Discovery of the first common genetic risk factors for ADHD. A global team of researchers has found the first common genetic risk factors associated with attention deficit hyperactivity disorder (ADHD), a complex condition affecting around one in 20 children. Source 9n.
Genomes that are already changed does not always tell us how they were changed. We have known for a while that certain traits are effected by different stimulus. We need to find out why this is happening more and more. Is it the processed foods we are eating more and more of? Or is something else. I have a feeling that a lot of the rise in issues that our children are having from ADHD to Autism's is directly related to the chemicals that are being used in the process of food. Whether those chemicals are still in the processed foods or not is not clear but I would think that yes in minute numbers. The problem is those minute numbers increase with the more processed foods we ingest.
The sad thing is there big food producers will not always tell us the truth and even when some of them are banned in other countries they still produce it here in the USA to have American citizens consume products that may not be safe for them or their children,.
Genetic risk for ADHD manifest in brain structure in childhood. There is only scant scientific evidence on whether the genetic risk for developing specific psychiatric disorders or cognitive traits is manifest in brain structure from childhood and, to date, studies have focused primarily on adult populations. The question remains unanswered. Source 4o.
Maternal smoking during pregnancy increases risk of ADHD among offspring up to 3-fold. The higher the cotinine levels were in the mother's blood during pregnancy, the greater was the child's risk of developing attention deficit hyperactivity disorder (ADHD) later in life, showed an epidemiological study. Globally, it is the first study in which the connection between fetal nicotine exposure and diagnosis of ADHD was shown by measuring cotinine levels from pregnant maternal serum specimens. Source 6v.
