Brain Scans Show the Impact of Neglect On a Child's Brain Size

An anonymous reader writes "A shocking comparison of brain scans from two three-year-old children reveals new evidence of the remarkable impact a mother's love has on a child's brain development. The chilling images reveal that the left brain, which belongs to a normal 3-year-old, is significantly larger and contains fewer spots and dark 'fuzzy' areas than the right brain, which belongs to that of a 3-year-old who has suffered extreme neglect. Neurologists say that the latest images provide more evidence that the way children are treated in their early years is important not only for the child's emotional development, but also in determining the size of their brains. Experts say that the sizeable difference in the two brains is primarily caused by the difference in the way each child was treated by their mothers."

      No offense, AC, but your viewing "NUTRITION" and mothering as being two different things makes it obvious that you have never parented a young child.

      FYI, a newborn requires feeding every 3 hours, 24 hours a day, 7 days a week, for the first two months of their life. After about 8 or 9 weeks, if you are lucky, your child will (hopefully!) sleep for 5 to 6 hours at a time, so Mom can finally start getting more than 3 hours of sleep then. Furthermore, the experts also say that mom's breast milk is more nutritious than purchased formula and so a young child should be breast fed (by mom) for at least their first 6 months of life.

      The original research cites a large number studies with large numbers of children (hundreds or thousands). One of the major studies cited looks at different "types" of neglect which they call "global neglect" and "chaotic neglect". These mean multi-modal or single-modal sensory deprivation; e.g. no exposure to speech, or no exposure to physical experiences (for example, not allowed out of bed), no exposure to cognitive stimuli, etc.

      The research showed that for "chaotic neglect" (i.e. one aspect of stimulus missing), brain scans were usually normal, or only slightly abnormal (e.g. brain volume reduced). However, for "global neglect" (multiple aspects of stimulus missing), then nearly half the brain scans were abnormal, showing severely reduced brain volume.

      Of course, there are other aspects to neglect, not just sensory and intellectual deprivation; but that was not what the image, or the description in the text was about; this review purely (as far as possible in an observational study) looked at the differences between partial and severe sensory/intellectual deprivation.

I propose even if you gave the infant the correct nutrition while growing, withholding wider interaction with the world around them would have detrimental effect. When do you learn the most? As a child of course, from the day we are born our bodies systems begin a learning feedback loop. We lay the foundations of language in our minds. Our eyes learn to interpret the signals we receive. Our muscles begin to work in a coordinated manner. To pose this a different way, who would have better muscle tone? A. a person who eats cheetos and reads slashdot all day or, B. A person who works out three days a week a proper diet? Any rational person would answer B, because we need both good food and exercise to have a healthy body. Now take two people who eat healthy and work out, one lives in a calm stress free environment, the other in a high stress environment. Statistically, the person in a high stress environment will have a higher occurrence of disease. I would have to imagine that any environment where a child is neglected is going to cause stress on that child. From this (and some google-fu) we can posit these three things.

      A nutrition starved brain develops poorly.
      A neglected brain develops poorly.
      A stress flooded brain develops poorly.

      All three are very likely in a situation where a child would be neglected. We call it the maternal instinct (who knows if it is one in humans) to feed our children, to teach our children, and to soothe and calm our children. The parents with these traits are more likely to have sane children that will be around to spawn another generation.

      This doesn't apply only to babies and toddlers either. There was a study awhile back trying to figure out why certain groups of inner-city teens don't learn in school. As in, they were taught the same material, given the same homework, spent the same amount of time in class. The study controlled for things like truants and habitual trouble-makers. It turned out that all of them were dealing with at least major parental crisis. For example, their parents were severe alcoholics, beat them, sexually abused them, or died recently. When stuff like that happens, the kids' brains switched into survival mode and were then completely incapable of the kind of in-depth learning that normal kids enjoy. Remove the crisis, and the kid can learn at a normal capacity again. (Depending on the extent/length of the trauma.)

    Phrenology falls especially flat because it used skull morphology as an (inaccurate) proxy for measurements of the brain that weren't nondestructively available at the time(not that knowledge of brain function was good enough to have made such measurements useful even if available); but it was an early stab at the theory that psychological phenomena, and 'mind' in general, are ultimately dependent on the physical operations of the brain.

    That's the nuisance. Phrenology was embarrassingly lousy as an actual scientific theory of anything resembling predictive power(and pop-phrenology was even worse, barely better than horoscopes and speculations about why undesireables look like monkeys); but made an early grab for the only really viable premise in neurology, the idea that mental phenomena are ultimately based on physical activity in the brain.

Of course during most of the last 6000 years (where we actually have a historical record) the mean life expectancy was less than 20, women were de facto chattel and slaves, crime was no less commonplace than it is today (for all that it was punished far more severely), humanity was trapped in a state of unbelievable ignorance concerning the natural state of affairs that led them to adopt the most extravagant and absurd mythologies and use them to transform the status quo into "the will of the gods", and life was sufficiently close to the state of nature that it was ugly, nasty, brutish and very, very short even in what laughingly passed for "civilization". No noble savages these, but men and women for whom violence and misery were the normal state of affairs.

    The poorest and meanest individuals living in modern society live better than the rulers of vast empires lived a mere century or two ago.

    And then there is war. And the fact that what you call "sexual liberation" has never been anything but the rule for the lusty old human species, however much some of those antique and false mythologies sought to demonize it and regulate it. That, in fact, is why sex "worked" to perpetuate the species. Evolution requires warm bodies, produced in abundance, and lets abilities and luck sort it all out afterwards.

    Personally, I think that while TFA is undoubtedly correct that it is really gangbusters good to love your children and provide them with a stimulating environment and the occasional kick in the pants to overcome the natural sloth to which our species (with its energy conserving reptile-brain core) is prone, "sexual liberation" has far less to do with any sort of social ennui or malaise visible among youth than the fact that our society forces them to delay acceptance into society as adults until they are in their 20s, when their evolved biology presumes that they would be 50% likely to be dead by their 20s and that "adulthood" begins at age 13 or thereabouts.

    There is a deadly window in the teenage years where every hormone flooding a young brain is whispering to them to have sex, start a family, challenge the tribal leaders for status, run away to found your own tribe. It stimulates risk taking (which fuels evolution, successful risk takers being good genetic stock). It is the occult cause of gangs (tribes where youth can gain status), teen-age pregnancy, overt and covert rebellion against parents, society, experimentation with drugs and alcohol, tattoos and piercings. Failure to attain social status during these years is deadly indeed -- it is often the kids that are "outsiders", who don't fit in, who become depressed, although mere brain dysfunction due to imbalances of various neurotransmitters or damage from the toxins rampant in modern civilization no doubt contribute more than their fair share. One of the largest causes of death at this age is the humble automobile -- we let children in the throes of this transition drive massive machines at high speeds largely because it is more convenient to the adults to permit them to do so, and pay the price in human misery when they not terribly surprisingly run their cars into trees, into other cars, into ditches and rivers as they drive them too fast, without enough fear of consequence or attention, with other equally distracted youth in the car with them egging them on in pushing the envelope.

    For all that -- your "rampant suicide, depression, crime and delinquency" -- youth outlive their predecessors from more than 50 years ago by an increasing margin, and one that is clearly correlated with both reproductive age/female fertility (negatively) and education (positively) across many countries and social strata.
