There are some key traits to spot when identifying whether or not a loved one needs psychiatric care.
Ian Weatherhead, lead nurse for Admiral Nursing Direct, said those concerned about the effects of dementia in a loved one should look in their cupboards to see what type of food they are buying.
He explained that if the food is mouldy or out of date then this is a good indicator of memory impairment.
Other indicators include when a person becomes more withdrawn and ceases to socialise like they may have done in the past.
However, it is not as simple as saying those displaying such symptoms have Alzheimer's disease or some other form of dementia, Mr Weatherhead said that cognitive impairment conditions are complex and need close medical scrutiny.
"It is important that we rule out other things that could be easily treatable to improve somebody's life before we make a formal diagnosis of dementia," he stated.
