What We Know About Jay Leno’s Wife’s Dementia Diagnosis

Sadly, in January 2024, it was revealed that Mavis Leno was battling dementia. Her diagnosis was unveiled in court documents filed by Jay Leno in the Los Angeles County Supreme Court. Jay is petitioning for conservatorship for his wife’s estate. The paperwork, which was obtained by Entertainment Tonight, included a doctor’s report from November 2023. The petition shared that Mavis “has been progressively losing capacity and orientation to space and time for several years” and “her current condition renders her incapable of executing the estate plan.” This information is what led Jay to seek conservatorship, which will allow him to manage his wife’s personal and financial affairs, as she is incapable of making those decisions on her own.

Jay stepping into a caregiver role is not surprising, considering that Mavis was by his side during his own health struggles. In November 2022, he was burned in a garage fire, which required several surgeries, and months later, in January 2023, he had a motorcycle accident, leaving him with several broken bones.
