According to google: >*Entropic brain theory refers to a hypothesis in neuroscience that suggests that consciousness arises from the brain's ability to balance and maximize information entropy. It posits that the brain operates near a critical point between order and chaos, allowing for the emergence of complex cognitive processes, including consciousness. There are many factors that could contribute to changes in neurological functioning after such medical procedures.* In OP's case, in my opinion, the brain's reboot effect, after waking up, might temporarily improve some neurological functions as the brain regains its equilibrium.. so it's possible that the medically induced coma and subsequent recovery could have caused some alterations in brain activity that temporarily affected his/her stutter. Additionally, being in a medically induced coma could have resulted in: * reduced stress levels * a state of relaxation * a state of self-efficacy as explained [here](https://www.reddit.com/r/Stutter/comments/15fdleq/tips_to_improve_stuttering_from_the_research/)
