Living with Parkinsonism-dystonia, infantile

A rare movement condition starting in infancy, with worsening muscle cramps, stiffness, and Parkinson-like symptoms.

Understanding Parkinsonism-dystonia, infantile

Infantile parkinsonism-dystonia (dopamine transporter deficiency syndrome, or DTDS) is a rare movement disorder that usually begins in infancy.

It causes dystonia (long-lasting, uncontrollable muscle contractions and cramps) and parkinsonism, which worsen over time. These make daily activities such as talking, eating, and walking hard. Some people may not have symptoms until childhood or later. Other symptoms can include abnormal eye movements, irritability, sleeping problems, and digestive problems.

Signs & symptoms

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

  • Dystonia (long muscle cramps)
  • Parkinson-like symptoms (parkinsonism)
  • Delays in development
  • Trouble feeding
  • Little or no speech
  • Acid reflux and constipation

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 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

    Parkinson & Movement Disorder Alliance and Dystonia Medical Research Foundation may keep lists of experts for this condition.
