The brain of a chimpanzee estimated to be 68 years old, the oldest reported so far, has been examined. Pathological analyses revealed the formation of mild tau‐positive neuritic clusters and cytoplasmic α‐synuclein aggregates, in addition to severe cerebral amyloid angiopathy and diffuse plaques, but no tangle lesions were observed.
