Mark, thanks for your response. You have been SO helpful. Can you clarify 2 more things for me?

I know very little about PCS and find the internet to be confusing.

1. Is it possible for someone to suffer both retrograde and antegrade amnesia?

2. Can you clarify what you said by: "There is no way to prognose how long his recovery will take. You did not say how long ago he suffered the concussion. Most heal to their maximum level within 45 days. Those that don't fit the prolonged Post concussion Syndrome category. Then the time line can vary greatly."

Owen suffered his concussion 2 weeks ago. Does he not qualify to have PCS? What is prolonged PCS?
