On Wednesday, the family of television wildlife advocate “Jungle” Jack Hanna updated fans with some heartbreaking news.

In a Facebook post, the Hanna Family shared a letter to update followers on Jack Hanna’s health. Jack’s daughters explained that while doctors initially diagnosed their father with dementia, the family now believes the 74-year-old has Alzheimer’s disease. They wrote:

“Today, we reach out to share some personal Hanna Family news. Doctors have diagnosed our dad, Jack Hanna, with dementia, now believed to be Alzheimer’s disease. His condition has progressed much faster in the last few months than any of us could have anticipated. Sadly, Dad is no longer able to participate in public life as he used to, where people all over the world watched, learned and laughed alongside him.”


Jack’s daughters also highlighted their father’s incredible legacy. Jack was the executive director of the Columbus Zoo Aquarium from 1978 to 1992. Even after her left the position, Jack remained a spokesperson for the zoo up until 2020. Additionally, Jack “engaged with millions of households” through television and media appearances. Many fans recognize Jack from programs such as Animal AdventuresWild Countdown, and Into the Wild. 

“While Dad’s health has deteriorated quickly, we can assure you that his great sense of humor continues to shine through. And yes – he still wears his khakis at home,” the Hanna family wrote.
