Emotional dysregulation may be the most troubling behavior presenting with school problems. Is it possible we're seeing much more of it in school aged children? - the answer is definitely yes. The causes are multifactorial - mild birth injury, prematurity, autism spectrum disorders, psychiatric or psychological disorders (explosive or 'bipolar' child) and others, and schools have had to adjust by adding behavioral specialists and adjusting classroom environments at school.
Having a visual fMRI paradigm like this to assess and quantitate emotional regulation will be important for designing more specific interventions in the future.
