Quick Facts about Dopa-Responsive Dystonia
- Dopa-responsive dystonia (DRD) is a broad term used to
describe forms of dystonia that respond to a medication called levodopa, which
is a synthetic form of a brain chemical called dopamine.
- DRD includes heredity forms that are characterized by
progressive difficulty walking.
- Symptoms of DRD are often worse later in the day and may
increase with exertion.
- DRD can usually be treated effectively with a drug called
levodopa, and most often a combination of levodopa and carbidopa.
- In many cases, full physical functionality—including
walking, running, speaking, writing—is restored or preserved with levodopa
therapy.
