Of 122 Hungarian outpatients treated with neuroleptics, 79 (64.8%) were available for follow-up 7 years after their original assessment for tardive dyskinesia (TD). Ratings on the Abnormal Involuntary Movements Scale and the Simpson Dyskinesia Rating Scale increased significantly. The number of TD cases identified by research diagnostic criteria increased by only 9%: 12 of 28 patients no longer showed TD 7 years later, while 19 of 51 patients developed new TD.
