I have read the article on the BBC website about the PBT2 drug and there are certain facts that need to be borne in mind before we all start cheering. The drug may slow the progression of AD although all the research has been done on mice and trials on humans have not yet started. Assuming that all goes well the drug will not be available for humans until 4 years time.
This is too late for many of us, consider the ravages to be wrought on our loved ones in four years and ask yourself if it would be a blessing to have their detioration halted let alone slowed down.
In the past six years I have witnessed many false dawns and whilst I sincerely hope there is a cure in the offing it will be too late for Mary. Be realistic and do not raise your hopes too high.
