This sensation of being 'off-course' in life is an individual difference we call 'derailment.' In this article, we review derailment's unique contribution to the psychological literature, the role of perceived self and identity change in mental health, and the nuanced association between derailment and depression. Although depression has been emphasized in research to date, we argue for derailment's role in other types of mental illness, motivating several exciting directions for future work. For the pervasiveness of identity in our everyday lives, the study of derailment confers opportunities for better understanding the experience of psychopathology and approaching its treatment.Perceptual control theory states that behaviour controls perception; we act against disturbances in the environment to align hierarchically organised perceived aspects of the self and the world with neurally specified reference values. The diverse symptoms of psychopathology are each examples of loss of control, which are maintained by conflicting control systems, and effective interventions shift and sustain awareness to the source of the conflict to allow trial-and-error changes (reorganisation) in the parameters of the superordinate system to the conflict, until control is restored. Experimental, phenomenological, therapeutic and computational research has examined its mechanisms, and its mode of delivery has extended it from a client-led psychotherapy (method of levels) to brief training, group interventions and computerised modalities.Using folic acid (FA) as placebo complicates the interpretation of the findings of few RCTs evaluating safety and efficacy of hydroxychloroquine prophylaxis in COVID-19. FA is found to bind to furin-protease and spike ACE2 interface of SARS-CoV-2. In clinical studies, FA level was lowest amo
