BBC doctor says dementia study found symptom starting in ear 10 years before memory loss

Résumé détaillé

On BBC Morning Live NHS Dr said researchers found symptoms like tinnitus before people got Alzheimer’s disease

A BBC health expert has explained how a new study found evidence that dementia may affect one part of the body years before major memory loss starts. Published in Alzheimer’s & Dementia, the research by scientists at the University of Oulu and the University of Eastern Finland shows that people who develop early-onset Alzheimer’s disease, diagnosed before age 65, may have different health problems as long as 15 years before their diagnosis.

On BBC Morning Live, Dr Oscar Duke explained the findings and said it even found links to very common conditions like tinnitus. He told hosts Rav Wilding and Louise Minchin: “This is a study from Finland, and what they did they were looking at particularly people with early-onset Alzheimer’s disease. So that’s under the age of 65.

“They looked at 407 people in that category and compared them to 4,000 normal people without that condition to see what sort of symptoms might have been linked or associated to Alzheimer’s disease.

“Yes, they did find that there’s a small difference, but a statistically significant one in this study in terms of association with problems like hearing loss and tinnitus - that sort of ringing high-pitched frequency noises within your ear.”

Dr Duke said that medical research has been linking hearing issues with Alzheimer’s for some time: “There’s been a lot of association between hearing loss and dementia. it’s very difficult the experts still argue about because no one really knows - whether there’s a direct link generally in life, whether there’s a similar process that’s causing both hearing loss and dementia so it’s not one causing the other but just something else causing both of them.
