RecruitingClinical trialManaging Transient Neurologic Episodes in Surgery for Moyamoya DiseaseThe goal of this study is to study the incidence of post-operative Transient Neurologic Events (TNEs) within 30 days postoperatively, as assessed by clinical neurological scales, binned by week. Collect data on all interventions and assessments performed during the recovery post surgery up to 30 days, to understand what factors might cause Transient Neurologic Events (TNEs) and determine how these can be reduced in Moyamoya subjects post surgery.
