What Is ADHD And What Causes ADHD In Children?

The exact cause of ADHD is not fully understood, but research suggests a combination of genetic, neurological, and environmental factors. Genetics plays a significant role, as ADHD tends to run in families. Certain brain regions and neurotransmitters involved in regulating attention and impulse control may also be implicated. Environmental factors such as prenatal exposure to tobacco smoke, premature birth, low birth weight, and exposure to lead have been linked to an increased risk of developing ADHD.
