[|AI|]  Hi, Thank you for posting your query. A scale of 7 out of 15 indicates a severe head injury, and only 20% people have good neurological recovery in this condition. As of now (even after two weeks), your friend is unconscious (responding only to painful stimuli). This also indicates a poor chance of good meaningful recovery. For predicting a proper prognosis, investigations such as EEG and evoked potential studies are useful, so is the PET scan of the brain. Best wishes, Chat Doctor.
