The relationship between aging and disease: geriatric ideology and myths of senility.

An ongoing debate in gerontology concerns the relationship between aging and disease. Goodwin, as part of a discussion on the importance of geriatric ideology, argues that age-related disorders like senile dementia of the Alzheimer's type (SDAT) should be regarded as an aging process, while others suggest it is more appropriate to consider it as a disease. This paper comments on the arguments presented by Goodwin and develops these by providing a review of the underlying assumptions concerning aging and disease. The policy relevance and implications for future research are also outlined.
