The PARO robot, a 2.7kg soft, fluffy baby harp seal, has showed promising results - calming agitated and distressed patients during a small pilot study last year.

Professor Wendy Moyle from Griffith University says with the number of dementia patients expected to double in the next 20 years, finding new treatments is critical.
