Do genes determine your brain's abilities, or can you retrain the brain to overcome inherited problems, such as helping a learning-impaired child to read?

How does this article relate to me?
This article suggests that specialized training may help individuals with a variety of brain disorders, including dyslexia, language problems and autism. In fact, we have known for many years that training and education can have a major impact on these conditions. What's new about this research is greater insight into the way that training physically changes the wiring of the brain.
The "nature versus nurture" debate has fascinated scientists for years. How much are we shaped by our emotional and social environment, compared with the "hard-wiring" that comes from our genes? The answer is not straightforward. This research furthers blurs the distinction between brain chemistry and behavior, since it appears that behavior can change the brain as much as the brain dictates the behavior.
On a practical level, this research should bolster our support for programs such as Head Start, and early intervention efforts for children with autism and developmental delays.
What changes do I need to make?
This article tells us little about the researchers specific approach to retraining the brain. Therefore, it's hard to make specific recommendations.
However, this type of research reinforces the need to identify learning disabilities and behavioral problems early. If you have concerns about your own child, be sure to speak to your pediatrician. If your child is already suspected of having a problem such as dyslexia or autism, make every effort to ensure that he or she is getting the help that is needed.
What can I expect in the future?
As we learn more about the way that training affects the brain, we can design better programs to correct conditions such as dyslexia or autism. Expect more research on the fundamental mechanisms of brain development, as well as practical research that focuses on behavioral solutions that work.
