Overview
Dopamine-responsive dystonia usually starts in childhood, often affecting walking. It responds very well to low doses of levodopa.
Symptoms
- Stiffness or turning in of a foot or leg when walking
- Symptoms that are worse later in the day and better after sleep
- Spreading stiffness to other parts of the body
- Tremor in some cases
Causes and risk factors
It is caused by inherited gene changes that reduce the brain's production of dopamine.
Diagnosis
Diagnosis is based on the symptoms, a good response to a trial of levodopa and genetic testing.
Treatment
Treatment with levodopa usually gives a dramatic and lasting improvement.
When to see a doctor
See a doctor if a child develops walking difficulties that get worse through the day.
