The MTA Study


The NIMH funded the Multimodal Treatment of Attention Deficit Hyperactivity Disorder (MTA) study. It was a study of several treatments for almost 500 children with ADHD, including medication only medication and therapy combined therapy and community support, without medication The study spanned many sites, and entailed collecting follow-up data for several years (read more). The One Year Results In 2007, Jensen and a team of researchers (Jensen et al., 2007) explain that the 14 month results... more


ADHD Treatment


The AACAP has offered several recommendations for treatment of ADHD (Pliszka, 2007): The treatment plan for the ADHD patient should be comprehensive and “well-thought-out”: This requires providers to recognize ADHD as a chronic disorder which presents different developmental challenges over time. Thus, exploration of the many treatments (including medical and behavioral) and combinations of treatments that are available (for ADHD children, teens, and adults as well as for parents and... more


Is There A Genetic Cause For ADHD?


Is There A Genetic Cause For ADHD? What we know is that ADHD is associated with problems in dopamine receptors, or the neurons in the brain that respond to the neurotransmitter dopamine. There are five kinds of dopamine receptors (that have been identified) in the brain, and five genes (that have been identified) that code for the construction of these neurons. These kinds of neurons are simply numbered D1 through D5, and the associated genes that code for building these neurons are simply numbered... more


How Does ADHD Work? (Part II)

Model III – Deeper Brain Structure Dysfunction Another explanation for ADHD is a problem with the basal ganglia, and the corpus callosum just above the basal ganglia (Biederman et al, 2004). These are deeper brain structures, which serve as “switching stations” for information. In a typical brain, information passes through these structures, and a decision is made. If the information is important, then it is re-routed to the appropriate areas of the brain for processing; if it is... more


How Does ADHD Work? (Part I)


There are three basic models to explain ADHD: Model I – Frontal/Pre-Frontal Lobe Dysfunction The frontal lobes, and especially the pre-frontal lobes, are involved in executive reasoning and inhibition of responses(Biederman et al, 2004). To explain, when you weigh possible solutions to a problem, evaluating the strengths and weaknesses of each possible solutions and finally choosing one, you are engaging in executive reasoning. ADHD can be thought of as a deficit in focusing, or a difficulty... more
