Hoarders? Extreme collectors? Whichever way you put it, it's a very odd affliction. Learn more about it in this show in which hoarders embark on a six-week treatment programme with psychotherapist Stelios Kiosses and his team, as they receive help to mend their old ways. In the first edition, the experts tackle the habits of 55-year-old Liverpool man Nigel Jennings, who has not been able to enter some of the rooms in his home for more than seven years.
