Dementia is a disease and is not part of the normal ageing process - but some of its early signs can often be confused with growing old.
Memory loss is one of the most obvious symptoms, but dementia - which affects the brain - also displays a range of other warning signs. Some of these can appear years before diagnosis, which are often mistaken as natural signs of old age.
With Dementia Action/Awareness Week underway until May 22, it's important to be aware of lesser-known symptoms. Difficulty finding the right words, behavioural change and struggling to concentrate could also indicate dementia, according to Alzheimer Scotland’s Head of National Services, Jennifer Hall.
