Another thing--Tokimune Takeda, the last Soke of Daito Ryu, had a serious stroke in his sixties. He was partially paralyzed, but was still able to perform Aikijujutsu.

Aikijujutsu or Aikido should work, as long as you have a teacher patient enough to work with you. In the case of Aikijujutsu, the techniques are meant to work even if you're injured, so I don't see why they wouldn't work in your case. Just be realistic in your goals.

Good luck.
