Aprendizaje y memoria verbal: Comparación entre pacientes con trastorno por consumo de alcohol y trastorno de depresión mayor / Learning and verbal memory: A comparison between patients with alcohol use disorder and major depressive disorder

El daño cerebral relacionado con el consumo de alcohol se asocia a alteraciones de las funciones cognitivas, entre las que destacan memoria y aprendizaje verbal. El objetivo principal es evaluar memoria y aprendizaje verbal en una muestra de 111 pacientes con trastorno por consumo de alcohol (TCA) versus 78 con trastorno de depresión mayor (TDM) y 100 controles sanos. La evaluación incluyó variables sociodemográficas y clínicas, la Escala de Hamilton para la Depresión (HDRS) y el Test de Aprendizaje Verbal de California (CVLT). Se utilizó ANOVA de un factor para comparaciones entre los 3 grupos y ANCOVAS bidireccionales incluyendo diferentes covariables. El ANOVA de un factor muestra que los pacientes con TCA y TDM obtienen puntuaciones similares entre sí e inferiores a las del grupo control (p < 0,001), con excepción del CVLT Guiado (peores puntuaciones en TDM vs TCA, p < 0,001). Tras incluir como covariables la edad, sexo y los años de estudios completados, persisten las diferencias entre los grupos de TCA y TDM frente al grupo control (p ≤ 0,003) en todos los índices con excepción del CVLT Libre Inmediato y del CVLT Guiado (peor rendimiento en TDM vs TCA, p = 0,022 y p = 0,035, respectivamente). En el segundo ANCOVA, tras controlar por gravedad de la depresión, únicamente se detectan diferencias entre los pacientes con TCA y los controles sanos (p ≤ 0,007). Los pacientes con TCA presentan una importante alteración en aprendizaje y memoria verbal al compararlos con pacientes con TDM y con personas sanas. (AU)

Brain damage related to alcohol consumption is associated with impairments in cognitive functions, among which memory and verbal learning stand out. The main objective is to evaluate memory and verbal learning in a sample of 111 patients with alcohol use disorder (AUD) versus 78 with major depressive disorder (MDD) and 100 healthy controls. The evaluation included sociodemographic and clinical variables, the Hamilton Depression Scale (HDRS) and the California Verbal Learning Test (CVLT). One-way ANOVA was used for comparisons between the 3 groups and two-way ANCOVAS including different covariates. The one-way ANOVA shows that patients with AUD and MDD had scores similar to each other and lower than those of the control group (p <0.001), with the exception of the Cued CVLT (worse scores in MDD vs AUD, p <0.001). After including age, sex and years of completed studies as covariates, the differences between the AUD and MDD groups persisted compared to the control group (p ≤ 0.003) in all indices except for the Immediate Free CVLT and the Cued CVLT (worse performance in MDD vs AUD, p = 0.022 and p = 0.035, respectively). In the second ANCOVA, after controlling for depression severity, differences were only detected between AUD patients and healthy controls (p ≤ 0.007). Patients with AUD present a significant impairment in learning and verbal memory when compared with patients with MDD and with healthy people. (AU)

A 35-year follow-up study of patients admitted to methadone treatment between 1982-1984 in Asturias, Spain. / Estudio de seguimiento de 35 años de pacientes admitidos a tratamiento con metadona entre 1982-1984 en Asturias, España.

The objective was to evaluate outcomes in a heroin-dependent population 35 years after first enrolment in methadone maintenance treatment (MMT).  An ad hoc protocol was used to assess drug misuse, treatment, and drug-related morbidity in the survivor sample. The standardized mortality ratio (SMR) and 95% confidence interval (CI) were calculated.  A total of 214 heroin-dependent patients entered MMT between 1982 and 1984 in the Asturias Public Health Service. Information was received on 195 subjects, of whom 146 were deceased.  Men accounted for 77.5% of the study cohort. Over the 35-year follow-up period, the SMR was 11.75 (95% CI = 9.95 - 13.77). In the survivor sample, 5.7% were still enrolled in MMT; human immunodeficiency virus (HIV) was diagnosed in 38.77% and hepatitis B/C in 73.46%. No differences were found between sexes in mortality or HIV and hepatitis B/C status. None of the female survivors were using heroin at the 35-year follow-up compared with 5.26% of males. In conclusion, our study confirms the high long-term mortality rate of heroin addicts, even after enrollment in MMT.

