1. An ambulatory activity monitor with solid-state memory was employed to obtain 24-hour activity data in 29 neuroleptic-treated hospitalized patients and 9 normal controls. 2. The activity monitor is a piezoelectric device which was strapped to the non-dominant ankle. Activity was recorded in 5-minute epochs throughout the 24-hour period. 3. In contrast to(More)
A rating scale for tardive dyskinesia was developed, consisting of nearly all signs seen by two groups of investigators over a 5-year period. Thirty-four items were included in the scale with a possibility of writing in idiosyncratic signs. The scale was shown to have good reliability and validity in studies carried out by both the New York and Boston(More)
A 5-year follow-up investigation of TD was carried out in 85 Hungarian schizophrenic out-patients. No substantial changes occurred during the 5 years in pharmacotherapy: most patients continued on neuroleptics and antiparkinson drugs. Comparison of 1978 and 1983 ratings revealed increased dyskinesia scores, which was statistically significant on the DRS(More)
OBJECTIVE The purpose of this study was to assess the long-term outcome of patients with tardive dyskinesia. METHOD A group of 122 neuroleptic-treated Hungarian outpatients were assessed for tardive dyskinesia on the Abnormal Involuntary Movement Scale and the Tardive Dyskinesia Rating Scale by the same rater over a 10-year period. RESULTS Sixty-three(More)
Tardive dyskinesia, tardive akathisia, and tardive dystonia are reviewed from a clinical perspective. The evaluation of each syndrome is discussed, and its clinical presentation and course are illustrated with case vignettes. Drugs used in the treatment of tardive dyskinesia are presented, with greater emphasis on the more recently introduced therapies such(More)
The authors conducted a double-blind, controlled study to test the behavioral, affective, and neurological effects of antiparkinson drug discontinuation. Patients were evaluated at baseline and at 2 and 4 weeks. Of 24 placebo patients 9 left the study early because of adverse effects; none of the 8 patients in the antiparkinsonian group did so. The placebo(More)
The serious long-term complications of maintenance antipsychotic therapy led the authors to undertake a critical review of outpatient withdrawal studies. Key findings included the following: 1) for a least 40% of outpatient schizophrenics, drugs seem to be essential for survival in the community; 2) the majority of patients who relapse after drug withdrawal(More)
Benztropine mesylate (intravenous [IV] and oral) challenge was compared with brief neuroleptic withdrawal on dyskinesia ratings and symptom measures. Thirty-six neuroleptic-treated patients underwent a placebo-controlled acute IV challenge with 2 mg benztropine and a placebo-controlled two-week trial of oral benztropine mesylate (2 mg three times a day),(More)
Jurkat lymphoblasts were stimulated by a monoclonal antibody against the CD3 membrane antigen and the evoked calcium signal was followed by the intracellular fluorescent calcium indicator indo-1. The technique applied allowed us to separately investigate the stimulus-induced intracellular calcium release and the calcium-influx pathways, respectively. In the(More)
