Millions of US children have been diagnosed with ADHD Boys (13%) are more likely to be diagnosed with ADHD than girls (6%).
Children up to age 16 are diagnosed with ADHD if they have had at least six persistent symptoms of inattention and/or six persistent symptoms of hyperactivity-impulsivity present for at least 6 months.
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.
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.
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.
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.
Significant head injuries may cause ADHD in some cases. Prematurity increases the risk of developing ADHD. Prenatal exposures, such as alcohol or nicotine from smoking, increase the risk of developing ADHD. In very rare cases, toxins in the environment may lead to ADHD.
The short answer is no, says Stephanie Ruggiero, PsyD, a clinical psychologist at the Child Mind Institute. “About two-thirds of children who have ADHD will continue to meet criteria for ADHD by the time they're adults,” says Dr. Ruggiero. But, she says, that doesn't mean the symptoms stay the same.
Inattentiveness (difficulty concentrating and focusing)
The main signs of inattentiveness are: having a short attention span and being easily distracted. making careless mistakes – for example, in schoolwork. appearing forgetful or losing things.
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”.
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.
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.
Differences Between an ADHD Brain and a Non-ADHD Brain
Since the two go hand-in-hand, experts believe that lower levels of dopamine and norepinephrine are both linked to ADHD. An imbalance in the transmission of dopamine in the brain may be associated with symptoms of ADHD, including inattention and impulsivity.
Stimulants are the best and most common type of medication used to treat ADHD. There are only two stimulant medications, methylphenidate (the active ingredient in Ritalin, Concerta and other formulations) and amphetamine (the active ingredient in Adderall, Vyvanse and other formulations).
ADHD can reduce life expectancy by as much as 13 years, but its risk is reversible. Learn how to mitigate the risks in this video, with Russell Barkley, Ph. D.
