Selenium Level and Cognitive Function

[Ted Hutchinson]

Selenium Level and Cognitive Function in Rural Elderly Chinese. (http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=pubmed&cmd=Retrieve&dopt=AbstractPlus&list_uids=17272290&query_hl=22&itool=pubmed_docsum).......Lower selenium levels measured in nail samples were significantly associated with lower cognitive scores except the Animal Fluency Test . A dose-response effect of selenium quintiles was also seen for those significant associations. Results in this geographically stable cohort support the hypothesis that a lifelong low selenium level is associated with lower cognitive function.

This is good to know. I started taking selenium several years ago when I read a post by one with epilepsy. She took several minerals and vitamins to aid in seizure reduction. Some have had good results with that method. I added some to my diet as well. I haven't read the article yet to see the dose relationship to the results but would like to know more about this. I also want to know if there is an amount that is considered too much an the effects of taking too much. I am working with a population of persons with dementia and many with alzheimer's. Tattoo

This goes along with the oxidative component of neurological problems in general, and it goes with how selenium is added to vitamin E by some producers because selenium activates an antioxidant enzyme glutathione peroxidase.
