Causes of ADHD:
Although there have been many studies, researchers still don’t know the exact causes of ADHD. Scientists have, however, discovered a strong genetic link as ADHD can run in families. Over 20 genetic studies show evidence that ADHD can be inherited. That having been said, ADHD is a complex disorder, caused by several genes interacting.
Environmental factors can also increase the chances of getting ADHD. These can include premature birth or low birth weight, a brain injury, or exposure to pesticides or lead in early childhood.
Scientists continue to study the relationship between environmental factors and ADHD. They highlight, however, that many factors may contribute, and there is no one cause, that is common in every case.
At one stage, scientists thought that smoking during pregnancy or stress during pregnancy might elevate the chances of having ADHD, but current evidence doesn’t show this. Further research is being undertaken in this area.
Children with ADHD can have their symptoms aggravated by things like sugar consumption, family stress like poverty or fighting, watching too much television, or enduring traumatic experiences. These things, however, DO NOT cause ADHD.
Having ADHD might contribute to family conflict. Having stress in the family can result in antisocial behaviour, and it can change how ADHD presents.
Once again, parenting styles can have an impact on ADHD, but they do not cause the disorder. With ADHD being a brain disorder, research is currently being done to more clearly recognise the areas and pathways involved.
