According to the new study, your brain may start again or not at a dramatically faster rate when you turned 65, it does depend on which version of a particular gene you have.
Through the study, scientists say that a particular version of the gene which appears to control the speed at which the brain ages, and it may provide a protection against the age-related neurological diseases, along with dementia.
The gene, which is known as TMEM106B, comes into the action at the age of 65. And not after so long, compared to the people who have working copies of this gene, the people with bad copies of this gene will have a brain that looks 10 to 12 years older at the same age, scientists suggested.
Rhinn and Abeliovich explained- What we have in the new study is that the TMEM106B gene underlies how well seniors maintain their perceptional abilities and those genes are more broadly associated with brain age.
TMEM106B gene, control the inflammation and neuronal loss in the brain. Also, the gene or allele have two forms: The first form is concerned with an increased rate, or risk, of brain aging, and the second one is, allele provides protection and is thought to intercept such as accrual of aging.
Well, trough what Rhinn said- All of us have two copies of the gene. Around 30% of people have two risk alleles among the general population, 50% of population contain one risk allele and one protective allele, and remain 20% have two protective alleles. He also added, the effect of the TMEM106B risk allele is additive, in the sense that the brain of the aged people who contain copies of the risk allele ‘looks’ five years older than the people with only one copy of risk allele, and the people who have one copy of risk allele ‘look’ five years older compared to the people with no risk allele.TMEM106B regulates the systematic response to age-associated stressors in the human brain, it’s still one of our undoubted hypotheses.
