Neurological condition
Life expectancy with dementia
Dementia describes a group of conditions, including Alzheimer’s disease, that affect memory, thinking, and the ability to carry out daily activities.
What the research suggests
Survival after a dementia diagnosis varies considerably, commonly reported in research as several years, with the range strongly influenced by age at diagnosis, the type of dementia, and general health. Younger people at diagnosis and those with fewer other conditions tend to have a longer outlook.
What changes the outlook
Good management of other health conditions, physical activity, social engagement, and treating reversible contributors all support quality and length of life. Outcomes are highly individual.