El objetivo fue evaluar el estado de una población dependiente a la heroína 35 años después de su primera inscripción en un tratamiento de mantenimiento con metadona (TMM). Se utilizó un protocolo ad hoc para evaluar morbilidad, consumo y tratamiento de la adicción en la muestra de supervivientes. Se calculó la razón de mortalidad estandarizada (RME) con un intervalo de confianza (IC) del 95%. Un total de 214 pacientes ingresaron en TMM entre 1982 y 1984 en el Servicio de Salud Pública de Asturias. Se recibió información sobre 195 sujetos, de los cuales 146 habían fallecido. Los hombres representaron el 77,5% de la cohorte del estudio. Durante el período de seguimiento de 35 años, la RME fue de 11,75 (IC 95% = 9,95 ­ 13,77). En la muestra de supervivientes, el 5,7% todavía estaba inscrito en TMM; el virus de inmunodeficiencia humana (VIH) se diagnosticó en un 38,77% y la hepatitis B/C en un 73,46%; el consumo actual de heroína se informó en un 4,1%. No hubo diferencias de género en la mortalidad o la condición de VIH y hepatitis B/C. Ninguna de las mujeres consumía heroína en el seguimiento de 35 años en comparación con el 5,26% de los hombres. En conclusión, nuestro estudio confirma la alta tasa de mortalidad a largo plazo, incluso después de la inscripción en TMM.

Validation of a European Spanish adaptation of the Apathy Evaluation Scale-self-rated version (AES-S) in patients with schizophrenia.

INTRODUCTION: Apathy is a negative symptom of schizophrenia and is associated with poor real world functioning. Therefore, it is important to have validated psychometric instruments to assess this symptom. This is the first study to validate the Spanish adaptation of the self-rated version of the Apathy Assessment Scale (AES-S) in patients with schizophrenia. MATERIALS AND METHODS: Naturalistic, cross-sectional, validation study in 104 patients with schizophrenia evaluated using the following scales: Clinical Global Impression-Severity (CGI-S), Personal and Social Performance (PSP), Clinical Assessment Interview for Negative Symptoms (CAINS), Self-report of Negative Symptoms (SNS), Motivation and Pleasure Scale-Self-Report (MAP-SR), Calgary Depression Scale for Schizophrenia (CDSS), and Apathy Evaluation Scale-self-rated version (AES-S). RESULTS: Reliability: Internal consistency (Cronbach's alpha) was 0.908. Convergent validity: The Pearson correlation coefficient between AES-S and CAINS-MAP total scores was -0.483 (p<0.001). For SNS, total and avolition subscale scores were -0.803 and -0.639 (p<0.001), respectively. With the MAP-SR, the correlation coefficient was -0.727 (p<0.001). Divergent validity: The Pearson correlation coefficient between AES-S and PSP total scores was 0.504 (p<0.001). Furthermore, with the CDSS, the correlation coefficient was -0.431 (p<0.001). Discriminant validity: The AES-S discriminated between different levels of illness severity according to CGI-S scores. Factor analysis: A three-component solution explained 57.32% of the variance. Pearson correlations between coefficients were 1-2=0.265, 1-3=0.464, and 2-3=0.060. CONCLUSION: The Spanish AES-S is a reliable and valid instrument for assessing apathy in Spanish patients with schizophrenia. It seems to be appropriate for use in everyday clinical practice as a means of monitoring apathy in these patients.

The Multi-Component Smoking Cessation Support Programme (McSCSP) is effective in patients with severe mental disorder without gender differences. / El programa multicomponente de apoyo para el cese del tabaquismo (McSCSP) es efectivo en pacientes con trastorno mental grave sin diferencias de género.

