In this article, we present rationales for using complex combination therapy in treatment-refractory bipolar patients and discuss the agents available for use in this therapeutic approach. We review a case example of successful remission that was achievable only with complex combination therapy, and examine its theoretical implications. Practical approaches to devising the optimal complex combination treatment for individual patients are explained, and we look to the development of new methodologies and a more systematic database for decision making in the future.

Although Parkinson's disease is defined by its motor symptoms, the symptoms that are most devastating to patients and caregivers are dementia and psychosis. In addition, sleep has a tremendous impact on patient well being and quality of life. Eighty percent to 90% of Parkinson's disease patients have a sleep disorder affecting their ability to fall asleep, ability to stay asleep, dreams, motor activity during sleep, post-sleep behavior, or day-time somnolence. Treatment plans for patients with Parkinson's disease who experience sleep disorders aim to improve nighttime sleep or daytime wakefulness, and treatment options vary by sleep disorder.

Sleep problems, day somnolence, and fatigue as a result of psychotropic drugs are very common. Psychiatrists usually consider these effects a result of insomnia and treat them by prescribing sleeping pills or other benzodiazepine agents.

We describe here 10 cases of circadian rhythm sleep disorders (CRSD)—and not merely insomnia—as a possible side effect of fluvoxamine (FVA). Two other serotonin reuptake inhibitors, fluoxetine and clomipramine, did not induce CRSD in any of these 10 patients. We speculate that FVA-induced CRSD is caused by the effect of FVA on serotonin and melatonin levels in the central nervous system.

CRSD as a side effect of FVA can be treated by replacing the suspected FVA or adding melatonin to a beneficial FVA treatment. Thus, it is important to be aware of possible iatrogenic CRSD in order to treat appropriately. Prospective studies are needed to confirm our observation and to study the influence of other psychotropic drugs on sleep-wake schedule.

Jealousy is a complex emotion characterized by the perception of a threat of loss of something that the person values, particularly in reference to a relationship with a loved one, which includes affective, cognitive, and behavioral components. Neural systems and cognitive processes underlying jealousy are relatively unclear, and only a few neuroimaging studies have investigated them. The current article discusses recent empirical findings on delusional jealousy, which is the most severe form of this feeling, in neurodegenerative diseases. After reviewing empirical findings on neurological and psychiatric disorders with delusional jealousy, and after considering its high prevalence in patients with Parkinson's disease under dopamine agonist treatment, we propose a core neural network and core cognitive processes at the basis of (delusional) jealousy, characterizing this symptom as possible endophenotype. In any case, empirical investigation of the neural bases of jealousy is just beginning, and further studies are strongly needed to elucidate the biological roots of this complex emotion.

One of the challenges with initiating long-acting injectable (LAI) antipsychotic regimens is achieving relevant drug levels quickly. After first injection of the LAI antipsychotic aripiprazole lauroxil (AL), the lag to reaching relevant plasma aripiprazole levels was initially addressed using supplemental oral aripiprazole for 21 days. A 1-day AL initiation regimen using a NanoCrystal® Dispersion formulation of AL (ALNCD; Aristada Initio®) combined with a single 30 mg dose of oral aripiprazole has been developed as an alternative approach. We compared the 1-day AL initiation regimen (ALNCD + 30 mg oral aripiprazole for 1 day) with the 21-day AL initiation regimen (AL + 15 mg/day of oral aripiprazole for 21 days) using kinetic modeling. Observed and modeled data demonstrate that the 1-day AL initiation regimen provides continuous aripiprazole exposure comparable to the 21-day AL initiation regimen. Each component of the 1-day AL initiation regimen (30 mg oral aripiprazole, ALNCD, and AL) contributes to aripiprazole plasma levels at different times, with oral aripiprazole predominating in the first week, then ALNCD and AL over time. In a double-blind, placebo-controlled, phase 1 study in patients with schizophrenia, the 1-day initiation regimen resulted in rapid achievement of relevant plasma aripiprazole levels comparable to those from the 21-day initiation regimen. Safety and tolerability of the 1-day regimen were consistent with the known profile of aripiprazole. Each part of the 1-day initiation regimen, together with AL, is necessary for continuous aripiprazole exposure from treatment initiation until the next regularly scheduled AL injection is administered.

