Type 2 diabetes and dementia are increasing in prevalence, as they are both
associated with ageing and the population as a whole is living longer. Individuals who
have both conditions will have very complex needs. People with diabetes are more
likely to develop dementia than the general population. This may be due to possible
genetic links; however, both conditions share common lifestyle risk factors. The
diagnosis of diabetes may be delayed in an individual with dementia for a number
of reasons. Conversely, the development of dementia in someone with diabetes has
significant implications for self-management. The focus of treatment for people with
diabetes and dementia is safety, particularly avoidance of hypoglycaemia, as well as
maintaining independence and use of self-management skills as far as possible. The
staff caring for people with diabetes and dementia should be appropriately trained.
