Life when you can't recognise faces

Mary Ann Sieghart and her daughter Evie Prichard both have prosopagnosia, a condition which means they cannot recognise people's faces - even those of friends or family.

In a short film about her experiences for the The One Show, she talked to others with the condition, and a leading expert about the possible causes.

Mary Ann Sieghart also presents Who are you again? on BBC Radio 4 on Friday 1 July at 11:00, or you can listen later via the BBC iPlayer.
