Bipolar disorder, which often has its onset in adolescence or early adulthood, is characterised by marked variations in mood, ranging from major depressive episodes to manic exacerbations. Compared to depressive episodes, manic recurrences are often brief and usually respond to anti-manic medications within a few weeks. Infrequently bipolar patients get badly affected by protracted manic symptoms that exhibit resistance to the usual anti-manic agents. As mania is a very disruptive condition with severe and adverse consequences for the patient, every effort should be made to bring it under control as soon as possible. Nonetheless, an occasional patient may require prolonged and persistent treatment to attain remission. In a case where manic symptoms are showing resistance, an evidence-based pharmacotherapuetic approach by the treating physician is essential. The provision of psychological and social support to the patient is vital in conjunction with biological measures for optimal management.

There is an ongoing need to identify novel pharmacological agents for the effective treatment of depression. One emerging candidate, which has demonstrated rapid-acting antidepressant effects in treatment-resistant groups, is nitrous oxide (NO)-a gas commonly used for sedation and pain management in clinical settings and with a range of pharmacological effects, including antagonism of NMDA glutamate receptors. A growing body of evidence suggests that subanaesthetic doses of NO (50%) can interfere with the reconsolidation of maladaptive memories in healthy participants and across a range of disorders.

Bipolar disorder (BD) is a severe mental illness characterized by recurrent episodes of depression and mania. Lithium is the gold standard pharmacotherapy for BD, but outcomes are variable, and the relevant therapeutic mechanisms underlying successful treatment response remain uncertain. To identify synaptic markers of BD and lithium response, we measured the effects of lithium on induced pluripotent stem cell-derived neurons from BD patients and controls.

Major Depressive Disorder (MDD) is a prevalent mental health condition that often begins in adolescence, with significant long-term implications. Indicated prevention programs targeting adolescents with mild symptoms have shown efficacy, yet the methods for identifying at-risk individuals need improvement. This study aims to evaluate the utility of Partial Least Squares Regression (PLSR) in predicting the onset of MDD among non-depressed adolescents, compared to traditional screening methods.
