DOLPHIN's brains do develop Alzheimer's Disease, according to new research from Oxford University.

It is the first study to find unambiguous signs of the disease in a wild animal.

A review led by Professor Simon Lovestone, an old age psychiatrist from Oxford Health NHS Foundation Trust, found that humans were almost unique in having Alzheimer’s Disease but they were not alone.

He said a common link between dolphins and humans was both lived long after they could have offspring and this may play an important role in the findings.
