Researchers at Cedars-Sinai Medical Center in Los Angeles, California, studied and analyzed human eyes and brain tissue from 86 deceased patients who were diagnosed with either Alzheimer's disease or mild cognitive impairment before their death.

The researchers also compared samples of people with normal cognitive function to those with early-stage symptoms and to those with late-stage Alzheimer's disease.

Researchers have found that the retinas of patients with mild cognitive impairment and Alzheimer's disease contain excess amyloid beta 42, a protein that forms the "plaques" that accumulate in the brains of people with Alzheimer's disease.

"We found an accumulation of highly toxic proteins in the retinas of patients with Alzheimer's disease and mild cognitive impairment, causing severe cellular degeneration," said Dr. Yosef Corono, a research fellow in the Department of Neurosurgery at Cedars-Sinai.

Changes were also found in patients who had no or very mild cognitive decline, indicating that retinal tests can help in early diagnosis.

It will be recalled that in


, Poland , a man pulled his dead mother's body out of the grave and lived with it for 13 years.

The corpse was lying on the sofa, on the newspapers.

This became known in February 2023.
