Individual characteristics of treatment responses and therapies provided in the studied GAD-epilepsy patients are shown. X-axis shows the time-points in months starting from symptom onset. The blue line displays seizures / no seizures. Dotted lines refer to the interventions. Orange dots are GAD65 antibody levels. Discontinuation of therapies is shown in parenthesis. 4 wk means 4-week intervals. Patient 1 (A) responded well to early initiation of immunotherapy. With patient 2 (B), there was longer delay before immunotherapy and she continued to experience seizures even after several AED and immunotherapy trials. However, her MRI pathology resolved. Patient 3 (C) responded well to immunoadsorption with decreasing of GAD65 antibody levels after every trial. Patients 4–6 (D–F) did not respond to late immunotherapy. In patient 4, a vagus nerve stimulator ultimately reduced seizure levels. In patient 6, AED modification reduced her seizure levels.
