Background COVID-19 has seriously affected physical and mental health world-wide,both due to spreading of the virus and due to the socially restrictive measures most governments have enforced. Increased anxiety, stress and depressive symptoms have been widely reported in the general population. The current study investigated the effects of COVID and the restrictive measures in the Netherlands on stress, anxiety and loneliness in patients with a pre-existing psychiatric disorder.

Individuals with psychoses have brain alterations, particularly in frontal and temporal cortices, that may be particularly prominent, already at illness onset, in those more likely to have poorer symptom remission following treatment with the first antipsychotic. The identification of strong neuroanatomical markers of symptom remission could thus facilitate stratification and individualized treatment of patients with schizophrenia. We used magnetic resonance imaging at baseline to examine brain regional and network correlates of subsequent symptomatic remission in 167 medication-naïve or minimally treated patients with first-episode schizophrenia, schizophreniform disorder, or schizoaffective disorder entering a three-phase trial, at seven sites.

Negative symptoms are associated with poor clinical and psychosocial outcome in schizophrenia. Their prevalence and identification in first-episode patients remains controversial. In a large cohort of patients in the early stage of schizophrenia, schizophreniform or schizoaffective disorder, we investigated, over the different phases of the OPTiMiSE trial (baseline, 4, 10 and 22 weeks of treatment), the prevalence of negative symptoms of moderate severity, unconfounded by depression and extrapyramidal symptoms at baseline.

This study aimed to assess short-term (12 weeks) and long-term (12 months) gender differences in the outcomes of patients experiencing an episode of mania in the course of bipolar disorder. European Mania in Bipolar Longitudinal Evaluation of Medication was a 2-year, prospective, observational study of the outcomes of patients with a manic or mixed episode conducted in 14 European countries. Data were collected during the acute phase (12 weeks) and during a follow-up period (up to 12 months).

Evidence from clinical patient populations indicates that affective dysregulation is strongly associated with reality distortion, suggesting that a process of misassignment of emotional salience may underlie this connection. To examine this in more detail without clinical confounds, affective regulation-reality distortion relationships, and their clinical relevance, were examined in a German prospective cohort community study. A cohort of 2524 adolescents and young adults aged 14-24 years at baseline was examined by experienced psychologists.

Background: It has been suggested that dopamine dysfunction may play a role in bipolar disorder (BD). An indirect approach to examine this issue was developed, focusing on associations between dopamine proxy measures observed in BD (dopamine-related clinical traits using tardive movement syndromes as dopamine proxy measure of reference).

Methods: 3459 eligible bipolar patients were enrolled in an observational study.

Research suggests that cannabis use affects negatively on onset and outcome of schizophrenia, but less is known about possible effects in mood disorders. Bipolar in- and outpatients (N = 3459) were enrolled in an observational study. The influence of cannabis exposure on clinical and social treatment outcome measures was examined over the course of 1 year, as well as the effects on these associations of third mediating variables.

Background: Psychopathological heterogeneity in manic syndromes may in part reflect underlying latent classes with characteristic outcome patterns. Differential treatment course and outcome after 12 weeks of treatment were examined for three distinct classes of patients with acute mania in bipolar disorder.

Subjects And Methods: Three thousand four hundred and twenty-five patients with acute mania were divided into three distinct mania classes: 'Typical', 'Psychotic' and 'Dual' (i.

Background: Knowledge of moderators of symptom improvement over time in acute mania improves predictability of individual patient outcomes. This study attempted to identify such moderators of the rate of symptom improvement.

Methods: In 3459 patients with high levels of mania in whom a change in psychotropic treatment was initiated and who were assessed six times over three months, clinical and social moderators of the rate of response were examined.

Background: Patterns of low heart rate, skin conductance and cortisol seem to characterise children with disruptive behaviour disorder (DBD). Until now, the startle paradigm has not been used in DBD children. We investigated whether DBD children, like adult psychopaths, process emotional stimuli in an abnormal way.
