Social cognition interventions for adolescents with autism spectrum disorder. A systematic review.

Early intervention during childhood in patients with Autism Spectrum Disorder (ASD) has been strongly advocated. As adolescence is reached, new, more complex social demands emerge. These demands require a therapeutic approach that has not been widely studied. The aim of this review is to examine and synthesize the existing literature on social cognition interventions in adolescence and lay the groundwork for future interventions.

Trends in the incidence of hospital-treated suicide attempts during the COVID-19 pandemic in Oviedo, Spain.

BACKGROUND: The potential impact of the COVID-19 pandemic on suicidal behavior has generated predictions anticipating an increase in suicidal tendencies. The aim of this research is to study its influence on the incidence of hospital-treated suicide attempts throughout the year 2020 in Oviedo, Spain. METHODS: Data were collected on all patients admitted to the emergency department of Central University Hospital of Asturias in Oviedo for attempted suicide during 2020. Incidence rates were calculated for three lockdown periods. Suicide attempt trends in 2020 were compared with a non-COVID-19 year (2009) to avoid seasonal variations bias. Chi-square and Fisher's exact tests were performed. The influence of COVID-19 incidence in Oviedo was analyzed using Spearman's correlation coefficient. RESULTS: The cumulative incidence rate of attempted suicide per 100,000 person-years was 136.33 (pre-lockdown), 115.15 (lockdown), and 90.25 (post-lockdown) in adults (over 19 years old), and 43.63 (pre-lockdown), 32.72 (lockdown), and 72.72 (post-lockdown) in adolescents (10-19 years old). No association was found with COVID-19 incidence rates (Spearman's rho -0.222; p = 0.113). Comparing the years 2020 and 2009, statistically significant differences were observed in adolescents (Fisher's exact test; p = 0.024), but no differences were observed in adults (chi-square test = 3.0401; p = 0.218). CONCLUSIONS: Hospital-treated suicide rates attempted during the COVID-19 outbreak in Oviedo, Spain showed a similar trend compared with a non-COVID-19 year. In contrast, the number of adolescents hospital-treated for attempted suicide increased during lockdown, suggesting more vulnerability to COVID-19 restrictions after the initial lockdown period in this age group.

[A proposed new target for deep brain stimulation in obsessive-compulsive disorder]. / Propuesta de una nueva diana para la estimulación cerebral profunda en el trastorno obsesivo-compulsivo.

INTRODUCTION: The obsessive-compulsive disorder (OCD) has an incidence in general population of 1.5-3%. If we consider as a positive respond a diminution of the 25-35% in the symptoms of OCD according to the Y-BOCS, and we add the cognitive-behavioral therapy to the pharmacological treatment, only a 40-60% of treated patients would have significant improvement and a 10% of patients with OCD, would be refractory to all type of medical treatment. DEVELOPMENT: Current neurosurgical techniques for resistant cases of OCD interrupt the connections between the frontal lobes and subcortical structures (cingulotomy, capsulotomy). These techniques are ablative and irreversible. It shows the importance of finding a less aggressive technique with better clinical results. Deep brain stimulation (DBS) is an alternative to traditional neurosurgery based in neuromodulation methods. It's considered that the physiopathology of the OCD consists of a dysfunction of the direct and indirect vias that control the extrapiramidal limbic circuit. On the other hand, it had been obtained positive results after DBS of the subthalamic nucleus of three patients with Parkinson's disease and OCD. CONCLUSION: This article has as target the demonstration that bilateral DBS of the limbic part of the subthalamic nucleus is an alternative for the treatment of refractory OCD.

[Review of the target for the deep brain stimulation of chronic cluster headache]. / Revision de la diana para la estimulacion cerebral profunda de la cefalea en racimos cronica.

Cluster headache is included in the group of trigeminal autonomic cephalalgias. Although the pathophysiology of cluster headache has not yet been sufficiently established, the theory of a central origin tells us that this headache is produced by hypothalamic dysfunction. More than 50 patients have been treated with deep brain stimulation of the posterior nucleus of the hypothalamus from 2001. The results show clinical improvement in more than 60% of the cases, opening a promising issue for the treatment of the cluster headache persistent after medical treatment. The surgical target that have been used until now is based on the origin of the cluster headache in the hypothalamic dysfunction. Nevertheless, It has still some open questions as the lack of proving the posterior nucleus of the hypothalamus is the real origin of the cluster headache, the lack of consensus about the anatomy of the surgical target and the variability of the structures stimulated with the surgery. The aim of this article is a review of the target used and propose another surgical target based on physiopathological concepts to explain the improvement with the deep brain stimulation in these patients.
