Tardive dyskinesia (TD) is a disfiguring side-effect of antipsychotic medications that is potentially irreversible in affected patients. Newer atypical antipsychotics are felt by many to have a lower risk of TD. As a result, many clinicians may have developed a false sense of security when prescribing these medications. We report five cases of patients taking atypical antipsychotics who develop...

Prolactin response to buspirone was evaluated in patients with schizophrenia, with and without tardive dyskinesia (TD). Prolactin response in patients with schizophrenia without TD was significantly decreased, compared to healthy comparison subjects (F = 6.36, df = 5, p < 0.0001). Furthermore, prolactin levels after administration of buspirone were not significantly increased from baseline. In ...

Purpose: Scapular dyskinesia is a change in position or movement of scapula, which is highly prevalent in athletes with overhead activities. In addition to biomechanical changes in shoulder complex, neurocognitive impairments can have a significant role in its creation. Thus, this study aimed to compare neurocognitive scores between athletes with and without scapular dyskinesia. Methods: I...

Involuntary movement disorders include tremors, tics, myoclonus, athetosis, chorea, dystonia, and dyskinesia. Neuroleptic drugs have the propensity to cause extrapyramidal side effects. Lithium-induced coarse tremors are well documented may occur at therapeutic serum concentrations (0.8-1.0 mEq/L) in treatment of bipolar disorder. Treatment for due lithium includes either dose reduction or non-...

Three hundred and fifty three patients who had been on antipsychotics for three months or more were assessed using Simpson Tardive Dyskinesia Rating Scale. 40.2% of these patients, who merited a diagnosis of probable Tardive Dyskinesia (TD) by the Schooler and Kane criteria, were reassessed three months later and 25.5% of the total sample were found to have persistent TD. Age, total antipsychot...

A decade ago a hypothesis introduced to explain tardive dyskinesia (TD) implicated free radicals generated secondary to neuroleptic treatment. Since then many preclinical and clinical studies have investigated this possibility. These studies suggest that free radicals are probably involved in the pathogenesis of TD and that vitamin E could be efficacious in its treatment.

Compound Formula Rehmannia has been shown to be clinically effective in treating Parkinson's disease and levodopa-induced dyskinesia; however, the mechanisms remain unclear. In this study, we established a model of Parkinson's disease dyskinesia in rats, and treated these animals with Compound Formula Rehmannia. Compound Formula Rehmannia inhibited the increase in mRNA expression of N-methyl-D-...

We studied whether movements associated with tardive dyskinesia (TD) served operant functions in 2 men with developmental disabilities. We found that TD-related movements occurred more frequently in the alone and attention conditions and less frequently in control and demand conditions. Our findings suggest that TD-related movements may not be maintained by social reinforcers and that decreases...

There is a death of literature on the effects of neuroleptics in older schizophrenia patients. In this article, we review the available literature and present findings from our own studies. Neuroleptics are effective in the treatment of late-life schizophrenia, although older patients generally need lower dosages than younger subjects. Neuroleptics, however, carry a relatively high risk of side...

The search for a treatment of tardive dyskinesia (TD) has focused largely on cholinergic and GABAergic agents that are believed to attenuate striatal imbalances and bring about symptomatic control of dyskinetic movements. While numerous reports of the partial effectiveness of acute treatment with cholinergic or GABAergic agents have appeared, the effects of chronic administration of these subst...
