Scientists from the US was investigated by magnetic resonance imaging of the brain structure of children suffering from attention deficit disorder with hyperactivity. Doctors have found that some brain centers such children are different disabilities, which is not observed in healthy children.
As demonstrated by MRI, the cerebral cortex in healthy children mature earlier than their peers who have been diagnosed with ADHD. In the brain of hyperactive children after ending the formation of the brain centers responsible for attention and planning. According to researchers from the National Institute of Mental Health, hyperactive, these areas of the brain begin to fully operational three years later.
In order to objectively evaluate the degree of maturity of the cortex, the American experts carried out its measurements at various points (a total of 40 000 points), followed by conducting repeated studies for another three years. Doctors have found that in healthy children the thickness of the cerebral cortex reached the maximum performance for 7, 5 years, while their peers with ADHD, this was only 10, 5 years.
According to experts, after all children with ADHD were formed centers located in the frontal cortex, which controls the processes of concentration, motivation, short-term memory and determines the final behavior. The motor cortex, which controls movement, these children, on the contrary, formed faster than normal. In this particular brain development, researchers are inclined to see the reason why the diagnosis of ADHD children grow impatient and restless.
However, the delay in the development of certain parts of the brain, scientists are not considered as dangerous. "In general, the brains of children with ADHD is developing in a normal way," - say experts. Therefore, they explain, many restless ADHD "outgrow" the diagnosis. (READ MORE)
