Formula One legend Michael Schumacher is likely “very altered and deteriorated” six years on from suffering serious head injuries after a skiing accident in 2013 and will be a “very different person from who we remember , according to a leading neurosurgeon. Schumacher, 51, has not been seen in public since suffering a traumatic brain injury while skiing off-piste in the French Alps. He was placed in a medically induced coma for six months until June 2014 and has since been treated privately at his home in Switzerland.
