Hallervorden-Spatz disease
Definition
Hallervorden-Spatz disease is a movement disorder that is passed down through families (inherited).
Alternative Names
Pantothenate kinase-associated neurodegeneration
Causes
Hallervorden-Spatz disease usually begins in childhood.
Most cases of Hallervorden-Spatz disease 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
- Dementia
- Involuntary muscle contractions (dystonia)
- Movement problems
- Muscle rigidity
- Seizures
- Spasticity
- Tremor
- Vision changes
- Weakness
- Writhing movements
Exams and Tests
The doctor or nurse will examine you and ask questions about your symptoms and medical history. The exam may show:
- Abnormal postures and movements
- Muscle rigidity
- Tremors
- Weakness
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
There is no specific treatment for Hallervorden-Spatz disease. Treatment is focused on controlling the symptoms.
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:
- Blood clots
- Respiratory infections
- Skin breakdown
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.
