The news of Phil Robertson’s death in May 2025 was accompanied by the confirmation that his passing was due to complications from Alzheimer’s disease. This diagnosis and his subsequent health decline had been a private struggle for the Robertson family before they chose to share the difficult news with the public.

The Health Decline and Alzheimer’s Diagnosis

The first public acknowledgement of Phil’s serious health issues came in late 2024. His son, Jase Robertson, revealed on the family’s popular podcast, *Unashamed with the Robertson Family*, that his father had been diagnosed with Alzheimer’s disease. Jase noted at the time that his father was in the “early stages” of the disease, but also shared that Phil was “really struggling” and facing a steady decline.

Beyond the neurodegenerative effects of Alzheimer’s, Jase also disclosed that his father was battling another, unspecified blood-related disease, which was further complicating his health. This combination of serious illnesses led to a rapid deterioration in his overall well-being, as Jase candidly stated that his father’s health was “not good.”