High prevalence of smoking in people with severe mental disorders (SMD) contributes to their medical morbidity and reduced life expectancy. Despite the evidence of gender differences in smoking cessation, few studies have tested those differences among people with SMD. This is a non-randomized, open-label, prospective, 9-month follow-up multicentre trial to examine gender differences in the efficacy, safety and tolerability of a Multi-Component Smoking Cessation Support Programme (McSCSP). The results showed that there were no significant differences in short- (males 44.9% vs females 57.7%, chi-square = 1.112, p = 0.292) or long-term efficacy (week 24: males 40.8%, females 42.3%, chi-square = 0.016, p = 0.901; week 36: males 36.7%, females 38.5%, chi-square = 0.022, p = 0.883) between gender, neither controlled by diagnosis or treatment. Regarding safety and tolerability, there was significant increase in abdominal perimeter in males [from 105.98 (SD 13.28) to 108.52 (SD 14.01), t = -3.436, p = 0.002)], but not in females. However, there were no significant gender differences in adverse events (constipation, abnormal/vivid dreams, nausea/vomiting or skin rash/redness around patch site). In conclusion, we have demonstrated that is effective and safe to help either male or female patients with stabilized SMD to quit smoking. However, it might be a tendency in females to respond better to varenicline treatment in the short-term. Future research with larger samples is required to more clearly determine whether or not the there are differences, in addition to their reliability and robustness.

La elevada prevalencia del tabaquismo en personas con trastorno mental grave (TMG) contribuye a su morbilidad médica y reduce su esperanza de vida. A pesar de la existencia de diferencias de género en el cese del tabaquismo, pocos estudios han evaluado esas diferencias en personas con TMG. Este es un ensayo multicéntrico de seguimiento prospectivo, no aleatorizado, abierto de 9 meses para examinar las diferencias de género en la eficacia, seguridad y tolerabilidad de un programa multicomponente de apoyo para el cese del tabaquismo (McSCSP). Los resultados mostraron que no hubo diferencias de género significativas en la eficacia a corto (hombres 44,9% vs mujeres 57,7%, chi cuadrado = 1,112, p = ,292) ni a largo plazo (semana 24: hombres 40,8%, mujeres 42,0.3%, chi cuadrado = 0.016, p = ,901; semana 36: hombres 36,7%, mujeres 38,5%, chi cuadrado = 0,022, p = ,883), incluso controlando por diagnóstico o tratamiento.  Con respecto a la seguridad y la tolerabilidad, hubo un aumento significativo en el perímetro abdominal en los hombres [de 105,98 (DT 13,28) a 108,52 (DT 14,01), t = -3,436, p = ,002)], pero no en las mujeres. Sin embargo, no hubo diferencias de género significativas en los eventos adversos (estreñimiento, sueños anormales/vívidos, náuseas/vómitos o erupción cutánea/enrojecimiento alrededor de la zona del parche). En conclusión, hemos demostrado que es efectivo y seguro ayudar a los hombres y mujeres con TMG estabilizados a dejar de fumar.  Sin embargo, podría haber una tendencia en las mujeres a responder mejor al tratamiento con vareniclina a corto plazo. Se requiere investigación futura con muestras más amplias para determinar con más claridad la existencia de diferencias, además de la fiabilidad y robustez.

Cognitive functioning after six months of follow-up in a sample of alcohol use disorder outpatients. / Funcionamiento cognitivo después de seis meses de seguimiento en una muestra de pacientes ambulatorios con trastorno por uso de alcohol.

