To understand a mechanism of underlying cognitive deficit in schizophrenia, the risk factors, cognitive function, blood dopamine concentrations and glutamate dehydrogenase activities of male schizophrenics with tardive dyskinesia(N=30) were compared with those of schizophrenics without tardive dyskinesia(N=30). The results were as following ; 1) The age, duration of illness and duration of medication were significantly more in schizophrenics with tardive dyskinesia than schizophrenics without tardive dyskinesia(respectively p<0.005, p<0.0001, p<0.0001). 2) The scores of MMSE, TIQ, VIQ and PIQ were significantly lower in schizophrenics with tardive dyskinesia than schizophrenics without tardive dyskinesia (rspectively p<0.0001). 3) Plasma dopamine concentrations were tended to be higher, and serum glutamate dehydrogenase activities were tended to be lower in schiz-ophrenics with tardive dyskinesia than schizophrenics without tardive dyskinesia. 4) The cognitive deficit seemed to be negatively correlated with duration of illness and duration of medication(respectively ${\gamma}$=-0.496, ${\gamma}$=-0.615).

Tardive dyskinesia is a syndrome of involuntary hyperkinetic abnormal movements that occurs during or shortly after the cessation of neuroleptic drug treatment. Typically, the movements are choreoatheoid. Other movements such as tics and dystonia may be present. Nonetheless, any dyskinesia seen in a neuroleptic-treated patient is not always neuroleptic-induced tardive dyskinesia. The prevalence of tardive dyskinesia varies widely, which reflects many methodological problems, such as differential diagnosis. symptom fluctuation, masking effect of neuroleptics, validated diagnostic criteria. Of suggested risk factors, only old age has been consistently found to be associated with an increased frequency of tardive dyskinesia. Many hypotheses about the pathophysiolgy of tardive kinesia are proposeed, but time-honored ones are not present. No consistently safe and effective treatments are found. Various treatment modalities signifies the general ineffectiveness of these agents for most patients. In general, reduction or cessation of neuroleptics, if possible, is recommended. Remission or improvemets of tardive dyskinesia after neuroleptics withdrawal usually occurs among most patients within three months.

Object : This cross-sectional study was performed in order to evaluate the prevalence of tardive dyskinesia among the hospitalized schizophrenic patients. Methods : Four hundred nineteen hospitalized schizophrenic patients(male=263, female=156) were recruited for this study. They were treated with antipsychotics for more than 3 months. The prevalence of tardive dyskinesia was assessed by the Abnormal Involuntary Movement Scale. Results : The prevalence of tardive dyskinesia was 35.6%(Male=36.9%, Female 33.3%). There were no significant differences in the prevalence of tardive dyskinesia among male and female schizophrenic patients. The prevalence of tardive dyskinesia among the patients over 30years old was much higher than those below 30years old. There were no significant correlations between the prevalence of tardive dyskinesia and the duration of hospitalization, the total amount of antipsychotics. The frequently involved parts of the body in the schizophrenic patients who have tardive dyskinesia were tongue, upper extremity, lips and perioral area, jaw, lower extremity, muscles of facial expression trunk, respectively. Conclusions : There was significant correlation between the age and the prevalence of tardive dyskinesia in the antipsychotic-treated schizophrenic patients. There were no correlations between the prevalence of tardive dyskinesia and gender difference, the duration of hospitalization, the total amount of antipsychotics.

Objective : Base on clinical practice, the authors report a case of tardive dyskinesia arising during the course of treatment with resperidal. Methods : This article was review and analysis of a case on risperidone-induced tardive dyskinea. Results : Mrs K, a 51-year-old woman with a 1-year history of schizophrenic disorder, gradually developed tardive dyskinetic movement of the mouth, lip, and tongue over a 4 month period(From July, 1996 to June, 1997) while taking risperidone. Initially she was treated with haloperidol and alprazolam. However, the haloperidol was subsequently discontinued because of EPS developed. From 11th March, 1997, she was observed to have a severe form of tardive dyskinesia involving her tongue, lip, and mouth. After risperidone was withdrawn at 9th May 1997, her tardive dyskinetic movement was disappeared. Conclusions : This is, to our knowledge, the first report of the onset of tardive dyskinesia in a patient taking risperidone. However, additional controlled studies of specific questions are needed ; e.g., the dose-response curves for produce tardive dyskinesia and the mechanism of producing risperidone-induced tardive dyskinea and so on.

