Brain function and structure Other studies have suggested that people with ADHD may have an imbalance in the level of neurotransmitters in the brain, or that these chemicals may not work properly.
ADHD brains have low levels of a neurotransmitter called norepinephrine. Norepinephrine is linked arm-in-arm with dopamine. Dopamine is the thing that helps control the brain's reward and pleasure center. The ADHD brain has impaired activity in four functional regions of the brain.
One study found that kids with ADHD don't have the same brain connections as those without. An ADHD brain may have different connections between the frontal cortex and the visual processing area. This means that people with ADHD might process things differently than people without the condition.
ADHD is a long-term (chronic) brain condition that causes executive dysfunction, which means it disrupts a person's ability to manage their own emotions, thoughts and actions. ADHD makes it difficult for people to: Manage their behavior.
At the brain circuitry level, the superior longitudinal fasciculus (SLF) and cortico-limbic areas are dysfunctional in individuals with ADHD.
Though brain scans cannot yet reliably diagnose ADHD, some scientists are using them to identify environmental and prenatal factors that affect symptoms, and to better understand how stimulant medications trigger symptom control vs. side effects.
The cause(s) and risk factors for ADHD are unknown, but current research shows that genetics plays an important role. Recent studies link genetic factors with ADHD. In addition to genetics, scientists are studying other possible causes and risk factors including: Brain injury.
These may include hyperfocus, resilience, creativity, conversational skills, spontaneity, and abundant energy. Many people view these benefits as “superpowers” because those with ADHD can hone them to their advantage. People with ADHD have a unique perspective that others may find interesting and valuable.
What is attention deficit hyperactivity disorder? Attention deficit hyperactivity disorder (ADHD) is a neurobehavioral disorder marked by trouble controlling impulsive behavior, difficulty paying attention, or overactivity. It is one of the most common neurodevelopmental disorders of childhood.
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.
People with ADHD will have at least two or three of the following challenges: difficulty staying on task, paying attention, daydreaming or tuning out, organizational issues, and hyper-focus, which causes us to lose track of time. ADHD-ers are often highly sensitive and empathic.
Executive functions have other roles which affect how someone thinks. In people with ADHD, these executive dysfunctions impact thinking in numerous ways. People with ADHD don't really think faster than people without it, but it can sometimes seem like they do.
The brain networks of people with ADHD may take more time to develop and be less effective at relaying certain messages, behaviors, or information. These brain networks may function differently in areas such as focus, movement, and reward.
ADHD was the first disorder found to be the result of a deficiency of a specific neurotransmitter — in this case, norepinephrine — and the first disorder found to respond to medications to correct this underlying deficiency. Like all neurotransmitters, norepinephrine is synthesized within the brain.
ADHD neurotransmitters dopamine and norepineprine are found to be deficient in this mental disorder.
If your child has ADHD, they may have low levels of a brain chemical called dopamine. That's part of a mix of their genes, environment, and brain function that experts believe may cause ADHD.
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.
People seeking treatment for ADHD typically seek support from a psychologist, psychiatrist, or therapist rather than a neurologist. Neurologists typically treat conditions such as Parkinson's disease and brain injuries, not psychological disorders.
Is ADHD considered a disability? 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.
ADHD: a disabling condition
It is recognized as a disability under the 1992 Disability Discrimination Act.
Does ADHD affect IQ? A popular misconception is that all children with attention deficit hyperactivity disorder (ADHD) are naturally smarter and have a higher IQ than children without ADHD. However, there is no correlation between this condition and intelligence.
Some of the common foods that can cause ADHD reactions include milk, chocolate, soy, wheat, eggs, beans, corn, tomatoes, grapes, and oranges. If you suspect a food sensitivity may be contributing to your child's ADHD symptoms, talk to your ADHD dietitian or doctor about trying an elimination diet.
Millions of US children have been diagnosed with ADHD
Boys (13%) are more likely to be diagnosed with ADHD than girls (6%).
Many people think that ADHD is a result of trauma, but is it true? The answer is yes, but more for some people than others. The truth is that 90% of the time ADHD is not caused by trauma, but if the trauma is extreme enough, it can cause severe ADHD-like symptoms.
