the greatest fear is what you are going through for your father.but dont worry.he will do great.
worry is a bad thing.okay so alzeihmers is a slow process sometimes and others it might progress.
what i suggest is you should keep up the will of your father.his well being is very much dependent on how he thinks how he is.
you also shoud be strong.
syrups should be of help that you already giving.physiotherapy
should give benefit.
hope it helps.
