It is critical to maintain proper nutrition in order to keep the body robust and healthy. Poor nutrition can exacerbate behavioral symptoms and lead to weight loss in people with Alzheimer's or dementia. Loss of appetite and weight loss may become issues as the condition advances. In such circumstances, the doctor may recommend calorie-dense supplements to be taken in between meals. There is mounting evidence that antioxidant elements, fish, dietary fats, and B-vitamins, among other foods, may play a role in the development of Alzheimer's disease and cognitive decline with age. Antioxidant nutrients have been established in numerous animal and laboratory studies to protect the brain from oxidative and inflammatory damage.
