Welcome to NT Nick,

Unfortunately, being knocked unconcious, even for a short period, can be indicative of a serious brain injury and can greatly decreases the odds of making a "full" recovery. As Mark has told you, adding a second concussion made matters worse.

If you're a varsity athlete, I know that you're under tremendous pressure to keep playing. The team doctor, sadly, may not be acting in your best interests and your brain is vastly more important to your future than your scholarship money.

If you're not under the care of a neurologist and a physical medical specialist, you should be. Have you had an MRI?

As for your homework issues, you should get all the extra help to which you are entitled. While you're recovering, what you absolutely don't need is to be staying up half the night trying to write papers and feeling stressed over exams. A lot of brain injured folks end up dropping out when a little assitance would have seen them through. Contact your college's disabilties officer for information.

Before you get extra help (tutor, additional time for assignments, etc...), you may be required to undergo a neuro-psychological examination. It's essentially a battery of verbal, oral and motor skills tests designed to reveal how your brain is really functioning. Frankly, it's the best thing that you could do. Getting a clear picture of what's going on helps impress upon people the importance of taking care of their brain.

Best of Luck!
