Olivopontocerebellar Atrophy With Dementia, Blindness, and Chorea

Three Patients With Chorea and Positive Voltage-Gated Potassium Channel Antibody: Is This the Link Between Hyperkinetic von Economo Disease and COVID-19?

“…Unlike dopaminergic agents, there are fewer reports of baclofen as a treatment in chorea. Baclofen, an analog of gamma-aminobutyric acid, is presumed to have helped as the compound is known to be deficient in Huntington’s chorea [ 24 , 25 ]. The last patient who had an abnormal lesion at the right basal ganglia responded symptomatically to olanzapine.…”
