“Old Timers” or Alzheimer’s disease affects the brain in many negative ways.

But, according to new research, “Alzheimer’s has been reversed in mice for the first time, raising hopes of a drug to combat the disease.”

This “reversal” was found by decreasing levels of an enzyme called BACE1, which reduced the levels of “amyloid plaques which are linked to Alzheimer’s.”

In the study, the mice were genetically engineered to develop Alzheimer’s after 75 days of age. Eventually, mice with lower levels of BACE1 showed vast improvement, with plaque cleared from their brain at 10 months old. This practically erased the disease from the animals’ brains, and increased overall cognitive function.

“Our study provides genetic evidence that preformed amyloid deposition can be completely reversed after sequential and increase deletion of BACE1 in the adult,” stated Professor Riquiang Yan, who led the study.
