Living with Atypical progressive supranuclear palsy syndrome

A rare brain condition that starts late in life and affects movement, speech, and thinking in unusual patterns.

Understanding Atypical progressive supranuclear palsy syndrome

Atypical progressive supranuclear palsy syndrome is a rare disease in which brain cells gradually break down, causing problems with movement, speech, and thinking.

It is a form of progressive supranuclear palsy (PSP) that does not follow the usual PSP pattern. Symptoms begin late in life. There are several types, depending on which problem comes first, such as parkinsonism, gait freezing, speech and language trouble, or eye movement problems.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Slow movements and stiffness (parkinsonism)
  • Eye movement problems, especially looking downward
  • Falls and unsteady walking
  • Freezing of gait
  • Trouble with speech
  • Changes in thinking (dementia)

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include brain and nervous system specialists, eye disease specialists and genetic specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    CurePSP may keep lists of experts for this condition.
