Introduction The term “Sexual and Gender Minorities” includes lesbian, gay, bisexual, transgender, queer, intersex and/or asexual populations. It was introduced in the MeSH Database in 2018. Mental health research on sexual and gender minority populations is gaining momentum. Objectives To describe mental disorders among sexual and gender minorities. Methods This is a review of the literature via Medline. The database was searched using the keyword combination “sexual gender minorities” OR “homosexuality” OR “bisexuality” OR “transgender persons” OR “intersex persons” AND “mental disorders”. The filters applied were Full text, Meta-Analysis, Systematic Review and in the last 5 years. Results A total of 59 articles were included. The lowest rates of depression and anxiety were reported among heterosexual people. Depressive symptoms, suicidality, interpersonal trauma exposure, substance use disorders, anxiety, and general distress have been consistently elevated among transgender and gender non-conforming people. Among transgender people, the prevalence of binge drinking ranged from 7%-61%. Depression was the most frequent mental disorder among sexual minority men (43.2%) followed by anxiety (32.2%), suicidal ideation (21.2%), suicide plans (6.2%) and suicide attempts (7.3%). Eating disorders were more frequent among sexual minority women compared with heterosexual peers. Compared with heterosexual youth, sexual minority youth had 123% to 623% higher odds of lifetime substance use, 82% to 317% higher odds of depressive symptoms and suicidality and 20% to 280% higher odds of violence victimization. Conclusions The prevalence of mental disorders is high among sexual and gender minorities for whom mental health prevention and treatment programs are needed.

Introduction A major increase in mental health issues was noted since the outbreak of the covid-19 pandemic even in patients with no history of mental health illness, specifically brief psychotic disorders. Objectives Establish the covid-19 pandemic circumstances as precipitating factors of psychosis independently from other stressors Methods This is a cross-sectional and descriptive study carried out in the psychiatric department of the University Hospital of Mahdia including two groups of patients over a period of 15 months: From October 2018 to December 2019 are pre-covid cases, and the second group consists of the ones admitted between June 2020 and August 2021. We have collected the data of patients diagnosed with brief psychotic disorder according to DSM-5. We have focused on two clinical characteristics of the psychotic episodes (theme of delusions, stressors). Results We have collected 19 patients, 12 among them during the pre-covid period. In our pre-covid period, brief psychotic disorder presented mostly with marked stressors (33.3%) whilst in the middle of the pandemic, marked stressors are present in only 14.3% of the cases. Which could suggest that this state of alarm can singlehandedly trigger psychosis. For the theme of delusions, in the pre-covid period, the religious theme appeared to be the most frequent (58.3%), whilst during the pandemic, persecution became the most prevalent (71.4%), showing how living in fear of contracting the virus could manifest itself in delusional content. Conclusions Living in a prolonged state of alarm is, in itself, a marked stressor, theoretically capable of increasing the psychosis rate and altering its characteristics.
