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.
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.
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.
Some families demonstrate transmission of ADHD in a pattern consistent with that of a Mendelian dominant trait.
Out of every four people diagnosed with ADHD, one of them has got a mom or dad who's got it, whether they know it or not. And the other three – if they don't have a parent who has it, usually they've got a grandparent or an uncle or aunt or cousin or brother or sister. It runs in families.
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 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.
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”.
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.
The CDC study, reported in March of this year, found overall, 14% of children 3-17 have ever been diagnosed with either ADHD or learning disability, including 17% of Black children, 15% of white children and 12% of Hispanic children.
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].
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.
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.
Yes, ADHD is considered a disability under the Americans with Disabilities Act (ADA) and the Rehabilitation Act of 1973 (Section 504). There are several types of disabilities, including but not limited to: learning disability. cognitive disability.
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.
The mind of a person with ADHD is full of the minutiae of life (“Where are my keys?” “Where did I park the car?”), so there is little room left for new thoughts and memories. Something has to be discarded or forgotten to make room for new information. Often the information individuals with ADHD need is in their memory…
The symptoms include an inability to focus, being easily distracted, hyperactivity, poor organization skills, and impulsiveness. Not everyone who has ADHD has all these symptoms. They vary from person to person and tend to change with age.
The brain's frontal lobes, which are involved in ADHD, continue to mature until we reach age 35. In practical terms, this means that people with ADHD can expect some lessening of their symptoms over time. Many will not match the emotional maturity of a 21-year-old until their late 30's.
Specifically, sugar stimulates dopamine in the brain, as well as opioid receptors, which causes cravings for it. For those with ADHD, sugar intake should be monitored closely since it can make ADHD symptoms worse.
For parents wondering if there is a cure for ADHD, the short answer is no, there is no “cure” for ADHD. While the treatment protocols utilized at the Drake Institute have proven to be effective in many cases, no treatment protocol works 100% of the time for every patient.
