The Department of Health has responded to warnings over routine dementia screenings.
It said there is "currently no benefit" in trying to diagnose people with dementia before they show symptoms of the condition.
Our preferred approach is for doctors to speak to patients that have symptoms such as memory loss, which could be caused by dementia. If dementia is suspected only then would further investigations take place. This approach is not the same as screening.
We do, nonetheless, encourage an early diagnosis and referral for those who show symptoms.
