Psylocibin

The recognition of emotions in facial expressions (REFE) is a core construct of social cognition. In the last decades, studies have showed that REFE is altered in major depressive disorder (MDD), but the evidence is conflicting. Thus, we conducted a systematic review of clinical trials involving therapeutic interventions in MDD and any evaluation of REFE to update (2018-2023) and systematically evaluate the evidence derived from controlled clinical trials on the effects of therapeutic strategies to MDD on the REFE...

The available interventions for people who are at risk of suicide have limited efficacy. Recently, research on new mental health treatments has started to consider psychedelic compounds, particularly psilocybin, a molecule with a few thousand years of history of use in human societies. The possible effects of psilocybin on suicidal ideation and behaviors have not been specifically studied yet; however, the current knowledge on the suicidal process and the available data on es/ketamine suggest that psylocibin could be used to modulate the thoughts and behavioral patterns in individuals who are at risk of suicidal behaviors...

The United Nations estimates that the world's population will reach 8.5 billion by 2030, and the populations of most countries are expected to grow older. This is case for many developed countries, including Australia, the United Kingdom, Canada, the United States of America, and member states of the European Union. Older cohorts will comprise a larger proportion of overall populations, driven in part by our increases in life expectancy. An ageing population poses challenges for governments; notably, older people tend to have multiple, chronic health conditions which can place a burden of health budgets...

The recurrence of flashbacks without acute or chronic hallucinogen consumption has been recognized in the DSM IV criteria as the hallucinogen persisting perception disorder (HPPD). Perceptual disturbances may last for 5 years or more and represent a real psychosocial distress. We reported here a case of a 18-year-old young man presenting HPPD after a mixed intoxication with psylocibin and cannabis. This report shows symptomatic recurrences persisting more than 8 months. Various differential diagnoses were evoked and our therapeutic strategies were described...
