1. Why does only a minority of concussion sufferers develop PCS? Most people that suffer a concussion report symptoms for only a few days - why do some people develop PCS?

2. From the portion of the concussion sufferers that develop PCS, why do some people take weeks to recover, other take months or years, while others have PCS for decades? Why is the recovery rate so different among PCS sufferers?

3. Does young age improve PCS outcome (better healing rate and extent)?

4. Can supplements help the brain physically recover, or they are like wearing glasses? I mean, can supplements aid in the recovery process, or they just temporarily mask your symptoms while you take them?

5. Some people here report having symptoms for 20+ years. That sounds like a very long time to have PCS. How come symptoms can persist for such long periods of time?

6. Is neuron loss the primary cause for PCS symptoms, or is it the loss of connections between neurons that is more problematic? Can certain supplements help rebuild connections between neurons, therefore increasing the brain's recovery capacity?
