ADHD in Adults (cont.)

ADHD in Adults Causes

Rather than having any single cause, attention deficit hyperactivity disorder (ADHD) develops from both genetic and life-experience risk factors. Individuals with ADHD tend to have problems developing efficient self-control skills and decision-making abilities.

Biologically, ADHD is a neurochemical and neuroanatomical disorder. People with ADHD are thought to have several chemicals (still to be determined) in the brain that are not present in the right quantities in the right places at the right times. These chemicals may work sometimes, but not always, and they are not under the individual's control. This is why people with ADHD have variable performance. Also, some nerve groups seem to be a bit out of position in the brain, causing delays or accelerations of nerve signals.

Risk factors for childhood ADHD are thought to include male gender, but some of that is known to be the result of the symptoms of ADHD potentially seeming less apparent in girls. Since ADHD in adults is equally identified in men and women, gender is not a risk factor for this disorder in adults. Other risk factors for ADHD are thought to include medical or mental-health issues in a father, trauma before birth, being the product of unintended pregnancy, and history of head trauma. Being breastfed is thought to be a protective factor against developing ADHD.
