My brothers ended up getting ahold of my ds and the top screen has scratches on it and the touch screen is lightly damaged. So i was wondering if it's possible to repair them.

Screen protectors are always a good idea. Also it may be possible to buy/import a replacement screen to replace the screens yourself, though youd have to know what you were doing. Could also try some glass/plastic scratch repair polish and try buff out the scratches.
