Comedian David Baddiel has a problem: his 82-year-old dad Colin has a rare form of dementia, which makes him prone to extreme outbursts of swearing, aggression and sexual-inappropriateness. Colin suffers from one of the most extraordinary forms of dementia, called Pick's disease, which has stripped Colin of all his inhibitions, and is stripping him of his memories. Filmed over the course of a year, this extraordinarily intimate Cutting Edge documentary charts David and his brothers' attempts to care for their dad in the aftermath of their mum's death. With the help of his older brother Ivor, David is trying to hold on to what is left of Colin, while at the same time attempting to have a more emotional connection with his dad - the man who he says gave him his sense of humour - before it's too late. By turns deeply moving and funny, The Trouble with Dad is a touching portrait of a family dealing with a situation that many of us may find ourselves in.
