Background: The prevalence of anxiety disorders among children and adolescents are found to be approximately between 8-12 and 5-10, respectively, and the long-lasting effects of such disorders can expose the sufferers to impairment and dysfunction in several areas of life the examples of which are poor educational performance, low self-esteem, and depression. The present study aims to evaluate the efficacy of internet-based, cognitive-behavioral therapy (ICBT) in treating the anxiety disorders among adolescent females...

BACKGROUND: There is insufficient available information on behavioral changes in the absence of cognitive impairment as factors increasing the risk of conversion to dementia. OBJECTIVE: To observe and analyze patients with mild behavioral impairment (MBI), mild cognitive impairment (MCI), and a psychiatry group (PG) to compare the risk of progression to dementia. METHODS: From 677 initially assessed ≥60-year-old patients, a series of 348 patients was studied for a five-year period until censoring or conversion to dementia: 96 with MBI, 87 with MCI, and 165 with general psychiatry disorders, including 4 subgroups: Anxiety, Depression, Psychosis and Others...

Seeking a scientific basis for understanding and treating mental illness, and inspired by the work of Ivan Pavlov, American physiologists, psychiatrists and psychologists in the 1920s turned to nonhuman animals. This paper examines how new constructs such as "experimental neurosis" emerged as tools to enable psychiatric comparison across species. From 1923 to 1962, the Cornell "Behavior Farm" was a leading interdisciplinary research center pioneering novel techniques to experimentally study nonhuman psychopathology...

Rats are widely used animal models for biological psychiatry and neuroscience. Laboratory rats are typically housed in impoverished sensory environments. The lack of species-typical sensory environment might radically change the response of individual animals to stressful and/or threatening episodes. In this report, we demonstrate that behavioral and neural sequelae of chronic stress were modified by sensory environment of adult male rats. This includes effects of stress on the density of spines on CA3 hippocampal neurons, hippocampal neurogenesis and abundance of glucocorticoid or mineralocorticoid receptors...

Human brain imaging can help improve our understanding of mechanisms underlying brain function and how they drive behavior in health and disease. Such knowledge may eventually help us to devise better treatments for psychiatric disorders. However, the brain imaging literature in psychiatry and especially eating disorders has been inconsistent, and studies are often difficult to replicate. The extent or severity of extremes of eating and state of illness, which are often associated with differences in, for instance hormonal status, comorbidity, and medication use, commonly differ between studies and likely add to variation across study results...

OBJECTIVES: School refusal is seen as an emergency in child psychiatry and various risk factors have been analyzed. Children who present with school refusal have been shown to have several associated psychiatric comorbidities. However, risk assessment of psychiatric comorbidities is lacking, particularly in the Indian context. The authors aimed to study the sociodemographic profile and associated psychopathology in children with school refusal. They compared the prevalence rates of psychiatric illnesses to that of the community...

Indian Armed Forces have been engaged in various combat duties for long. The adverse effect of prolonged and repetitive deployment of troops in these highly stressful environment leads to many combat stress behaviors as well as misconduct behaviors. Preventing, identifying and managing these disruptive behaviors are an essential part of combat psychiatry within the larger domain of combat medicine. Indian Armed Forces have a well-oiled mechanism to handle these issues and military psychiatrists are deeply engaged in providing holistic mental health care to the esteemed clientele...

OBJECTIVES: Although second generation long-acting injectable antipsychotics (SG-LAIAs) have been approved and are widely used in adults, there is limited evidence for the use of long-acting formulations in children and adolescents. Thus, we systematically describe the off-label use of SG-LAIAs in clinical practice in adolescent inpatients. METHODS: All individuals admitted to our Children and Adolescent Inpatient Psychiatry Unit receiving treatment with SG-LAIAs between January 2013 and June 2016 were reviewed...

Measuring temporal discounting through the use of intertemporal choice tasks is now the gold standard method for quantifying human choice impulsivity (impatience) in neuroscience, psychology, behavioral economics, public health and computational psychiatry. A recent area of growing interest is individual differences in discounting levels, as these may predispose to (or protect from) mental health disorders, addictive behaviors, and other diseases. At the same time, more and more studies have been dedicated to the quantification of individual attitudes towards risk, which have been measured in many clinical and non-clinical populations using closely related techniques...

