About 100,000 people in the UK have facial palsy, where half the face is paralysed causing an inability to fully smile, blink one eye or raise one eyebrow.
A charity is being launched to support sufferers and raise awareness.
Consultant Ahmed Sadiq, who specialises in helping people with facial palsy, explains the condition in more detail, and Amanda Taylor describes how the condition has affected her everyday life.
