Recalling the past could be the key to keep dementia at bay as revealed by a new study.

Dementia often means it's easier to recall older memories than remembering day to day events.

Older memories can help tap into positive emotions in the present and have strong sentimental value.

Spokesman for Alzheimer's Society, George McNamara said that a trip down memory lane could be a powerful way of communicating with a person with dementia, as reported by the Daily Express.

Experts believe this recognition allows patients to be able to find their way around their new surroundings with much more ease.
