1/94. risperidone-induced rabbit syndrome: an unusual movement disorder caused by an atypical antipsychotic.Rabbit syndrome is a rare side effect of chronic neuroleptic administration characterized by rapid, fine, rhythmic movements of the mouth along a vertical axis. It gains its name from an unusual resemblance to the chewing and puckering motions of the rabbit. It is generally thought to be an extra-pyramidal side effect, in part due to its rapid response to anti-cholinergic medication. This is the first case report of risperidone, an atypical antipsychotic, inducing the syndrome. The theoretical implications for the classification of the syndrome along the spectrum of neuroleptic-induced movement disorders are discussed.- - - - - - - - - - ranking = 1keywords = psychotic (Clic here for more details about this article) |
2/94. diazepam in the treatment of tardive dyskinesia. Preliminary observations.Three patients, aged 23-33 years, with the diagnosis of schizophrenia, developed symptoms of tardive dyskinesia while receiving neuroleptic treatment, mostly with haloperidol. Existential problems and emotional upset seemed contributory. diazepam was found effective in controlling dyskinesia. Its therapeutic effect seemed not to be related to sedation. Some implications of the reported observations are mentioned.- - - - - - - - - - ranking = 0.62140210632697keywords = schizophrenia (Clic here for more details about this article) |
3/94. Antipsychotic-induced life-threatening 'esophageal dyskinesia'.We report two patients with lingual dyskinesia and complaints of food regurgitation following long-term antipsychotic therapy. Esophageal contrast radiography revealed dyskinetic movements extending from the pharynx to the upper portion of the esophagus. The elevation of intraesophageal pressure was confirmed by esophageal manometry. The dyskinetic movements almost disappeared along with improvement of lingual dyskinesia following the administration of sulpiride in one patient. Another patient suddenly died due to asphyxiation of foods before the beginning of treatment. We termed this life-threatening movement, 'esophageal dyskinesia'. It should be emphasized that 'esophageal dyskinesia' associated with lingual dyskinesia is a potentially fatal adverse reaction to antipsychotic therapy.- - - - - - - - - - ranking = 1.2keywords = psychotic (Clic here for more details about this article) |
4/94. Gabapentin as a promising treatment for antipsychotic-induced movement disorders in schizoaffective and bipolar patients.Improvement of antipsychotic-induced blepharospasm and involuntary oral-mandibulo movements was observed with the use of the anticonvulsant drug gabapentin among 14 of 16 affectively ill patients who had been exposed to maintenance neuroleptics of the conventional type. In many cases, the movement disorders of these patients had not responded to more standard measures such as clozapine. This finding permits a potential strategy for patients with treatment-emergent tardive dyskinesia, a well-known complication of extended conventional neuroleptic use. Gabapentin, whose mood stabilizing properties have been reported in several clinical reports, represents a more natural treatment in the setting of bipolar spectrum disorders.- - - - - - - - - - ranking = 1keywords = psychotic (Clic here for more details about this article) |
5/94. Two cases of risperidone-induced tardive dyskinesia and a review of the literature.Acase in which a 26 year old patient with undifferentiated schizophrenia, showing abnormal oral, lingual and jaw movements suggestive of tardive dyskinesia during a dose reduction of risperidone, is presented. A second case, relating to a 39 year old married woman diagnosed as having a DSM-IV schizophreniform disorder is also presented. These two cases are discussed in relation to the existing literature.- - - - - - - - - - ranking = 0.62140210632697keywords = schizophrenia (Clic here for more details about this article) |

Rapid resolution of antipsychotic-induced tardive dyskinesia with olanzapine.Rapid improvement of tardive dyskinesia was identified following initiation of olanzapine in an elderly male patient formally treated with chlorpromazine.- - - - - - - - - - ranking = 0.8keywords = psychotic (Clic here for more details about this article) |
7/94. risperidone implicated in the onset of tardive dyskinesia in a young woman.The aim of this case report is to highlight that risperidone may cause and ameliorate tardive dyskinesia. A 16 year old white women with a 12 month history of schizophrenia, developed buccolingual masticatory tardive dyskinesia after receiving risperidone 6 mg. She had received small dosages of typical antipsychotics before and during receiving risperidone for short periods. Recommencement of risperidone with 2 mg and increasing to 6 mg resulted in improvement in tardive dyskinesia and up until now she remains free of any abnormal involuntary movements.- - - - - - - - - - ranking = 0.82140210632697keywords = schizophrenia, psychotic (Clic here for more details about this article) |
8/94. Remission of severe tardive dyskinesia in a schizophrenic patient treated with the atypical antipsychotic substance quetiapine.In a single inpatient case study, a schizophrenic patient with tardive dyskinesia after prolonged treatment with typical neuroleptics was treated with the new atypical neuroleptic quetiapine, a dibenzothiazepin-derivative. Within 2 weeks of treatment with quetiapine, symptoms of tardive dyskinesia improved; 10 weeks after starting treatment tardive dyskinesia stopped completely. Over the same period, dopamine D2 receptor occupancy decreased substantially, as measured by IBZM-SPECT after 14 and 77 days of treatment.- - - - - - - - - - ranking = 0.8keywords = psychotic (Clic here for more details about this article) |
9/94. Tardive dystonia provoked by concomitantly administered risperidone.Two cases of tardive dystonia are reported. The first case was an 18-year-old schizophrenic woman suffering from parkinsonism and hypotension induced by antipsychotic drugs. risperidone (4 mg/day) was added to her drug regimen and after increasing the dosage to 6 mg/day, she began to exhibit retrocollis. The second case was a 61-year-old woman who had schizophrenia and tardive dyskinesia. After replacing chlorpromazine (75 mg/day) with risperidone (4 mg/day), she began to exhibit retrocollis. The retrocollis in both cases was considered to be tardive dystonia provoked by risperidone administered concomitantly with other antipsychotics. risperidone is reported to produce few extrapyramidal symptoms, but these cases suggested that changing from other drugs to risperidone, or rapidly increasing risperidone dosage, may provoke tardive syndrome.- - - - - - - - - - ranking = 1.021402106327keywords = schizophrenia, psychotic (Clic here for more details about this article) |
10/94. Improvement of tardive dyskinesia with risperidone: a case report.This case report illustrates the improvement of tardive dyskinesia (TD) and psychotic symptoms in an elderly Thai female with chronic schizophrenia with a long history of conventional antipsychotic exposure following the treatment with risperidone 2 mg/day. TD disappeared in 9 months and continued to be in remission at her 5-month follow-up visit recently.- - - - - - - - - - ranking = 1.021402106327keywords = schizophrenia, psychotic (Clic here for more details about this article) |
