**8. Treatment**

There is no ideal treatment option present targeting the basic pathogenic mechanisms of Graves' disease. Available treatment options target the increased synthesis of thyroid hormones by antithyroid drugs, or ablation of thyroid tissue by surgery or radioiodine. Antithyroid drugs are the predominant therapy in Europe and Japan whereas radioiodine is first line of treatment in USA. No single treatment is optimal and patients often require multiple treatment.
