Efficacy of risperidone treatment for psychoses associated with schizophrenia, schizoaffective disorder, bipolar disorder, or senile dementia in 11 geriatric patients: a case series.

BACKGROUND: Clinical trials of risperidone, a recently approved novel antipsychotic, included elderly healthy patients, but more data are needed on the effects of risperidone in this population, especially those with comorbid medical illnesses. METHOD: Risperidone was used to treat 11 elderly hospitalized patients between 61 and 79 years of age who manifested signs of psychoses related to schizophrenia, schizoaffective disorder, bipolar disorder, or senile dementia. All patients had been treated previously with classic antipsychotics. Response was assessed by clinical observation of the patients' behavior. RESULTS: Eight patients responded to treatment, 1 did not respond, and 2 had treatment discontinued because of hypotension or dizziness. Positive and negative symptoms decreased markedly in 7 of the responding patients. Four patients had preexisting extrapyramidal symptoms (EPS) and symptoms of tardive dyskinesia that also decreased in response to risperidone treatment. In addition, 4 patients were able to discontinue anti-parkinsonian medications, and 2 were able to discontinue antihypertensive medications. Side effects related to blockade of dopamine, histamine, and serotonin were negligible. No adverse consequences occurred when electroconvulsive therapy, carbamazepine, or lithium was given concurrently. CONCLUSION: The reduction of both positive and negative symptoms of schizophrenia and the lack of significant EPS, tardive dyskinesia, sedation, and anticholinergic side effects indicate that risperidone is a safe and effective medication for the elderly.

The effect of anxiety and depression on completion/withdrawal status in patients admitted to substance abuse detoxification program.

A large proportion of patients entering substance abuse treatment carry psychiatric diagnoses, and some studies have found that those with psychopathology are more likely to withdraw before treatment is completed. We performed a prospective study of patients entering an inpatient substance abuse detoxification program to determine if the degree of anxiety and/or depression correlated with higher dropout rates. On entry to the unit, all patients were administered the Hamilton Rating Scales for Depression and Anxiety. Of the 148 patients studied, 97 (65.5%) completed treatment and 51 (34.5%) withdrew prematurely. There were no significant differences in Hamilton Depression and Anxiety Rating Scale scores between completers and withdrawers. This was true for the total study population, as well as for subgroups of patients based on primary drug abused (heroin or cocaine). Although anxiety and depression are common in substance abusers, we were unable to detect differences on validated anxiety and depression rating scales between those completing and those withdrawing from substance abuse detoxification.

Hyperglycemia and hypertriglyceridemia in real world patients on antipsychotic therapy.

There have been recent reports in the psychiatric literature of the possible association of glucose dysregulation and diabetes mellitus with the use of atypical antipsychotics. This article describes a retrospective chart review of patients from various clinical settings, including a continuing day treatment program, two inpatient programs, and a large private practice. Information was obtained with regard to weight, fasting blood glucose, lipid profiles, EKG changes, and medical comorbidities. The patients included those treated with conventional antipsychotic agents, clozapine, risperidone, olanzapine, and quetiapine. No one antipsychotic agent was associated with a statistically significantly higher prevalence of diabetes, lipid abnormalities, or EKG problems. It was noted, however, that there were higher rates of diabetes (17%), lipid abnormalities (43%), and hypertension (30%) across the sample. This finding suggests that the high prevalence of diabetes, lipid abnormalities, and hypertension in a young, chronically psychiatrically ill population makes the case for aggressive screening.
