Lesser-known warning sign of dementia that can appear in the eyes before any memory problems

Researchers have discovered slight changes in the eyes could provide an early warning sign for dementia. A study found that retinal scans can detect key changes in blood vessels that may provide an early indication of Alzheimer’s disease.

Dr Jørn Slot Jørgensen, leading ophthalmologist at Laser Eye Clinic London, told the Express : "Some people think that visiting an ophthalmologist is only necessary if you have an eye condition or need vision correction. However, this is a widespread misconception that also applies to medical situations in general.

"In fact, an ophthalmologist might be the first physician to diagnose a medical condition because the initial signs may appear in the eye."

The cruel illness is more common in people over 65, but dementia can affect anyone of any age. Common symptoms include memory loss and confusion.

According to Dr Jørgensen, the following symptoms could ring alarm bells early:

While vision changes can be the first warning signs, they don’t always appear first. The doctor shared that the onset of these symptoms can vary from person to person.

He said: "In some cases, these signs may be subtle and may not be immediately recognisable. However, in other cases, they may become noticeable enough to prompt further investigation.”

Once you start experiencing any changes or problems with your vision, it’s important to seek medical help. You should speak to your GP as soon as possible.

Regular visits to your optician are just as important, as the expert could detect potentially harmful changes before symptoms even appear. Furthermore, regular eye tests might help reduce your risk of the mind-robbing condition, Dr Allon Barsam, consultant surgeon and founding partner at OCL Vision previously told
