The brain is an extremely complicated I think they may have found one mechanism or one part behind the cognitive decline in aging. I am certain there are several different processes that contribute to it and finding all of them and then mitigating those may have side effects in other parts of the brain. I have an extremely speculative and not based on science that the brain simply is not meant to function forever. We extend life in various ways, and we get better at it. Perhaps in a couple of decades people will live (be kept alive) for 100 years on average. (well those who live in a country where such medication and treatment is available and at some level affordable) But human evolution has not caught up with the prolonged life span since living that long has been an exception for 300.000 years and looking farther back in evolution probably millions of years
