A recent study by a drugs company found that the amount of money spent on a specific pill used for the treatment of Alzheimer's disease in the UK showed wide regional variation. Alzheimer's is a condition associated with the ageing process. In some areas the expenditure was as low as £1 per head of the population over 65 whereas in others it was as high as £10 per head. These pills are the most effective treatment for this condition that is currently available. Therefore, this is another example of 'post-code lottery' where the effectiveness of treatment for a health condition will depend upon where you live.
