I also expect outstanding reduction in false alarms. To answer your question though, eventually we reach a point where theres no doubt as to 2-73s affect and we blast off. Could be at this 6 month interim, but definitely by the end of the trial in november/December.
The Facebook group has anecdotal evidence of improvement for 8 of the 32 patients in the current trial. I believe the cognitive and functional improvements will be picked up by the MMSE and ADCS-ADL tests and the results will be unprecedented improvement for the patients currently in the trial.