Distinguishing dependent from recreational drug use can be a surprisingly difficult task, and the current means for identifying substance abuse can be inadequate or even misleading. In subjective self-reports, those who are most at risk may downplay their consumption, not admitting to the full extent of their habit, and measures purely of quantity of use rarely capture the true nature of an individual's relationship to the drug, such as a psychological dependence on the substance. This trend is particularly true for heavy stimulant use, which is absent of the physical withdrawal symptoms that can help identify opiate or alcohol dependence. As such, a simple objective measure to help identify substance abuse, particularly in individuals who might not otherwise raise suspicion, would be a valuable tool in both clinical and experimental settings. We propose that the drug-word Stroop task, an objective assessment of attentional bias and distraction to salient drug-related stimuli, would be a valuable tool in helping to make these categorizations. This measure has been shown to correlate with drug craving, as well as to successfully distinguish dependent from recreational stimulant users and to help to predict outcomes in treatment-seeking individuals. Here, we survey prior literature on the drug-word Stroop task and provide a perspective on using the assessment as a potential diagnostic for drug use severity.

This paper critically examines the literature on face recognition in autism, including a discussion of the neural correlates of this ability. The authors begin by selectively reviewing the behavioral and cognitive neuroscience research on whether faces are represented by a “special” behavioral and neural system—one distinct from object processing. The authors then offer a neuroconstructivist model that attempts to account for the robust finding that certain regions in the inferior temporal cortex are recruited in the service of face recognition. This is followed by a review of the evidence supporting the view that face recognition is atypical in individuals with autism. This face-recognition deficit may indicate a continued risk for the further development of social impairments. The authors conclude by speculating on the role of experience in contributing to this atypical developmental pattern and its implications for normal development of face processing.

Psychopathic individuals account for substantial predatory and impulsive violence. To the present, the principal intervention used to decrease the harm inflicted by psychopaths has been confinement. Nevertheless, most confined psychopathic persons return to the community. Recent advances in the understanding of the neurobiology of psychopathy hold promise for new research directions and more effective treatments. In this article, we will explore recent advances in genetics, electrophysiology, brain imaging, and psychopharmacology, as well as, in brief, their implications for new directions in research and treatment.

This review aims to summarize evidence from published articles regarding the economic burdens on parents of children diagnosed with autism to elaborate on current research status, discern key findings and provide suggestions for future studies. A total of 1024 records were identified through our systematic literature research, and 33 studies were included in the review. The 33 included studies reported findings from 10 different countries around the world. These articles (published from 2003 to 2017) used a variety of research methods, including quantitative (n = 26), qualitative (n = 4), and mixed (n = 3) study designs. In summary, parents of autistic children were susceptible to adverse employment impacts and increased financial burdens, especially mothers. More attention should be given to the development of appropriate medical resource allocation and the alleviation of economic burdens on parents of children with autism.

Serotonin (5-hydroxytryptamine, 5-HT) has long been suspected to play a role in the etiology of depression, and modern neurochemical techniques have confirmed this suspicion. Furthermore, all drugs known to be selective (a relative term) serotonin transporter (SERT) inhibitors are effective antidepressants. Of the selective serotonin reuptake inhibitors (SSRIs) approved in a number of countries for use in depression, panic disorder, and obsessive-compulsive disorder, citalopram is the most selective. Citalopram has been used worldwide to treat an estimated 35 million patients, with an excellent safety record. Citalopram is a racemic drug, and its effects on serotonin transport are thought to reside in the S-enantiomer, known as (S)-citalopram or escitalopram. Escitalopram is the most selective SSRI yet developed. Its receptor binding properties and activity in preclinical animal models of depression predict that escitalopram would be effective in the treatment of depression, with approximately twice the potency of the racemate. The pivotal clinical trials of escitalopram not only support this conclusion, but also suggest escitalopram possesses advantages over citalopram in terms of both efficacy and safety. In conclusion, escitalopram is a promising candidate for use as a first-line antidepressant.

