A woman initially believed to be the victim of an assault on the Gold Coast had actually suffered a seizure, police confirmed on Sunday.

Paramedics, including a critical care response unit, were called to Robina Town Centre Drive in Robina just before 8pm on Friday.

Paramedics initally thought the woman had been bashed but on Sunday afternoon police said she had suffered a seizure and hit her head.

The woman was treated for a head injury and taken to Gold Coast University Hospital in a critical condition.

Police were called to the scene by the Queensland Ambulance Service because paramedics believed she had been assaulted.
