Early Alzheimer’s disease could be diagnosed through eye exams, new study suggests
Alzheimer’s is a illness of the mind, normally recognized by MRI scans and a battery of different checks.
Researchers, nevertheless, have discovered that the human eye can present early indicators of this widespread type of dementia lengthy earlier than signs turn into obvious.
Researchers at Cedars-Sinai Medical Heart in Los Angeles, California, led the research, which was printed within the journal Acta Neuropathologica final month.
The researchers analyzed human eyes and mind tissue from 86 deceased sufferers who had been recognized with both Alzheimer’s illness or delicate cognitive impairment earlier than they died.
ALZHEIMER’S DIAGNOSES EXPECTED TO REACH NEARLY 13 MILLION BY 2050, SAYS NEW REPORT
The researchers additionally in contrast samples from individuals who had regular cognitive operate to those that had early-stage signs and to those that had late-stage Alzheimer’s.
The retinas of the sufferers with delicate cognitive impairment and Alzheimer’s illness, the researchers discovered, had an extra quantity of amyloid beta 42, a protein that kinds the “plaques” that construct up within the brains of individuals with Alzheimer’s.
Moreover, the retinas contained cells referred to as microglia, that are additionally related to development of the illness.
‘Extremely poisonous proteins’ discovered within the eyes
“We found the buildup of extremely poisonous proteins within the retinas of sufferers with Alzheimer’s illness and delicate cognitive impairment, inflicting extreme degeneration of cells,” mentioned Dr. Yosef Koronyo, analysis affiliate within the Cedars-Sinai Division of Neurosurgery and first writer of the research, in a press release on the Cedars-Sinai web site.
WHAT IS FRONTOTEMPORAL DEMENTIA, THE DIAGNOSIS BRUCE WILLIS HAS RECEIVED?
The adjustments had been additionally detected in sufferers who didn’t show any cognitive decline or had solely very delicate indicators, indicating that retinal checks may assist allow early prognosis.
Outcomes may level to earlier testing
This research is probably the most complete evaluation of the human retina by way of the way it pertains to the brains and cognitive features of Alzheimer’s sufferers.
That is in accordance with Maya Koronyo-Hamaoui, PhD, professor of neurosurgery, neurology and biomedical sciences at Cedars-Sinai, in a press release.
“These findings might finally result in the event of imaging strategies that enable us to diagnose Alzheimer’s illness earlier and extra precisely, and monitor its development non-invasively by wanting by the attention,” mentioned Koronyo-Hamaoui, senior writer of the research.
FIRST DRUG PROVEN TO SLOW ALZHEIMER’S WON’T BE AVAILABLE TO MOST PATIENTS FOR SEVERAL MONTHS
Greater than six million People at the moment have Alzheimer’s, in accordance with the Alzheimer’s Affiliation.
The illness is anticipated to have an effect on 12.7 million folks by 2050 because the inhabitants ages.
“The inhabitants of individuals age 65 and older is anticipated to develop from 58 million in 2021 to 88 million in 2050,” Nicole Purcell, DO, basic neurologist and senior director of scientific observe on the Alzheimer’s Affiliation in Chicago, Illinois, advised Fox Information Digital in an earlier interview.

FDA bans red food dye due to potential cancer risk
The U.S. Food and Drug Administration (FDA) has officially banned red dye — called Red 3, or Erythrosine — from foods, dietary supplements and ingested medicines, as reported by the Associated Press on Wednesday.
Food manufacturers must remove the dye from their products by January 2027, while drug manufacturers will have until January 2028 to do so, AP stated.
Any foods imported into the U.S. from other countries will also be subject to the new regulation.
RED FOOD DYE COULD SOON BE BANNED AS FDA REVIEWS PETITION
“The FDA is taking action that will remove the authorization for the use of FD&C Red No. 3 in food and ingested drugs,” said Jim Jones, the FDA’s deputy commissioner for human foods, in a statement.
“Evidence shows cancer in laboratory male rats exposed to high levels of FD&C Red No.3,” he continued. “Importantly, the way that FD&C Red No. 3 causes cancer in male rats does not occur in humans.”
The synthetic dye, which is made from petroleum, is used as a color additive in food and ingested drugs to give them a “bright cherry-red color,” according to an online statement from the FDA.
The petition to ban the dye cited the Delaney Clause, which states that the agency cannot classify a color additive as safe if it has been found to induce cancer in humans or animals.
The dye was removed from cosmetics nearly 35 years ago due to potential cancer risk.