Introduction: A wealth of evidence indicates that neurocognitive deficits are evident in patients with schizophrenia at both illness onset and after many years of treatment. Little is known regarding if or how these deficits change during the lifespan. The goal of the study was to evaluate changes in full-scale intelligence quotient and neurocognitive test performance over a 10-year interval in patients with schizophrenia.

Methods: Twelve patients were administered the Wechsler Adult Intelligence Scale-Revised as a measure of intellectual function and a neuropsycshological test battery including measures of attention, verbal and nonverbal memory, language, visuospatial function, problem-solving, and motor function at entry to the study and at a 10-year follow-up.

Results: With the exception of performance on a measure of speeded motor sequencing, there was no significant decline in any of the measures at 10-year follow-up. Results from a measure of sustained auditory attention showed improvement at follow-up.

Discussion: These data support a neurodevelopmental model of schizophrenia for young adult to middle-age patients by suggesting that neurocognitive deficits that emerge either before disease onset or early in the course of the illness remain stable as the patient ages.

Conclusion: Overall, measures of intelligence quotient as well as specific neurocognitive skills, do not decline over a 10-year period in at least a subgroup of patients with schizophrenia.

Hyperprolactinemia is increasingly prevalent in patients with common psychiatric disorders due to increasing prescriptions of antipsychotics, particularly newer atypical neuroleptics, in these patients. However, measurement of prolactin levels is indicated only in symptomatic patients. When hyperprolactinemia is diagnosed, work-up should include exclusion of other causes of hyperprolactinemia, particularly those that might require treatment. Once such causes have been ruled out, a minority of patients with antipsychotic medication-induced hyperprolactinemia, including those with clinically significant signs and symptoms, will require treatment. When treatment is indicated, specifically when hyperprolactinemia results in amenorrhea in women or testosterone deficiency in men, dopamine agonist therapy is generally not advisable. Hormone-replacement therapy, which involves estrogen/progestogen in women and testosterone in men, can often prevent modification and interruption of successful psychiatric medication regimens.

Recent literature regarding drug-drug, herb-drug, and food-drug interactions must not be ignored; nor can they always be taken at face value. Studies have shown that St. John's wort (SJW) (Hypericum perforatum) can reduce plasma levels of indinavir, cyclosporin, digoxin, and possibly other drugs as well. Current knowledge regarding the metabolism of these medications suggests that the cytochrome P450 (CYP) drug metabolizing enzyme systems cannot account for all these effects. It has been reported that the P-glycoprotein (Pgp) transmembrane pump is also induced by SJW. Medications that are substrates of both CYP 3A4 a Pgp are of particular concern and may pose special interaction risks when combined with certain foods or botanical products such as SJW.

We tested 28 individuals with schizophrenia (SZ) and 16 healthy individuals on a test of logical reasoning and “cognitive gating,” defined as the ability to discriminate between relevant and irrelevant information in confirming or disconfirming a given belief. The Logical Reasoning and Cognitive Gating Task tests both processes under neutral and affect-laden conditions. This is done by presenting formally identical constructs using benign and emotionally arousing language. When separated by symptom profiles, we found statistically significant differences for performance and arousal response between patients with delusions, patients with formal thought disorder, and patients with neither delusions nor formal thought disorder, as well as between patients and healthy controls. When analyzed by error type, we found that nearly all errors by delusional patients were caused by overly restrictive information choice, a pattern that may be related to a delusional patient's tendency to “jump to conclusions” on Bayesian probabilistic tasks. This is in contrast to patients with formal thought disorder, whose low performance resulted also from overly extensive information choice. The tendencies towards restriction were exacerbated by arousal, which is consistent with studies on cognition and arousal in healthy individuals. After briefly examining research on emotional arousal and SZ, and the interaction between emotional arousal and restriction of perceptual cues in healthy individuals, we conclude by suggesting a model which accounts for the distinctive cognitive characteristics of delusional patients by their possessing distinct vulnerabilities to emotional arousal. Specifically, these results suggest the possibility that delusional patients process information in a manner that is essentially intact. However, delusional patients may possess an acute vulnerability to emotional arousal that might cause delusional individuals to behave cognitively as if they were healthy individuals under significantly more severe forms of stress.
