REVIEW
Julio Quezada, Keith A Coffman
Tourette syndrome (TS) is a neurodevelopmental disorder of unknown etiology characterized by spontaneous, involuntary movements and vocalizations called tics. Once thought to be rare, TS affects 0.3-1% of the population. Tics can cause physical discomfort, emotional distress, social difficulties, and can interfere with education and desired activities. The pharmacologic treatment of TS is particularly challenging, as currently the genetics, neurophysiology, and neuropathology of this disorder are still largely unknown...

BACKGROUND: Atypical antipsychotics are associated with metabolic complications that contribute to a higher risk of cardiovascular disease. Current evidence reveal suboptimal adherence to the complex and variable official recommendations on metabolic monitoring in the corresponding patient population. A study evaluating metabolic monitoring at guideline-recommended intervals may help identify areas for intervention. OBJECTIVE: Describe the frequency of monitoring metabolic adverse effects in patients receiving atypical antipsychotics in an outpatient psychiatric clinic with respect to the specific guideline-recommended intervals...

BACKGROUND/AIMS: Serum levels of brain-derived neurotrophic factor (BDNF) and interleukin-6 (IL-6) were prospectively monitored in relation with therapeutic response to lamotrigine augmentation therapy in 46 (15 males and 31 females) inpatients with treatment-resistant depressive disorder during an 8-week treatment with lamotrigine using an open-study design. METHODS: The subjects were 46 depressed patients who had already shown insufficient response to at least 3 psychotropics including antidepressants, mood stabilizers, and atypical antipsychotics...

Using near-infrared spectroscopy, we examined changes in the concentration of oxygenated hemoglobin ([oxy-Hb]) in the frontal lobe during a verbal fluency task in 20 patients with schizophrenia (10 patients each receiving olanzapine [OLZ] and risperidone [RIS]) and 10 healthy controls. We found that [oxy-Hb] levels in the prefrontal region were higher in the patients receiving OLZ than in those receiving RIS. These results suggest that antipsychotic drugs have different effects on cerebral hemodynamic patterns, which may reflect frontal lobe function...

The current research evaluated metabolic side effects in inpatients (N = 271) using atypical antipsychotic medications in a psychiatric hospital in Turkey between June and December 2016. Data were collected via an information form created after reviewing the literature at the time of patients' hospitalization and discharge. According to the analysis, 73.8% of patients stated they experienced side effects from antipsychotic medications and 20.7% of patients experienced weight gain. A statistical difference was detected among body mass index, waist circumference, diastolic blood pressure, and heart rate during patient hospitalization and discharge...

Atypical antipsychotics increase the risk of diabetes and cardiovascular disease through their side effects of insulin resistance and weight gain. The populations for which atypical antipsychotics are used carry a baseline risk of metabolic dysregulation prior to medication which has made it difficult to fully understand whether atypical antipsychotics cause insulin resistance and weight gain directly. The purpose of this work was to conduct a systematic review and meta-analysis of atypical antipsychotic trials in healthy volunteers to better understand their effects on insulin sensitivity and weight gain...

The pharmaceutical industry is facing enormous challenges due to high drug attribution rates. For the past decades, novel methods have been developed for safety and efficacy testing, as well as for improving early development stages. In vitro screening methods for drug-receptor binding are considered to be good alternatives for decreasing costs in the identification of drug candidates. However, these methods require lengthy and troublesome labeling steps. Biosensors hold great promise due to the fact that label-free detection schemes can be designed in an easy and low-cost manner...

Silki, Vivek Ranjan Sinha
Aripiprazole (ARP), a second-generation or atypical antipsychotic, is poorly soluble and undergoes extensive hepatic metabolism and P-glycoprotein efflux which lead to reduced in vivo efficacy and increased dose-related side effects. To enhance in vivo efficacy and oral bioavailability of aripiprazole, aripiprazole-loaded solid lipid nanoparticles (SLNs) were developed using tristearin as solid lipid. Tween 80 and sodium taurocholate were used as surfactants to prepare SLNs using microemulsification method...

Psychosis is reported over 30% of patients with Alzheimer's disease (AD) in clinics. Aripiprazole is an atypical antipsychotic drug with partial agonist activity at the D2 dopamine and 5-HT1A receptors with low side-effect profile. We identified aripiprazole is able to overcome the amyloid-β (Aβ)-evoked neurotoxicity and then increase the cell viability. This study elucidated the mechanism(s) by which aripiprazole ameliorates Aβ1-42-induced decreased neurite outgrowth and viability in neuronal cells. Pretreatment with aripiprazole increased Brain-derived neurotrophic factor (BDNF) mRNA and protein expressions in N2a cells...

Symptomatic characteristics and recent advances in understanding the pathophysiology of tardive dyskinesias and levodopa-induced dyskinesias were reviewed. After the advent of atypical antipsychotics, tardive dyskinesias became less frequent, at least as observed during a short-term follow up. The dopamine supersensitivity hypothesis stating that blockade of dopamine D2 receptors by antipsychotics makes D2 receptors more sensitive to dopamine, has long been proposed. However, the true mechanisms remain to be determined...

Sleep abnormalities have recently gained renewed attention in patients diagnosed with Schizophrenia. Disrupted thalamocortical brain oscillations hold promise as putative biomarkers or endophenotypes of the disorder. Despite an increase of studies related to sleep spindle and slow wave activity, findings remain in part contradictory. Although sleep spindle deficits have been confirmed in several groups of patients with chronic, medicated Schizophrenia, data on the early stages of the disorder and in unmedicated subjects are still insufficient...

Oscillatory activity in the gamma frequency range is a critical mechanism, which integrates neural networks within and across brain structures during cognitive processes. In schizophrenia, abnormalities in high gamma oscillations are ubiquitous and most likely reflect dysfunction in neuronal networks. In conscious rats, disturbed network oscillations associated with positive symptoms and cognitive deficits were modeled in different cortical areas by the dopaminergic agonist (amphetamine) and the N-methyl-D-aspartate (NMDA) receptor antagonists (PCP and MK801)...

BACKGROUND: Hospitalization accounts for significant health care resource utilization for treatment-resistant Bipolar Disorder (BD), especially among frequent users of acute inpatient psychiatric units. Appraisal of the clinical features and predictive role of selected variables is therefore crucial in such population, representing the aim of the present research. METHODS: A hundred and nineteen BD inpatients with an established history of pharmacological treatment resistance for either mania or bipolar depression were classified as long hospitalization cases (LOS+) and their controls and compared against each other for a number of demographic, clinical, and psychopathological features...

Aripiprazole (ARP) is a partial agonist of dopamine D2 receptors that is commonly prescribed to treat schizophrenia and bipolar disorder. The anti-inflammatory effect of ARP was recently documented in a few studies, but its molecular mechanisms have not been fully elucidated. In this study, peptidoglycan (PGN)-treated macrophages (RAW264.7 cells), reporter gene assay, an overexpression strategy, immunoprecipitation, and immunoblotting analysis were employed to clarify the anti-inflammatory mechanism of ARP...

Depression is a nosological entity which may appear alone or concomitantly (e.g. in schizophrenia). Analysis of data from both clinical and experimental studies allows a conclusion that atypical antipsychotics, such as aripiprazole (ARI), may also be effective in treating depression in addition to antidepressants. The aim of the studies was to determine antidepressant efficacy of ARI, venlafaxine (VEN) and combined therapy using both drugs, in prenatally stressed rats (animal depression model) and control group...
