Depression with and without a history of psychotic symptoms in the general population: sociodemographic and clinical characteristics.

Background: The aim of this study was to find the sociodemographic and clinical characteristics of major depressive episode (MDE) with (MDE-HPS+) and without a history of psychotic symptoms (MDE-HPS) in the general population.

Methods: The Mental Health in the General Population survey interviewed 38,694 individuals in France by using the MINI. The prevalence and sociodemographic and clinical correlates of MDE-HPS+ were assessed.

Association between coffee, tobacco, and alcohol daily consumption and sleep/wake cycle: an actigraphy study in euthymic patients with bipolar disorders.

Individuals with bipolar disorder (BD) have higher than average rates of coffee, tobacco and alcohol use. These substances may have deleterious effects on sleep quality and quantity, which may destabilize sleep/wake cycles and negatively impact the clinical course and prognosis of BD. The use of these substances may also be perceived as a self-medication attempt, for example, to induce sleep or to increase vigilance during the day.

Eveningness and poor sleep quality contribute to depressive residual symptoms and behavioral inhibition in patients with bipolar disorder.

Eveningness and sleep disturbances are considered as markers of Bipolar Disorder (BD) and influence mood and emotional or behavioral states. This study investigates the associations between circadian markers and sleep quality on residual depressive symptoms and inhibition/activation dimensions during the euthymic phase. A sample of 89 euthymic adult individuals with BD was assessed for circadian preference and typology using the Composite Scale of Morningness (CSM) and the Circadian Type Inventory (CTI) and for sleep quality using the Pittsburgh Sleep Quality Index (PSQI).

Clinical characteristics of obstructive sleep apnea in bipolar disorders.

Background: Obstructive sleep apnea (OSA) is one of the leading non-psychiatric comorbidities in bipolar disorders (BD). We sought to explore associations between risk of OSA in BD, clinical characteristics alongside with both subjective sleep complaints and objective sleep abnormalities.

Methods: Euthymic patients with BD (n = 144) were assessed over a three-week period, by actigraphy, clinical interviews and questionnaires.

[Cannabis use: what to do in general practice?].

Cannabis use is now more frequent than alcohol drinking or tobacco smoking among young people (15-34years), whereas it may induce numerous medical aftermaths. Identifying and assessing cannabis use in general practice have become a current public health issue. The two steps of screening consist in spotting risky use of cannabis, and then in checking criteria for cannabis use disorder (CUD).

The impact of discontinuing methylphenidate on weight and eating behavior.

Chronic administration of the amphetamine-derivative methylphenidate (MPH) may induce appetite reduction and weight loss. By contrast, the effects that stopping chronic MPH may exert on eating behavior and body weight are poorly known. We report the case of a male patient with childhood attention deficit/hyperactivity disorder (ADHD), who discontinued MPH treatment at the age of 11 years and was lost to follow-up until the age of 16.
