Vitamin C protects against Alzheimer´s disease

Summary The progression of Alzheimer’s disease is linked to two factors: the breakdown of the blood-brain barrier (highly selective barrier that separates blood from the brain) and the dysfunction of mitochondria (organelles placed in the cells that are involved in energy production). Vitamin C has been reported to function as a modulator of blood-brain barrier…

Vitamin E inhibits Alzheimer’s progression

Summary This study determined if vitamin E, the drug memantine, or a combination of both slow the progression of Alzheimer´s disease. 613 patients affected by Alzheimer´s disease received either vitamin E, memantine, vitamin E and memantine combined, or a placebo. It was discovered that vitamin E administration led to a slower progression of the disease.…

Flavonoids are effective protective agents against Alzheimer’s disease

Summary The brains of patients with Alzheimer’s disease have an abundance of amyloid plaques, made up of protein fragments. The excessive accumulation of these proteins is believed to be a key mechanism responsible for brain cell death in Alzheimer’s disease. The present study aimed to identify flavonoids (naturally occurring compounds) that could inhibit amyloid plaques-induced…

Micronutrient supplement improves brain function

Summary The present study examined the effect of a micronutrient combination on brain function. The supplement consisted of curcumin, piperine, epigallocatechin gallate, α-lipoic acid, N-acetylcysteine, B vitamins, vitamin C and folate and was administered for 6 months to mice affected by Alzheimer´s disease. The results of this examination revealed that the micronutrient combination improved brain…

Omega-3 fatty acids reduce inflammation in Alzheimer’s disease

Summary Neuroinflammation, an inflammation of the nervous system, is a characteristic of a multitude of nervous system disorders. This review summarized 61 studies that tested the effect of omega-3 on neuroinflammation in various diseases, including Alzheimer’s disease. The results showed that omega-3 fatty acids have anti-inflammatory properties and can fight neuroinflammation in this brain disease.…

Healthy diets can protect against Alzheimer´s disease

Summary This study evaluated the relationship between diet and Alzheimer’s disease in normal individuals at risk for this disease. Data from 52 people were analyzed. The association between nutrients and brain function was assessed by means of a questionnaire. The researchers found that higher intakes of fresh fruit and vegetables, whole grains, fish and low-fat…

Omega-3 fatty acids prevent mental decline

Summary Alzheimer’s disease is the leading cause of dementia and the most common neurodegenerative disease in the elderly. This review analyzed epidemiological, dietary intervention and supplementation studies on Alzheimer’s disease. According to the review, the studies supported the role of omega-3 fatty acids in the prevention or delay of mental decline (reduction of brain function)…

Low blood levels of vitamins and carotenoids are related to Alzheimer’s disease

Summary This study investigated blood levels of vitamins and carotenoids in Alzheimer’s patients. Data from patients with Alzheimer’s disease were compared with data from participants without the disease. The results showed that Alzheimer’s patients had significantly lower levels of vitamin A, vitamin E and beta-carotene. In view of this result, the present study is a…

Vitamin B prevents decline in mental ability

Summary This study evaluated the effects of vitamin B supplementation on dementia, which is a broad category of brain diseases that cause a decline in mental ability. Data from elderly people were analyzed, revealing that B-vitamin supplementation can slow the shrinking of brain regions that are affected by Alzheimer’s disease and that are associated with…

Vitamin B1 improves mental function

Summary This study evaluated the effects of thiamine (vitamin B1) in patients with Alzheimer’s disease. Patients received either vitamin B1 or an ineffective placebo for 3 months. 11 participants completed the study. The results demonstrated that vitamin B1 supplementation improved the mental function of Alzheimer’s patients, as compared to those taking a placebo. More details…

Vitamin D insufficiency and deficiency are associated with Alzheimer´s disease

Summary This study evaluated the relationship between blood levels of vitamin D and Alzheimer´s disease. Data were collected from 318 participants. The results showed that vitamin D insufficiency and deficiency were associated with Alzheimer´s disease. Further details can be found in the study. References J S Buell, B Dawson-Hughes, T M Scott, D E Weiner, G E Dallal, W Q…

Pycnogenol improves memory function

Summary This study examined the effects of the natural compound pycnogenol (pine bark extract) in healthy people. For 3 months, 101 elderly participants were given a daily dose of 150 mg of pycnogenol. At the beginning, during and end of the treatment, the participants completed different mental tasks, comprising memory tests and other measures. The…

B vitamins slow mental decline

Summary Homocysteine, an amino acid found in the blood, represents a risk factor for Alzheimer’s disease. This study evaluated the relationship among homocysteine, Alzheimer’s disease and levels of B vitamins in the blood. 266 participants with cognitive (mental) impairment were given either folic acid, vitamin B12 and vitamin B6 or a placebo for 2 years.…

Omega-3 fatty acid DHA preserves brain function

Summary This review collected scientific studies on the effects of the omega-3 fatty acid docosahexaenoic acid (DHA) on brain function. A large number of studies has reported beneficial effects of dietary DHA supplementations on memory and cognition. In this publication, the authors described the important potential of DHA to preserve neuronal and brain functions. They…

Vitamin E reduces risk of Alzheimer’s disease

Summary This study investigated the association between blood levels of vitamin E and the occurrence of Alzheimer’s disease among older individuals. 232 people without dementia were followed-up to 6 years to detect signs of Alzheimer’s disease. The investigation revealed that high blood levels of vitamin E were associated with a reduced risk of Alzheimer’s disease…

Vitamin D prevents Alzheimer’s disease

Summary This study determined the relationship between dietary intake of vitamin D and dementia. 498 women without dementia, Alzheimer’s disease or other dementias were included.
