Resumen
La enfermedad del Alzheimer es una patología neurodegenerativa compleja que involucra mecanismos moleculares, celulares y genéticos. Entre sus principales manifestaciones se encuentran la acumulación de placas beta amiloides, la formación de ovillos neurofibrilares debido a la hiperfosforilación de las proteínas Tau, y una respuesta inflamatoria exacerbada causada por la activación de la microglía y astrocitos mediada por citocinas. Estos procesos están estrechamente ligados con variantes genéticas clave como APOE, APP, TREM2, PSEN1, PSEN2, BIN1 y SORL1, que contribuyen significativamente en el desarrollo de la enfermedad. Los tratamientos actuales, como los fármacos aprobados por la FDA, se centran en ralentizar su progresión y las investigaciones más recientes se dirigen hacia la exploración de enfoques integrativos, estos incluyen el uso de antioxidantes, simbióticos y modificaciones dietéticas como estrategias preventivas y adyuvantes terapéuticos. Una compresión más profunda de estos mecanismos y tratamientos emergentes es esencial para afrontar este importante desafío de salud global.
Alzheimer's disease is a complex neurodegenerative pathology involving molecular, cellular, and genetic mechanisms.Its main manifestations include the accumulation of beta-amyloid plaques, the formation of neurofibrillary tangles due to the hyperphosphorylation of Tau proteins, and an exacerbated inflammatory response caused by the activation of microglia and astrocytes mediated by cytokines. These processes are closely linked to key genetic variants such as APOE, APP, TREM2, PSEN1, PSEN2, BIN1, and SORL1, which significantly contribute to the development of the disease. Current treatments, such as FDA-approved drugs, focus on slowing its progression and recent research is directed toward exploring integrative approaches, these include the use of antioxidants, symbiotics, and dietary modifications as preventive strategies and therapeutic adjuvants. A deeper understanding of these mechanisms and emerging treatments is essential to address this significant global health challenge.
