Adult-onset tic disorder, motor stereotypies, and behavioural disturbance associated with antibasal ganglia antibodies.

The onset of tics in adulthood is rare and, unlike the childhood variety, there is commonly a secondary environmental cause. We present four cases (1 man, 3 women) with an adult onset tic disorder (mean age of onset, 36 years; range, 27-42 years) associated with the presence of serum antibasal ganglia antibodies (ABGA). One patient had motor tics and unusual motor stereotypies, 2 had multiple motor and vocal tics, and the remaining patient had motor tics only. Concomitant psychiatric disturbance was noted in 3 cases. In 2 cases, there was a close temporal relationship between upper respiratory tract infection and the subsequent onset of tics. Imaging was possible in three cases and was normal in two but revealed a lesion involving the right caudate and lentiform nuclei in the other. We suggest that there might be a causal relationship between ABGA and the clinical syndrome in these cases and that ABGA should be considered as a possible etiology for adult-onset tics.[1]
