Arisept is the proven allopathic remedy to keep the person, as it was explained to me, remembering to wash themselves and eat etc. It is very expensive , over £1000 per patient per year and is not given by all Health authorities. There are stringent tests every 3 months, to check that it is still working, in the form of simple questions , like where are we, what is the date, who is the Prime minister etc.

Re your husband - tell him that herbal Gingko Bilboa is meant to be a preventative!!
