Living with Pontine tegmental cap dysplasia

A non-progressive condition present from birth that affects the hindbrain, causing developmental delay and problems with nerves in the head.

Understanding Pontine tegmental cap dysplasia

Pontine tegmental cap dysplasia (PTCD) is a non-progressive nervous system disorder with a hindbrain malformation and significant developmental delay.

It does not get worse over time. People may have hearing loss, poor balance and coordination (ataxia), speech and language problems, feeding and swallowing difficulty, heart differences and facial paralysis. Severity varies. It is present from birth or infancy.

Signs & symptoms

Symptoms vary from person to person. GARD lists these:

  • Intellectual disability and developmental delay
  • Increased reflexes
  • Hearing loss
  • Poor balance and coordination (ataxia)
  • Speech and language problems
  • Feeding and swallowing difficulty

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.

  3. Ask which tests can help

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