What should an international patient prepare before traveling?

Patients should obtain a valid passport and a medical visa (S1 or S2), typically arranged with a letter of invitation from the hospital. Arrange for a certified medical interpreter if the hospital does not provide one, as clear communication is critical. Also, bring all prior medical records, including MRI/CT scans, medication lists, and a referral from your primary neurologist. Plan for a follow-up teleconsultation 3–6 months after return to monitor progress.
