Enzyme could help people ERASE traumatic memories

For people living with post-traumatic stress disorder (PTSD), erasing distressing memories is something that could only be dreamed of. But researchers believe they may have found a way of turning those dreams into reality. Scientists have pinpointed an enzyme in the brain that is critical in the storage of long-term memories. While the enzyme has only been studied in mice so far, the researchers are optimistic that it could be targeted to remove distressing memories in people with PTSD in the future. The enzyme, called acetyl-CoA synthetase 2, or ACSS2 'fuels' gene expression in the nucleus of nerve cells to turn on key memory genes after learning.
