My mom had a massive stroke 6 years ago. She is 63 now. As a result of the stroke she suffers mixed aphasia, which affected her speech and comprehension. I have been following this research for years now and I don't know what to believe

Did anybody tried this treatment for something similar to my mom's illnes?

On the other hand, I read that some people will go or went for "Another round" why another? one is not good enough?

I also read, that there are two options, one where the cells are injected directly into the brain, but is a lot more expensive. Did anybody did this? is worth to do the more expensive? I am really worried about making the right decision since we are going to sell an apartment to be able to do this, but if is worth it, I wont think twice

I will appreciate if people who says is a ripoff can explain exactly what the illness is, because it confuses other's. I read everywhere that the treatment is effective in SOME cases, not for all illnesses. So, to say that "it doesn't work", is a little vague

And whichone is better? Germany or Costa Rica?
Anything anybody can suggest about the treatment of patients like my mom is greatly appreciated

Thank you
