Additional Information:
Background: Anti-basal ganglia antibodies (ABGA) are a type of anti-neuronal autoantibody to the basal ganglia in the brain. They are associated with the development of movement disorders such as dystonia and tics [2]. ABGA have been shown to be present in children with psychiatric disturbances following streptococcal infections. These conditions include Sydenham’s chorea and PANDAS syndrome (Paediatric Autoimmune Neuropsychiatric Disorders Associated with Streptococcus infections) [1,2]. They have also been linked to Tourette’s syndrome in adults [3].
