Los Angeles (CNN) -- A request by Casey Kasem's children that a temporary conservator be appointed for their ailing father was denied by a judge on Tuesday.
Kasem's daughter Julie Kasem and her husband filed a conservatorship petition in a Los Angeles court last month, claiming the retired radio host "has been isolated from his daughters, friends and other family" by his wife.
Los Angeles County Superior Court Judge Lesley Green ruled Tuesday that Kasem, 81, was being well cared for by his wife, Jean Kasem.
"As my clients haven't had the opportunity to see their father for some months now, they were happy to learn through investigation of the court appointed expert and the probate investigator that their father was being physically well taken care of," said Andrew Katzenstein, the lawyer for Julie Kasem.
Kasem, who for decades hosted radio music countdown shows "American Top 40" and "Casey's Top 40," is suffering from Parkinson's disease and "may have early onset Parkinson's dementia," according to a court filing. He retired in 2009.
The children, who have been fighting with their stepmother, are hoping they can soon see their father, Katzenstein said. While they have not spoken to her, their lawyers are discussion a visitation plan, he said.
"Also they were happy that the judge focused her attention on the important issue of visitation," he said. "Mr. Kasem has a long strong and loving relationship with his adult children and we are continuing to try and reach resolution with the other side so visits can begin again."
Green will hold another hearing on December 20 to decide if she will appoint a permanent conservator.
Kasem has the "ability to shuffle short distances, but is mainly bedridden and requires the assistance of a wheelchair to move any distance," a court document said.
The petition claims that daughter Julie Kasem and her husband, Dr. Jamil Aboulhosn, have been unable to check on Kasem's health even though her father signed papers in 2007 giving them the power of attorney over his heath care in the event he was unable to make his own health decisions.
They "have been prevented from exercising their duties" by Jean Kasem, who has been married to the retired radio host for three decades, the filing contends.
"There is no communication between Jean and us and his daughters," brother Mouner Kasem said Saturday. "We have no knowledge of how he is, what he's doing, if he's better, if he's worse, and we're scared that we'll never see him again."
The petition claims Kasem's wife has refused to provide the children with the name of their father's primary care physician. That doctor would be consulted to determine Kasem's "ability to act on his own behalf," which is the question that would cause the health care power of attorney to take effect, it said.
Daughter Kerri Kasem said last month that her stepmother suddenly barred her sister, her uncle and some of Kasem's friends from seeing him about three months ago. She said she was perplexed by the decision.
"I don't get it, I don't understand it," said Kerri Kasem, who co-hosts the radio show "Sixx Sense" with Motley Crue's Nikki Sixx. "He has Parkinson's, and all the research we've done indicates socialization would help him."
CNN has reached out to get a statement from Jean Kasem, but has been unsuccessful.
Kerri Kasem and other members of the family held a protest at Kasem's Holmby Hills house to raise public attention to their dispute last month.
The fight is not about an inheritance, Kerri Kasem said.
"My dad told us a long time ago we were not in the will, and we're OK with that. We've known that for years," she said. "I've never asked him for anything, nor have I asked Jean for anything."
Don Pitts, Kasem's agent of more than 35 years, said he did not want to take sides in the argument, but he did say Casey is still of sound mind.
"He has Parkinson's, has it very bad. It took his speech, and for somebody who made millions of dollars using his voice -- for him to lose that gift, that beautiful instrument -- it must be frustrating. But he's handling it very well," Pitts said. "His mind is very sharp, his brain works well. You can tell in his eyes he understands everything you're saying. He just has trouble translating it from the brain to his vocal cords."
Besides the famed countdown shows, Casey Kasem was also the voice of Shaggy in the cartoon "Scooby Doo" and an announcer for NBC. He was a popular DJ and occasional actor before "American Top 40" began in 1970.
