What factor is NOT a risk factor for ADHD?

High birth weight is not considered a risk factor for ADHD. Research has identified various factors that may contribute to the development of ADHD, including genetic predisposition (evidenced by family history), prenatal exposures (such as drugs, alcohol, or environmental toxins), and experiences such as being in foster care or other forms of unstable living situations.

Family history plays a significant role since ADHD tends to run in families, suggesting a strong genetic component. Pre-natal exposure to drugs can adversely affect brain development, leading to an increased risk of behavioral and attention difficulties. Similarly, unstable living conditions associated with foster care can create environmental stressors that may influence the development of ADHD symptoms.

In contrast, high birth weight is generally not linked to an increased risk of ADHD. Some studies suggest that low birth weight is more commonly associated with developmental issues, but high birth weight does not carry the same association with ADHD, making it an atypical risk factor in this context.
