A march will take place in York on Friday to protest against drug restrictions during the early stages Alzheimer's disease.
Hundreds of campaigners are expected to take part in the event, to fight a decision by the National Institute for Health and Clinical Excellence (Nice) to limit the prescription of donepezil, galantamine and rivastigmine to patients whose condition has deteriorated to "moderate".
Campaigners say that the drugs cost as little as £2.50 per patient per day and that it will therefore not be massively cost cutting to restrict them.
Gill Myers, branch manager of the Selby and York Alzheimer's Society, has appealed to the public to "join us in our battle against the decision that stops people in the early stages of dementia receiving the vital drugs on the NHS and help us raise awareness about this key issue", reports the York Press.
Petitions will be given to the local members of parliament, Hugh Bayley of York and John Grogan of Selby.
