Alzheimers not being treated (with respect)

Major reports flying through all UK newspapers about the treatment, or lack of, to Alzheimers patients. The NHS feels the cost of drugs such as Donepezil, Rivastigmine, and Galantamine are too much to give to these necessary users for the little effect they seem to achieve.
I know first hand how they can enhance a sufferer's life and give them back a little dignity and little chance of being independant.
If the difference between taking the medication and not taking the medication means complete loss of independence and dignity then surely the medication must account for something in their lives. They may not acknowledge it and the effects may appear to be minimal however they are key drugs if they do the right job. These sufferers may be incapable of working or being thankful for the drugs yet see their smile when they achieve even the smallest things and surely the expense is worth it.
In our cost cutting culture, because these drugs do not appear to make a life change completely around and help a person return back to normal thinking after suffering from alzheimers, those with the power think these people do not need them. Absolute rubbish!
Even the smallest amount of independence they achieve lesson the burden on carers and give them a sense of belonging in life, in their homes and in their communities
