This study assessed the association between second-generation antipsychotic medications and risk of pneumonia requiring hospitalization in patients with schizophrenia because the evidence is limited in the population. We enrolled a nationwide cohort of 33,024 inpatients with schizophrenia ranged in age from 18 to 65 years, who were derived from the National Health Insurance Research Database in...

Increased responding to drug-associated stimuli (cue reactivity) and an inability to tolerate delayed gratification (reward impulsivity) have been implicated in the development and maintenance of drug addiction. Whereas data from animal studies suggest that both the dopamine and opioid system are involved in these two reward-related processes, their role in humans is less clear. Moreover, dopam...

Perceptions are inherently probabilistic; and can be potentially manipulated to induce illusory experience by the presentation of ambiguous or improbable evidence under selective (spatio-temporal) constraints. Accordingly, perception of the McGurk effect, by which individuals misperceive specific incongruent visual and auditory vocal cues, rests upon effective probabilistic inference. Here, we ...

(1) Background: The concentration of amisulpride, an atypical antipsychotic drug, is most often determined in the blood, with many inconveniences. An alternative may be to use saliva as a diagnostic material for this purpose. development method determine amisulpride using small volume biological could significantly improve patient comfort during Therapeutic Drug Monitoring (TDM). (2) Methods: T...

Conventional antipsychotic medication is commonly prescribed to patients with autistic spectrum disorder. However, a high incidence of severe adverse reactions highlights the need to find more favourable treatments. Atypical antipsychotics may combine efficacy in ameliorating some autistic symptoms with a lower incidence of some adverse reactions. This article reviews the use of atypical antips...

We report about a clinical observation in a well-characterized group of patients with obsessive-compulsive disorder (OCD) during an experimental medicine study in which a single dose of amisulpride (a selective D₂/₃ antagonist) was administered. Almost half of the OCD patients, in particular those with less severe obsessive-compulsive symptoms, experienced acute akathisia in response to the ami...

One-third to half of patients taking clozapine suffer from refractory symptoms despite adequate treatment. Among other adverse effects, clozapine-induced hypersalivation (CIH) occurs in approximately half of all patients. This is a case of a 30-year-old male with refractory schizophrenia; in this patient, the remission of residual positive symptoms, as well as the reduction of CIH, was achieved...
