Is ADHD inherited from Mom or Dad? You can inherit genes that boost risk for ADHD from your mother, from your father or from both parents. In a recent Norwegian study, inherited risk was somewhat higher when a child's mother had ADHD compared to their father, but researchers weren't certain why that would be.
Research shows that parents and siblings of someone with ADHD are more likely to have ADHD themselves. However, the way ADHD is inherited is likely to be complex and is not thought to be related to a single genetic fault.
Some families demonstrate transmission of ADHD in a pattern consistent with that of a Mendelian dominant trait.
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.
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.
Similar to the hyperactive symptoms, impulsive symptoms are typically seen by the time a child is four years old and increase during the next three to four years to peak in severity when the child is seven to eight years of age.
Age of Onset
More severe cases of ADHD in children, as described by parents, were diagnosed earlier. The median age of diagnosis for severe ADHD was 4 years. The median age of diagnosis for moderate ADHD was 6 years. The median age of diagnosis for mild ADHD was 7 years.
Studies show that if you have ADHD, your children have about a 35% chance of acquiring it; if a child has it, there is a 50% likelihood that one of his or her parents does as well.
The Family Connection
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.
Heritability in ADHD
According to a recent meta-analysis of twin studies, the heritability of ADHD is estimated at 77–88% [8].
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.
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.
Rather, the rise seems to be due to an increase in access to healthcare; a decrease in stigmatization about receiving mental health care; and greater awareness of the symptoms of ADHD among clinicians, guardians, educators, and patients. In the past, ADHD was only diagnosed in children who were hyperactive.
ADHD Statistics: Demographics, Race & Ethnicity
Black children aged 3 to 17 years are more likely to have ever been diagnosed with ADHD or a learning disability (16.9 percent) compared to white (14.7 percent) and Hispanic children (11.9 percent).
The impact of ADHD on parenting
Parents with ADHD may feel overwhelmed and stressed, which can impact their mental health and well-being. They may also struggle to provide a stable and consistent home environment for their children, which can impact their emotional and social development.
Autism is very distinct from ADHD, but the core symptoms of ADHD-Combined type, i.e., attention deficit, impulsivity, and hyperactivity, would appear to also be features of autism. ASD and ADHD are neurobiological disorders characterized by similar underlying neuropsychological “deficits”.
Is ADHD inherited from Mom or Dad? You can inherit genes that boost risk for ADHD from your mother, from your father or from both parents.
Genetic screening cannot determine if a person has ADHD. Genetic screening may be helpful to a prescriber in selecting medications to treat ADHD and related conditions. Genetic screening may reveal information about other conditions that will need to be considered.
Although the exact cause of autism is still unknown, there is evidence to suggest that genetics play a significant role. Since autism is less prevalent in females, autism was always thought to be passed down from the mother. However, research suggests that autism genes are usually inherited from the father.
Conclusions: These results provide epidemiological evidence showing that young and advanced maternal age at childbirth are associated with ADHD and LD risk.
Mothers with ADHD are dynamic, socially anxious, creative, disorganized, passionate, emotionally sensitive, and sometimes all of the above at the same time. No two moms with ADD are alike, but many of their children recall similar snapshots of growing up under the umbrella of neurodivergence.
Research shows that childhood trauma can shape how certain areas of your brain form. That includes stress-sensitive structures and connections that control how you think, feel, and act. Early life stress may result in changes that cause you to have common ADHD symptoms, including: An ongoing sense of fear.
In a comprehensive study by Deloitte, researchers found that the disorder's worldwide prevalence ranges from 2% to 5%, encompassing both children and adults3. In Australia, ADHD is one of the most common neurodevelopmental disorders, affecting 6-7% of the population4.
The easiest way to get diagnosed and treated for ADHD if you are an adult is to approach your GP. Most GPs have a good understanding of ADHD. More importantly, as community-based health workers GPs have a wide-ranging understanding of medical and social issues that can affect one's cognitive function.
