A large number of people with Alzheimer's are misdiagnosed if their symptoms do not initially include memory loss, research has revealed, no doubt affecting many with long term care plans.
More than half of sufferers under the age of 60 are misdiagnosed with other conditions if their symptoms are atypical of the condition, according to research published in journal Neurology.
Moreover, 47 per cent of people with Alzheimer's who did not originally describe memory loss as a symptom continued to be misdiagnosed with other brain conditions until death.
This group reported symptoms such as blurred vision, slurred language and a change in behaviour in the early stages of the condition.
Albert Llado, study author, said: "Biomarkers of Alzheimer's disease and other disorders are needed for us to better recognise, diagnose and treat early onset Alzheimer's disease sooner to improve the quality of life of these patients."
Meanwhile, eyecare specialist Optos has said that an eye test could potentially be used to diagnose individuals with Alzheimer's disease.
