Researchers in Scotland have found the telltale signs of the disease in the brains of several dolphin species who washed up on U.K. beaches.

The brain changes could explain why some dolphins become stranded, as a group leader with these changes may become confused or lost.

The brains of three species of dolphin found stranded along the Scottish coast have shown the hallmarks of Alzheimers disease, according to new research, providing greater insight into the disease in species other than humans.

Dolphins, like people, are incredibly intelligent and social creatures. And also like people, they may be prone to the ravages of cognitive decline.

Investigators examined the brains of dolphins stranded in shallow waters for hallmarks of Alzheimer's disease and found that all of the aged animals had amyloid-beta plaques.

WEDNESDAY, Dec. 21, 2022 (HealthDay News) -- Groups of whales, dolphins and porpoises are regularly stranded in shallow waters around the coasts of the United Kingdom.

A new study has observed that the brains of some stranded dolphins display changes similar to those seen in human Alzheimer's disease.

Researchers found the brains of three species of stranded dolphins had classic biomarkers associated with human Alzheimer's disease. The findings add weight to the "sick leader" theory, where a group of healthy dolphins finds themselves in dangerously shallow waters after following a group leader showing signs of confusion.

According to Scottish researchers, dolphins may have Alzheimer's disease. Three species, including a bottlenose dolphin, a long-finned pilot whale, and another, were discovered to have the disease's symptoms.
