Mujeres con depresión sueñan menos



La capacidad de soñar se ve severamente afectada entre mujeres que experimentan depresión clínica y, en caso de soñar, las emociones que experimentan son menores, reveló un estudio del Instituto Nacional de Psiquiatría Ramón de la Fuente.

El estudio arroja que en caso de soñar y experimentar emociones, estas suelen ser negativas, y el contenido de sus sueños suele ser menos detallado. “Además de soñar con menos frecuencia durante una noche, las pacientes deprimidas sueñan con mucho menos detalle, por ejemplo, sueñan una sola imagen, sin acción, sin historia”, dijo la investigadora Ana Paula Rivera García.

En el estudio participaron 12 pacientes con depresión y 12 mujeres sanas. A cada una se les convocó a dos noches de registro para que durmieran en el instituto. Fue en la segunda noche que se llevó a cabo el ensayo al interior de una cámara de sueño, para medir las expresiones del rostro durante el sueño y ser monitoreadas, a fin de detectar las fases de movimiento oculares rápidos, durante los cuales se llevan a cabo los sueños.

Se observó que entre las mujeres con depresión se incrementaba el voltaje del corrugador, músculo para fruncir el ceño, y se disminuía en el cigomático, el músculo de la sonrisa.

En entrevista con la Agencia Informativa Conacyt, la investigadora Rivera García subrayó que las personas sanas suelen experimentar historias cargadas de realismo y emociones durante el sueño. Este impedimento para soñar obedecería a un déficit en la comunicación entre las estructuras de la corteza frontal y regiones límbicas del hemisferio cerebral izquierdo. La conclusión es solo preliminar, por lo que se continuará investigando por qué las mujeres con depresión no consiguen consolidar sus sueños.

Una siguiente fase de la investigación será también aplicada a pacientes en remisión, así como en hombres y pacientes con ansiedad.

    I have noticed that over the course of creating a relationship with real estate managers, you’ll be able to come to understand that, in every real estate exchange, a payment is paid. All things considered, FSBO sellers will not “save” the percentage. Rather, they try to win the commission simply by doing an agent’s occupation. In the process, they invest their money in addition to time to conduct, as best they are able to, the assignments of an agent. Those duties include uncovering the home via marketing, representing the home to buyers, constructing a sense of buyer urgency in order to prompt an offer, preparing home inspections, controlling qualification inspections with the loan provider, supervising maintenance, and facilitating the closing of the deal.

    I have observed that in old digital cameras, exceptional devices help to concentrate automatically. The actual sensors associated with some digital cameras change in contrast, while others employ a beam with infra-red (IR) light, specifically in low lighting. Higher standards cameras often use a combination of both devices and might have Face Priority AF where the dslr camera can ‘See’ the face and focus only on that. Many thanks for sharing your thinking on this blog.

    Together with the whole thing that seems to be building within this subject material, a significant percentage of opinions are actually relatively radical. Having said that, I beg your pardon, because I can not give credence to your entire strategy, all be it refreshing none the less. It seems to me that your remarks are actually not totally rationalized and in reality you are generally your self not even entirely convinced of the argument. In any case I did enjoy examining it.

    Thanks for your write-up. I also believe laptop computers have grown to be more and more popular these days, and now are sometimes the only form of computer included in a household. The reason is that at the same time that they are becoming more and more affordable, their processing power keeps growing to the point where these are as strong as desktop computers coming from just a few years ago.

    What I have constantly told people today is that while looking for a good online electronics retail outlet, there are a few factors that you have to think about. First and foremost, you should really make sure to get a reputable and reliable retailer that has enjoyed great assessments and scores from other customers and marketplace analysts. This will ensure you are dealing with a well-known store that provides good assistance and assistance to its patrons. Thank you for sharing your thinking on this site.

    Thanks for the strategies presented. One thing I additionally believe is credit cards providing a 0 rate often bait consumers in zero rate, instant acceptance and easy internet balance transfers, but beware of the number one factor that will certainly void your 0 easy street annual percentage rate and also throw one out into the poor house quickly.

    I do like the manner in which you have presented this specific issue and it really does give me some fodder for consideration. Nonetheless, from what I have witnessed, I just simply hope as other commentary pile on that individuals keep on point and not get started on a soap box regarding the news of the day. All the same, thank you for this outstanding piece and whilst I do not go along with it in totality, I respect the standpoint.

    Yet another thing I would like to say is that rather than trying to fit all your online degree programs on days of the week that you end work (considering that people are exhausted when they come home), try to have most of your lessons on the weekends and only one or two courses on weekdays, even if it means taking some time off your weekend. This pays off because on the weekends, you will be extra rested in addition to concentrated upon school work. Thanks alot : ) for the different points I have discovered from your blog.
