Levodopa-carbidopa replacement therapy
Dopamine precursor therapy that addresses the underlying dopamine deficiency in this NR4A2-related movement disorder. Often produces dramatic improvement in both dystonia and parkinsonian features.
Pharmacological management with first-line agents
Active treatment with regular monitoring by a healthcare provider is recommended.
Dopamine agonist augmentation
Adjunctive dopamine agonists may be added when levodopa response is incomplete or to allow lower levodopa doses. Useful for managing residual symptoms.
Additional treatment options
Movement disorder rehabilitation
Specialized physical therapy focusing on gait training, balance, and dystonia management. Includes stretching, strengthening, and functional movement practice.
