And kids can have ADHD without having any family risk. Other non-genetic factors can be involved. Knowing that ADHD is genetic can be helpful in many ways. But it can also lead to difficult feelings.
Anywhere from one-third to one-half of parents with ADHD will have a child with the disorder. There are genetic characteristics that seem to be passed down. If a parent has ADHD, a child has more than a 50% chance of having it. If an older sibling has it, a child has more than a 30% chance.
If both parents have ADHD, will your child? According to the National Institute of Mental Health , many studies suggest that ADHD runs in families and is highly inheritable. This means that if one or both parents have ADHD, there is a significantly increased chance that your child will develop ADHD in their lifetime.
The disorder begins in childhood, but somewhere between 30 to 70 percent of sons will also be fathers with ADHD. A number of published studies show a clear link to genetics, but it is not 100 percent conclusive. There may be other factors involved or genetics may not be behind each incident.

Genetics. ADHD tends to run in families and, in most cases, it's thought the genes you inherit from your parents are a significant factor in developing the condition. Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves.
Causes of ADHD
Recent studies link genetic factors with ADHD. In addition to genetics, scientists are studying other possible causes and risk factors including: Brain injury. Exposure to environmental risks (e.g., lead) during pregnancy or at a young age.
ADHD is not on the autism spectrum, but they have some of the same symptoms. And having one of these conditions increases the chances of having the other. Experts have changed the way they think about how autism and ADHD are related.
ADHD makes it harder for kids to develop the skills that control attention, behavior, emotions, and activity. As a result, they often act in ways that are hard for parents manage. For example, because they are inattentive, kids with ADHD may: seem distracted.
ADHD can be diagnosed as early as four years old. To be diagnosed between the ages of four and 16, a child must show six or more symptoms for more than six months, with most signs appearing before age 12.
Heritability in ADHD
According to a recent meta-analysis of twin studies, the heritability of ADHD is estimated at 77–88% [8].
The answer to this question depends on several factors. The biggest cause of ADHD is genes,1 which means that ADHD does run in families. Even if no one in your extended family has officially been diagnosed with ADHD, you might notice family members with characteristics and traits that resemble ADHD.
Untreated ADHD in adults can lead to mental health disorders like anxiety and depression. This is because ADHD symptoms can lead to focus, concentration, and impulsivity problems. When these problems are not managed effectively, they can lead to feelings of frustration, irritability, and low self-esteem.
ADHD is also three times more common in males than females, and subtypes tend to have a different prevalence. Due to this discrepancy in the prevalence of ADHD among males and females, researchers have undertaken studies to explore the sex differences in ADHD and the possible cause of the discrepancy.
In general, ADHD doesn't get worse with age. Some adults may also outgrow their symptoms. But this is not the case for everyone.
“Children diagnosed with ADHD are not likely to grow out of it. And while some children may recover fully from their disorder by age 21 or 27, the full disorder or at least significant symptoms and impairment persist in 50-86 percent of cases diagnosed in childhood.
Some of the common foods that can cause ADHD reactions include milk, chocolate, soy, wheat, eggs, beans, corn, tomatoes, grapes, and oranges. If you suspect a food sensitivity may be contributing to your child's ADHD symptoms, talk to your ADHD dietitian or doctor about trying an elimination diet.
Many people think that ADHD is a result of trauma, but is it true? The answer is yes, but more for some people than others. The truth is that 90% of the time ADHD is not caused by trauma, but if the trauma is extreme enough, it can cause severe ADHD-like symptoms.
What's more, chronic prenatal stress increases the likelihood that a child will have ADHD or other conditions. One 2018 study found that mothers who experienced high levels of stress during their pregnancy were more than twice as likely as less-stressed mothers to have a child diagnosed with ADHD or conduct disorder.
