Emotions and behaviours of child and adolescent psychiatric patients during the COVID-19 pandemic.

Background: Previous pandemics have had negative effects on mental health, but there are few data on children and adolescents who were receiving ongoing psychiatric treatment.

Aims: To study changes in emotions and clinical state, and their predictors, during the COVID-19 pandemic in France.

Method: We administered (by interview) the baseline Youth Self-Report version of the CoRonavIruS Health Impact Survey v0.

Changes in the Use of Emergency Care for the Youth With Mental Health Problems Over Decades: A Repeated Cross Sectional Study.

To understand whether changes exist in the types of youths mental health problems addressed in emergency in a context of increasing demand, we conducted a retrospective chart review in an emergency care outpatient unit. Data from children and adolescents admitted at four different time periods (years 1981, 1992, 2002, and 2017) were compared to determine trends in terms of patients' characteristics, nature of the mental health problems and final care decisions. Between 1981 and 2017 there was a 3.

Early interventions for youths at high risk for bipolar disorder: a developmental approach.

In recent decades, ongoing research programmes on primary prevention and early identification of bipolar disorder (BD) have been developed. The aim of this article is to review the principal forms of evidence that support preventive interventions for BD in children and adolescents and the main challenges associated with these programmes. We performed a literature review of the main computerised databases (MEDLINE, PUBMED) and a manual search of the literature relevant to prospective and retrospective studies of prodromal symptoms, premorbid stages, risk factors, and early intervention programmes for BD.

Treatment use in a prospective naturalistic cohort of children and adolescents with catatonia.

We aimed to (1) describe the treatment used in a large sample of young inpatients with catatonia, (2) determine which factors were associated with improvement and (3) benzodiazepine (BZD) efficacy. From 1993 to 2011, 66 patients between the ages of 9 and 19 years were consecutively hospitalized for a catatonic syndrome. We prospectively collected sociodemographic, clinical and treatment data.

Patients' perspectives on residual symptoms in bipolar disorder: a focus group study.

Euthymic bipolar patients are often impacted by residual symptoms (RSs) that increase the risk of relapse or low functioning. We aimed to identify the perceptions of RSs, barriers to management, and service needs in euthymic bipolar patients. A qualitative methodology (focus group) was used.

Association between circadian genes, bipolar disorders and chronotypes.

Abnormalities in circadian rhythms play an important role in the pathogenesis of bipolar disorders (BD). Previous genetic studies have reported discrepant results regarding associations between circadian genes and susceptibility to BD. Furthermore, plausible behavioral consequences of at-risk variants remain unclear since there is a paucity of correlates with phenotypic biomarkers such as chronotypes.

Residual symptoms and functional performance in a large sample of euthymic bipolar patients in France (the OPTHYMUM study).

Background: Some residual symptoms were found to be associated with impaired functioning in euthymic bipolar patients, but their impact and relevance are unclear in clinical practice. We re-examined the functional influence of a large set of residual symptoms in 525 euthymic bipolar outpatients using self- and clinician-rated questionnaires (OPTHYMUM study).

Methods: This was a multi-centre, cross-sectional, non-interventional study of adult bipolar outpatients.

Circadian abnormalities as markers of susceptibility in bipolar disorders.

Chronobiological models have contributed to a better understanding of the pathophysiology of bipolar disorders. Circadian functions dysregulations are associated with bipolar disorders, including biochemical (melatonin and cortisol profiles), actigraphic (sleep/wake patterns), and dimensional (chronotypes) circadian markers. These associations are observed not only during acute episodes but also during euthymic periods.

Chronotypes of bipolar patients in remission: validation of the French version of the circadian type inventory in the FACE-BD sample.

Circadian rhythm disturbances have been associated with bipolar disorder (BD) during both the mood episodes and the periods of remission. Circadian phase preferences for the evening have been reported for remitted patients, whereas the amplitude and stability of their rhythms have never been assessed using questionnaires. The primary aim of our study was the validation of a French version of the Circadian Type Inventory (CTI), whereas its secondary aim was the comparison between remitted patients with BD and healthy controls for rhythm stability and amplitude and for phase preference.

Genetics of circadian rhythms and mood spectrum disorders.

Mood spectrum disorders (bipolar disorder, recurrent depressive disorder and seasonal affective disorder) are accompanied by circadian deregulations, which can occur during acute mood episodes as well as during euthymic periods, and are particularly common among bipolar patients in remission. This suggests that altered circadian rhythms may be biological markers of these disorders. Rhythm dysfunctions have been observed in mood disorder patients by using actigraphic measures and by assessing social metric rhythms, diurnal preferences and melatonin secretion.

Circadian biomarkers, circadian genes and bipolar disorders.

Bipolar disorders are associated with circadian deregulations both during acute mood episodes and during euthymic periods, suggesting that these circadian rhythms may represent trait markers of the disease. Several arguments demonstrate that deregulations of circadian rhythms may be part of the pathophysiology of bipolar disorders. Abnormal quantitative and qualitative circadian disturbances have been repeatedly showed in bipolar patients, both during euthymic periods and acute phases, using different assessment tools such as actigraphy, polysomnography, and blood melatonin monitoring.
