Finding different intervention methods to treat these conditions is a public health challenge. Thus, exploring the results obtained by transcranial magnetic stimulation (TMS) is critical since this neurostimulation technique could position itself as a blunt alternative to manage anxiety pathologies. In this review, a systematic search for TMS use in anxiety disorders was carried out based on the PRISMA criteria. It was found that the most effective protocol for TMS treatment for anxiety disorders is performed with low-frequency stimulation (1 Hz), with 110% of the motor threshold. Furthermore, repeated TMS has proven its effectiveness in different psychiatric disorders — not only as a therapeutic alternative but also in the search for neurolo-gical biomarkers—. TMS favors neuromodulation through the generation of action potentials, which facilitates the treatment of pathologies related to emotional components, such as anxiety. However, further research is needed to specify the neurobiological mechanisms present in the improvement of symptoms.","PeriodicalId":53921,"journal":{"name":"Revista Mexicana de Neurociencia","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2021-12-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45263694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

People in AIDS phase with CD4 count under 250, may be at greater risk of suffering from depression. Objective: Eva-luate whether there is a relationship between T-CD4 lymphocyte count and depression in people living with HIV but have not started antiretroviral treatment. Method: This was a cross-sectional cohort study conducted between October 2020 and January 2021 in the HIV Unit of the Eugenio Espejo Hospital in Quito. A CD4 test was performed, and the Hamilton Depression Scale was used in patients after 1 month of being diagnosed with HIV but before receiving antiretroviral treatment. Results: A total of 108 subjects were recruited, mainly men (79.6%), of which 82.4% were between 18 and 45 years old. The subjects in the AIDS phase were 25% of which 92.6% presented depression (p = 0.000), it was noted that the older the age, the prevalence of depression increases (p = 0.007). As for the female sex, it seems to have a risk of practically double with respect to men of suffering from depression (p = 0.005). Conclusions: In our cohort study, at PLWH in Ecuador, patients in AIDS phase present a considerable risk of suffering from depression; at the same time, as the age increases, the probability of presenting depression is greater. As well as, female sex is a risk factor. Therefore, the follow-up of these patients is an essential part of care and treatment process.","PeriodicalId":53921,"journal":{"name":"Revista Mexicana de Neurociencia","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2021-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45557725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data from the scientific literature suggest the existence of a promising therapeutic potential in neurology and psychophysiology due to their influence on specific frequencies of brain waves and their implications for mental health and homeostasis of brain neurotransmitters. Prolonged audio stimuli in repetitive and synchronized manner may induce changes in brain waves patterns and, consequently, modulating neurophysiological, and behavioral responses. The literature review was conducted using PUBMED, MEDLINE, LILLACS, and SCIENCE DIRECT online platforms using the search words: “audio brain entrainment,” “auditory beat stimulation, ” “binaural beats,” “brainwave entrainment (BWE),” and “isochronic tones.” The search yielded 674 studies, of which 49 were in duplicate, and 592 were out of the scope of this review, and, therefore, were excluded from the study. The remaining studies were analyzed according to the Cochrane Handbook for Systematic Reviews, resulting in 33 randomized, controlled clinical trials that were then evaluated by the Jadad scale. From that, 17 studies obtained a score of three points or more on the Jadad scale. These studies were fully read and critically analyzed. Binaural beats were used in 15 studies (88.25%), whereas isochronic tones were used only in two studies (11.76%). Although most of the studies reviewed here indicated audio BWE effectiveness, some positive outcomes may require further investigation, with more refined and appropriate evaluation tools, better suited for each specific type of intervention and/or therapeutic target. Considering these limitations, the performance of additional studies with more adequate experimental design and data analysis is recommended, particularly focusing on the neurophysiological and behavioral effects of brain wave entrainment on mental states.","PeriodicalId":53921,"journal":{"name":"Revista Mexicana de Neurociencia","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2021-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42873856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There seems to be different environmental insults that may act as triggers in genetically predisposed subjects; these insults can promote an inflammatory response in which interleukin-6 could participate actively at the level of neural stem cells and progenitors. The degree of involvement in neurogenesis and astrogenesis, and therefore, the observed clinical spectrum will depend on two facts that alter the neural circuits, including the brain region that loses proper input or output connectivity due to abnormal migration of a group of neurons, and the astrocytic survival.","PeriodicalId":53921,"journal":{"name":"Revista Mexicana de Neurociencia","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2021-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48295359","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present review evaluates the information acquired from primary and secondary sources, focusing on the alterations in gene expression associated with AD as well as the alterations in gene expression associated with DM, to later highlight the influence that these types of alterations developed in patients with DM can have on both the development and progression of AD. Finally, we point out those alterations that impact the phospha-tidyl Inositol 3 Kinase/Akt (PI3K/Akt) pathway, which seems to intervene in the physiopathological process of both diseases, considering that the compression of these gene alterations can help us understand the intricate link between DM and AD.","PeriodicalId":53921,"journal":{"name":"Revista Mexicana de Neurociencia","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2021-10-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47379442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
