School violence (which is becoming increasingly extreme), chronic stress, and excessive exposure to digital media (via mobile phones and tablets) are not isolated phenomena but rather reinforcing pressures that affect the developing brain of children and adolescents. This letter highlights the combined impact of school violence, stress, and screen exposure on neurodevelopment and adolescent mental health, and underscores the need for biomedical and educational interventions based on early preventive measures.

El Estrés Crónico, ¿Factor de Riesgo para la Enfermedad de Alzheimer?
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder, with epidemiological importance due to the high prevalence of people affected worldwide. Over time, various hypotheses have been raised in the pathophysiology and etiology of the disease and now the study of this disorder, is tackled from a multi-causal perspective, taking into account different etiological factors, among which are: genetics, oxidative stress, intracellular calcium dynamics, vascular effects, inflammation and stress, among others. The following literature review, aims to show studies that correlate stress as a risk factor in AD, recognizing the pathophysiological findings of AD, due to augmentation on glucocorticoids by chronic stress and the subsequent alteration of the hypothalamic-pituitary-adrenal axis. Critical view of these findings according to the literature.
