Now, this is something that is more cutting edge, more inline with likely finding something to fix PTSD and other illnesses with the use of drugs short term, not long term.
This is currently being tested for illnesses such as Alzheimers and Parkinsons, however; the limits are endless where it may go. Basically, the safest way they are looking to activate these stems cells into creating new one's and fixing the brain itself, is through the use of a pill which will put the right combination of chemicals into the body to activate the stem cell growth within the brain, so basically without having to have brain surgery, this is the safest more effective way.

They have found it, they have activated it, now they are just looking at how to do it easier with a pill, and allow that to trigger the growth for new stem cells, to replace the old dead one's or damaged one's that cause brain diseases and issues. This research will give a whole new meaning to mental health cure on the horizon, as the pill basically tricks the body into repairing itself, reversing the damage caused to cells by a degenerative disease.

As PTSD is a neurological imbalance, hopefully this is a more effective way to simply repair damaged cells within our brain, forcing growth in other areas to wipe it out, and be left with nothing more than merely trauma to heal.
