New technology could help early diagnosis of Alzheimer's disease

About 6.5 million Americans are living with Alzheimer’s disease.

There is no cure, very little cure, and it can only be found through a costly scan or painful spinal tap.

But now researchers are testing new devices that make testing easier. This means that it may lead to early diagnosis.

John and Sylvia Whitley play Wordle every day. Letters come easily today, but this couple knows it won’t last. started.

“Remembering names became more and more difficult over time,” says John.

“I met a dear friend,” Sylvia recalls. “I saw her several times during her week, but I didn’t get her name.”

The couple underwent a spinal fluid test at Emory University. Sylvia had markers of Alzheimer’s disease. John didn’t. However, after 58 years of marriage, we learned that we both struggled with memories. They are both currently undergoing pet scans. John was eligible to participate in a clinical trial testing a new method of detecting early signs of Alzheimer’s disease so that patients could begin treatment if needed.

RetiSpec is an investigational device. This is a special camera that can take 100 superimposed images of the retina.

“Then they have artificial intelligence that can look at those images and see the buildup of amyloid plaques on the retina,” says Dr. Marshall.

Researchers are testing the accuracy of RetiSpec. Previous studies have shown RetiSpec to be 80-90% accurate.

“If there’s anything we can find for us, or help others, we’d love to be a part of it,” Sylvia says.

“It’s good for me and good for others,” John says.

Sylvia wasn’t eligible for the RetiSpec test, but doctors are actively looking for other clinical trials she can participate in, she said. The researchers say their goal after FDA approval is to install RetiSpec cameras in ophthalmologists’ offices to make the technology more widely available.

Topic: Does RETISPEC detect early Alzheimer’s disease?

BackgroundApproximately 5.8 million people over the age of 65 in the U.S. have Alzheimer’s disease, with 80% over the age of 75 and an estimated 60-70% of the 50 million people with dementia worldwide have Alzheimer’s disease It has been. There are no known treatments that can cure Alzheimer’s disease or even alter the diseased brain processes. (Source:

Diagnosing: Alzheimer’s disease is a brain disease that causes gradual deterioration of memory, thinking and reasoning. Warning signs about memory include amnesia that can interfere with daily life, difficulty completing familiar tasks, difficulty understanding visual images and spatial relationships, and even language problems when speaking or writing. There are new issues. Other symptoms of Alzheimer’s disease include getting lost in familiar places and misplacing belongings or leaving them in unreasonable places. (Source:

New technology: RetiSpec is developing a new technology that detects possible Alzheimer’s disease years before symptoms appear. No current test can confirm an actual diagnosis of Alzheimer’s disease, but RetiSpec’s technology uses the device to perform a simple eye scan. It is used to identify the presence of eye disease biomarkers. The technology also uses hyperspectral imaging technology and AI. A driven algorithmic method for analyzing biomarker data. (Source:
