The causes of ADHD are complex. Scientists are still actively researching and exploring to learn more about what causesADHD and what can protect children from developing ADHD.
Some researchers have examined whether mental health in parents affects ADHD risk in children.
One study, shown below, found that children whose parents had ADHD were over four times more likely to have ADHD themselves:
This is consistent with our understanding of how ADHD is passed through families.
ADHD has also been linked with other mental health disorders and parents beyond just ADHD.
A study looking at anxiety and depression, and ADHD found that mothers of children with ADHD were more likely to suffer from depression and anxiety:
This is consistent with our understanding of the link between anxiety and ADHD. Studies have shown that mental health conditions such as anxiety and depression can affect ADHD risk and how a patient experiences ADHD.
A parent’s health also plays a role in ADHD persistence. While most people with ADHD experience improvements as they age, some suffer from severe ADHD, even as adults.
A study found that one of the strongest predictors of children not getting better from ADHD as they get older is whether their parents have mental health issues.
Children whose parents have mental health issues with 30% more likely to have ADHD remain severe as they age into adulthood:
The article below has more information on the different factors linked to ADHD recovery:
One of the reasons why ADHD in parents may affect mental health in children is the effect ADHD can have on parenting.
Parenting requires focus, discipline, and attention. All of these are areas that those with ADHD can struggle with.
One study found that parents with ADHD were likelier to struggle with keeping a calm and disciplined home environment.
As described by the authors below, parents with ADHD, often struggle with organizing a home, providing consistent discipline, and providing support for children’s negative emotions.
Many factors contribute to ADHD risk. There is evidence that parents with poor mental health, particularly if they have ADHD, can contribute to a higher risk of ADHD in children. This comes in the form of genetics and potentially in the home environment and how a child is raised.
While this is still being explored, there is a clear link between ADHD and mental health in general. Based on the studies above, this link may be why parents' mental health is linked to ADHD risk.
