“He has been held in the warm embrace of family and friends, surrounded by live music, prayer, tears, laughter, and the kind of profound emotion that only he could inspire after a lifetime of devotion to us all,” the statement continued. “We will forever cherish the peaceful ease and reflection on his face, an enduring reminder of his invincible grace.”

Alzheimer’s disease is the most common form of dementia, the loss of memory, problem-solving and thinking abilities. It is a progressive disease that begins with mild memory loss and ultimately has no cure, according to the U.S. Centers for Disease Control and Prevention.

Lewy body dementia is a type of dementia that can cause complications with movement, behavior, thinking and mood, according to the CDC.

It is unclear when Stewart was diagnosed with Alzheimer’s and Lewy body dementia.
