I struggle to think any video games are not too graphic or fast, unless you have something simple like Mario or Tetris or the older keyboard based war games. Hand-held controller based shoot-em-up video games are likely too much.

The issue you need to consider is: What are your peak activity levels during the day ?

With school over, I suggest you take this time to reduce your peak stimulation level considerably. It may also be good to stop the amantadine as it does not show a healing effect but rather is just a support for some cognitive functions. If you are not doing school work, a break from the push from the amantadine may be worthwhile.

And, bed rest may be counter-productive. Some simple low stimulation activities may be just as good. The brain needs good blood flow to heal. Do you have access to a fishing pond or such ? I do 100 piece jigsaw puzzles online at http://zone.msn.com/en/jigsaw/defaul...Strip_2_Jigsaw and http://thejigsawpuzzles.com/

Nothing in the literature shows any interaction between amantadine and B-12 or fish oil. B-12 is needed for proper brain function. It would be worthwhile to add D-3. It has no interactions either.

So, rest from serious cognitive efforts, limit video games to simpler format games but keep active. Something life Frisbee golf would be good.

And,, give your brain time to heal. Try not to be anxious or frustrated as you wait for improvements.

My best to you.
