4 years after the animal hero’s Alzheimer’s diagnosis, Jack Hanna’s family provides a tragic update.

A terrible update on the state of renowned zookeeper Jack Hanna’s fight with Alzheimer’s has been provided by his family.

After receiving a dementia diagnosis in October 2019, the host of the animal TV program “lived in fear the public would find out,” according to sources. In the end, the family of the 76-year-old had no choice but to inform the public of his passing in 2021.

Sadly, they now claim that Hanna’s Alzheimer’s has advanced to the point where he no longer recognizes most of his family and doesn’t know he has the disease.
