I read this article a few mornings ago. Warning: it is only an abstract.
Among the pathogens contributing to this burden: Helicobacter pylori
, herpes simplex 1 & 2, cytomegalovirus and Chlamydia pneumoniae
were linked with statistically significant affect in executive function and language skills (i.e., memory, attention, decision making, communication, etc.)
Apropos of nothing: I remember reading about history of eradication of H. pylori being associated with Alzheimer's disease-drug usage later on in life by Chinese researchers in 2013 from PUBMED. Some AD drugs, e.g., can be used in mild cognitive dementia, like donepezil. The work kind of reminded me of Norgaard et al. and prescription antibiotic redemption in MS.
Hope you're all well in 2014.
