This was one of the first meta-analyses of neuropsychological results for adults with ADHD. The study provides a succinct and useful summary of these neuropsychological results of over 25 studies.

It summarizes an existing body of research. It is useful to others because the primary results of these pre-existing studies are summarized.

The paper primarily found that adults with ADHD have deficits in several areas of brain functioning. These deficits are similar to areas that have been found to be abnormal among children and adolescents.

This speaks to the developmental consistency of ADHD as a diagnosis and suggests that the brain dysfunction that underlies the manifestation of ADHD-like behaviors is similar across development.

This developmental consistency in neuropsychological dysfunction, along with other studies reports of developmental consistency in treatment response, symptom presentation, impairment, etc., provides further evidence of the validity of this disorder among adults.

I became involved in this research primarily out of an interest in learning more about the underlying brain dysfunction that might cause ADHD behaviors.

Neuropsychological tasks are an effective method for measuring brain function and determining what areas of the brain might be dysfunctional.

I noticed that the number of studies examining neuropsychological functioning in adults with ADHD was quite minimal. I therefore began implementing those neuropsychological paradigms that were shown to be abnormal among children with ADHD in adults with ADHD.
