Background: Most studies investigating antipsychotic effectiveness report either total psychopathology or symptom cluster findings. Studies focusing on a separate symptom, such as hallucinations, a hallmark symptom in schizophrenia, are scarce.Therefore, the current study aims to compare the antihallucinatory effectiveness of 3 pharmacologically different antipsychotics: olanzapine, amisulpride, and aripiprazole.

Background: Non-adherence to medication remains a major challenge in the long-term management of patients with schizophrenia. Next to lack of insight into the illness, adverse effects of antipsychotic drugs, cognitive deficits, poor therapeutic alliance, reduced quality of life, missing social support, and negative attitudes toward medication are predictors of non-adherence. This study examined potential correlations between attitudes toward antipsychotic drug therapy, subjective well-being, and symptom change in patients with chronic schizophrenia.

The present naturalistic follow-up investigation aimed to shed a light on this issue by evaluating the time to and the reasons for study dropout in patients suffering from schizophrenia who started monotherapy with an oral new-generation antipsychotic. To this end, psychopathological symptoms and safety data were assessed in 194 patients who were followed up to a maximum observation period of twelve months.

In addition, we investigated whether the reason for the introduction of new antipsychotic medication had an impact on the treatment setting and whether the use of benzodiazepines differed between inpatients and outpatients.
Method: From October 1997 to September 2010, patients with a schizophrenia spectrum disorder according to the International Classification of Diseases, Tenth Revision aged between 18 and 65 years were allocated to a naturalistic drug-monitoring program when starting treatment with a second-generation antipsychotic drug.
Objective: The quality of the patient-psychiatrist relationship can be seen as a cornerstone of adherence to medications in patients with chronic psychiatric disorders. Although therapeutic alliance in psychotherapy has been investigated broadly, it has received little attention in the context of medication adherence. The goal of this study was to develop and validate a user-friendly questionnaire for the assessment of therapeutic alliance in clinically stable outpatients with schizophrenia.

Methods: This study investigated the potential association between changes in psychopathology measured by the Lindenmayer model of the Positive and Negative Syndrome Scale (PANSS) and changes in total plasma bilirubin concentrations. Data of patients with schizophrenia (ICD-10) starting monotherapy with a new-generation antipsychotic were analyzed at baseline (N = 52) and 2 (n = 40), 4 (n = 46), and 12 weeks (n = 30) after the initiation of treatment.

Previous studies on the relationship between plasma levels of new-generation antipsychotics (NGAs) and clinical response did not account for inter- and intra-individual variability in drug levels. Therefore, the present study calculated the ratio of observed versus expected NGA plasma levels and investigated its relationship with changes in the Positive and Negative Syndrome Scale (PANSS). Data of patients starting monotherapy with a NGA were collected 2, 4, 8, and 12 weeks after initiation of treatment.

Background: Nonadherence to medication is still a major problem in the treatment of schizophrenia. The current longitudinal study investigated whether the patients' attitudes toward treatment correlated with the ratio of observed vs expected plasma levels of antipsychotic drugs as an objective measurement of adherence.
Methods: Data of patients starting monotherapy with a new-generation antipsychotic were collected 2, 4, and 12 weeks after the initiation of treatment.
Objective: Patients with schizophrenia often experience sexual dysfunction (SD), to which disorder-related factors like negative symptoms and nondisorder-related factors can theoretically contribute. Thus, we investigated the correlation of SD and serum prolactin level in patients with schizophrenia during antipsychotic treatment.
Methods: We included 39 patients with schizophrenia with a mean age of 34.
Outcome in schizophrenia is multidimensional and consists of clinical and psychosocial domains. Difficulties in affect recognition are a hallmark of schizophrenia, but there is little research investigating the consequences of this deficit on patients' psychosocial status. This cross-sectional study examined the relationship of facial affect recognition and treatment outcomes in terms of psychopathology, quality of life (QOL), and psychosocial functioning.

