Preventing Alzheimer's disease (AD) would require knowledge about its etiology to a degree of detail not yet available. The major hurdle in understanding the disease lies in teasing out the various causes and their complex interactions. Since considerable data have accrued showing that the essential trace element selenium (Se) might play different roles in the progression of AD, we conducted a systematic review of the literature regarding Se and AD. We identified 9 placebo-controlled studies (6… 
Brain Selenium in Alzheimer’s Disease (BRAIN SEAD Study): a Systematic Review and Meta-Analysis
This meta-analysis provides consolidated evidence for a significant decrease of selenium status in AD brains compared to controls, and supports new therapeutic strategies aimed at brain tissue Selenium homeostasis in AD.
Zinc diet and Alzheimer's disease: a systematic review
Neither randomized-controlled trials nor observational studies provide conclusive evidence whether Zn in the diet is associated with cognitive decline or AD, and the current state of evidence does not allow conclusions to be drawn on whether supplementation of Zn is beneficial for the prevention or treatment of AD.

Treatment strategies in Alzheimer’s disease: a review with focus on selenium supplementation
The role of Se in AD treatment is discussed and strategies for AD prevention by optimizing selenium intake are suggested, in accordance with the metal dysregulation hypothesis, including in particular secondary prevention by seenium supplementation to elderly with mild cognitive impairment.
Selenium and cognitive impairment: A brief‐review based on results from the EVA study
Results obtained in the frame of a longitudinal study on Se and cognitive impairment are consistent with the hypothesis that low Se status is a risk factor for cognitive decline even after taking into account vascular risk factors.
Selenoprotein P and its potential role in Alzheimer’s disease
Recent findings on the possible role of SELENOP in AD are summarized, with a focus on probable mechanisms: Se delivery to neurons, antioxidant activity, cytoskeleton assembly, interaction with redox-active metals, and misfolded proteins (amyloid beta and tau protein).
A selenium species in cerebrospinal fluid predicts conversion to Alzheimer’s dementia in persons with mild cognitive impairment
Results indicate that higher amounts of a potentially toxic inorganic selenium form in cerebrospinal fluid may predict conversion from mild cognitive impairment to Alzheimer’s dementia.
New Perspectives on Alzheimer's Disease and Nutrition.
There is consensus among the authors that nutritional deficits, and even states of excess, are associated with AD, but more work is needed to determine cause and effect.
A systematic review and meta-analysis of the circulatory, erythrocellular and CSF selenium levels in Alzheimer's disease: A metal meta-analysis (AMMA study-I).


Nutritional status of selenium in Alzheimer's disease patients
It is suggested that AD has an important relation with Se deficiency, as AD patients showed significantly lower Se levels in plasma, erythrocytes and nails when compared with the control group.
Does inorganic mercury play a role in Alzheimer's disease? A systematic review and an integrated molecular mechanism.
In vitro models showed that inorganic mercury reproduces all pathological changes seen in AD, and in animal models in organic mercury produced changes that are similar to those seen inAD, and a mechanistic model describes potential causal pathways.
Aluminum in the diet and Alzheimer's disease: from current epidemiology to possible disease-modifying treatment.
Future studies need to be more rigorous to truly test the validity of previous findings and attempt to identify dose-response relationships between Al and AD risk which may provide new routes to disease-modifying treatment of AD or possibly some lifestyle modification, to supplement existing symptomatic approaches.
Antioxidant strategies for Alzheimer's disease
Treatment with antioxidants is a promising approach for slowing disease progression to the extent that oxidative damage may be responsible for the cognitive and functional decline observed in AD.
Is antioxidant use protective of cognitive function in the community-dwelling elderly?
Elevated glutathione as a therapeutic strategy in Alzheimer's disease
This work suggests that the body's own endogenous antioxidant systems should be mobilized against the oxidative stress inherent in AD brain, and suggests ways to increase glutathione levels.
Trace elements and cognitive impairment: an elderly cohort study.
Association of antioxidants with memory in a multiethnic elderly sample using the Third National Health and Nutrition Examination Survey.
Serum levels of vitamins A and C, beta-carotene, and selenium were not associated with poor memory performance in this study, and vitamin E per unit of cholesterol was consistently associated with increasing levels of poor memory after adjustment for age, education, income, vascular risk factors, and other trace elements and minerals.
