Hallervorden-Spatz Disease
Definition
Hallervorden-Spatz disease is a movement disorder that is passed down through families (inherited).
Causes
Hallervorden-Spatz usually begins in childhood.
Most cases of Hallervorden-Spatz are due to a defect in a gene that makes a protein called pantothenate kinase 2. Patients with this genetic defect have a buildup of iron in parts of the brain.
Symptoms
Exams and Tests
A nervous system (neurological) examination will show:
- Abnormal postures and movements
- Muscle rigidity
- Tremors
- Weakness
If other family members are affected, this may help confirm the diagnosis.
Genetic tests can look for the defective gene that causes the disease. However, this test is not yet widely available. It is only found at certain research laboratories.
Tests such as MRI can help rule out other movement disorders and diseases.
Treatment
The goal of treatment is to control the symptoms. Although there is no specific treatment for Hallervorden-Spatz disease, taking certain vitamins (including pantothenate, Coenzyme Q10, and other antioxidants) may help.
Outlook (Prognosis)
Hallervorden-Spatz gets worse and damages the nerves over time. It leads to a lack of movement and often death by early adulthood.
Possible Complications
Medication used to treat symptoms can cause complications. Being unable to move from the disease can lead to:
When to Contact a Medical Professional
Call your health care provider if your child develops:
- Increased stiffness in the arms or legs
- Increasing problems at school
- Unusual movements
Prevention
Genetic counseling is appropriate in families affected by this illness. There is no known way to prevent it.
