BACKGROUND While most patients with depression respond to combinations of pharmacotherapy, psychotherapy, and electroconvulsive therapy (ECT), there are patients requiring other treatments. Deep brain stimulation (DBS) allows modulation of brain regions that are dysfunctional in depression. Since anhedonia is a feature of depression and there is evidence of(More)
BACKGROUND To assess criteria and to identify predictive factors for functional outcome. The criteria should cover all domains proposed by the Remission in Schizophrenia Working Group. METHOD PANSS ratings were used to evaluate the symptomatic treatment outcome of 262 inpatients with schizophrenia spectrum disorders within a naturalistic multicenter(More)
The goals of this study were to describe demographic variables, drinking history, and the 6-month prevalence of Axis I comorbidity among alcohol-dependent subjects in GERMANY: The variables: amount of alcohol consumption, age at onset of the first alcohol consumed, age at onset of daily alcohol consumption, age at onset of withdrawal symptoms and number of(More)
Depression occurs in approximately 45% of all patients with Parkinson's disease (PD), does not correlate with the stage of motor deficits, reduces quality of life independently of motor symptoms and appears to be underrated and undertreated. Anxiety and depression are the risk factors for the development of PD and may be present many years before the(More)
Depression affects approximately 45% of all patients with Parkinson's disease, reduces quality of live independent of motor symptoms and seems to be underrated and undertreated. Pramipexole shows D(3)- versus D(2)-receptor preference at cortico-frontal dopamine receptors and neurotrophic effects which seem to relate to its antidepressant and anti-anhedonic(More)
OBJECTIVE Second-generation antipsychotics (SGAs) have proven superior to first-generation antipsychotics regarding relapse prevention, mainly in multiple-episode patients. Practice guidelines recommend SGAs as first-line treatment particularly in first-episode patients, although evidence for this group is still limited. Accordingly, the hypothesis of(More)
OBJECTIVE After acute treatment of the first illness episode in schizophrenia, antipsychotic maintenance treatment is recommended for at least 1 year. Evidence for the optimal subsequent treatment is still scarce. Targeted intermittent treatment was found to be less effective than continuous treatment at preventing relapse in multiple episode patients;(More)
Subjectively experienced sleep patterns often differ from observed sleeping behavior in insomniacs. Sleep patterns have been evaluated by measurements of motor activity in healthy subjects and insomniacs, but results may depend on the insomnia subtype. Sleep disturbances are frequent complaints in depression, but the influence of psychopathology on activity(More)
Anhedonia, a core symptom of depression, correlates with motor alterations in major depressive disorder and has been assumed to be frequent in depressed patients with Parkinson's disease (PD). In the present study, the authors assessed for the first time frequency of anhedonia in patients with idiopathic Parkinson's disease (N = 657) and the relationship of(More)
BACKGROUND/AIMS Dibutyltin dichloride (DBTC) is an organotin compound used as a model for acute pancreatitis. The aim was to determine the effect of various doses of Na-selenite on the pathogenesis and course of DBTC-induced toxic changes in organs and serum of rats. METHODS Experimental pancreatitis was induced by intravenous administration of 6 mg(More)