Until now, no follow-up studies had simultaneously evaluated executive functions, other non-executive functions related cognitive functions, and impulsivity in a large enough sample of moderate to severe alcohol use disorder (AUD) patients. The main objective of the present study was to compare neuropsychological performance and its relation to alcohol use in patients with AUD and healthy controls, and to determine the evolution of cognitive impairment and alcohol use over time. For this purpose, a 6-month follow-up study was designed to compare a sample of 100 outpatients with AUD (DSM-5 criteria) with 100 matched healthy controls. The patient group was recruited from three different health centres in Spain located in Orense, Gijón and Barcelona. The assessment consisted of a systematic battery of cognitive tests to evaluate the following functions: attention, anterograde memory, processing speed, verbal fluency, executive function, and implicit attitude toward alcoholic beverages. We also compared clinical variables associated with alcohol use, such as alcohol craving and impulsivity. After 6 months, anterograde memory, working memory, and resistance to interference improved remarkably in AUD patients, although not enough to match the normal population. With regard to clinical variables, there was a small but significant cognitive improvement related to a reduction in alcohol use and impulsivity. Executive dysfunction and other non-executive functions related cognitive functions impairment can be considered prognostic factors in outpatients with moderate to severe AUD.

Hasta la fecha, ningún estudio de seguimiento había evaluado simultáneamente la función ejecutiva, otras funciones no ejecutivas relacionadas con funciones cognitivas y la impulsividad en una muestra suficientemente grande de pacientes con trastorno por uso de alcohol (TUA) entre moderado y grave. Este estudio tuvo como objetivo principal comparar el desempeño neuropsicológico y su relación con el uso de alcohol en pacientes con TUA y en controles sanos, y determinar la evolución del deterioro cognitivo y el uso de alcohol a largo plazo. Con este fin, se diseñó un estudio de seguimiento de seis meses para comparar una muestra de 100 pacientes ambulatorios con TUA (criterios del DSM-5) emparejados con 100 controles sanos. Los pacientes se reclutaron de tres centros sanitarios diferentes de España, Orense, Gijón y Barcelona. La evaluación consistió en una batería sistematizada de pruebas cognitivas para evaluar las siguientes funciones: atención, memoria anterógrada, velocidad de procesamiento, fluidez verbal, función ejecutiva y actitud implícita hacia bebidas alcohólicas. También se compararon variables clínicas asociadas al consumo de alcohol, como el craving y la impulsividad. Después de seis meses, la memoria anterógrada, memoria de trabajo y resistencia a la interferencia mejoraron notablemente en los pacientes con TUA, aunque no llegaron a igualar la población general. Respecto de las variables clínicas, hubo una pequeña pero significativa mejoría cognitiva relacionada con una reducción del consumo de alcohol y de la impulsividad. La disfunción ejecutiva y otras funciones no ejecutivas relacionadas con el deterioro cognitivo pueden considerarse factores pronósticos en pacientes ambulatorios con TUA entre moderado y grave.

Are older adults also at higher psychological risk from COVID-19?

OBJECTIVE: Given the lack of information on the psychological impact of COVID-19 on people aged ≥60, we aimed to describe their psychological responses to this pandemic and lockdown situation and compare them with those under 60 years of age. METHODS: Secondary analysis of a larger online cross-sectional study designed to determine the psychological impact of the COVID-19 pandemic and lockdown across Spain. We analyzed a total of 1690 respondents aged ≥60 years and compared them with 13,363 respondents under 60 years of age. We employed the Depression, Anxiety, and Stress Scale and the Impact of Event Scale to evaluate psychological responses. RESULTS: In all, 52.6% of women and 34.3% of men were found to be probable cases of any emotional distress (p < 0.001). In both sexes, the most common psychological response was avoidance behavior (34.7% and 23.8%, respectively), followed by depression (28.5 and 14.2%). Older women and men were considered probable cases of any emotional distress less often than younger ones (women: 52.6% vs. 72.3%, p < 0.001; men: 34.3% vs. 50.6%, p < 0.001). Finally, the results of the binary logistic regression showed that only depressive and stress responses are psychological factors associated with age group [age ≥ 60 years, O.R. = 0.617 (95% CI = 0.501 - 0.759) and 0.437 (95% CI = 0.334 - 0.573), respectively]. CONCLUSION: Contrary to our hypothesis and despite the high percentage of emotional distress we found in older adults, especially women, they are actually at lower risk of developing depressive and stress consequences from COVID-19 and lockdown than those under 60 years of age. That said, we believe our results highlight the need for expert guidance in this age group, especially older women living alone.

