Two recent studies highlight the relationship between age and dementia, one finding that people with dementia survive an average of six years after their diagnosis, regardless of how old they are, and another reporting that the prevalence of dementia increases with age, even in the oldest population. Data from the studies was presented at the 2018 Alzheimer’s Association International Conference recently held in Chicago. Patients with dementia have a shorter life expectancy than the general population. Survival time after diagnosis varies considerably, with median survival times between three and 12 years. This variation could be due to many factors, including the type of dementia, patient characteristics and change in management over time. Researchers at VU University Medical Center in Amsterdam analyzed the clinical records of 4,495 people enrolled in the Amsterdam Dementia Cohort between 2000 and 2014 who had subjective cognitive decline, mild cognitive impairment, or any type of dementia. Their findings were published in the study, "Survival in memory clinic cohort is short, even in young-onset dementia," in the Journal of Neurology, Neurosurgery & Psychiatry. Patients who had frontotemporal lobar degeneration — degeneration of the frontal and anterior temporal lobes in the brain — survived a median 6.4 years. Those with Alzheimer’s disease survived a median 6.
