New revelations emerged Tuesday in the unfolding case of missing radio personality Casey Kasem:

1. He doesn’t just have Parkinson’s.

Kasem’s daughter learned from medical records this week that her father has Lewy body dementia. The Mayo Clinic:

Lewy body dementia, the second most common type of progressive dementia after Alzheimer’s disease, causes a progressive decline in mental abilities.

It may also cause visual hallucinations, which generally take the form of objects, people or animals that aren’t there. This can lead to unusual behavior such as having conversations with deceased loved ones.

In Lewy body dementia, protein deposits, called Lewy bodies, develop in nerve cells in regions of your brain involved in thinking, memory and movement.

According to the Lewy Body Dementia Association, an nonprofit advocacy group, the disease affects 1.3 million people in the United States. According to the association’s Web site, Lewy body dementia denotes “both Parkinson’s disease dementia and dementia with Lewy bodies.”

2. Jean Kasem has her own tale to tell.

Though Kasem’s wife has not surfaced, she said in November that Kasem’s children’s allegations are unwarranted. CNN:

“These children single-handedly and irreparably shattered the lives of their father, his wife and youngest daughter, the calm of their home and their neighborhood by engaging in uncalled for public demonstrations and personal attacks in the media,” she said in court papers, according to CNN affiliate KCBS. “They are doing so with a professionally orchestrated media and legal campaign that has disgraced their father and vilified their stepmother.”

The children “falsely claim that their stepmother is wicked and is keeping her husband prisoner in his home behind closed doors and that they no longer have access to him through no fault of their own,” she added. “… For reasons they know all too well, their presence at this state would be toxic and extremely distressing for Casey, Jean and their daughter, Liberty, who have had enough of their cruelty.”

3. Be on the lookout.

Though a judge ordered adult protective services to locate Kasem, no details have emerged about his whereabouts after Craig Marcus, a lawyer representing Jean, said he “was no longer in the United States.” Kerri Kasem on “The Today Show”:

“I said, ‘Dad, we’re going to be back really soon,’ and he said, ‘When?’ That’s the last time I saw him, and then that night he was taken from the facility,” Kerri Kasem said. “What he’s going through right now. I mean, he’s a sick man. It must be horrible for him. If anybody’s seen him, if anybody knows his whereabouts, please call the police. Please help us find our dad.”
