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.
