- At 17 – developed sudden psychosis and confusion after GAS infection. Had elevated anti-streptolysin O (ASO) titers. Did not present with typical symptoms of PANDAS – OCD and/or tic-like symptoms were not observed. A tentative diagnosis of PANDAS was given. Treated with antipsychotics, antibiotics, tonsillectomy, and IVIG which resulted in remissions and relapses of his neuropsychiatric symptoms.
- At age 27 – received a trial of therapeutic plasma exchange (TPE), rituximab, and ceftriaxone. Eventually resulted in sustained benefit and minimal fluctuations of his clinical symptoms.
