City magistrates heard Michael Fowler, 25, knocked Martin Hunter out after punching and kicking him at St Martin's Hospital.
Prosecutor Neil Sweeney said Fowler had become convinced people had labelled him a paedophile and because of his behaviour he was put in a special "calming room" for observation.
He told staff he had calmed down, but laid into Mr Hunter as soon as he opened the door.
"He punched Mr Hunter to the head several times, knocking him to the floor," said Mr Sweeney.
"Fowler then kicked his head and lower body, causing Mr Hunter to lose consciousness. He later said he thought Mr Hunter had been recording him in order to make him out to be a paedophile.
"He now knows that it is not true, but says he was ill at the time."
Mr Sweeney added Mr Hunter was injured in the attack, was forced to take time off work and suffered flashbacks.
Fowler, of Staner Court, Ramsgate, admitted common assault at the Littlebourne Road hospital on October 14 last year.
The court heard he has previous convictions for theft and common assault.
Stuart Green, defending, said Fowler had been suffering mental health problems since 2010.
"There was a time when he was homeless and he also tried to kill himself," said Mr Green.
"What happened that day was that he had asked Mr Hunter to let him out of the room.
"When he did so, my client accepts he punched him and pulled him to the ground, but he does not accept kicking Mr Hunter while he was on the floor. He had become convinced people were calling him a paedophile."
Fowler will be sentenced on June 20.
