This study investigates the theory that suicide incidence rates in Europe increase in proportion to age, with notably higher rates after age 75, with the exclusion of Finland, Norway, Poland, and Scotland. The risk of suicidal thoughts was not found to be different in demented versus non-demented oldest-old subjects. In conclusion, the findings point out that dementia by itself must not be considered as a risk factor of possible suicidal ideation among the healthy oldest olds.
