eddy,

The stem cell therapies with promise would not be much help for PCS. Nerve fiber regrowth and such other therapies that aim to restore nerve conduction will be the likely successes. The diffuse axonal injuries of PCS will require some miraculous drug that stimulates axonal repair. The problem is the amount of time it takes for axons to make proper connections once they start repairing themselves.

As you start understanding each individual symptom, it is likely you can find ways to limit when those symptoms manifest by altering your environment or efforts. We can refocus our brain's abilities into tasks and functions that are working by avoiding any tasks that will strain our brain's efforts.

A simple example is how I can focus on thought processes. It makes a big difference if I close my eyes while I try to process thoughts. By stopping the output of brain energy to the visual processing part of the brain, I can put that same energy into the thought process.

I used to be able to drive, eat, listen to the radio and read a map at the same time. Now, if I need to read a map, I need to have my wife stop the car (no motion stimuli), turn the radio off ( no auditory stimuli) and sit quietly while I put my brain into focus to read the map.

The simple concept is called "Stopping to think." We need to stop the other brain tasks so we can think.

As we start to master these systems of isolating brain processing power, we can regain many of our previous functions.

If talking with a person is a struggle, observe what your brain is trying to do. Is it seeing the visual background behind the person?
Is it distracted by other sounds? Does you shoe have a sore or tight spot that is distracting your brain?
Is your bladder telling you that you should find a bathroom?
Are you late for an event and the anxiety of getting to that event is distracting you from hearing the other person's voice?

There are often very simple reasons for the difficulty with the current task. We just don't have the experience to see the obvious cause of distraction or confusion. As we learn to recognize these distractions, we can develop the skills to overcome them.

Some of them are not able to be overcome. I cannot talk to someone when there is background voices. No matter how hard I try to focus on what they are saying, the distractions keep cutting in. So, I move to a different environment without the sound distractions or put the discussion off for a time when the distractions are not a problem.

btw, Your experiences with your doctors are par for the course. If they cannot image it or observe it with an EEG or such test, the brain injury does not exist. Yes, we all understand when they say it is all in our head. They just have their meaning wrong.

My best to you as you struggle to make sense of your brain.
