Residual hypersomnia in unipolar and bipolar depression: A systematic review
The primary objective in managing depression is achieving full recovery, but some patients experience ongoing symptoms that affect daily life, with residual hypersomnia being notably prevalent. Understanding its extent, frequency, and potential treatments is limited.
Morphological correlates of anxiety-related experiences during a ketamine infusion
Ketamine exerts rapid antidepressant effects by enhancing neuroplasticity, particularly in the amygdala and hippocampus-regions involved in fear processing and learning. While the role of ketamine's dissociative effects in its antidepressant response is debated, anxiety experienced during infusion has been negatively correlated with treatment outcomes.
Cytokine gene polymorphisms and suicide risk in an Indian ancestral population: A case-control study
India currently accounts for a majority of global suicide deaths. Research in European ancestry has established that suicide mortality has a significant genetic component, and suggests that inflammation may play a crucial role in the pathophysiology of suicide. Inflammation is also highly relevant in regions of increased pollution exposure, such as the megacities of India. To address the existing gaps in genetic research on suicide and possible association with inflammatory biomarkers, we examined genetic polymorphism and clinical risk phenotypes in a population-based suicide-death cohort, India.
Correlations between alterations in global brain functional connectivity in patients with major depressive disorder and their genetic characteristics
This study aims to elucidate the neuroimaging changes associated with major depressive disorder (MDD) and their relationship with genetic characteristics. We conducted a global-brain functional connectivity (GFC) and genetic-neuroimaging correlation analysis on 42 MDD patients and 42 healthy controls (HCs), exploring the correlation between GFC abnormalities and clinical variables. Results showed that compared to HCs, MDD patients had significantly decreased GFC values in the bilateral posterior cingulate cortex/precuneus and increased GFC values in the left and right cerebellum Crus I/II. Additionally, a negative correlation was observed between the GFC values of the left cerebellum Crus I/II and subjective support scores, as well as social support revalued scale total scores. We identified genes associated with GFC changes in MDD, which are enriched in biological processes such as synaptic transmission and ion transport. Our findings indicate the presence of abnormal GFC values in severe depression, complementing the pathological research on the condition. Furthermore, this study provides preliminary evidence for the correlation between social support levels and brain functional connectivity, offering insights into the potential association between GFC changes and gene expression in MDD patients.

Optimisation of pharmacotherapy in psychiatry through therapeutic drug monitoring, molecular brain imaging and pharmacogenetic tests: Focus on antipsychotics
For psychotic disorders (i.e. schizophrenia), pharmacotherapy plays a key role in controlling acute and long-term symptoms. To find the optimal individual dose and dosage strategy, specialised tools are used. Three tools have been proven useful to personalise drug treatments: therapeutic drug monitoring (TDM) of drug levels, pharmacogenetic testing (PG), and molecular neuroimaging.

Effects of the combination of bone marrow stromal cells and exercise on corticosterone, BDNF, IGF-1, and anxiety-like behaviour in a rat model of post-traumatic stress disorder: Comparable effects of exercise
Post-traumatic stress disorder (PTSD) requires more effective treatment options with fewer side effects. Stem cell therapy, as a novel approach, has been investigated in the treatment of various diseases, including brain disorders. This study investigated the effects of bone marrow stromal cells (BMSCs) and the combination of BMSCs with exercise on corticosterone, BDNF and IGF-1, and anxiety-like behaviours in a male rat model of PTSD.
Subclinical hypomanic experiences in young adults after sleep deprivation are independent of depressive disorders, chronotype or 5-HTTLPR polymorphism
The acute antidepressant effect of sleep deprivation (SD) in patients with depressive disorders has been studied for more than 60 years. However, hypomanic mood swings after partial or total SD have also been described in people without diagnosed mental disorders. Studying this phenomenon in the general population may yield insights about the mechanisms of therapeutic SD, mania and bipolar disorders.
Late maternal separation provides resilience to chronic variable stress-induced anxiety- and depressive-like behaviours in male but not female mice
Maternal separation can have long-lasting effects on an individual's susceptibility to stress later in life. Maternal separation during the postnatal period is a commonly used paradigm in rodents to investigate the effects of early life stress on neurobehavioural changes and stress responsiveness. However, maternal separation during stress hyporesponsive and responsive periods of postnatal development may differ in its effects on stress resilience. Therefore, we hypothesised that late maternal separation (LMS) from postnatal day 10 to 21 in mice may have different effect on resilience than early maternal separation during the first week of postnatal life. Our results suggested that male LMS mice are more resilient to chronic variable stress (CVS)-induced anxiety and depressive-like behaviour as confirmed by the open field, light-dark field, elevated plus maze, sucrose preference and tail suspension tests. In contrast, female LMS mice were equally resilient as non-LMS female mice. We found increased expression of , , in the hypothalamus of male LMS mice whereas the opposite effect was observed in the hippocampus. LMS in male and female mice did not affect circulating corticosterone levels in response to psychological or physiological stressors. Thus, LMS renders male mice resilient to CVS-induced neurobehavioural disorders in adulthood.
