We all forget things as we get older. Mild memory loss is common in older adults and as long as it doesn't affect their daily lives, isn't usually a problem. But memory loss that gets worse and affects daily life may be a sign of dementia. Dementia can cause problems with memory and how well a person is able to think and plan.