In the current study 106 outpatients with chronic schizophrenia who had been stable both from a symptomatic and a medication perspective for a period of 6 months before study inclusion were investigated to assess the relationship between a clinical rating of cognitive impairment and the actual performance on neuropsychological tests. The cognitive component of the PANSS was compared to results from a neuropsychological test battery which was selected to cover domains known to be impaired in patients with schizophrenia.

Encoding was associated with frontal, occipital/fusiform, thalamic, and cerebellar activation. CR produced activation in frontal and cerebellar regions, whereas CF activated frontal and occipitotemporal regions as well as the thalamus.

By contrast, correct recognition of previously learned objects (R judgments) produced activation in left superior frontal, bilateral inferior frontal, and right cerebellar regions, whereas correct rejection of distractor objects (N judgments) was associated with activation in bilateral prefrontal and anterior cingulate cortices, in right parietal and cerebellar regions, in the left putamen, and in the right caudate nucleus. The R minus N comparison showed activation in the left lateral prefrontal cortex and in bilateral cingulate cortices and precunei, while the N minus R comparison did not reveal any positive signal change.

It is still being debated whether this is a class effect of second-generation antipsychotics. We conducted a prospective, open study comparing body weight, parameters of insulin resistance in schizophrenia patients treated with either clozapine (n = 10) or amisuLpride ( n = 12).

In this study, we used event-related functional magnetic resonance imaging (fMRI) to investigate gender differences in regional cerebral activity during the perception of positive or negative emotions.
Method: The experiment comprised two emotional conditions (positively/negatively valenced words) during which fMRI data were acquired.

Metabolic side effects have been found earlier during treatment with second-generation antipsychotics. Among those disturbances serum lipids are less investigated. We conducted a prospective, open study in schizophrenia patients in order to compare body weight and serum lipids during treatment with amisulpride, ziprasidone, clozapine or olanzapine over a period of 4 weeks.

Body mass index, serum transaminases, plasma serum levels of the antipsychotic used, and blood cell counts were measured weekly during the first 6 weeks of treatment and monthly thereafter. A considerable proportion of subjects showed an increase beyond normal levels of at least one of the measured transaminases.

Purpose Of Review: The purpose of this paper is to review the recent literature about alterations of lipid and glucose metabolism in patients treated with second generation antipsychotics. This article also addresses possible underlying mechanisms of these changes and discusses ways of preventing these side-effects as well as their management.
Recent Findings: There is a considerable number of reports on this issue but very few prospective controlled trials dealing with this very important subject.
Outcome in schizophrenia is multidimensional and, thus, consists of clinical,humanitarian, rehabilitative and cost domains. Accordingly, recovery is conceptualized as the ability to function in the community, socially and vocationally, as well as being relatively free of disease-related psychopathology. The present cross-sectional study examined the relationship of premorbid functioning, psychopathology, insight, attitudes toward medication and side-effects, as well as sociodemographic factors with treatment outcomes in terms of quality of life (QOL) and psychosocial functioning among 60 regular attendees of a specialized schizophrenia outpatient clinic.

Associations have been found between the severity of cognitive deficits and social dysfunction, impairments in independent living, occupational limitations, and disturbances in quality of life (QOL).
Methods: In this cross-sectional study, the relationships of cognitive deficits and treatment outcomes in terms of QOL, needs, and psychosocial functioning were examined in 60 outpatients with schizophrenia who had a duration of illness over 2 years and had been treated with either clozapine or olanzapine for at least 6 months.
Objective: The present cross-sectional study examined the relationships of psychopathology, side effects, and sociodemographic factors with treatment outcomes in terms of patients' quality of life (QOL), functioning, and needs for care.
Method: Sixty outpatients with chronic schizophrenia who had been treated with either clozapine or olanzapine for at least 6 months were investigated.
Results: Most psychopathological symptoms as well as psychic side effects, weight gain, and female sex were associated with lower QOL, while cognitive symptoms correlated with better QOL.
