Confirmation of the neurobiological origin of ADD

[ScottMentalPod]

One step closer to quickly and easily determining if someone really has ADD.

"A study, carried out on mice, has just confirmed the neurobiological origin of attention-deficit disorder (ADD), a syndrome whose causes are poorly understood. Researchers from CNRS, the University of Strasbourg and INSERM1 have identified a cerebral structure, the superior colliculus, where hyperstimulation causes behavior modifications similar to those of some patients who suffer from ADD. Their work also shows noradrenaline accumulation in the affected area, shedding light on this chemical mediator having a role in attention disorders. These results are published in the journal Brain Structure and Function."

Does every case of ADHD have to have the same neurobiological origin? I mean taking the definition from the DSM it's a behavioral model, which doesn't necessarily correspond to a specific neurobiological process a priori.

However, finding biological instantiations may allow for much more effective help for a particular case of ADHD.

If you think about genus/species relationships in biology, especially those before we had an understanding of evolution, sometimes the related animals are not as related as we thought. It will be interesting to see where our continually expanding knowledge in the field of neurobiology takes us.
