20 years ago, my father had stroke when he was 69 y/o. Being heavy smoker, first three weeks in hospital were very difficult, he was blind, not able to move/talk, having crisis on 7th, 14th, 21st day after stroke incident. Days in between, he would be smoking, (Bosnia in the 90s, patient could smoke in the hospital) it was really a battle to get him off.
Things gotten really bad, family thought we lost him. The most amazing thing, friends recommended to take Russian pills Aminalon 2x 250mg with each meal, so 3 times a day. We were told, as much as he recovers in next 18 months will be the best he can ever get. To my amazement, 2 months after the stroke, he was released from hospital, able to move, but having difficulties with orientation. He wouldn't know the way around, not knowing where kitchen or bedroom is. He did stop smoking, but kept taking Aminalon like religious thing. 6 months later, he was able to go to the city downtown by himself, not getting lost, finding way back to the apartment.
I lived with him for the first 1.5 years. After that, he was on his own, and lived for 12 years in great health after the stroke. He was active till the last day, he died in his sleep.
When I looked up Aminalon, I discovered it's called GABA here in the west, but never heard anyone suggesting for stroke patients. Back home, it's been known to help recover brain function and memory. One year after stroke, 50 y/o actor was able to get back to theater, memorizing script better than any young guy, thanks to Aminalon aka GABA.
Wish all the best, hope for Ted's recovery.
