Available evidence suggests that ADHD is genetic—passed down from parent to child. ADHD seems to run in at least some families. At least one-third of all fathers who had ADHD in their youth have children with the condition. What's more, the majority of identical twins share the ADHD trait.
A comparison with DNA from unaffected patients showed an abnormality in the sequences. Thayer's study shows that the ADHD group of children had larger and more frequent variations. Fathers with ADHD will pass this code discrepancy to offspring. Barkley explains that the heritability of ADHD runs around 80 percent.
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.
Heritability in ADHD
According to a recent meta-analysis of twin studies, the heritability of ADHD is estimated at 77–88% [8]. The magnitude is therefore similar to that of autism spectrum disorder (about 80%), bipolar disorder (about 75%), and schizophrenia (about 80%) [6].
A rare, autosomal recessive inherited disorder usually caused by mutations in the THRB gene.
While the exact causes of ADHD have not been identified, genetic studies show there is a strong hereditary component, with an up to a 91 percent likelihood of passing the disorder to your children.
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.
Attention deficit hyperactivity disorder (ADHD), one of the most prevalent childhood disorders today, is generally more likely to be diagnosed and treated in boys than in girls.
Symptoms of ADHD tend to be noticed at an early age and may become more noticeable when a child's circumstances change, such as when they start school. Most cases are diagnosed when children are under 12 years old, but sometimes it's diagnosed later in childhood.
ADHD runs in families. 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.
Overall, about 15 percent of later-born siblings in the ADHD and ASD risk groups were diagnosed with ADHD or ASD, compared with about 2 percent of children whose older siblings had neither disorder.
Autism spectrum disorder and ADHD are related in several ways. 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.
Many women with ADHD say they feel restless all the time. They might have a hard time relaxing or tap their fingers and toes incessantly. Adults with impulsivity problems might spend irresponsibly and are more likely to get into car accidents. They also have higher rates of divorce and addiction.
ADHD, also called attention-deficit disorder, is a behavior disorder, usually first diagnosed in childhood, that is characterized by inattention, impulsivity, and, in some cases, hyperactivity.
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.
Barkley, PhD. “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.
Girls are also less likely to be diagnosed earlier because they often display more symptoms of anxiety. Medical providers may only treat a female patient's anxiety or depression without evaluating for ADHD. Hormones, which affect the symptoms of both ADHD and anxiety, can complicate things.
There is no specific physical test or written test that can make the diagnosis of ADHD. It is a diagnosis based on the child's history of behavioral symptoms at home and at school.
To date, no treatments cure ADHD, although available therapies offer symptomatic relief. Current management of ADHD is based on either non-pharmacologic or pharmacologic treatments as well as the combination of the two.
Overall population incidence is felt to be 8%-10%. Several investigations have demonstrated that children who have ADHD usually have a least one close relative (child or adult) who also has ADHD. At least one-third of all fathers who have ADHD will produce a child with ADHD.
So, are you born with ADHD? Yes, the disorder tends to run in families – but you may not display the symptoms throughout your whole life. Being born with ADHD is known to have its limiting factors, but with support in managing your symptoms, you can expect to see great improvements.
Risk factors
Blood relatives, such as a parent or sibling, with ADHD or another mental health disorder. Exposure to environmental toxins — such as lead, found mainly in paint and pipes in older buildings. Maternal drug use, alcohol use or smoking during pregnancy. Premature birth.
A well-balanced diet, exercise, and meditation are all good options for individuals looking to reduce their ADHD symptoms. However, while these natural ADHD remedies may reduce the severity of certain ADHD symptoms, they do not address the individual's underlying brain dysregulation.
