “Nature Medicine” published work. They had analyzed the blood plasma of 4263 people between the ages of 18 and 95 years.

Researchers speak of three “waves of aging”

“We were able to determine the subjects over time, wave-shaped changes in certain proteins,” explain the researchers. “This culminated in three waves of aging.”

In Particular, the scientists had examined about 3000 different in the blood contained protein species. Their share remained over the decades largely constant. Large fluctuations were the doctors but around the 34., 60. and the 78. The age of fixed. These changes at the Protein-level researchers with significant changes in the body, generally in connection.

Like blood and old contexts, is unclear

How, exactly, the proteins or the composition of the blood affect the process of ageing is yet unclear. However, the result of the American scientists is in line with previous studies, which were also already corresponding correlations close to.

So colleagues from the University of Stanford have already shown in mice that blood transfusions from young animals have a positive impact on the health and the aging process of older.

Blood tests could indicate premature aging and the associated risks

Until now, Doctors could draw no consequences for the treatment of people. However, the Stanford researchers believe that the mechanism between blood and aging for promising, could recognize a physician on the Basis of which, in the future, but to test for specific proteins in the blood of the patient is examined and age-related diseases such as Alzheimer’s or cardiovascular disease earlier and risk-identify those patients.

Because what was particularly striking: people whose age was estimated on the basis of the protein concentration in the blood is significantly lower than their actual age, were unusually healthy for their age. From this, the doctors conclude: those Who have already in young years, a high proportion of certain proteins in the blood, which could be helped in the future, roughly corresponding to early, using preventive medication.

Until such testing could, however, be used to check the results of the scientists in further studies.
