Two top experts explain how the attention deficit brain works — and, in some cases, why it doesn’t always work at its best. DrThomasEBrown
There are two primary ways in which emotions play a critical role in the chronic difficulties of people with ADHD. Both are related to working memory impairments—the person’s limited capacity to keep in mind and use multiple bits of emotion-laden information at the same time.
At other times, the working memory impairments of ADHD leave the person with insufficient sensitivity to the importance of a particular emotion because he or she hasn’t kept other relevant information sufficiently in mind, or factored it into his or her assessment of the situation.Why doesn’t the ADHD brain always make the connection?
The networks that carry information related to emotion and other aspects of brain functioning tend to be somewhat more limited in individuals with ADHD compared to most others. Years ago, most scientists thought that impairments of ADHD were due primarily to problems within specific regions of the brain, particularly the prefrontal cortex.
Such abnormalities may explain some of the difficulties these individuals have — keeping one thing in mind while doing something else. One study has shown that methylphenidate, used to treat ADHD, can normalize the connectivity limitations in the motivation and reward networks of children with ADHD when they are performing some assigned tasks.
