In a sample of 120 long-stay in-patients who fulfilled DSM-III-R criteria for schizophrenia, chronic akathisia and pseudoakathisia were relatively common, with prevalence figures of 24% and 18%, respectively. Compared with patients without evidence of chronic akathisia, those patients with the condition were significantly younger, were receiving significantly higher doses of antipsychotic medication, and were more likely to be receiving a depot antipsychotic. Patients who experienced the characteristic inner restlessness and compulsion to move of akathisia also reported marked symptoms of dysphoria, namely tension, panic, irritability and impatience. The findings support the suggestion that dysphoric mood is an important feature of akathisia. Male patients appeared to be at an increased risk of pseudoakathisia. No significant relation was found between chronic akathisia and tardive dyskinesia, although there was a trend for trunk and limb dyskinesia to be commonest in patients with chronic akathisia while orofacial dyskinesia was most frequently observed in those with pseudoakathisia. Akathisia may mask the movements of tardive dyskinesia in the lower limb. There was no evidence that akathisia was associated with positive or negative symptoms of schizophrenia nor with depression.

1. Two types of psychiatric diagnoses were obtained in a study of the course of early dyskinesia: DSM-III-R and Dimensional Global Ratings of Schizophrenia, Paranoia, Mania and Depression. 2. The strength of association between measures of vulnerability to developing tardive dyskinesia (TD), and clinical components from each of the two methods of obtaining psychiatric diagnoses was established by canonical correlations. 3. Overall, little difference was obtained between DSM-III-R categories and Global Ratings in terms of correlations with TD vulnerability measures. Using components from global diagnostic ratings, the Depression and Schizophrenia Scales made stronger contributions to the canonical functions than Mania and Paranoia. 4. Unipolar depressed patients appear more sensitive to NL: they developed TD after less NL exposure. 5. Dimensional classification appears to be a promising approach to capturing important characteristics of psychoses.

In the context of a prevalence survey of schizophrenia in South Westminster, a questionnaire was administered to 271 patients to assess alcohol-related morbidity. In this epidemiologically based sample, the lifetime prevalence of alcohol abuse was 22.1%. Compared with control patients matched for age and sex, these index cases had a significantly shorter duration of illness. A possible explanation is that drinking may mask the onset of schizophrenia, leading to a delay in diagnosis. The index cases also had significantly higher ratings for hallucinations and for hostility, anxiety and depression, and a greater number of disturbed types of behaviour. The highest levels of alcohol consumption were associated with more severe orofacial dyskinesia, suggesting that alcohol use may be an added risk factor for the development of tardive dyskinesia in some patients. The severity of akathisia was also related to alcohol use, and there were significant relationships between the subjective distress related to akathisia and the level of abuse. A possible interpretation is that alcohol had been used by patients with akathisia to alleviate the associated agitation and dysphoria.

Long-term experience with clozapine has shown that the agent has a motor and mental side effect profile that is distinct in many ways from classical neuroleptics. It can produce a parkinsonian-like bradykinesia and mild akathisia, but no rigidity and rarely tremor. In patients with tardive dyskinesia induced by other neuroleptics, clozapine permits the dyskinesia to disappear in about half the cases. That clozapine may induce tardive dyskinesia in extremely rare cases cannot be excluded, but it seems more likely that this tardive dyskinesia in clozapine-treated patients is due to previous treatment with classical neuroleptics. The earlier clozapine is started, the less chance for development of tardive dyskinesia. As do other neuroleptics, clozapine can elicit sedation and asthenia, but corresponding to the motoric extrapyramidal syndrome, clozapine causes emotional indifference ("mental parkinsonism"), depression, and restlessness to a significantly lesser degree, which may be of importance in the higher compliance seen with this drug.

Abnormalities in saccadic eye movements have been found in schizophrenics with tardive dyskinesia (TD). This finding supports accumulating evidence for a GABAergic dysfunction in the subcortical-cortical circuits controlling motor and oculomotor behavior. We found that in response to muscimol, a direct-acting GABA agonist, changes in the antisaccade error rate and dyskinesia score were strongly correlated. We then looked at the relationship between these measures during single-blind haloperidol withdrawal. Significant changes occurred in antisaccade error during drug withdrawal, but the final measure was not significantly different from the baseline assessment. Antisaccade error change scores were not correlated with dyskinesia change scores. Change score in antisaccade error was positively correlated with change on the Brief Psychiatric Rating Scale, specifically with the Anxiety/Depression factor. These findings suggest that GABAergic mechanisms are more robust than dopaminergic mechanisms in the pathophysiology of persistent tardive dyskinesia.

