ADHD symptoms arise from executive dysfunction,[7][8][9] and emotional dysregulation is often considered a core symptom.[10][11][12] In children, problems paying attention may result in poor school performance. ADHD is associated with other neurodevelopmental and mental disorders as well as some non-psychiatric disorders, which can cause additional impairment, especially in modern society. Although people with ADHD struggle to focus on tasks they are not particularly interested in completing, they are often able to maintain an unusually prolonged and intense level of attention for tasks they do find interesting or rewarding; this is known as hyperfocus.
The precise causes of ADHD are unknown in the majority of cases.[13][14] Genetic factors play an important role; ADHD tends to run in families and has a heritability rate of 74%.[15] Toxins and infections during pregnancy and brain damage may be environmental risks.
