Progressive supranuclear palsy (PSP)

Also called PSP or Steele-Richardson-Olszewski syndrome

Progressive supranuclear palsy (PSP) is a rare condition where nerve cells in parts of the brain are damaged over time. It causes problems with balance, walking, eye movements, speech, swallowing and thinking. It usually starts after age 60 and can be mistaken for Parkinson's disease at first.

What it is

There is no cure, and symptoms get worse over several years.

Physiotherapy, speech and language therapy, occupational therapy and help with eating and swallowing can improve quality of life. Planning ahead for care is important.

Common signs

  • Frequent falls, often backwards
  • Stiffness and slow movement
  • Problems moving the eyes, especially up and down
  • Slurred speech
  • Difficulty swallowing
  • Changes in mood or behaviour

How it is usually diagnosed

  • Examination by a neurologist
  • MRI brain scan
  • Watching how symptoms change over time

Records worth keeping

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

  • Neurology letters
  • MRI reports
  • Therapy plans
  • Swallowing assessments
  • Care plans

Questions to ask your doctor

  • How will the condition change over time?
  • Which therapies could help now?
  • What support is available for carers?

When to get help right away

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

  • Choking, a chest infection with fever and breathlessness, or a serious fall: call 112
