ADHD

Scientists are studying cause(s) and risk factors in an effort to find better ways to manage and reduce the chances of a person having ADHD. The cause(s) and risk factors for ADHD are unknown, but current research shows that genetics plays an important role.
In addition to genetics, scientists are studying other possible causes and risk factors including:
Brain injury
Exposure to environmental risks (e.g., lead) during pregnancy or at a young age
Alcohol and tobacco use during pregnancy
Premature delivery
Low birth weight

In most cases, ADHD is best treated with a combination of behavior therapy and medication. For preschool-aged children (4-5 years of age) with ADHD, behavior therapy, particularly training for parents, is recommended as the first line of treatment before medication is tried. What works best can depend on the child and family. Good treatment plans will include close monitoring, follow-ups, and making changes, if needed, along the way.

Managing Symptoms: Staying Healthy
Being healthy is important for all children and can be especially important for children with ADHD. In addition to behavioral therapy and medication, having a healthy lifestyle can make it easier for your child to deal with ADHD symptoms. Here are some healthy behaviors that may help:

Developing healthy eating habits such as eating plenty of fruits, vegetables, and whole grains and choosing lean protein sources
Participating in daily physical activity based on age
Limiting the amount of daily screen time from TVs, computers, phones, and other electronics
Getting the recommended amount of sleep each night based on age
