Attention-Deficit/Hyperactivity Disorder (ADHD) is a neurobiological disorder that is characterized by developmentally inappropriate levels of inattention, impulsivity, and hyperactivity. Between 3% and 7% of school-aged children are affected by ADHD. ADHD is a lifespan condition that affects children, adolescents and adults of all ages. It affects both males and females, and people of all races and cultural backgrounds. Current research has found strong evidence that the primary cause of ADHD is genetic, due to the combined effect of several different genes. This means that ADHD runs in families. If a parent has ADHD, his or her child has more than a 50% chance of also being diagnosed with ADHD. Although environmental factors and prenatal and post-natal injuries can play a role in the cause of ADHD, twin studies have shown that 80% of problems with inattention, hyperactivity and impulsivity are the results of genetic factors. Current research does not support the idea that ADHD is caused by excessive sugar intake, food additives, excessive viewing of television, or poor parenting skills. Research on adult ADHD is still in an early stage of development. The current criteria for ADHD emphasize a childhood presentation, and there is a growing body of evidence that suggests that the diagnostic features of ADHD take a different form in adults. One example of this is within the area of hyperactivity. Although hyperactivity can be a common feature among children with ADHD, it is likely to be less overt in adults. The "on the go" behavior seen in children with ADHD is replaced in adults with restlessness, difficulty relaxing, and a feeling of chronically being on edge. This issue of LDA (Learning Disability Association) of Minnesota's "NetNews" considers the definition of ADHD; ADHD subtypes; adults and ADHD; and strategies for teaching.
