Overview : ADD/ADHD |
|
Attention-Deficit/Hyperactivity Disorder (ADHD) is a medical condition that affects the parts of the brain that control attention and activity. People with ADHD have greater difficulty than others in their ability to concentrate, sit still, and control impulsive behaviors. Some people with ADHD also have high activity levels, acting restless or even agitated. While most children have trouble paying attention or controlling their behavior at one time or another, children with ADHD struggle more with these things. Symptoms such as hyperactivity typically decrease over time, but for over half of individuals with ADHD, problems with attention and organization will remain. Sometimes symptoms can appear to worsen in adolescence, as demands increase in middle school. ADHD may cause issues at school, home, and in friendships. A child with ADHD might:
In the past, ADHD was sometimes called ADD (attention deficit disorder) when hyperactivity was not present. Now, people with ADHD are described in three categories: ADHD, Predominantly Inattentive Type: the category formerly referred to as ADD. This type makes it hard for the person to finish a task, organize, listen to instructions and follow conversations, and pay attention to details. Easily distractible and forgetful. ADHD, Predominantly Hyperactive-Impulsive Type: This type is usually diagnosed when the person’s greatest difficulties are sitting still and completing tasks. He or she may fidget and talk constantly. Children with this type may be especially active, feeling a frequent need to run, jump, or climb. Because the person with this type of ADHD often acts quickly without thinking first, they may have a hard time waiting their turn and following directions. Reckless behavior in these individuals can also lead to more injuries and accidents, including automobile accidents. They may interrupt others often, speak when not appropriate, or grab things from other people. ADHD, Combined Type: This type is diagnosed when symptoms from the two categories above are both present in equal amounts – the most common type. ADHD is usually discovered in childhood, although sometimes it’s not noticed until the teenage years or even adulthood. Even if it isn’t diagnosed until later in life, ADHD is something a person has at birth. It is not caused, as some used to believe, by eating too much sugar, watching too much television, or lack of proper parenting. Scientists are, however, studying possible risk factors for ADHD. The exact causes are still unknown, but current research points to a genetic link and also to potential risk factors including:
Doctors have found differences in brain chemicals called neurotransmitters (nur-ō-tranz-mit-ers) among people with ADHD. These are chemicals that take messages between brain cells. One example is dopamine (dō-puh-meen). This chemical stimulates the brain’s attention centers, and low amounts of it in a person’s brain may appear as ADHD symptoms.
Diagnosis There is no one test that can detect ADHD. Instead, a diagnosis is reached after a complete evaluation that takes many other possible explanations into consideration. Primary care doctors (Pediatrician or Family care doctors) may be responsible for determining and treating ADHD. Otherwise, specialist doctors like a psychiatrist, psychologist, or neurologist, may be needed to evaluate the person suspected of having ADHD. Requirements for diagnosis of ADHD - Behaviors must:
Doctors also must rule out other causes for adhd-like behavior, like major life stressors (divorce of parents, a move, change of school, or other major life events) and other possible diagnoses (depression, learning disability, anxiety, Tourette syndrome, etc.). The evaluation may include:
As of today, ADHD cannot be cured, but it can be successfully managed with the help of your doctor. For information on treatments, interventions, and helpful hints, please see the Current Practices section of this informational packet. Learning about ADHD can be confusing. Don’t be afraid to ask questions of your doctors, other families who have gone through it too, and our staff here at the Missouri Developmental Disability Resource Center. We’re here to help.
