Understanding ADHD

What is ADHD?

Attention-Deficit/Hyperactivity Disorder is a neurodevelopmental condition affecting both children and adults characterised by patterns of inattention, hyperactivity and impulsivity that can impact daily life.

ADHD is estimated to affect around 5–10% of children and 2–5% of adults worldwide. Figures vary with diagnostic criteria and population, but what stays constant is that ADHD is real, common, and highly manageable with the right support.

What causes ADHD?

The exact causes of ADHD are not fully understood, but research suggests it results from a combination of genetic, environmental and neurological factors. Specific genes have been associated with an increased risk, but ADHD is not determined by genetics alone. Prenatal exposure to toxins, premature birth, low birth weight and certain brain injuries may also contribute.