“This is a welcome, but long overdue, action from the FDA: removing the unsustainable double standard in which Red 3 was banned from lipstick but permitted in candy,” said Dr. Peter Lurie, director of the group Center for Science in the Public Interest, which led the petition effort, as reported by AP.
Dr. Marc Siegel, clinical professor of medicine at NYU Langone Health and Fox News senior medical analyst, applauded the FDA’s ban.
“It was a long time coming,” he told Fox News Digital. “It’s been more than 30 years since it was banned from cosmetics in the U.S. due to evidence that it is carcinogenic in high doses in lab rats. There needs to be a consistency between what we put on our skin and what we put into our mouths.”
“There needs to be a consistency between what we put on our skin and what we put into our mouths.”
Siegel said he believes the FDA’s decision could be tied to the incoming new head of the Department of Health and Human Services, Robert F. Kennedy Jr.
“They knew it would have happened anyway under RFK Jr.,” he said. “It is already banned or severely restricted in Australia, Japan and the European Union.”
The food additive also “drew kids in” to a diet of empty calories and ultraprocessed foods, Siegel added.
“It has also been linked to behavioral issues in children, including ADHD.”
Nearly 3,000 foods are shown to contain Red No. 3, according to Food Scores, a database of foods compiled by the Environmental Working Group.

The National Confectioners Association provided the below statement to Fox News Digital.
“Food safety is the number one priority for U.S. confectionery companies, and we will continue to follow and comply with FDA’s guidance and safety standards.”
The petition to remove Red No. 3 from foods, supplements and medications was presented in 2022 by the Center for Science in the Public Interest and 23 other organizations and scientists.

As bird flu spreads, CDC recommends faster 'subtyping' to catch more cases
As cases of H5N1, also known as avian flu or bird flu, continue to surface across the U.S., safety precautions are ramping up.
The U.S. Centers for Disease Control and Prevention (CDC) announced on Thursday its recommendation to test hospitalized influenza A patients more quickly and thoroughly to distinguish between seasonal flu and bird flu.
The accelerated “subtyping” of flu A in hospitalized patients is in response to “sporadic human infections” of avian flu, the CDC wrote in a press release.
ONE STATE LEADS COUNTRY IN HUMAN BIRD FLU WITH NEARLY 40 CONFIRMED CASES
“CDC is recommending a shortened timeline for subtyping all influenza A specimens among hospitalized patients and increasing efforts at clinical laboratories to identify non-seasonal influenza,” the agency wrote.
“Clinicians and laboratorians are reminded to test for influenza in patients with suspected influenza and, going forward, to now expedite the subtyping of influenza A-positive specimens from hospitalized patients, particularly those in an intensive care unit (ICU).”
LOUISIANA REPORTS FIRST BIRD FLU-RELATED HUMAN DEATH IN US
The goal is to prevent delays in identifying bird flu infections and promote better patient care, “timely infection control” and case investigation, the agency stated.
These delays are more likely to occur during the flu season due to high patient volumes, according to the CDC.

Health care systems are expected to use tests that identify seasonal influenza A as a subtype – so if a test comes back positive for influenza A but negative for seasonal influenza, that is an indicator that the detected virus might be novel.
“Subtyping is especially important in people who have a history of relevant exposure to wild or domestic animals [that are] infected or possibly infected with avian influenza A (H5N1) viruses,” the CDC wrote.
In an HHS media briefing on Thursday, the CDC confirmed that the public risk for avian flu is still low, but is being closely monitored.

The agency spokesperson clarified that this accelerated testing is not due to bird flu cases being missed, as the CDC noted in its press release that those hospitalized with influenza A “probably have seasonal influenza.”
Niels Riedemann, MD, PhD, CEO and founder of InflaRx, a German biotechnology company, said that understanding these subtypes is an “important step” in better preparing for “any potential outbreak of concerning variants.”
“It will also be important to foster research and development of therapeutics, including those addressing the patient’s inflammatory immune response to these types of viruses – as this has been shown to cause organ injury and death during the COVID pandemic,” he told Fox News Digital.
Since 2022, there have been 67 total human cases of bird flu, according to the CDC, with 66 of those occurring in 2024.
The CDC recommends that people avoid direct contact with wild birds or other animals that are suspected to be infected. Those who work closely with animals should also wear the proper personal protective equipment (PPE).
