Louis Theroux has made a remarkable transition from satirist of minor celebrities to sympathetic listener to people leading difficult lives. His methods, though, have hardly changed: in sometimes meandering programmes, he ingratiates himself into people’s domestic settings, lets them talk, and then asks pointed questions that sometimes stay just this side of impertinent.

In Louis Theroux: A Different Brain (15 May), Theroux met four people who had suffered major brain injuries. Three of the sufferers were still in various types of sheltered accommodation; the fourth, a woman called Amanda, who had fallen from a horse, had returned home to be with her husband and children again.
