I have minimal encephalomalacia on temporal lobe and very minimal on frontal lobe. It is softening of the brain.

Many TBI patients have this and brain finds new pathways as much it can and some with this type of injury recover completely (or close to it). Basically nothing much to worry about.

Unfortunately, once injury to the brain has occured, neurons (brain cells) are lost and are not regrown.

Perhaps one day, stem cell therapy may prove helpful in this regard but for now there are no current treatments available to treat this type of brain injury and replace injured brain cells. (you can google it)
