Cigarette smoking may selectively enhance VSWM and attentional deficits in smokers with schizophrenia, which may depend on nAChR stimulation. These findings may have implications for understanding the high rates of smoking in schizophrenia and for developing pharmacotherapies for cognitive deficits and nicotine dependence in schizophrenia.

Background-Schizophrenics smoke at higher rates (58-88%) than the general population (~22%), and have great difficulty with quitting smoking. We determined if the combination of sustainedrelease (SR) bupropion (BUP) with transdermal nicotine patch (TNP) is well-tolerated, and superior to placebo (PLO) + TNP for smoking cessation in schizophrenia.

Background: Second-generation antipsychotics (SGAs) are associated with weight gain, metabolic abnormalities, sedation= sleep disturbance, and prolactin abnormalities, especially in youths. Although stimulants have opposing dopamine receptor and adverse effects, it is unclear whether stimulant co-treatment counteracts the therapeutic or side effects of antipsychotics. Methods: This was a naturalistic cohort study including 153 antipsychotic trials in youths aged 4-19 (mean, 11.3 AE 3.0) years, started on an SGA for clinically significant aggression or oppositionality associated with oppositional defiant disorder, conduct disorder, disruptive behavior disorder not otherwise specified (NOS), impulse control disorder NOS, intermittent explosive disorder, Tourette's disorder, autistic disorder, and pervasive developmental disorder NOS. Patients underwent fasting assessments of body composition, lipids, glucose, insulin, prolactin, sedation, and general efficacy at baseline, weeks 4, 8, and 12, comparing patients co-prescribed stimulants (n ¼ 71) with those not co-prescribed stimulants (n ¼ 82). Results: Patients received risperidone (33.3%), aripiprazole (29.4%), quetiapine (18.4%), olanzapine (11.8%), ziprasidone (5.9%), or clozapine (0.7%). With and without adjustment for differences in baseline variables (sex, prior stimulant use, primary Diagnostic and Statistical Manual of Mental Disorders, 4 th edition [DSM-IV] disorders, co-morbid attentiondeficit=hyperactivity disorder [ADHD], present in 46.3% of youths not receiving stimulants, and some body composition parameters), patients on versus off stimulants did not differ on any of the assessed outcomes (all p values ! 0.1). Conclusions: In contrast to guidelines, stimulant use did not precede or accompany antipsychotic use during the current episode of aggression=oppositionality in almost half of those youths who had aggressive=oppositional behavior and a DSM-IV diagnosis of ADHD. At the clinically prescribed doses, stimulant co-treatment of SGAs did not seem to significantly reduce antipsychotic effects on body composition, metabolic parameters, prolactin, sedation, and broad efficacy.

Even in a relatively well-resourced environment, challenges regarding allocation of appropriate attention to vulnerable populations and integration of treatment response to significant medical and mental health comorbidities remain areas of ongoing programmatic development.

Introduction: Aggression is a common behavioral problem seen in patients with intellectual disabilities (ID). The safety and efficacy of second generation antipsychotics (SGAs), mood stabilizers and antidepressants in the management of aggression in these individuals have minimally been studied. This review aims to 1) summarize the studies conducted using second generation antipsychotics, mood stabilizers and antidepressants in treating aggressive behaviors in patient with ID and 2) determine based on the existing literature, which medications have been examined in the most rigorous study design that might suggest the most efficacy for use in clinical practice. Methods: Literature searches using PUBMED Central, CINAHL Plus, PsychINFO, and Embase databases were conducted using the following terms: intellectual disability/disabilities, mental retardation, developmental disability/disabilities, aggression, agitation, behavior disorder, adult, treatment, management. Studies predominantly including children with ID, and autism/pervasive developmental disabilities spectrum disorders were excluded. Analyses were done by class of medication: SGAs, mood stabilizers and antidepressants. The primary outcome measure was reduction in aggressive or self injurious behaviors as measured by each individual study. Results: The most rigorous study designs found using these agents were randomized controlled trials (RCT). A total of 10 RCTs were found, the majority being with risperidone (3) and lithium (2). Treatment with risperidone showed reduction in aggression when compared to placebo in most RCTs with the exception of one study in which risperidone was not better than placebo. Both lithium studies showed reduction in aggression when compared to placebo. The most abundant literature exists in retrospective chart reviews. The most commonly studied agent was risperidone which showed reduction in aggression in majority of the studies. Conclusions: Limited data exists for treatment of aggression in adults with ID. There are very few studies examining pharmacologic agents using RCTs. Given that risperidone and lithium were the most commonly studied agents in the most rigorous experimental design, it is suggested that these two agents prove efficacious for treatment of aggression in patients with ID. Limitations to most of these studies included concomitant psychotropic administration with variations in types and dosing, severity of ID, and the idea that a wide variety of aggression scales were used to assess outcome. Further research with more scientific rigor is required in this field.
