The authors describe 80 patients with neurosurgical disorders treated with tiapride, either during neurosurgical investigations including radiological examinations after removal of cerebrospinal fluid, or for agitation following alcoholism or meningeal haemorrhage. The authors stress the value of tiapride for patients undergoing radiculography and especially gas myelography procedures. The effect of tiapride on the various manifestations of agitation was also spectacular and rapid, and the authors confirm the excellent tolerance of the product.
