Earlier diagnosis of Alzheimer's disease is "essential" to defeat dementia in expat health insurance customers and other people.
This is the view of Dr Marie Janson, director of development at the Alzheimer's Research Trust, who noted that it is difficult to diagnose the condition because there is no definitive test for it yet.
"The symptoms can appear slowly and can be similar to other conditions. We need better ways to diagnose the condition as well as improved training for doctors and greater awareness among the public," she pointed out.
If treatments for other diseases, such as cancer, are more successful if applied early, the same is likely to be true for dementia, Dr Janson added.
Her comments follow the trust's research showing 820,000 people in the UK alone are affected by Alzheimer's, which costs the country £23 billion each year.
Expatriate health insurance policyholders who suspect they or a loved one is showing signs of dementia could find that earlier medical treatment is more effective.