Glutamine and New Pharmacological Targets to Treat Suicidal Ideation.

Glutamate is the major excitatory neurotransmitter in the central nervous system, and it is linked with the amino acid glutamine through a metabolic relationship of enzymatic compound interconversion and transportation, also known as the glutamate-glutamine cycle.A growing body of evidence suggests involvement of the glutamatergic neurotransmitter system in suicidal behaviours. The initial evidence comes from the pathophysiology of neuropsychiatric disorders, as disruptions in glutamate neurotransmission have been found underlying pathology in multiple suicide-related psychiatric conditions such as major depressive disorder, schizophrenia, post-traumatic stress disorder, and bipolar disorder.Existing data from experimental animal models and human in vivo studies also demonstrate that glutamate plays a key role in suicide-related personality traits including aggression and impulsive aggression.Further studies on glutamate system dysfunction underlying suicidal behaviours have focused on the different steps of the glutamate-glutamine cycle: an inflammation-mediated reduction of glutamine synthetase activity has been found in depressed suicide attempters, phosphate-activated glutaminase genes are reduced in suicide completers, and gene expression abnormalities in NMDA receptors have also been discovered in suicide victims.Evidence of a role of the glutamate-glutamine cycle in suicidal behaviours unveils new targets for anti-suicide interventions. Lithium's mechanism to reduce the risk of suicide in people with mood disorders may be related to its ability to increase glutamine synthetase, whereas novel NMDA antagonists such as ketamine [or its S(+) enantiomer esketamine] have already demonstrated positive results in reducing suicidal ideation.

It seems to be appropriate for use in everyday clinical practice as a means of monitoring apathy in these patients.

"Readiness to Change" Predicts Efficacy of Reduction among Smokers with Severe Mental Illness.

AIMS: Smoking cessation in subjects with a severe mental illness (SMI) is a challenging but attainable goal. Furthermore, the identification of variables involved in the quitting process is a highly relevant factor in clinical practice. This study aimed to analyze the influence of smokers' motivation in smoking reduction and cessation and select the most suitable way of measuring motivation. METHODS: This is a secondary analysis of a 9-month, multicenter trial examining a Multicomponent Smoking Cessation Program in 82 adult outpatients with SMI. At the end of the preparation stage, the smokers' motivational level was evaluated with the University of Rhode Island Change Assessment Scale. This allowed us to rate subjects using a continuous measure ("Readiness to Change," RTC) and group them in "Stages of Change" (SOC). Regression analyses were carried out to identify predictors of the efficacy outcomes: a reduction in at least 50% of the cigarettes smoked per day (CPD), a reduction in the expired carbon monoxide (CO), and complete abstinence from smoking. RESULTS: We studied differences in measurements of motivational levels independently (RTC and SOC) for patients who had a reduction in at least 50% of the CPD and for patients who achieved complete abstinence from smoking. However, these differences did not reach statistical significance during the follow-up study with a logistic mixed-effects model. In a linear mixed-effects model, the reduction of expired CO was significantly associated with RTC, at the end of the active treatment phase and during follow-up (ß: -1.51; SD 0.82; p < 0.01). CONCLUSION: The motivation level achieved in the preparation phase predicted the reduction of expired CO over a given period when calculated by a continuous measure (RTC).

Estadificación clínica en los trastornos mentales graves: trastorno bipolar, depresión y esquizofrenia / Clinical staging in severe mental disorders; bipolar disorder, depression and schizophrenia

La estadificación clínica es una herramienta diagnóstica utilizada en otras especialidades de la medicina que surge de la combinación de un enfoque categorial y dimensional. En las últimas 2 décadas, se ha planteado su aplicación en el campo de la psiquiatría, fundamentalmente como herramienta de ayuda diagnóstica, de orientación terapéutica y pronóstica. En este trabajo se revisan los modelos de estadificación clínica que han sido propuestos hasta la fecha para el trastorno bipolar, la depresión y la esquizofrenia. Se realizó una búsqueda bibliográfica en las bases de datos PubMed y Medline. Se seleccionaron con base en los criterios de inclusión y exclusión un total de 15 estudios. Se describen y comparan las características de cada uno de los modelos agrupados según el tipo de trastorno para el que fueron propuestos (trastorno bipolar: 4; depresión: 5; esquizofrenia: 6). Como conclusión, identificamos la necesidad de validar empíricamente dichos modelos para así demostrar que son una herramienta útil en la práctica clínica habitual

