Distinct and shared contributions of diagnosis and symptom domains to cognitive performance in severe mental illness in the Paisa population: a case-control study.

BACKGROUND: Severe mental illness diagnoses have overlapping symptomatology and shared genetic risk, motivating cross-diagnostic investigations of disease-relevant quantitative measures. We analysed relationships between neurocognitive performance, symptom domains, and diagnoses in a large sample of people with severe mental illness not ascertained for a specific diagnosis (cases), and people without mental illness (controls) from a single, homogeneous population. METHODS: In this case-control study, cases with severe mental illness were ascertained through electronic medical records at Clínica San Juan de Dios de Manizales (Manizales, Caldas, Colombia) and the Hospital Universitario San Vicente Fundación (Medellín, Antioquía, Colombia). Participants were assessed for speed and accuracy using the Penn Computerized Neurocognitive Battery (CNB). Cases had structured interview-based diagnoses of schizophrenia, bipolar 1, bipolar 2, or major depressive disorder. Linear mixed models, using CNB tests as repeated measures, modelled neurocognition as a function of diagnosis, sex, and all interactions. Follow-up analyses in cases included symptom factor scores obtained from exploratory factor analysis of symptom data as main effects. FINDINGS: Between Oct 1, 2017, and Nov 1, 2019, 2406 participants (1689 cases [schizophrenia n=160; bipolar 1 disorder n=519; bipolar 2 disorder n=204; and major depressive disorder n=806] and 717 controls; mean age 39 years (SD 14); and 1533 female) were assessed. Participants with bipolar 1 disorder and schizophrenia had similar impairments in accuracy and speed across cognitive domains. Participants with bipolar 2 disorder and major depressive disorder performed similarly to controls, with subtle deficits in executive and social cognition. A three-factor model (psychosis, mania, and depression) best represented symptom data. Controlling for diagnosis, premorbid IQ, and disease severity, high lifetime psychosis scores were associated with reduced accuracy and speed across cognitive domains, whereas high depression scores were associated with increased social cognition accuracy. INTERPRETATION: Cross-diagnostic investigations showed that neurocognitive function in severe mental illness is characterised by two distinct profiles (bipolar 1 disorder and schizophrenia, and bipolar 2 disorder and major depressive disorder), and is associated with specific symptom domains. These results suggest the utility of this design for elucidating severe mental illness causes and trajectories. FUNDING: US National Institute of Mental Health.

Salud sexual y reproductiva de los pacientes con esquizofrenia y trastorno afectivo bipolar / Sexual and Reproductive Health in Patients with Schizophrenia and Bipolar Disorder

RESUMEN Introducción: Las personas con esquizofrenia y trastorno afectivo bipolar (TAB) tienen alto riesgo de embarazos no deseados y abortos, debido a su condición de vulnerabilidad o comportamientos hipersexuales (frecuentes en este último trastorno); a esto se asocia dificultad en la planeación de sus actos y escasez de educación sexual y consejos del personal médico, lo cual lleva a resultados obstétricos negativos e incapacidad para cuidar adecuadamente a sus hijos. Objetivo: Describir las características de una muestra de pacientes con trastorno bipolar y esquizofrenia en Medellín, Colombia, sobre salud sexual y reproductiva, el uso de anticoncepción y el asesoramiento al respecto en las consultas de psiquiatría. Métodos: Se realizó un estudio observacional de corte transversal. Se incluyó a los 160 participantes del ensayo clínico «Los Efectos de un Programa de Intervención Multimodal en Pacientes con Trastorno Afectivo Bipolar y Esquizofrenia¼, captados de la consulta del grupo de trastornos del ánimo y psicosis del Hospital Universitario San Vicente Fundación de Medellín. Un residente de tercer año de Psiquiatría contactó con ellos vía telefónica y les aplicó una encuesta acerca de las características de su vida sexual y reproductiva y la anticoncepción. Resultados: Casi todos los pacientes con esquizofrenia estaban solteros, no tenían estudios de pregrado y se encontraban desempleados. No se encontraron diferencias significativas en cuanto a la edad de inicio de las relaciones sexuales al comparar por diagnóstico y por sexo. Casi todos los pacientes con esquizofrenia y casi la mitad de los pacientes con TAB reportaron no tener vida sexual activa. Casi todos los que reconocieron tenerla afirmaron que usaban siempre algún método anticonceptivo; del grupo de TAB, solo el 48,8% de las mujeres solteras reconocieron estar planificando y poco más de la mitad de los varones afirmaron que se servían del condón en sus relaciones sexuales. Una cuarta parte de los embarazos fueron no planeados. El 57,4% de los pacientes con TAB y el 78,8% de los que tenían esquizofrenia se consideraban bien informados sobre planificación familiar, a pesar de que la mayoría afirmaba que nunca habían recibido información sobre este tema durante las consultas con su psiquiatra. Conclusiones: Los pacientes con enfermedad mental tienen alteraciones cognitivas y conductuales que afectan a su vida sexual y reproductiva, por lo cual los psiquiatras deben abordar este tema para garantizar la educación en cuanto a anticoncepción, planeación de la natalidad y riesgo de enfermedades de transmisión sexual, entre otras, y así velar por la seguridad y la calidad de vida de sus pacientes.

ABSTRACT Introduction: People with schizophrenia and bipolar disorder (BD) have a high risk of unwanted pregnancies and abortions, due to their condition of vulnerability or hypersexuality (common in BD). This is associated with difficulty in planning their actions and lack of sex education and counselling by medical personnel, and can lead to adverse obstetric outcomes and inability to care adequately for their children. Objective: To describe the characteristics in terms of sexual and reproductive health, and the use of contraception and counselling in psychiatric consultations, in a sample of patients with BD and schizophrenia in Medellin, Colombia. Methods: Observational cross-sectional study. We included the 160 participants from the clinical trial, "The effects of a multimodal intervention programme in patients with bipolar disorder and schizophrenia", who were recruited from the mood and psychosis disorders group clinic at Hospital Universitario de San Vicente Fundación in Medellin. They were contacted by phone by a third-year psychiatry resident, who applied a survey about the characteristics of their sex life, contraception and reproduction. Results: Almost all of the patients with schizophrenia were single, had no undergraduate studies and were unemployed. No significant differences were found regarding the age of starting sexual relations when comparing by diagnosis and gender. Almost all patients with schizophrenia and almost half of the patients with BD reported not having an active sexual life. Almost all of those who admitted to having an active sexual life claimed to always use contraception; in the BD group, only 48.8% of single women admitted to using contraception and a little over half of men stated that they used a condom when having sex. A quarter of the pregnancies were unplanned. Although the majority of the patients stated that they had never received information about family planning in the consultations with their psychiatrist, 57.4% of the patients with BD and 78.8% of those who had schizophrenia, considered themselves to be well informed on the subject. Conclusions: Patients with mental illness have cognitive and behavioural alterations that affect their sexual and reproductive lives. Psychiatrists should therefore address this issue, to ensure education in areas such as contraception, family planning and sexually transmitted diseases and help safeguard the safety and quality of life of their patients.
