Living with Early-onset generalized limb-onset dystonia
An inherited dystonia that usually begins in an arm or leg in childhood or the teens and may spread, without affecting intelligence.
Understanding Early-onset generalized limb-onset dystonia
Isolated means it occurs without seizures, loss of intellectual function, or developmental delay. It does not affect intelligence. Symptoms usually start in mid-childhood or the teen years, often with muscle spasms in an arm or leg during a specific action such as writing or walking. In some people it spreads and can occur at rest. It usually does not cause pain. Severity varies, even within a family.
Signs & symptoms
Symptoms vary from person to person. GARD lists these among the most common:
- Muscle spasms in an arm or leg
- Twisting or unusual postures
- Writer's cramp
- Changes in walking
- Tremors
- Voice changes
Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.
Diagnosis
- 1Talk with your doctor
Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.
- 2See a specialist
Specialists who may be involved include brain and nervous system specialists and genetic specialists.
- 3Consider genetic testing
Changes in TOR1A are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
