The results of a model depend, of course, on the assumptions used for the variables in the model. For example, Dr. Wimo and colleagues concluded, in another model, that treatment of dementia with an ACEI was cost neutral. A truly successful disease-modifying treatment would allow patients to remain at home, avoiding dementia-related long- term care costs. It is true, though, that any treatment that prolongs life among the non-productive aged does have a net cost to society. The issue is, what is the quality of life for those who are treated? Here the discussion devolves into even more speculation. We don’t have good measures of life quality among older people with memory loss.
