ADHD risk factors encompass both genetic and environmental components that significantly impact child development. Family history plays a crucial role in ADHD development, with genetic factors contributing substantially to the condition's heritability. Environmental risk factors include premature birth, low birth weight, and maternal smoking during pregnancy, which can compromise fetal development and increase ADHD likelihood. These biological factors create vulnerabilities that may manifest as attention difficulties, hyperactivity, and impulsivity in affected children.

Socioeconomic factors represent critical environmental influences on ADHD development and management. Children from lower-income families face multiple challenges including limited access to prenatal care, inadequate nutrition during pregnancy, and unstable housing situations that disrupt educational continuity. Frequent school changes due to housing instability, parental divorce, and economic pressures create additional stress that can exacerbate ADHD symptoms. These socioeconomic disparities highlight how environmental stability and resources directly impact children's developmental outcomes.

Lead exposure emerges as a particularly concerning environmental risk factor for ADHD, especially in older buildings and schools with outdated plumbing systems. Even minimal lead exposure can trigger genetic predispositions to ADHD, making clean water access essential for children's neurological development. Healthcare providers must conduct comprehensive developmental and birth histories when evaluating ADHD, asking detailed questions about family behavioral patterns rather than simply inquiring about formal diagnoses, as older generations may have undiagnosed ADHD manifesting through impulsive behaviors, job instability, or recurrent accidents.
