ABSTRACT

Introducción: la enfermedad de Alzheimer es la forma más común de demencia, la cual se asocia con el deterioro pro-gresivo de las funciones cognitivas; se caracteriza por la for-mación de ovillos neurofibrilares y placas seniles conformadas por la sustancia ß-amiloide. Desarrollo: el eje microbiota-intestino-cerebro permite la co-municación entre el tracto gastrointestinal y el cerebro. La micro-biota intestinal sufre modificaciones por el envejecimiento como el incremento de la permeabilidad intestinal y la translocación bacteriana. En presencia de disbiosis, los cambios en la motilidad y la secreción gastrointestinal alteran las células neuroendocrinas y del sistema inmune, y afectan la liberación de neurotransmiso-res. Así, las modificaciones de la microbiota pueden ocasionar la neuroinflamación que se observa en la enfermedad de Alzhei-mer. Los productos prebióticos y cepas de probióticos demostra-ron ser beneficiosos a nivel neurológico en dicha enfermedad, detectándose expresión de neurotransmisores y mejoría en las funciones cognitivas. Conclusiones: se ha documentado el uso de prebióticos y pro-bióticos en la enfermedad de Alzheimer, y se refirió que ocasio-nan reducción de la inflamación intestinal y disbiosis, así como mejora de las funciones cognitivas en estos pacientes. Sin em-bargo, en el tratamiento de la enfermedad de Alzheimer aún no se contempla el uso de los probióticos y tampoco se ha consi-derado como manera preventiva dado que las investigaciones son recientes.

ABSTRACT

Alzheimer's disease corresponds to 50­70% of all dementia syndromes, classified as a progressive neurodegenerative disease showing diffuse cortical atrophy with three stages of evolution: mild, moderate, and severe. Behavioral symptoms and memory loss are major manifestations of the disease. Non-pharmacological interventions are essential to improve the quality of life of these patients. Interdisciplinary assistance is essential throughout the disease course. Regarding nutrition for patients with Alzheimer's disease, weight loss and behavioral changes related to food are major objects of scientific study, as they trigger deterioration of the quality of life of patients and caregivers. Knowing which nutritional guidelines should be used helps in clinical decisions. The study of nutrition in dementia is, therefore, critical for patient management.

ABSTRACT

Type 2 diabetes and obesity are possible risk factors for Alzheimer’s disease and these can be modified by physical activity and changes in dietary patterns, such as switching to a Mediterranean diet. This diet includes fruits, vegetables, olive oil, fish and moderate wine intake. These foods provide vitamins, polyphenols and unsaturated fatty acids. This diet should be able to reduce oxidative stress. The inflammatory response is also reduced by unsaturated fatty acids, resulting in a lower expression and a lower production of pro-inflammatory cytokines. The Cardiovascular protection is related to the actions of polyphenols and unsaturated fatty acids on the vascular endothelium. The Mediterranean diet also can improve cardiovascular risk factors such as dyslipidemia, hypertension and metabolic syndrome. These beneficial effects of the Mediterranean diet should have a role in Alzheimer’s disease prevention.
