Does poor motivation or ‘bad parenting’ cause ADHD? Studies say it’s in the brain structure

|

For the first time, scientists can point to substantial empirical evidence that people with attention-deficit/hyperactivity disorder have brain structures that differ from those of people without ADHD. The common disorder, they conclude, should be considered a problem of delayed brain maturation and not, as it is often portrayed, a problem of motivation or parenting.

In conducting the largest brain imaging study of its kind, an international team of researchers found that ADHD involves decreased volume in key brain regions, in particular the amygdala, which is responsible for regulating the emotions. Although the study…included children, adolescents and adults, the scientists said the greatest differences in brain volume appeared in the brains of children.

“I think most scientists in the field already know that the brains of people with ADHD show differences, but I now hope to have shown convincing evidence…that will reach the general public and show that it has [a basis in the brain] just like other psychiatric disorders. … We know that ADHD deals with stigma, but we also know that increasing knowledge will reduce stigma,” said geneticist Martine Hoogman of Radboud University in the Netherlands.

    This does not explain why the vast majority of cases involves boys.

    Not surprising that Genetic Lunacy Project also thinks brain imaging is a valid science. It has been called voodoo and the new phrenology by intelligent people. Here is just one example, there are many more.

      The article you linked to only discusses fMRIs. It says nothing bad about MRIs, which, if you looked at the study, is what they used.

      • Naj Nakajim

        A functional MRI is supposed to be an improvement in Magnetic Resonance Imaging so I’m not sure what your point is.

        • Chloe

          But this article nor the study are about the uses of the fMRI. It’s entirely possible that the fMRI was developed as an improvement of the MRI but failed to be an improvement. That doesn’t meant that the MRI itself isn’t valid, so I’m not sure what YOUR point is. Link an article that shows that MRIs themselves are voodoo science, and then we can talk about the validity of this study, but if all you have is stuff on fMRIs, your point is invalid.
