Risk factors
By Mayo Clinic staffRisk factors for ADHD may include:
- Blood relatives (such as a parent or sibling) with ADHD or another mental health disorder
- Exposure to environmental toxins — such as lead, found mainly in paint and pipes in older buildings
- Maternal drug use, alcohol use or smoking during pregnancy
- Maternal exposure to environmental poisons — such as polychlorinated biphenyls (PCBs) — during pregnancy
- Premature birth
Although sugar is a popular suspect in causing hyperactivity, there's no reliable proof of this. Many things in childhood can lead to difficulty sustaining attention, but that is not the same as ADHD.
