In this final part of my series on understanding Attention Deficit/Hyperactivity Disorder (ADHD), we delve more into the underlying mechanisms of the disorder.
Hyperactive flies can help us understand ADHD and learning disability.
Many researchers are seeking a better understanding of ADHD and the medications used to treat it by studying ADHD’s underlying mechanisms and working towards a better knowledge of this disorder. In this video Professor David Anderson explains how our current understanding of ADHD (and the learning disability which can accompany it) as merely chemical imbalances in dopamine and noradrenaline is not working and shows that by studying a strain of hyperactive fruit fly (Drosophila) we can study the different nerve pathways involved in ADHD and learning disability which will help in providing safer and more effective treatments.
Small cold-water fish
There is no cure for ADHD at this time. However a recent (2012) study in the Journal of the American Medical Association reports that fish consumption during pregnancy protects against ADHD in the child. In addition, many ADHD sufferers also report a beneficial effect of daily fish oil. If you are considering including fish in your diet then the study recommends small cold-water fish such as herring, mackerel, sardines and salmon rather than larger fish such as tuna which live much longer and thereby may accumulate the toxic metal mercury.
