An experimental drug, called ISRIB, has shown to reverse age-related mental decline in mice with just a few doses
"ISRIB's extremely rapid effects show for the first time that a significant component of age-related cognitive losses may be caused by a kind of reversible physiological 'blockage' rather than more permanent degradation," said Susanna Rosi, PhD, Lewis and Ruth Cozen Chair II and professor in the departments of Neurological Surgery and of Physical Therapy and Rehabilitation Science.
Findings were published in the open-access journal eLife and shows the rapid restoration of cognitive abilities in aged mice. In addition to the rejuvenation of brain and immune cells that improve brain function.

"The data suggest that the aged brain has not permanently lost essential cognitive capacities, as was commonly assumed, but rather that these cognitive resources are still there but have been somehow blocked, trapped by a vicious cycle of cellular stress," added Peter Walter, PhD, a professor in the UCSF Department of Biochemistry and Biophysics and a Howard Hughes Medical Institute investigator. "Our work with ISRIB demonstrates a way to break that cycle and restore cognitive abilities that had become walled off over time."
