Last night I made a suggestion that perhaps if we got him to learn a new language, or perhaps reignite some of the French he learned many years ago, he may well learn to speak properly. It was reported back to me, that it did indeed work and for the first time in two years, my friend spoke coherently.

That's wonderful news :) What made you think to try it? I hope your friend continues to improve 🙌

Those of us with our health should be truly thankful...
