Here's what the article says: "According to the study, people who said they were a "born-again" Protestant or Catholic, or conversely, those who had no religious affiliation, had more hippocampal shrinkage (or "atrophy") compared to people who identified themselves as Protestants, but not born-again."
Almost universally, people posting responses jumped on the "Christians are brain-damaged morons" bandwagon. But who has hippocampal shrinkage - in addition to those who say they're born again? According to the article, "those who had no religious affiliation".
It looks like atheists and agnostics do-gooders who want to save Christians from certain brain atrophy will never succeed because they themselves have brain atrophy to worry about.
Before ranting about someone else's supposed brain atrophy, cure your own.