Objectives Second-generation antipsychotics (SGAs) are frequently used in the treatment of bipolar disorder. However, there is still no consensus on their risk of tardive movement syndromes especially for first-generation antipsychotics (FGAs)-naïve patients. This study aimed to investigate the prevalence and associated factors of SGAs-related tardive dyskinesia and tardive dystonia in patients with bipolar disorder, in a naturalistic out-patient clinical setting. Methods The authors assessed 78 non-elderly patients with bipolar (n = 71) or schizoaffective disorder (n = 7) who received SGAs with a combined use of mood stabilizers for more than three months without previous exposure to FGAs. Multiple direct assessments were performed and hospital records longer than one recent year describing any observed tardive movement symptoms were also reviewed. Results The prevalence rates of tardive dyskinesia and tardive dystonia were 7.7% and 6.4%, respectively. These patients were being treated with ziprasidone, risperidone, olanzapine, quetiapine, or paliperidone at the time of the onset of the movement symptoms. Tardive dyskinesia was mostly observed in the orolingual area, and tardive dystonia was most frequently detected in oromandibular area. A past history of acute dystonia was significantly associated with presence of both tardive movement syndromes. Conclusions Our findings suggest that SGAs-related tardive movement syndromes occur in a substantial portion of bipolar disorder patients. Acute dystonia, a reported risk factor of tardive movement syndromes in the era of FGAs is confirmed as a risk factor of both tardive dyskinesia and tardive dystonia that were induced-by SGAs.

Tardive dyskinesia(TD), typically appearing as an undesirable side effect of a long term antipsychotic drug treatment has gained increased attention in recent times due to the discovery of many TD variants. This is a single case study of a patient who has undergone more than 8 years of high dosage antipsychotic treatment. After altering the type and dosage of antipsychotic medication 3 months prior to visit, the patient showed relatively abrupt onset symptoms of severe tremor and dystonia. These symptoms, appearing in clear consciousess, got better to a certain degree after 48 hours, worsened for 12 hours, and then improved again. Subsequently there was no continuing movement disorder. Several tests and consultation were carried out. However except for the medication factor, no other possible causes for such disabling symptoms were found. This clinical condition was thought to be akin to tardive tremor, a variant of TD. Furthermore, the course was atypical.

Tardive dyskinesia (TD) is continuous, repetitive movement disorder of tongue, lip or jaw, induced by medication. It causes pain and dysfunction of oral structures but also interferes with dental treatment and overall social life of patients. As a dentist, it is imperative to recognize and manage TD, although currently, there is no definitive treatment for TD. This article reports a patient with TD of tongue, successfully managed with an oral appliance mimicking sensory tricks. Considering the limited treatment options for TD, an oral appliance, a simple and conservative approach, can be a meaningful treatment for some patients with orofacial dyskinesia.

Objective : This study was performed to evaluate the treatment of acupuncture therapy including Herbal Acupuncture in Tardive Dyskinesia. Methods & Result : We treated 1 case of Tardive Dyskinesia patient with Acupuncture and herbal Acupuncture, herbal medicine. Acupuncture therapy was taken on acupoints including CV12 (Chungwan:中脘), ST40 (Pungnyung:豊隆), SP3 (Taeback:太白). As the results of this treatments, little change of tongue motion was observed, but general conditions of the patient was improved. Conclusions : Oriental medical treatments was little effective in this disease, but general conditions of the patient was improved. We think that it need the further study and clinical trial for Tardive Dyskinesia.

Tardive Dyskinesia(TD) may be defined as a syndrome consisting of abnormal, stereotyped involuntary movements, which occurs relatively late in the course of drug treatment and in the etiology of which the drug treatment is a necessary factor like schizophrenia, The frequently involved parts of the body in the schizophrenic patients who have TD were tongue, upper extremity, lips and perioral area, jaws, lower extremity, muscle of facial expression, trunk respectively. The last few years have seen a number of well-conducted clinical, biochemical, neuropathological, and therapeutic studies in patients with TD, but there is no satisfactory treatment for the majority of patients with TD. I used herb medicines and some acupoints like GV20(百會), Extra-point(鎭靜), Extra-point(間谷), Liv20(行間), of the chennel of Gall bladder to treated 2 schizophrenic patients with TD from December 2003 to May 2004. The patients with TD were somewhat improved. Nonetheless for just 2 cases, I might thought that this acupuncture therapy could be helpful to treat schizophrenic patients with TD.However, further studies should be followed.