Katherine Jonas, Grazyna Kochanska
Although the association between deficits in effortful control and later externalizing behavior is well established, many researchers (Nigg Journal of Child Psychology and Psychiatry, 47(3-4), 395-422, 2006; Steinberg Developmental Review, 28(1), 78-106, 2008) have hypothesized this association is actually the product of the imbalance of dual systems, or two underlying traits: approach and self-regulation. Very little research, however, has deployed a statistically robust strategy to examine that compelling model; further, no research has done so using behavioral measures, particularly in longitudinal studies...

Despite evidence from psychiatry and psychology clinics pointing to altered cognition and decision making following the consumption of cannabis, the effects of cannabis derivatives are still under dispute and the mechanisms of cannabinoid effects on cognition are not known. In this study, we used effort-based and delay-based decision tasks and showed that ACEA, a potent cannabinoid agonist induced apathetic and impulsive patterns of choice in rats in a dose-dependent manner when locally injected into the anterior cingulate cortex (ACC) and orbitofrontal cortex (OFC), respectively...

Learning to make rewarding choices in response to stimuli depends on a slow but steady process, reinforcement learning, and a fast and flexible, but capacity-limited process, working memory. Using both systems in parallel, with their contributions weighted based on performance, should allow us to leverage the best of each system: rapid early learning, supplemented by long-term robust acquisition. However, this assumes that using one process does not interfere with the other. We use computational modeling to investigate the interactions between the two processes in a behavioral experiment and show that working memory interferes with reinforcement learning...

Recent studies demonstrate that personality disorders are prevalent within outpatient psychiatry clinics, though they also are quite common in primary care settings. Studies across multiple health care settings demonstrate that those with a known PD have higher incidences of health problems, higher utilization of the health care system, and have a life expectancy 17.7 years less than that of the population in general. Despite these data, little attention has been directed toward detecting, managing, and treating patients with personality pathology in primary care settings...

Antidepressants (ADs) are among the most frequently used medications in pregnancy. ADs can cross the placental barrier (Rampono et al. Pharmacopsychiatry 2009;42(3):95-100, Loughhead et al. Biol Psychiatry 2006;59(3):287-90), resulting in a dysfunction of the serotonergic and norepinephrine systems, which could cause inattention or hyperactivity-impulsivity behaviors as exhibited in ADHD. Several epidemiological studies have investigated the potential link between AD exposure during pregnancy and the risk of attention deficit disorder with/without hyperactivity (ADHD) in children...

BACKGROUND: In a highly technical civilization like ours, in which the interest in human communication transcends academic barriers and clinical practice, it seems necessary to look back to Ruesch's work in psychiatry. The main reason of it rests upon the idea that he was one of the few truly outstanding clinicians, researchers, and theoretical in the field of normal and abnormal communication. In fact, he did not only present a wealth of observational and clinical data; more importantly, he used these data to formulate creative hypotheses about the conflict between man and other human beings...

BACKGROUND: Lithium is the lightest metal and the only mood stabilizer that has been used for over half a century for the treatment of bipolar disorder (BD). As a small ion, lithium is omnipresent, and consequently, its molecular mechanisms and targets are widespread. Currently, lithium is a crucial pharmacotherapy for the treatment of acute mood episodes, prophylactic therapy, and suicide prevention in BD. Besides, lithium blood level is the most widely used biomarker in clinical psychiatry...

The aim of this study was to test efficacy and safety of intravenous (IV) valproate for aggression in children and adolescents with mood or conduct disorder and concomitant substance abuse. Six patients received a 20 mg/kg dose of IV valproic acid as an add-on therapy to their standard therapy with second-generation antipsychotics and benzodiazepines. Agitation and general psychopathology were measured at baseline and after the first injection using the Modified Overt Aggression Scale, the Brief Psychiatric Rating Scale, and the Children's Global Assessment Scale...

Context: Alcohol dependence is on rise world over, especially in developing countries such as India. According to the World Health Organization, about 30% of Indians consume alcohol, out of which 4%-13% are daily consumers and up to 50% of them, fall under the category of hazardous drinking. Another worrying trend from India is that the average age of initiation of alcohol use has reduced from 28 years during the 1980s to 17 years in 2007. In India, alcohol abuse also amounts to huge annual losses due to alcohol-related problems in workplaces...
