Louis Theroux: Extreme Love is scheduled to air at these times (may include spoilers):
Louis visits Phoenix, Arizona, to explore dementia, a condition that steadily erodes the personality of its sufferers and constantly tests the people looking after their loved ones. He visits Beatitudes care home, where he meets Gary, a 69-year-old who thinks he is still a practising dentist and denies ever marrying Carla, his wife of 20 years. He also becomes carer for the day to Nancy, a former New York model who regularly gets confused, but whose husband still sees glimpses of the woman he first fell in love with
