There’s a common myth that most children or adolescents with attention deficit hyperactivity disorder grow out of the condition as they get older. This was based on various estimates suggesting that only between 10 and 50 percent of children with ADHD still have the disorder as adults.
A new University of Cambridge study, published in the journal European Child Adolescent Psychiatry, found that young adults who had ADHD when they were younger exhibited differences in brain structure and poorer memory performance compared to their peers who never had the disorder. Aspects of the disorder tended to persist into adulthood, even in those subjects who were not diagnosed as adults.
Nearly all showed brain volume reductions in the caudate nucleus, a brain region that is associated with the ability to integrate information from different parts of the brain, and is involved in the storing and processing of memories.
Dr. Graham Murray, a professor of psychiatry at Cambridge and the study’s lead author noted: “in the group with adolescent ADHD, this region of the brain is smaller and doesn’t seem to be able to respond to increasing memory demands.”
According to Dr. Harold Levinson, the results of this important study validates his own clinical findings reported over the past 4 decades in research papers and books, especially Total Concentration.
“Both dyslexia and ADHD do not disappear with age. The symptoms often change or are compensated for over time and training. But the underlying disorder or cause remains. Indeed, there are cases that intensify due to acquired impairments that magnify the underlying causation and/or diminish compensation”
The reason 100% of children with dyslexia and/or ADHD are not diagnosed as adults is simple, explains Levinson. “The diagnostic criteria are faulty and the disorders are poorly understood. For example, if only 10% of ADHD children are diagnosed as adults it means that that there is a 90% diagnostic error, not that the disorder disappears. “
“By simple analogy, if only 10% of childhood diabetics are diagnosed as adults, would anyone now conclude that childhood diabetes is outgrown? Since the insulin deficiency remains, all would now conclude that the diagnostic criteria were incorrect 90% of the time,” emphasizes Dr. Levinson.
