It is for these reasons that some individuals with ADHD have a family or genetic history of the disorder. Many of those without a family history, though, show the same brain dysfunction due to toxins that disrupt the neuro-endocrine system.
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.
Neurotransmitters — chemicals that help transmit signals from one nerve cell to another — also play a role in ADHD. Although researchers have discovered these brain differences, they don't completely understand why they occur and lead to symptoms of ADHD. But current research shows that genetics plays a vital role.
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.
What are the neurotransmitters involved in ADHD? While there's no known specific cause for ADHD, varying dopamine levels, norepinephrine, and serotonin in the brain can contribute to the severity of its symptoms.
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.
Research has also suggested that exposure to mold may be associated with attention deficit hyperactivity disorder (ADHD). A study published in the Journal of Attention Disorders found that children exposed to mold in their homes were more likely to be diagnosed with ADHD.
Some people are sensitive to molds. For these people, exposure to molds can lead to symptoms such as stuffy nose, wheezing, and red or itchy eyes, or skin. Some people, such as those with allergies to molds or with asthma, may have more intense reactions.
Improving Focus for Individuals with ADD and ADHD
Individuals who struggle with attention deficit disorder (ADD) or attention-deficit/hyperactivity disorder (ADHD) use hyperbaric oxygen therapy to improve their mental focus and communicate more clearly.
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.
In general, ADHD doesn't get worse with age. Some adults may also outgrow their symptoms. But this is not the case for everyone.
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.
Trauma and traumatic stress, according to a growing body of research, are closely associated with attention deficit hyperactivity disorder (ADHD or ADD). Trauma and adversity can alter the brain's architecture, especially in children, which may partly explain their link to the development of ADHD.
As you know, one trademark of ADHD is low levels of the neurotransmitter dopamine — a chemical released by nerve cells into the brain. Due to this lack of dopamine, people with ADHD are "chemically wired" to seek more, says John Ratey, M.D., professor of psychiatry at Harvard Medical School in Boston.
ADHD can reduce life expectancy by as much as 13 years, but its risk is reversible.
“The typical person will be wide awake at 3 or 4 a.m. and have to get up at 7 to go to work.”Like everyone else, ADHD adults need seven or eight hours of sleep a night to promote health and prevent fatigue during the day, says psychiatrist Clete Kushida, M.D., Ph.
By Dr. David Velkoff. Ring of Fire ADD is a type of ADD characterized by abnormally increased activity in multiple areas of the brain, which in individuals on qEEG brain mapping scans can appear as over activity or overstimulation.
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…
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.
Attention-deficit/hyperactivity disorder (ADHD) is one of the most common mental disorders affecting children.
Restlessness and fidgety behavior associated with ADHD can be reduced by taking exercise breaks. Walking and running, and activities like yoga or meditation that incorporate deep breathing and mindfulness can be beneficial and induce relaxation and calm.
A: ADHD brains need more sleep, but find it doubly difficult to achieve restfulness. It is one of those ADHD double whammies: ADHD makes it harder to get enough sleep, and being sleep deprived makes it harder to manage your ADHD (or anything else).
