Diet And Exercise

With the world’s population aging at a rapid rate, the prevalence of Alzheimer’s disease (AD) has significantly increased. These statistics are alarming given recent evidence that a third of dementia cases may be preventable. The role of lifestyle factors, such as diet and exercise, can directly alter the risk of disease development. However, an understanding of the effectiveness of dietary patterns and exercise strategies to reduce AD risk or improve brain function is not fully understood. The aim of this review is to discuss the effects of diet and exercise on AD risk. Key components of the Western and Mediterranean diets are discussed in relation to AD progression, as well as how physical activity promotes brain health. Components of the Western diet (saturated fatty acids and simple carbohydrates) are detrimental to the brain, impair cognition, and increase AD pathologies. While components of the Mediterranean diet (polyunsaturated fatty acids, polyphenols, and antioxidants) are considered to be neuroprotective. Exercise can significantly reduce the risk of AD; however, specific exercise recommendations for older adults are limited and optimal intensity, duration, and type remains unknown. This review highlights important modifiable risk factors for AD and points out potential avenues for future research. Novelty Diet and exercise are modifiable factors that can improve brain health and reduce the risk of AD. Polyunsaturated fatty acids, polyphenols, and antioxidants are neuroprotective. Exercise reduces neuroinflammation, improves brain insulin sensitivity, and increases brain derived neurotrophic factor.

The objective of this study was to conduct a review about the nutritional aspects and their influences on the pathophysiology of Alzheimer’s disease. The review describes the pathophysiology of Alzheimer’s disease, the generally indicated diets, and the nutritional factors that may aggravate the disease based on a literature review using the following keywords in English and Portuguese: “Alzheimer’s disease”, “physiopathology”, “nutritional aspects”, and “antioxidants”. A total of 100 articles were found, 48 in Lilacs and 52 in MedLine, but only 54 articles were selected for the review. The use of antioxidants as free radical scavengers is generally indicated in diets for Alzheimer’s patients. Studies also suggest that caffeine, vitamin B12, and folic acid have neuroprotective effects. Cohort studies found that a high intake of saturated fatty acids and obesity increase the risk of Alzheimer’s disease. People with Alzheimer’s disease should avoid diets high in carbohydrates and saturated fats, and prefer foods high in antioxidants.Keywords: Alzheimer disease; Antioxidants; Neurophysiology; Review literture as topic.

The aging population is a significant social, medical and economic problem due to increasing prevalence of chronic diseases in elderly population. Alzheimer's disease (AD) is the most common form of dementia and the most common neurodegenerative disease. It is characterized by a progressive deterioration of memory and cognitive function. So far, there is neither an effective prevention nor cure for dementia, so more and more attention is paid to the prevention of this group of diseases, particularly to the appropriate diet. Preventive intervention gives the best results if introduced before the first symptoms of dementia, i.e., around the age of 50. This is when the nutritional status, number of synapses, cognition, and neuropathological changes in the nervous system compensate each other, which increases the chances of staying healthy for a longer period of time. It has been proven that dietary habits, which lead to the development of cardiovascular and metabolic diseases, significantly increase the risk of dementia. On the other hand, a Mediterranean diet rich in antioxidants, fiber and omega-3 polyunsaturated fatty acids may have a protective effect on the neurodegenerative process. The beneficial effect of many nutrients on the course of AD has been demonstrated. These include: glutathione, polyphenols, curcumin, coenzyme Q10, vitamins B6, B12, folic acid, unsaturated fatty acids, lecithin, UA, caffeine and some probiotic bacteria. A diet rich in saturated fatty acids and branched-chain amino acids (BCAA) promotes the progression of dementia. Dietary intervention should be introduced as early as possible to minimize the risk of developing dementia. The Mediterranean and DASH diets have been documented to protect against AD. However, the MIND diet is reported to be much more effective in preventing cognitive decline/dementia than either the Mediterranean or DASH diets alone.

Pufa Supplementation

Significant research attention has focussed on the identification of nutraceutical agents for the prevention of cognitive decline as a natural means of cognitive preservation in the elderly. There is some evidence for a reduction of brain omega 3 polyunsaturated fatty acids (n-3 PUFAs) in normal aging and in Alzheimer’s disease. n-3 PUFAs exhibit anti-inflammatory and anti-amyloidogenic properties as well as being able to reduce tau phosphorylation. Many observational studies have demonstrated a link between n-3 PUFAs and cognitive aging, and some, but not all, randomized controlled trials have demonstrated a benefit of n-3 PUFA supplementation on cognition, particularly in those subjects with mild cognitive impairment. The identification of a biomarker that reflects n-3 PUFA intake over time and consequent tissue levels is required. In this narrative review we discuss the evidence associating red blood cell membrane n-3 PUFAs with cognitive function and structural brain changes associated with Alzheimer’s disease.

Acetylcholine deficiency is a neurochemical characteristic of patients with clinical diagnosis of Alzheimer´s disease. Substances that inhibit the enzyme acetylcholinesterase, increasing levels of acetylcholine in the brain, are a promising form of treatment. Studies relate the use of omega-3 fatty acids in the treatment and prevention of Alzheimer's disease. The Northeast Region of Brazil has an enormous biological diversity and a wide variety of fish species. In this work, the oils of eleven species of marine fish found on the coast of Ceará, Brazil, were analyzed in relation to the fatty acid profile and the inhibitory activity of the enzyme acetylcholinesterase. Total lipids were extracted from fish samples by Folch metodology. The lipid extracts of the fish and industrialized fish oil, used for comparison, were esterified and fatty acid profiles were analyzed. The acetylcholinesterase inhibitory activity was measured quantitatively. The oils presented a high percentage of saturated fatty acids, which is a general characteristic of tropical fish. Oleic acid was the highest monounsaturated fatty acid. Oils of Scomberomorus cavalla, Lutjanus synagris and Haemulon plumieri presented expressive percentages of polyunsaturated fatty acids and the most potent anticholinesterase activities. This research showed the oils of S. cavalla, L. synagris and H. plumieri may be promising functional food products of active fatty acids as new therapies to treatment or prevention of Alzheimer's disease. The expressive concentration of unsaturated and polyunsaturated fatty acids together with their relevant anticholinesterase activity are characteristics of the importance of these fish oils.
