BACKGROUND: Low-field magnetic stimulation (LFMS) has mood-elevating effect, and the increase of brain-derived neurotrophic factor (BDNF) is associated with antidepressant treatment. We evaluated the effects and association with BDNF of rhythmic LFMS in the treatment of major depressive disorder (MDD). METHODS: A total of 22 MDD patients were randomized to rhythmic alpha stimulation (RAS) or rhythmic delta stimulation (RDS), with 5 sessions per week, lasting for 6 weeks...

Psychiatric evaluations of violent political crime were mostly performed on a case-by-case basis in a forensic environment, which made them unduly dependent on categories of presumed dangerousness and legal responsibility, rather than on a clinical definition of their mental status. In referring to such "clinical" definitions, the disorder we have in mind is not limited to the major, agitated psychotic manias or mixed states. The presence of a dominant temperament, or protracted hypomania, is enough by itself to explain an individual's engagement in a wide range of activities, not necessarily sociopathic or violent...

Introduction Oxidative stress has been documented in chronic schizophrenia and in the first episode of psychosis, but there are very little data on oxidative stress prior to the disease onset. OBJECTIVE: This work aimed to compare serum levels of superoxide dismutase (SOD) and glutathione peroxidase (GPx) in young individuals at ultra-high risk (UHR) of developing psychosis with a comparison healthy control group (HC). METHODS: Thirteen UHR subjects and 29 age- and sex-matched healthy controls (HC) were enrolled in this study...

Functional neurological disorders (FND)-also called psychogenic, nonorganic, conversion, and dissociative disorders-constitute one of the commonest problems in neurological practice. An occupational therapist (OT) is commonly involved in management, but there is no specific literature or guidance for these professionals. Classification now emphasizes the importance of positive diagnosis of FND based on physical signs, more than psychological features. Studies of mechanism have produced new clinical and neurobiological ways of thinking about these disorders...

There is a great unmet need for new medications with novel mechanisms of action that can effectively treat patients who do not benefit from standard antidepressant therapies. After a period in which it seemed as if the pharmaceutical pipeline for new antidepressants was going dry, the past decade has witnessed renewed interest, beginning with discovery of the antidepressant effects of ketamine. This article briefly highlights more recent research on ketamine and other investigational antidepressants.

Mood disorders including major depressive disorder and bipolar disorder are common during and after pregnancy. Timely identification and appropriate management of mood episodes is essential to maximize maternal well-being and minimize adverse outcomes. Failure to do so results in maternal suffering and impaired child bonding, and has the potential for devastating outcomes including suicide and infanticide. Women are routinely screened for unipolar depression during or after pregnancy but not for bipolar disorder, in spite of the fact that childbirth is associated with a major risk for onset or exacerbation of bipolar disorder...

Jonathan M Meyer
There has been increasing recognition that antipsychotic nonadherence is common across all stages of schizophrenia, starting from the first episode. Moreover, numerous meta-analyses of the existing literature indicate superiority of long-acting injectable (LAI) over oral antipsychotics when one adjusts for the greater illness severity and duration among patients in LAI antipsychotic trials. The increasing availability of LAI antipsychotic options has raised interest in converting patients from oral medication; however, the successful transition from oral to the comparable LAI antipsychotic requires an understanding of the current extent of antipsychotic exposure, the kinetics of the LAI preparation, and the expected plasma levels achieved by the LAI formulation...

Obesity is becoming an increasing problem worldwide. In addition to causing many physical health consequences, there is increasing evidence demonstrating that obesity is toxic to the brain and, as such, can be considered a disease of the central nervous system. Peripheral level regulators of appetite, such as leptin, insulin, ghrelin, and cholecystokinin, feed into the appetite center of the brain, which is controlled by the hypothalamus, to maintain homeostasis and energy balance. However, food consumption is not solely mediated by energy balance, but is also regulated by the mesolimbic reward system, where motivation, reward, and reinforcement factors influence obesity...

Migraine varies in its frequency, severity, and impact; treatment should consider these variations and the patient's needs and goals. Migraine pharmacologic treatment may be acute (abortive) or preventive (prophylactic), and patients often require both. New medication devices are available or in development, including an intracutaneous, microneedle system of zolmitriptan and sumatriptan, and breath-powered powder sumatriptan intranasal treatment. Lasmiditan, a 5-HT1F receptor agonist, is in development for acute treatment, as are small molecule calcitonin gene-related peptide (CGRP) receptor antagonists (Gepants) for acute and preventive treatment...

Tardive dyskinesia is a disturbance in the balance between dopamine receptor stimulation and dopamine receptor blockade in the motor striatum, with hypothetically too much stimulation of supersensitive D2 receptors, resulting in "don't stop" signaling to motor output.

OBJECTIVE: This post-hoc pooled analysis evaluated categorical change in functional impairment in patients with major depressive disorder (MDD) treated with desvenlafaxine versus placebo and examined whether early improvement in functioning predicted functional outcomes at study endpoint. METHODS: Data were pooled from eight randomized, double-blind, placebo-controlled studies of desvenlafaxine for the treatment of MDD, including adults who were randomly assigned to receive desvenlafaxine 50 or 100 mg/d or placebo (N=3,384)...

OBJECTIVE: Presence of negative mood (depressed mood) and anhedonia (lack of interest and pleasure) are considered core symptoms of depression, while absence of positive mood is not taken into account. It is therefore remarkable that the depression scales routinely used to assess changes during antidepressant treatment (Hamilton Depression Rating Scale [HDRS], Montgomery-Åsberg Depression Rating Scale [MADRS]) do not really take into account anhedonia. Several scales were developed to assess positive mood and hedonic tone, but they only partially cover the multidimensional concept...

OBJECTIVE: Our aim was to describe the efficacy and tolerability of pimavanserin, a highly selective serotonin 5-HT2A receptor inverse agonist/antagonist indicated for the treatment of hallucinations and delusions associated with Parkinson's disease psychosis (PDP), using the metrics of number needed to treat (NNT) and number needed to harm (NNH). METHODS: Categorical efficacy and tolerability data were extracted from the clinical trial databases of the double-blind placebo-controlled studies of pimavanserin in persons with PDP...

The habenula, which in humans is a small nuclear complex within the epithalamus, plays an essential role in regulating the intensity of reward-seeking and adversity-avoiding behavior in all vertebrate ancestors by regulating the activity of ascending midbrain monoaminergic tracts. In lampreys, considered to possess a brain comparable to humans' earliest evolutionary vertebrate ancestor, the activity of the lateral habenula is controlled by a subset of glutamatergic neurons of the animal's pallidum (habenula-projecting globus pallidus) that inhibit reward-seeking behavior when this conduct is not successful enough...

Between 1940 and 1944, an estimated 48,588 patients resident in French psychiatric hospitals died of starvation. Standard prisons, while facing similar problems, did not experience the same number of deaths by starvation, partly due to their ability to develop a black market for food and rations. Patients in psychiatric hospitals, on the other hand, were completely at the mercy of their doctors and the personnel in charge. At Hôpital du Vinatier, a psychiatric facility in Lyon, the mortality rate increased sharply from 1940 to 1944...

OBJECTIVE: Some antidepressants, such as trazodone or clomipramine, can be administered intravenously in patients with major depressive disorder (MDD), with potential benefits compared to the standard oral treatment, but available data about their efficacy are limited. The present study was aimed to compare the effectiveness of trazodone and clomipramine (intravenous [i.v.] followed by oral administration). METHODS: Some 42 patients with a diagnosis of MDD according to the DSM-5 were selected and treated with i...
