Symptoms of Alzheimer's affecting patient's memories could be reversed, new research from MIT indicates. It might be possible to break down the genetic blockades inside the brain which cause memory loss from Alzheimer's, a study published in Cell Reports suggests. So far, the theory has only been tested on mice but lead author Li-Huei Tsai is hopeful that eventually, it could be successful in reversing the symptom in humans. Memory loss is a form of cognitive decline which occurs when the enzyme HCAC2 compresses the brain's memory genes until they are rendered useless which, in turn, leads to forgetfulness and difficulty forming memories. Whilst the obvious solution is to simply block HCAC2
