I am a geriatrician and wondered if the effect of food additives has been studied on Alzheimers patients, due to a porous blood-brain barrier – from the 2012 roadshow
(Comment by Sue Dengate: Interesting question! See our factsheet http://fedup.com.au/factsheets/symptom-factsheets/food-additives-and-dementia-and-other-food-intolerance-symptoms-in-the-elderly. There is evidence that food additives actually alter blood-brain barrier permeability: Nemeroff CB, Crisley FD. Monosodium L-glutamate-induced convulsions: temporary alteration in blood-brain barrier permeability to plasma proteins. Environ Physiol Biochem. 1975.http://www.ncbi.nlm.nih.gov/pubmed/1213027 )
