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. (See chart.)
Researchers examined data on more than 17,000 children in the United States in another study, published in Pediatrics. They found that compared with white children, Black children were 36 percent less likely and Latino children were 56 percent less likely to be diagnosed with ADHD.
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.
In 2021, research showed that for every 100 white children diagnosed with ADHD, there are 83 Black and 77 Hispanic children, and just 48 Asian children, with the diagnosis.
The highest rates emerged from Africa (8.5%) and South America (11.8%). Corroboration comes from a dimensional ADHD scale used in 21 countries. Japanese and Finnish children scored lowest, Jamaican and Thai children scored highest, and American children scored about average (7).
Around 1 in every 20 Australians has ADHD. While ADHD is more common in boys — it's under diagnosed in girls and adults. More than 3 in 4 children diagnosed with ADHD still have symptoms as an adult.
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 to date has shown ADHD may be caused by a number of things: Brain anatomy and function. A lower level of activity in the parts of the brain that control attention and activity level may be associated with ADHD.
The research confirmed previous studies showing ADHD was found more often in whites than Asians, blacks, Hispanics, and Pacific Islanders. The analysis found yearly increases of ADHD prevalence among all ethnic groups studied, including a three-fold increase in Asians, from 0.11% to 0.35% of the study population.
The prevalence of ADHD among Arab populations is variable according to published studies, ranging from 6-16 percent. That is more or less equivalent to the occurrence in the United States, where the prevalence is reported from 5-10 percent.
Does Socioeconomic Status Affect ADHD Diagnosis? One study found that kids who live in families below the federal poverty level are more likely to get an ADHD diagnosis compared to kids who don't. Another suggested the same. More specifically, the risk of diagnosis doubles for children of low socioeconomic status.
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 can reduce life expectancy by as much as 13 years, but its risk is reversible.
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.
Shankman: Simply put, ADHD is the brain's inability to produce as much dopamine, serotonin, and adrenaline as “regular” people's brains produce. Because of that, our brains have become “faster.” When managed right, that becomes a superpower. Have you found that you tend to think faster than most people? Yes.
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.
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.
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.
ADHD: a disabling condition
It is recognized as a disability under the 1992 Disability Discrimination Act.
What is ADHD? ADHD is a complex neurodevelopmental disorder affecting one in 20 Australians, which has an impact on their ability to have age-appropriate self-control, according to ADHD Australia.
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.
Studies have shown that symptoms of bipolar disorder often overlap with those of ADHD, making it hard to diagnose both of these disorders. Bipolar disorder is marked by mood swings between periods of intense emotional highs and lows.
