Face blindness (prosopagnosia)

Also called Prosopagnosia

Face blindness (prosopagnosia) is when a person has difficulty recognising faces, sometimes even those of close family and friends or their own. Many people are born with it (developmental prosopagnosia) and it can run in families. Others develop it after brain damage, such as from a stroke or head injury.

What it is

It does not affect eyesight, memory or intelligence. Some people do not realise they have it for many years.

There is no specific treatment. People often learn to recognise others by their voice, hair, clothes or the way they walk, and telling others about it can help.

Common signs

  • Not recognising people you know, especially out of context
  • Finding it hard to follow characters in films
  • Relying on voice, hair or clothes to recognise people
  • Avoiding social situations
  • Difficulty recognising your own face

How it is usually diagnosed

  • Questions about how it affects you
  • Face recognition tests
  • Sometimes a brain scan if it started after an injury or illness

Records worth keeping

Keeping these together makes each appointment easier, especially when you see a new doctor:

  • Neurology or neuropsychology letters
  • Test results
  • Scan reports

Questions to ask your doctor

  • Could this be caused by something treatable?
  • Are there strategies that could help me?
  • Is it worth testing my family members?

When to get help right away

Call 112 or go to the nearest emergency department if you have:

  • Sudden face blindness with signs of a stroke, such as face drooping, arm weakness or slurred speech: call 112
