Trav Le Bleu Posted 4 July 2009 Posted 4 July 2009 Shocking!! ADHD at Medical News Today Pediatric researchers have identified hundreds of gene variations that occur more frequently in children with attention-deficit hyperactivity disorder (ADHD) than in children without ADHD. Many of those genes were already known to be important for learning, behavior, brain function and neurodevelopment, but had not been previously associated with ADHD."Because the gene alterations we found are involved in the development of the nervous system, they may eventually guide researchers to better targets in designing early intervention for children with ADHD," said lead author Josephine Elia, M.D., a psychiatrist and ADHD expert at The Children's Hospital of Philadelphia. ADHD is the most common neuropsychiatric disorder in children, affecting an estimated 1 in 20 children worldwide. It may include hyperactive behavior, impulsivity and inattentive symptoms, with impaired skills in planning, organizing, and maintaining focus. Its cause is unknown, but it is known from family studies to be strongly influenced by genetics. "We took a systems biology approach, grouping genes into groups with common functions," said White. "We found that the sets of genes more likely to be changed in ADHD patients and families affected functions that made sense biologically." For instance, said White, the team found four deletions of DNA in a gene recently linked to restless legs syndrome, a type of sleep disorder common in adults with ADHD. Another deletion occurred in a gene for a glutamate receptor. Glutamate is a neurotransmitter, a protein that carries signals in the brain. While ADHD medications act on dopamine and serotonin, which are also neurotransmitters, this new finding may suggest an important role for glutamate as well, at least for some ADHD patients. "As we delve into the genetics of very complex diseases such as ADHD, we find many contributing genes, often differing from one family to another," added White. "Studying the functions of different genes allows us to identify biological pathways that may be involved in this neuropsychiatric disorder." :whistle:

stez Posted 5 July 2009 Posted 5 July 2009 just as an aside, back in the olden days, when ADHD was just called 'hyperactivity' my sister did used to go absolutely wappy after she has had orange squash to drink; up at all hours in the night wide awake as you like, unable to sit and be calm during the day and this happened whenever she had orange squash. so that was stopped and so did the 'hyperactive' behaviour. now the same has happened with my daughter, and we were told (re. my sister) that it was a reaction to a colouring so i presume it's the same with my kid. i'm happy to be proved wrong by people who know better than me
