An Asiatic bear in Laos became the first of its kind to undergo a brain surgery.

The vets and staff and Free the Bears sanctuary were troubled by the erratic behavior shown by Champa and suspected that she was suffering from hydrocephalus, a condition similar to having a 'constant migraine'.
Pizzi, who works at Edinburgh Zoo in Scotland, carried out the six-hour long surgery in February. Speaking to National geographic, the chief executive of Free the Bears, Matt Hunt said that Champa’s condition has improved following the surgery. “There was a lot more recognition. We can't know if her vision is fully recovered, but everyone certainly believes her vision has improved”, he said.
