Single dose of mirtazapine modulates whole-brain functional connectivity during emotional narrative processing.

The link between neurotransmitter-level effects of antidepressants and their clinical effect remain poorly understood. A single dose of mirtazapine decreases limbic responses to fearful faces in healthy subjects, but it is unknown whether this effect applies to complex emotional situations and dynamic connectivity between brain regions. Thirty healthy volunteers listened to spoken emotional narratives during functional magnetic resonance imaging (fMRI).

A single dose of mirtazapine attenuates neural responses to self-referential processing.

Increased self-focus is a core factor in the psychopathology of depression. Cortical midline structures (CMS) are implicated in the neurobiology of self, depression and antidepressant treatment response. Mirtazapine, an antidepressant that increases serotonin and norepinephrine release, enhances processing of positive and attenuates processing of negative emotional information in healthy volunteers after a single dose.

[Current Care Guideline: Eating disorders].

Early diagnosis with intervention is linked to better outcome. In primary care patients in risk for eating disorder should be screened and actively asked about eating disorder symptoms. Treatment is mainly out-patient care and should first be focused on gaining a normal nutritional status.

The effect of personality on daily life emotional processes.

Personality features are associated with individual differences in daily emotional life, such as negative and positive affectivity, affect variability and affect reactivity. The existing literature is somewhat mixed and inconclusive about the nature of these associations. The aim of this study was to shed light on what personality features represent in daily life by investigating the effect of the Five Factor traits on different daily emotional processes using an ecologically valid method.

A randomized clinical trial of histamine 2 receptor antagonism in treatment-resistant schizophrenia.

Histamine has important functions as regulator of several other key neurotransmitters. Patients with schizophrenia have lower histamine H1 receptor levels. Since a case report in 1990 of an effect of the H2 antagonist famotidine on negative symptoms in schizophrenia, some open-label trials have been performed, but no randomized controlled trial.
