Molly Meldrum’s short term memory loss means he can forget where he is and his brother says it’s impossible to predict the extent of his final recovery.

The music industry icon was transferred to a private rehabilitation facility on Thursday after five weeks in The Alfred hospital in Melbourne.

His brother Brian Meldrum told the Seven Network the celebrity interviewer is often in high spirits, but at times can’t remember where he is.

Meldrum is suffering from post-traumatic amnesia, with symptoms that include short-term memory loss and disorientation.
