Hi, I'm a student starting my third year next year. For my dissertation, I want to write a paper on elephants and mental degeneration such as dementia. Do you know of any elephants that act strangely, showing the same symptoms as humans do for dementia? Have you heard of it before, if so where? What are your thoughts on this topic? Even better, if you know of an elephant that has been tested or you believe has dementia? Any information would be greatly appreciated!!
