ADHD: Your Guide to Childhood ADHD (cont.)
What causes ADHD?
The exact cause of ADHD is not known, although researchers continue to study the brain for clues. They suspect that there are several factors that may contribute to the condition, including:
The following are other factors that may contribute to the development of ADHD or that may trigger symptoms:
Eating too much sugar does not cause a child to develop ADHD. A proper diet is essential, though, for normal development in children. ADHD is also not caused by watching too much TV, a poor home life, poor schools, or food allergies.
How common is ADHD?
ADHD is the most commonly diagnosed mental disorder of children and is more common in boys than in girls. It most often is discovered during the early school years, when a child begins to have problems paying attention. ADHD can continue into the teen years and on into adulthood.
How is ADHD diagnosed?
If symptoms are present, the doctor will begin an evaluation by taking a complete medical history and doing a physical examination. There are no laboratory tests for ADHD. The doctor, though, may use various tests -- such as blood tests -- to determine if there is a physical disorder or other problem causing the symptoms.
Certain mental illnesses, such as depression and anxiety disorders, have some symptoms that are similar to those of ADHD. For that reason, a complete psychiatric assessment is needed to accurately diagnosis ADHD.
If no physical disorder is found, the child may be referred to a specialist in childhood development disorders. That may be a child and adolescent psychiatrist or psychologist, a pediatric neurologist, a developmental pediatrician, or another health professional. It should be someone specially trained to diagnose and treat ADHD. The doctor bases his or her diagnosis on the child's symptoms and behavior. The doctor may ask for input from the child's parents, teachers, and other adults who are familiar with the child's symptoms.
Researchers all agree that ADHD is not an adult-onset disorder. To be ADHD, symptoms must be verified as being present from childhood. Adults who are thought to have ADHD will be asked questions about their childhood. In particular, they will be asked about such things as:
The answers will help the doctor make an accurate ADHD diagnosis.
What is the treatment for ADHD?
ADHD cannot be cured. But many of the symptoms that interfere with functioning and cause distress can be controlled. Treatment for ADHD often includes a combination of medication and various psychosocial therapies.
Medication: Certain medications called stimulants may be used to help control hyperactivity and impulsive behavior and increase attention span. Commonly used stimulants include:
Sometimes stimulant drugs have worrisome side effects for children. In that case, nonstimulant medications such as Intuniv or Strattera may be prescribed for children with ADHD who are older than 6.
Psychosocial therapies: These are treatment approaches that focus on the behavioral, psychological, social, and work/school problems associated with the illness. Psychosocial therapies that may be used for ADHD include:
