The effects of haloperidol upon temporal information processing by patients with Tourette's syndrome

Tourettes syndrome patients treated successfully with haloperidol, untreated patients, and healthy controls were studied with tests of temporal discrimination and measures of transmitted information shown previously to be sensitive to brain dysfunction. Untreated patients showed no impairment of temporal processing while those treated with haloperidol showed significant deficit in amount of transmitted information comparable to prior studies of brain syndromes.
