Continuous Intrajejunal Levodopa–Carbidopa Infusion in Parkinson's Disease Associated with 22q11.2 Deletion Syndrome: A Case Series

Movement Disorders Clinical Practice, EarlyView.
Abstract Background 22q11.2 deletion syndrome (22q11DS) is a multisystem genetic disorder associated with a significantly increased risk of early‐onset Parkinson's disease (EOPD). Management is challenging because psychiatric and cognitive comorbidities often limit advanced therapies such as deep brain stimulation (DBS). Cases We report 2 patients with
