# What causes ADHD in children? Canonical: https://pinnacleblooms.org/ask/what-causes-adhd-in-children Publisher: Pinnacle Blooms Network / Bharath Healthcare Laboratories Private Limited ADHD is not caused by parenting, screens or sugar. It is highly heritable and reflects natural differences in how the brain's attention and self-regulation systems develop. Some pregnancy and birth factors add to likelihood. A diagnosis is formed only at a Pinnacle centre under clinician care. *When a child can't sit still or stay focused, the first question every parent asks is simple: why? Here's what the science actually says.* ## In short ADHD is not caused by parenting, screen time, or too much sugar. The strongest evidence points to **biology** — it runs in families and is highly heritable, reflecting natural differences in how the brain's attention and self-regulation systems develop. Some pregnancy and birth factors (such as prematurity, low birth weight, or certain exposures during pregnancy) can add to the likelihood, but ADHD is best understood as a *difference in brain development*, not something a parent did or failed to do. ## What the science actually says **Genes lead the way.** ADHD is one of the most heritable of all childhood neurodevelopmental conditions — it commonly appears across siblings and parents. No single gene causes it; rather, many small genetic influences combine to shape how a child regulates attention, activity and impulse. **Brain development plays a part.** Research links ADHD to differences in the brain networks that manage focus, working memory and self-control. These are real, biological differences — which is exactly why a child genuinely *cannot* simply "try harder" to concentrate. **Some environmental factors add to likelihood** — being born prematurely or at very low birth weight, and certain exposures during pregnancy. These raise probability; they do not single-handedly cause ADHD. **What does NOT cause ADHD:** sugar, screens, vaccines, or a parent being too strict or too soft. Letting go of that guilt is the first healthy step. ## When to seek a developmental check If inattention, restlessness or impulsivity is showing up **across more than one setting** — home *and* school or playgroup — and is affecting your child's learning, friendships or daily life, that is a good reason for a structured developmental check. ADHD is usually recognised once a child is in a structured learning environment, often from around age 5–6. ## The Pinnacle way A clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed **only at a Pinnacle Blooms Network centre, under qualified clinician care** — never from an online form or a quiz.
