The information provided by Science Alert reported the researchers' recent discovery, which found traces of the Alzheimer's in the brain of dolphins of three different species, when they were found lifeless after stranding outside the sea.
The strandings are also being analyzed, since the research warned about the possibility of the occurrence of the “sick leader syndrome”.

Frank Gunn-Moore, a neurobiologist at the University of St. Andrews in Scotland said the most common question in their profession is whether animals can also develop dementia.
According to recent research, there is a very large potential that it is not just humans who suffer from dementia.
Dolphins Found With Alzheimer's
Illness is a factor that can incapacitate the human mind, being more common in the elderly. It gradually affects the patient's memory and can lead to loss of communication and learning skills. It is not just a common forgetfulness, but all the basic needs of coexistence.
Marissa Vacher, a biologist at the University of Leiden, reported that about 20 dolphins had recently stranded. All were used for brain analysis in research on the possible presence of Alzheimer's in animals. Disease markers similar to those present in humans were found.
The researchers looked at three distinct species: white-beaked dolphin, long-finned pilot whale and common bottlenose dolphin.
All showed signs of old animals in their teeth and in the changing color of the tissues surrounding their brains. The lesions found in the animals' brains were similar to those seen in humans with the disease.
With regard to Alzheimer's, experts believe that loss of memory, sense of direction and other conditions may have harmed the route of this group of dolphins, taking them to a shallower level than the sea. Despite progress in research, scientists have not yet been able to confirm the diagnosis of the disease in animals.
Although the dolphins' cognitive processing levels were not more active, there is a possibility that the disease can progress in animals, especially considering the social and interactive characteristics of these animals. animals.