Ten free monoamines and their metabolites in plasma and cerebrospinal fluid (CSF) were simultaneous measured in 6 levodopa-untreated (LU), 18 levodopa-treated (LT) and 37 levodopa-withdrawn (LW) Chinese patients with Parkinson's disease (PD) and 26 controls. We found that the levels of these substances in LW patients were not significantly different from those in LU patients. In LU- and LW-PD patients, CSF epinephrine (EPI) was higher (P < 0.05) than that of the controls. 3-methoxy-DOPA (3-OMDOPA) might not inhibit the accumulation of 3,4-dihydroxyphenylalanine (DOPA) and dopamine metabolites in CSF. Levodopa treatment might change the dopaminergic and serotoninergic neuronal systems, but not the noradrenergic or adrenergic neuronal systems, in CNS of PD patients. Benserazide (a peripheral decarboxylase inhibitor) in Madopar might decrease the levels of serotonin (5-HT) and norepinephrine (NE), but not those of DOPA and homovanillic acid (HVA), in plasma. HVA, NE and EPI in plasma were not good indices for those in CSF. Otherwise, our results were consistent with some other studies by showing a significantly lower level (P < 0.01) of HVA in CSF of LU- and LW-PD patients than that of the controls, while no difference for NE, 3-methoxy-4-hydroxyphenylglycol (MHPG), 5-hydroxyindole acetic acid (5-HIAA) or 3-OMDOPA was noted. The severity of clinical disability was related to the deficiency of CSF HVA and DOPAC in LU- and LW-PD patients; however, there was no relationship between clinical symptoms of tremor, rigidity-bradykinesia, autonomic dysfunction, dementia, depression or levodopa-induced dyskinesia and CSF monoamines or their metabolites.

To examine the diagnostic significance of precordial ST segment depression in Q wave inferior myocardial infarction, 157 consecutive patients were examined carefully by means of auscultation, ECG, and two-dimensional echocardiography. Precordial ST segment depression was transient (lasting < 72 hours from the onset of myocardial infarction) in 63 patients and persistent (> or = 72 hours) in 40. Twenty-eight patients with persistent, 19 patients with transient, and 14 patients without precordial ST segment depression had advanced asynergy (akinesia or dyskinesia) in the posterior segments, whereas 13 patients with persistent, six with transient, and six without precordial ST segment depression had pericardial rub. Patients with persistent precordial ST segment depression had a significantly higher incidence of severe wall motion abnormality (p < 0.01) and inflammation (p < 0.05) of the posterior wall than the other two groups. In 5 of 40 patients with persistent ST segment depression, pericardial rub was detected in the absence of advanced asynergy in the posterior segments. Although not highly sensitive, persistent precordial ST segment depression appeared to be a fairly specific indicator (specificity 92%) of concomitant posterior involvement with severe wall motion abnormality, inflammation, or both.

Tardive dyskinesia is a side-effect of antipsychotic drugs. Elderly women with depression are at risk even on a low dosis. A case is presented in which a typical depression was treated with high dosis haloperidol resulting in orofacial dyskinesia and a less frequently seen grunting. Correct diagnosis, indication, dosis monitoring and regular evaluation of possible side-effects are the most important factors to prevent these serious invalidating conditions.

The purpose of this study was to determine the prevalence and functional and diagnostic correlates of reported shaking in the community-dwelling elderly. We conducted a standardized neurological evaluation of 1,056 nondemented Medicare recipients in Washington Heights-Inwood, Northern Manhattan (New York). Of 1,056 patients, 108 reported shaking (10.2%). The prevalence of reported shaking did not increase with age. It did differ between ethnic groups, but when adjusted for depression and score on the Schwab and England Activities of Daily Living (ADL) scale, this difference was insignificant. The age-adjusted prevalence was similar for women and men. Neurological examination of the 108 who reported shaking showed that 8.3% had tremor at rest, 17.6% had tremor with action, 5.6% had dyskinesia or chorea, and an additional 28.7% had various problems in coordination or movement. The remaining 39.8% had neither tremor nor problems in coordination or movement. Only 2.9% of individuals with reported shaking had Parkinson's disease (PD), 8.7% had essential tremor, and 2.1% had oral-buccal-lingual dyskinesia. Of the remaining 86.3%, 29 (31%) had no identifiable medical condition. Those who reported shaking were less independent with ADLs, regardless of presence of tremor on examination. Shaking is commonly reported by the community-dwelling elderly. It does not necessarily identify individuals with essential tremor and PD, and is related to decreased independence in ADLs.

Three cases in which patients who were taking fluoxetine for relief of depression showed patterns of abnormal movements suggestive of tardive dyskinesia are presented. In the first case, abnormal facial movements began four weeks after fluoxetine was added to doxepin and lithium and remitted after fluoxetine was discontinued. In the second case, abnormal movements of the mouth and hands were noticed four years after the patient started taking fluoxetine and continued to be present a year after withdrawal of the medication. In the third case, orofacial dyskinesia that had remitted after withdrawal of sertraline and paroxetine and reappeared with fluoxetine was still present eight months after fluoxetine was withdrawn.