Biomarcadores sanguíneos diferenciales de las dimensiones psicopatológicas de la esquizofrenia / Differential blood-based biomarkers of psychopathological dimensions of schizophrenia

La sintomatología de la esquizofrenia es heterogénea, no existiendo ningún síntoma patognomónico de la misma. Además, su diagnóstico presenta dificultades, ya que se basa en información subjetiva en lugar de en marcadores. El propósito de este estudio es ofrecer una revisión del estado actual de los biomarcadores sanguíneos de las dimensiones psicopatológicas de la esquizofrenia. En pacientes con esquizofrenia se han observado disfunciones inflamatorias, hormonales o metabólicas y se ha intentado establecer los biomarcadores responsables de esas disfunciones. La identificación de estos podría contribuir al diagnóstico y tratamiento de la esquizofrenia (AU)

Symptomatology of schizophrenia is heterogeneous, there is not any pathognomonic symptom. Moreover, the diagnosis is difficult, since it is based on subjective information, instead of markers. The purpose of this study is to provide a review of the current status of blood-based biomarkers of psychopathological dimensions of schizophrenia. Inflammatory, hormonal or metabolic dysfunctions have been identified in patients with schizophrenia and it has attempted to establish biomarkers responsible for these dysfunctions. The identification of these biomarkers could contribute to the diagnosis and treatment of schizophrenia (AU)

Differential blood-based biomarkers of psychopathological dimensions of schizophrenia. / Biomarcadores sanguíneos diferenciales de las dimensiones psicopatológicas de la esquizofrenia.

Symptomatology of schizophrenia is heterogeneous, there is not any pathognomonic symptom. Moreover, the diagnosis is difficult, since it is based on subjective information, instead of markers. The purpose of this study is to provide a review of the current status of blood-based biomarkers of psychopathological dimensions of schizophrenia. Inflammatory, hormonal or metabolic dysfunctions have been identified in patients with schizophrenia and it has attempted to establish biomarkers responsible for these dysfunctions. The identification of these biomarkers could contribute to the diagnosis and treatment of schizophrenia.

It is feasible and effective to help patients with severe mental disorders to quit smoking: An ecological pragmatic clinical trial with transdermal nicotine patches and varenicline.

Despite the proven association between smoking and high rates of medical morbidity and reduced life expectancy in people with severe mental disorders (SMD), their smoking rates do not decline as they do in the general population. We carried out a non-randomized, open-label, prospective, 9-month follow-up multicentre trial to investigate the clinical efficacy, safety and tolerability of a 12-week smoking cessation programme for patients with SMD in the community under real-world clinical conditions. Eighty-two adult outpatients with schizophrenic/bipolar disorder smoking ≥15 cigarettes/day were assigned by shared decision between doctors and patients to transdermal nicotine patches (TNP) [36(46.2%)] or varenicline [39(50%)]. Short-term efficacy: The 12-week 7-day smoking cessation (self-reported cigarettes/day=0 and breath carbon monoxide levels≤9ppm) prevalence was 49.3%, without statistically significant differences between medications (TNP 50.0% vs varenicline 48.6%, chi-square=0.015, p=1.000). Long-term efficacy: At weeks 24 and 36, 41.3 and 37.3% of patients were abstinent, with no statistically significant differences between treatments. Safety and Tolerability: no patients made suicide attempts/required hospitalization. There was no worsening on the psychometric scales. Patients significantly increased weight [TNP 1.1(2.8) vs varenicline 2.5(3.3), p=0.063], without significant changes in vital signs/laboratory results, except significant decreases in alkaline phosphatase and low-density lipoprotein-cholesterol levels in the varenicline group. Patients under varenicline more frequently presented nausea/vomiting (p<0.0005), patients under TNP experienced skin reactions more frequently (p=0.002). Three patients under varenicline had elevated liver enzymes. In conclusion, we have demonstrated that in real-world clinical settings it is feasible and safe to help patients with stabilized severe mental disorders to quit smoking.

