Posttraumatic stress disorder (PTSD) is a debilitating condition highly comorbid with depression. The endocannabinoid (eCB) system and brain-derived neurotrophic factor (BDNF) are suggestively involved in both disorders. We examined whether cannabinoids can prevent the long-term depressive-like symptoms induced by exposure to the shock and situational reminders (SRs) model of PTSD. The CB1/2 receptor agonist WIN55,212-2 (0.5 mg/kg; i.p.), the fatty acid hydrolase (FAAH) inhibitor URB597 (0.3 mg/kg, i.p.) or vehicle were administered 2 h after severe shock...

Mood disorders are associated to functional unbalance in mesolimbic and frontal cortical circuits. As a commonly used mood stabilizer, lithium acts through multiple biochemical pathways, including those activated by muscarinic cholinergic receptors crucial for hippocampal-prefrontal communication. Therefore, here we investigated the effects of lithium on prefrontal cortex responses under cholinergic drive. Lithium-treated rats were anesthetized with urethane and implanted with a ventricular cannula for muscarinic activation, a recording electrode in the medial prefrontal cortex (mPFC), and a stimulating electrode in the intermediate hippocampal CA1...

Mental health problems in children and adolescents include several types of emotional and behavioural disorders, including disruptive, depression, anxiety and pervasive developmental (autism) disorders, characterized as either internalizing or externalizing problems. Disruptive behavioural problems such as temper tantrums, attention deficit hyperactivity disorder, oppositional, defiant or conduct disorders are the commonest behavioural problems in preschool and school age children. The routine Paediatric clinic or Family Medicine/General Practitioner surgery presents with several desirable characteristics that make them ideal for providing effective mental health services to children and adolescents...

Background: Impaired social interaction is one of the essential features of autism spectrum disorder (ASD). Our previous copy number variation (CNV) study discovered a novel deleted region associated with ASD. One of the genes included in the deleted region is ARHGEF10 . A missense mutation of ARHGEF10 has been reported to be one of the contributing factors in several diseases of the central nervous system. However, the relationship between the loss of ARHGEF10 and the clinical symptoms of ASD is unclear...

Objectives: Social media, including online health communities, have become popular platforms for individuals to discuss health challenges and exchange social support with others. These platforms can provide support for individuals who are concerned about social stigma and discrimination associated with their illness. Although mental health conditions can share similar symptoms and even co-occur, the extent to which discussion topics in online mental health communities are similar, different, or overlapping is unknown...

Major depressive disorder (MDD) represents approximately 40% of the disability caused by mental illnesses globally. The poorly understood pathophysiology and limited efficiency of pharmacological treatment (based primarily on the principles of the monoaminergic hypothesis) make depression a serious medical, public and socio-economical problem. An increasing number of studies suggest that epigenetic modifications (alterations in gene expression that are not due to changes in DNA sequence) in certain brain regions and neural circuits represent a key mechanism through which environmental factors interact with individual's genetic constitution to affect risk of mental disorders...

INTRODUCTION: Major depressive disorder is one of the most commonly diagnosed psychiatric illnesses, and it has a profound negative impact on an individual's ability to function. Up to 90% of individuals suffering from depression also report sleep and circadian disruptions. If these disruptions are not effectively resolved over the course of treatment, the likelihood of relapse into depression is greatly increased. Cognitive Behavioural Therapy for Insomnia (CBT-I) has shown promise in treating these sleep and circadian disturbances associated with depression, and may be effective as a stand-alone treatment for depression...

OBJECTIVE: Subjective cognitive complaints are a frequent concern of patients with epilepsy. The Aldenkamp-Baker Neuropsychological Assessment Schedule (ABNAS) is a patient-reported scale validated to measure adverse cognitive effects of antiepileptic drugs (AEDs). The goals of this study were to identify predictors of patient-reported cognitive dysfunction and to assess the relationship between subjective and objective cognitive impairment. METHODS: The Cleveland Clinic Knowledge Program Data Registry was used to identify adult patients seen in outpatient epilepsy clinic from January to May 2015 and who completed the following scales: ABNAS for subjective cognitive impairment, Patient Health Questionnaire (PHQ-9) for depression, Generalized Anxiety Disorder 7-item (GAD-7) scale, Quality of Life in Epilepsy (QOLIE-10), and EuroQOL five dimensions questionnaire (EQ-5D) for health-related quality of life...

BACKGROUND: Depression and anxiety are prevalent among parents of children with autism spectrum disorder (ASD), but limited research has investigated why parenting a child with ASD is associated with elevated distress and increased risks of mental health problems. We responded to this gap in the literature by examining the associations between child autistic symptoms and parental affective symptoms, as well as the potential underlying mechanisms. Guided by a family process theory, we hypothesized that child autistic symptoms would be positively associated with parental depressive and anxiety symptoms, and that these associations would be mediated by parents' concerns about their children's characteristics (future-related worry), parental roles (parenting stress), marital relationships (marital conflicts), and family conditions (family economic pressure)...

It is estimated that between 1.7 and 2.6 million people have had intermittent explosive disorder (IED) during their life in the United States alone. Co-occurring psychiatric disorders are very common in IED, being major depressive disorder arguably the most common. The objective of this study was to examine the clinical correlates of IED and depressive manifestations in 74 treatment-seeking subjects. After controlling for confounders, there were associations between major depressive disorder and severity of depressive symptoms, and (a) higher assault scores, (b) more severe hostile behavior and (c) worse social adjustment...

Inflammation has been implicated in a variety of psychiatric disorders. We aimed to determine whether levels of complement C5 protein in the cerebrospinal fluid (CSF), which may reflect activation of the complement system in the brain, are altered in patients with major psychiatric disorders. Additionally, we examined possible associations of CSF C5 levels with clinical variables. Subjects comprised 89 patients with major depressive disorder (MDD), 66 patients with bipolar disorder (BPD), 96 patients with schizophrenia, and 117 healthy controls, matched for age, sex, and ethnicity (Japanese)...

L Lerousseau
Excessive daytime sleepiness is a major symptom in cases of the obstructive sleep apnea-hypopnea syndrome. Most often, it is vastly improved by treatment with continuous positive airway pressure (CPAP). The most effective way to confirm its disappearance is through wakefulness maintenance testing. If residual sleepiness remains, despite CPAP, further diagnostic investigation must be carried out. Firstly, it must be assessed whether the treatment is fully effective (apnea hypopnea index<10/h) by examining flow limitations under treatment (polysomnography) and whether it is sufficiently used (>6h/night)...
