Insomnia Disorder (ID) is defined as the predominant dissatisfaction with the quantity or quality of sleep associated with difficulty in initiating or maintaining sleep or early-morning awakenings with the inability to go back to sleep.

Cognitive-behavioural therapy (CBT) is the preferred treatment in cases of chronic insomnia disorder in adults.Open pragmatic study of 32 patients after eight sessions of group CBT for insomnia.Remission (insomnia severity index: 0-7 points) and response (insomnia severity index drops to8) were 31.3% and 46.9% at one month (n = 32) and 42.8% and 52.4% at one year (n = 21), respectively, with an effect size of 1.9 at one month and 2.3 at one year. At one month, 40.6% met the criteria for a case of insomnia (according to the insomnia symptoms questionnaire), and at one year, 19%, with a significant improvement in the symptoms at night and the consequences during the day. The questions of the Pittsburgh Sleep Quality Index on insomnia and sleep efficiency also improved. The pre-sleep arousal scale (n = 7) showed a shift from significant somatic and cognitive arousal to no arousal at one month. In the sleep diaries, total sleep time increased by an average of 53 minutes at one month (n = 14) and 76 minutes at one year (n = 10), with an increase of more than 10% in 71.4% of patients at one month and at one year, and an average sleep efficiency of more than 85%. The effect size for total sleep time and sleep efficiency was between 0.7 and 1.Group CBT for insomnia appears to be an effective treatment option in a clinical setting.Terapia grupal cognitivo-conductual para el insomnio: evaluación de resultados tras su introducción en un departamento de salud.Introducción. La terapia cognitivo-conductual (TCC) es el tratamiento de elección en el trastorno de insomnio crónico en adultos. Pacientes y métodos. Estudio pragmático abierto de 32 pacientes tras ocho sesiones de TCC grupal para el insomnio. Resultados. La remisión (índice de gravedad del insomnio: 0-7 puntos) y la respuesta (caída del índice de gravedad del insomnio8) fue del 31,3% y 46,9% al mes (n = 32) y del 42,8% y 52,4% al año (n = 21), respectivamente, con un tamaño del efecto de 1,9 al mes y 2,3 al año. Al mes, el 40,6% cumplía criterios de caso de insomnio (según el cuestionario de síntomas de insomnio), y al año, el 19%, con una mejoría significativa de síntomas nocturnos y consecuencias diurnas. También mejoraron las preguntas del índice de calidad de sueño de Pittsburgh sobre el insomnio y la eficiencia del sueño. La escala de activación previa al sueño (n = 7) mostró un trasvase desde activación significativa somática y cognitiva a ausencia de activación al mes. En los diarios de sueño, el tiempo total de sueño aumentó 53 minutos de media al mes (n = 14) y 76 al año (n = 10), con un aumento superior al 10% en el 71,4% de los pacientes al mes y al año, y una eficiencia del sueño media superior al 85%. El tamaño del efecto para el tiempo total de sueño y la eficiencia del sueño estuvo entre 0,7 y 1. Conclusiones. La TCC grupal para el insomnio parece una opción terapéutica eficaz en un entorno clínico.

Most previous longitudinal studies of functional magnetic resonance imaging (fMRI) in first-episode psychosis (FEP) using cognitive paradigm task found an increased activation after antipsychotic medications. We designed an emotional auditory paradigm to explore brain activation during emotional and nonemotional word processing. This study aimed to analyze if longitudinal changes in brain fMRI BOLD activation is present in patients vs. healthy controls. A group of FEP patients (n = 34) received clinical assessment and had a fMRI scan at baseline and follow-up (average, 25-month interval). During the fMRI scan, both emotional and nonemotional words were presented as a block design. Results were compared with a pair of healthy control group (n = 13). Patients showed a decreased activation at follow-up fMRI in amygdala (F = 4.69; p = 0.04) and hippocampus (F = 5.03; p = 0.03) compared with controls. Middle frontal gyrus was the only area that showed a substantial increased activation in patients (F = 4.53; p = 0.04). A great heterogeneity in individual activation patterns was also found. These results support the relevance of the type of paradigm in neuroimaging for psychosis. This is, as far as we know, the first longitudinal study with an emotional auditory paradigm in FEP. Our results suggested that the amygdala and hippocampus play a key role in psychotic disease. More studies are needed to understand the heterogeneity of response at individual level.

Background: Little is known about changes in brain functioning after first-episode psychosis (FEP). Such knowledge is important for predicting the course of disease and adapting interventions. Functional magnetic resonance imaging has become a promising tool for exploring brain function at the time of symptom onset and at follow-up. Method: A systematic review of longitudinal fMRI studies with FEP patients according to PRISMA guidelines. Resting-state and task-activated studies were considered together. Results: Eleven studies were included. These reported on a total of 236 FEP patients were evaluated by two fMRI scans and clinical assessments. Five studies found hypoactivation at baseline in prefrontal cortex areas, two studies found hypoactivation in the amygdala and hippocampus, and three others found hypoactivation in the basal ganglia. Other hypoactivated areas were the anterior cingulate cortex, thalamus and posterior cingulate cortex. Ten out of eleven studies reported (partial) normalization by increased activation after antipsychotic treatment. A minority of studies observed hyperactivation at baseline. Conclusions: This review of longitudinal FEP samples studies reveals a pattern of predominantly hypoactivation in several brain areas at baseline that may normalize to a certain extent after treatment. The results should be interpreted with caution given the small number of studies and their methodological and clinical heterogeneity. (C) 2019 Published by Elsevier Masson SAS.
