Children in households below the federal poverty level—an annual income of about $24,000 for a family of four—had gray matter volumes 7 percent to 10 percent lower than what would be expected for normal development. About 20 percent of American children lived at this income level in 2013, according to Census data. Smaller gaps were evident for households considered "near poor," making up to 150 percent of the poverty level, currently about $36,000 for a family of four.
Kids living just above the "near poor" level looked statistically similar to children from much wealthier families.
Obviously, 'being poor' is relative to those that are rich, so causation is a bit crusty. I don't know about the methods and how they relate to reality. This isn't telling us anything new but it does indicate a physiological issue. I'm not sure that tells us much that is new either.
Give it a read with your meter attached. Tell me what you think.
