Critically speaking, it is a single study done by a private group. No peer reviews. No follow up as of yet. So I'm not about to hold my breath.
"Experts urged caution, warning that the drug had been tried on only a very few patients and, crucially, had not been tested against a placebo in a randomised controlled trial."
None the less, I almost started crying just thinking what it would be like to have my Nana recognize anyone from my family again. Even just one more time.