[Dual diagnosis in anxiety disorders: pharmacologic treatment recommendations]. / Patología dual en trastornos de ansiedad: recomendaciones en el tratamiento farmacológico.

Anxiety disorders and substance use disorders are highly comorbid (between 18% and 37%), and such comorbidity complicates treatment and worsens prognosis (including higher suicide risk). There are not many research works on the specific pharmacologic treatment of dual comorbid anxiety disorders. Most authors recommend a simultaneous approach of both, anxiety and substance use, disorders. Research data on pharmacotherapy suggest that psychotropics used in the treatment of anxiety disorders are also effective in dual diagnosis. SSRIs are considered first-line therapy in the treatment of dual anxiety while benzodiacepines should be avoided. New generation antiepileptic have shown efficacy in case series and open label studies in the latest years, thus being a promising treatment option for dual comorbid anxiety disorders, specially pregabalin in generalized anxiety disorder.

Efectos de la crisis económica en la demanda por trastornos mentales en Asturias: datos del Registro Acumulativo de Casos Psiquiátricos (2000-2010) / Effects of the economic crisis on demand due to mental disorders in Asturias: data from the Asturias Cumulative Psychiatric Case Register (2000-2010)

Introducción: La crisis económica produce efectos negativos en la salud física y mental de la población. El objetivo del presente trabajo es estudiar la asociación existente entre la situación socioeconómica y la demanda asistencial a los servicios de salud mental. Métodos: Se ha realizado un análisis de correlación de los datos de morbilidad (incidencia y prevalencia) administrativa de enfermedad mental, que fueron obtenidos del Registro Acumulativo de Casos Psiquiátricos de Asturias, y tres indicadores socioeconómicos (paro, índice de precios de consumo -IPC- y producto interior bruto -PIB- per cápita ajustado por inflación). Resultados: El incremento en la tasa de paro se asocia a una clara disminución de la demanda incidente y prevalente en salud mental. El IPC presenta una correlación positiva débil con la tasa de incidencia administrativa de algunos trastornos mentales (Trastornos neuróticos, Esquizofrenia y Toxicomanías). El PIB no presenta una correlación significativa con la demanda incidente y se asocia, de forma robusta, con un incremento de la tasa de prevalencia administrativa, más intensa en el caso del alcoholismo, trastornos neuróticos, retraso mental y demandas por códigos Z (CIE-10). Conclusión: En Asturias, la variación de los indicadores socioeconómicos observado en el presente periodo de crisis económica no se asocia con un incremento en la demanda asistencial por trastorno mental. La correlación de la tasa de desempleo con la demanda asistencial es negativa

Introduction: The economic crisis has negative effects on the population’s physical and mental health. Our objective has been to study the association between socioeconomic status and number of people demanding mental health services. Methods: We performed a correlation analysis of administrative morbidity data (incidence and prevalence) of mental illness (obtained from the Asturias Cumulative Psychiatric Case Register) and three economic indicators (unemployment, consumer price index and gross domestic product). Results: The increase in the unemployment rate is associated with a clear decrease in both new and prevalent mental health demand. CPI has a minor weak positive correlation with the administrative incidence of some mental disorders (Neurotic disorders, Schizophrenia and addictions). GDP does not show a significant correlation with the administrative incidence and it is strongly associated with an increased administrative prevalence that is more intense in the case of alcoholism, neurotic disorders, mental retardation and Z codes (ICD-10).Conclusion: The variation of the socioeconomic indicated observed in the economic crisis period in Asturias was not associated with increased care demand for any mental disorders. There is a negative correlation of unemployment rate with care demand
