A couple of interesting updates in the world of attention deficit disorder research. Of course, ADD is technically known by its formal medical name of attention deficit hyperactivity disorder, but people like to use both terms.
The first ADHD study comes from Spanish researchers who scanned the brains of 42 children with ADHD and 42 children without ADHD (the control group). Their results were that kids with ADHD had a smaller ventral striatum, particularly on the right side. If you are wondering, the ventral striatum includes the nucleus accumbens. That still isn’t helping, I’m sure. As it turns out the nucleus accumbens maintain a person’s level of motivation when they start a task and continues to maintain that motivation until the task is completed.
That seems to be a pretty precise understanding of brain function and anatomy, but if accurate, makes some sense. This study also gives additional weight to a hypothesis about the cause of ADHD and origin of ADD symptoms that says that attention deficit disorders are primarily caused by different brain structures or functions that impede the usual motivation and reward pathways.
This is obviously a very small study. No major conclusions can be drawn from the data presented as to ADHD’s cause or treatment of ADD symptoms. However, these small initial research studies like this one are an important step in both gaining enough scientific and medical credibility for the hypothesis that further research will be green-lighted by both government agencies and educational institutions and research facilities. They also play an important role in obtaining funding for larger research studies.
ADHD research like this recent study build the groundwork for the case that this isn’t just some wild guess about how ADD works and where ADHD comes from, but rather a sound hypothesis grounded in hard data that requires further testing. Put together with other ADD research recently that have come to similar preliminary conclusions, and this may just be the next major research path into the cause of ADHD in children and adults.
