Watch Louis Theroux: A Different Brain 2016

Following on from his recent look at alcoholism, the UK’s premier documentarian returns with another sensitive film, this time on living with a brain injury. Earl’s personality and interests have radically altered since he was involved in a car crash, while Dan – who sustained his injury in the late 90s – is desperate to live independently again. Elsewhere, Amanda is struggling to readjust to family life, and Natalie’s carers share her especially affecting story.
