If not, here is a summary of what I know. Doctors have no treatment for TIA's at this time. What happens is a chain of chemical reactions that takes many hours, sometimes even days. This chemical reaction causes the brain cells to inflame and burst-thereby permanently killing them. I will tell you what I learned on each of these three points.
Magnesium relaxes the muscles.
This part will sound very wierd to you. But, I promise you this has saved my friends life many times as he was recovering from TIA's. Surprisingly the only chemicals available at this time which do this and treat the inflamation are natural products you can buy at your local health food store. He should do this now, this very minute. It will salvage cells that are now on the verge of bursting.
