Casey Kasem, host of the "American Top 40" countdown for four decades, remained in critical condition at a Washington state hospital on Sunday and was being treated for an infected bedsore, a hospital spokesman said.
Kasem, who was also the voice of Shaggy in the "Scooby-Doo" cartoons and one of the most recognisable voices on American radio, was admitted to St Anthony Hospital in Gig Harbor last week.
The 82-year-old former DJ has been alert throughout his hospitalisation, receiving wound care, intravenous antibiotic therapy, blood pressure support medication and treatment for his pain, hospital spokesman Scott Thompson said.
Kasem suffers from Lewy body disease, a form of dementia with symptoms similar to Parkinson's disease and hallucinations.
His medical care and visitor access has been at the centre of a legal tussle between the children from his first marriage - Kerri, Julie and Mike - and his second wife, Jean Kasem, with whom he has one child, Liberty.
A Washington state judge ruled on Friday that Kasem's care would be decided by his daughter, Kerri, and not her stepmother.
As the ruling took effect, a family spokesman said Kasem "won't be with us much longer".
