Filter by:Atypical antipsychotics have been found not only to be beneficial in the treatment of psychotic disorders, but even for depressive symptoms in patients with schizophrenia. Remarkably, preliminary data suggest that the atypical antipsychotic quetiapine has antidepressive properties. Until now, there is limited knowledge concerning the efficacy of quetiapine in major depressive illness and especially in psychotic depression. In our own clinical practice, several patients with psychotic depression were successfully treated with quetiapine as add-on therapy or as monotherapy. On the background of that, the convincing effects of quetiapine in bipolar depression, single-case reports and pilot studies concerning its effectiveness in depressive mood states in psychotic disorders as well as our clinical experiences, it is to assume that a treatment with quetiapine over a 6 weeks period show similar effects in major depressive episode with psychotic features, i.e. psychotic depression. In this pilot study we plan to investigate 20 patients with psychotic features of depression under treatment with quetiapine.
Psychiatric disorders or drug addiction are often regarded as contraindications against the use of Interferon-alpha in patients with chronic hepatitis C. The investigators aim is/was to get prospective data about adherence, efficacy and mental side effects of IFN-alpha treatment in different psychiatric risk groups compared to controls. In a prospective trial, 81 patients with chronic hepatitis C (positive HCV-RNA and elevated ALT) and psychiatric disorders (n=16), methadone substitution (n=21), former drug addiction (n=21) or controls without psychiatric history or addiction (n=23) should be/were treated with a combination of IFN-alpha-2a 3 x 3 Mio U/week and ribavirin (1000-1200 mg/day).
This trial is a 26-week, open label extension trial to investigate safety and explore efficacy of esmertazapine in participants with insomnia who completed protocol 21106/P05701/MK-8265-002 (NCT00631657).
The purpose of this study is to explore the impact of ziprasidone on the distribution of metabolic syndrome risk factors in a population of patients presenting with glucose intolerance, dyslipidemia and/or elevated waist circumference associated with their current antipsychotic medication.
Parkinson's disease (PD) is the second most common neurodegenerative disorder of the elderly that affects a million patients in US. Sleep dysfunction impacts up to 90% of PD patients. PD patients experience a variety of sleep disorders including parasomnias, specifically REM behavior disorder (RBD) that can precede the onset of motor manifestations of PD. RBD has negative consequences on patients' and their bed partners' quality of life mainly due to its impact on the sleep quality and day time alertness. RBD also predisposes affected individuals and their bed partners to physical injuries. There are no FDA approved treatments for RBD. Clonazepam is the most commonly used treatment but carries risks of daytime sedation, tolerance, and withdrawal symptoms. More recently, melatonin has been demonstrated to be effective in several small studies. Ramelteon, a selective melatonin receptor agonist with favorable safety profile, could potentially be effective for the treatment of RBD. This pilot protocol will investigate safety and efficacy of ramelteon for the treatment of RBD in subjects with parkinsonism. We plan to recruit 20 subjects with RBD diagnosed based on the clinical interview and confirmed by the polysomnographic (PSG) data. The study is designed as a prospective randomized placebo controlled 12-week study. Primary outcome measure will be change in frequency of RBD events based on the daily sleep diaries. Secondary outcome measure will be change in the amount of tonic muscle activity based on the results of the baseline and final PSG. A number of other secondary and exploratory outcome measures will be collected
The purpose of this study is to assess the impact of three different treatment modalities on panic symptoms, quality of life and use of health services among individuals consulting an emergency department for non cardiac chest pain and having Panic Disorder.
This study tests the hypothesis that mifepristone will diminish cognitive distortion and alleviate psychosis in patients with schizoaffective disorder.
In the first year of treatment after a FE of SCZ, 75% to 90% of patients achieve remission from psychotic symptoms. However, approximately 40% of FE patients are non-adherent to medication regimes and more than 60% have intermittent periods of gaps of non-adherence. Relapse rates are high with 82% of patients relapsing at least once within 5 years. Unfortunately even amongst those who do achieve full remission from psychotic symptoms, functional recovery remains a major challenge for patients. All the evidence suggests that individuals with SCZ do best with a combination of pharmacology and psychosocial intervention. Cognitive-behavior therapy (CBT) is gaining recognition as an effective treatment in SCZ and is in fact the only psychosocial treatment in SCZ with proven durability at short term follow-up. Although it is currently being used, the investigators need to learn more about the impact of CBT on FE SCZ especially as experts are advocating for CBT to be a critical component of FE clinical services.
Since side effects of antipsychotics, dopamine D2 receptor blockers, frequently occur in older patients with schizophrenia and the risk is dose dependent, clinical guidelines universally advocate the use of lower doses. However, there is no report to test this dosing guideline with measurements of D2 receptor blockade caused by antipsychotics. In this study, dopamine D2 receptor occupancy will be measured, using Positron Emission Tomography (PET), in 40 patients aged 50 and older with schizophrenia-spectrum disorders before and after a gradual 40 % dose reduction of antipsychotics that was safely achieved in the past study while setting a target dose still above the lower limit of the dose range recommended in clinical guidelines for older patients. Our goal is to relate changes in clinical outcome, including subjective and objective clinical ratings, to dopamine D2 receptor occupancy, and compare these results with the data for younger patients in the literature.
Anticholinergic antiparkinsonian agents often cause side-effects including cognitive impairment, dry mouth, and constipation while they diminish antipsychotic-induced parkinsonian symptoms. The introduction of second generation antipsychotics (SGA) brought fewer neurological side effects. However, anticholinergic coprescription rates are still as high as 12-65% in patients on SGA that are much higher than the incidence of EPS reported in clinical trials (3-20%). This apparently discrepancy is likely explained, in part, by the established tradition of routine use of this medications. Older patients are particularly sensitive to anticholinergic side-effects due to age-related changes in pharmacokinetics and pharmacodynamics. In this study, we will examine the safety and benefits of reducing the dose of a frequently prescribed anticholinergics, benztropine, on cognitive function, extrapyramidal symptoms, and psychotic symptoms in older subjects with a primary psychotic disorder.
