Cannabis reverses aging processes in the brain, study suggests: Researchers restore the memory performance of Methuselah mice to a juvenile stage -- ScienceDaily
Memory performance decreases with increasing age. Cannabis can reverse these ageing processes in the brain. This was shown in mice by scientists at the University of Bonn with their colleagues at The Hebrew University of Jerusalem (Israel). Old animals were able to regress to the state of two-month-old mice with a prolonged low-dose treatment with a cannabis active ingredient. This opens up new options, for instance, when it comes to treating dementia.

111 N.F.L. Brains. All But One Had C.T.E. - The New York Times
A neuropathologist has examined the brains of 111 N.F.L. players — and 110 were found to have C.T.E., the degenerative disease linked to repeated blows to the head.
Dr. Ann McKee, a neuropathologist, has examined the brains of 202 deceased football players. A broad survey of her findings was published on Tuesday in The Journal of the American Medical Association.
Of the 202 players, 111 of them played in the N.F.L. — and 110 of those were found to have chronic traumatic encephalopathy, or C.T.E., the degenerative disease believed to be caused by repeated blows to the head.

Daring Fireball: Neuropathologist Examined the Brains of 111 NFL Players; 110 of Them Showed Signs of C.T.E.
The New York Times...
I keep thinking change will come inevitably from the ground up — fewer and fewer parents are allowing their kids to play football each year. But at the high school level, participation only dropped by 2.5 percent from 2008 through 2015.

Brains of former football players donated to science are rife with disease | Ars Technica
The large case series doesn’t tell us much about the disease, but highlights risk.
Signs of a degenerative brain disease were widespread among a sample of donated brains of former football players, researchers reported Tuesday in the Journal of the American Medical Association.
The finding bolsters the connection between playing American football and developing Chronic traumatic encephalopathy (CTE), which is linked to repeated blows to the head and was first described in boxers. However, the large study provides little new information about the disease, its progression, or prevalence.

Brain cells found to control aging -- ScienceDaily
Scientists have found that stem cells in the brain's hypothalamus govern how fast aging occurs in the body. The finding, made in mice, could lead to new strategies for warding off age-related diseases and extending lifespan.
