Well, 'Awakenings' is indeed a true story. It recounts actual experiences and situations that took place. The characters and events have roots in reality.
It's hard to say for sure. 'The Awakenings' could be a blend of truth and imagination. Maybe it takes a real concept or incident and builds a fictional story around it.
