There are a lot of cases to look at on what causes the rise of ADHD, it can be genetic factor or environmental factor. How is it a deal to handle? What ways to intervene the causes of ADHD? Here are some insights and points that Dr. Mercola about the causes in rise of ADHD.
By Dr. Mercola
According to a 2010 US government survey, 1 in 10 American children now has attention deficit hyperactivity disorder (ADHD)—a 22 percent increase from 2003.
ADHD makes it hard for children to pay attention and control impulsive behavior, and an increasing number of older children, including high school students, are now being labeled as having ADHD. Adult ADHD is also becoming more prevalent.
As reported by the Las Vegas Guardian Express, nearly 11 percent of American kids are labeled with the disorder. More than twice as many boys are diagnosed with ADHD than girls—one in five, compared to one in 11. The featured article speculates about the cause behind these rising numbers.
Some experts feel the increase could be due to increased awareness and better diagnosis, but I think you’ll find it interesting that this trend also coincides with increased prevalence of the pervasive weed killer, glyphosate, in the American food supply.
There’s also plenty of room for overdiagnosis. In fact, an ADHD diagnosis is often made on the subjective observations of teachers or guardians, based on signs that nearly every child will display at some point. Aggravating factors, such as diet or home environment, are oftentimes overlooked entirely.
The featured article actually points out some interesting correlations between ADHD diagnoses and changes to the American educational system that might help explain how, if not why, so many children are misdiagnosed or flat out falsely diagnosed.
What Is ADHD?
But before we get into potential causes for the uptick in prevalence, let’s review how ADHD is qualified in the first place. The disorder involves a cluster of symptoms that includes inattention, hyperactivity, and impulsive behaviors.
Often, children with ADHD struggle in school and have difficulty managing interpersonal relationships. They also tend to suffer from low self-esteem. The similar term attention deficit disorder (ADD) has largely been replaced with ADHD, as it describes two of the most common symptoms of the condition, inattention, and hyperactive-impulsive behavior.
Diagnosing ADHD really comes down to a matter of opinion, as there is no physical test, like a brain scan, that can pinpoint the condition. This could change, however. According to a recent study, a newer MRI method called magnetic field correlation imaging that can detect low iron levels in the brains of children with ADHD could potentially help parents and patients make better informed decisions about treatment. As reported by Medicine.net:
“Psychostimulant drugs used to treat ADHD affect levels of the brain chemical dopamine. Because iron is required to process dopamine, using MRI to assess iron levels in the brain may provide a noninvasive, indirect measure of the chemical, explained study author Vitria Adisetiyo… If these findings are confirmed in larger studies, this technique might help improve ADHD diagnosis and treatment…
The [magnetic field correlation imaging] scans revealed that the 12 ADHD patients who'd never been treated with psychostimulant drugs such as Ritalin had lower brain iron levels than those who'd received the drugs and those in the control group. The lower iron levels in the ADHD patients who'd never taken stimulant drugs appeared to normalize after they took the medicines.”
At present, diagnosis is dependent on subjective evaluation, and, for better or worse, teachers can play a significant role in this evaluation. Most children with ADHD will display a combination of inattention and hyperactive-impulsive behavior.
Many of these “symptoms” could describe virtually any child, or most children, on any given day. Hence, those who display these symptoms at school but not at home or with friends are not considered to have ADHD. Ditto for children who display symptoms at home but not at school.
Only children who struggle with inattention and hyperactive or impulsive behaviors around the clock are deemed to have ADHD—or at least they should be. According to a 2010 study, an estimated 20 percent of children are misdiagnosed with ADHD.
What Causes Behavioral Difficulties?
Behavioral problems clearly do exist, and do appear to be more prevalent than in decades past, with or without the ADHD label. The question on everyone’s mind is what’s causing it? The cause of ADHD remains elusive, although there are many contending culprits, including poor nutrition and environmental toxins ranging from food- and vaccine additives to agricultural chemicals.
For example, a 2006 study9 found that a mother's use of cigarettes, alcohol, or other drugs during pregnancy could increase the risk for ADHD. The study also suggested that exposure to lead and/or polychlorinated biphenyls (PCBs) can cause ADHD symptoms. Pesticide exposure has also been linked with ADHD.
Unfortunately, few are focusing on basic nutrition, which I believe is a key factor. We know that the food choices of most children and adults today are incredibly poor, and how can you possibly expect a child to have normal behavior if he is fed refined grains, sugars, and processed foods loaded with chemicals and largely devoid of natural nutrients?
Five Dietary Factors to Address if Your Child Has ADHD
Five dietary factors of particular concern are the following. If your child struggles with behavioral difficulties, whether he or she has been diagnosed with ADHD or not, I strongly recommend addressing all of these factors:
- Too much sugar. High sugar content and starchy carbohydrates lead to excessive insulin release, which can lead to falling blood sugar levels, or hypoglycemia. Hypoglycemia, in turn, causes your brain to secrete glutamate in levels that can cause agitation, depression, anger, anxiety, and panic attacks.
Besides that, sugar promotes chronic inflammation in your body, and many studies have demonstrated the connection between a high-sugar diet and worsened mental health.
- Gluten sensitivity. The evidence suggesting that gluten sensitivity may be at the root of a number of neurological and psychiatric conditions, including ADHD, is quite compelling. According to a 2011 study, celiac disease is “markedly overrepresented among patients presenting with ADHD,” and a gluten-free diet has been shown to significantly improve behavior in kids. The study went so far as to suggest celiac disease should be added to the ADHD symptom checklist.
- Too few beneficial bacteria. As explained by Dr. Natasha Campbell-McBride, a medical doctor with a postgraduate degree in neurology, toxicity in your gut can flow throughout your body and into your brain, where it can cause symptoms of autism, ADHD, dyslexia, dyspraxia, depression, schizophrenia, and other mental disorders. Reducing gut inflammation is imperative when addressing mental health issues, so optimizing your child’s gut flora is a critical step.

- Animal-sourced omega-3 deficiency. Research has shown that kids low in omega-3 fats are significantly more likely to be hyperactive, struggle with learning disorders, and display behavioral problems. Omega-3 deficiencies have also been tied to dyslexia, violence, and depression. A clinical study published in 2007 examined the effects of krill oil on adults diagnosed with ADHD. In that study, patients improved their ability to concentrate by an average of over 60 percent after taking a daily 500mg dose of krill oil for six months. They also reported a 50 percent improvement in planning skills, and close to 49 percent improvement in social skills.
- Food additives and GMO ingredients. A number of food additives are thought to worsen ADHD, and many have subsequently been banned in Europe. Potential culprits to avoid include Blue #1 and #2 food coloring; Green #3; Orange B; Red #3 and #40; Yellow #5 and #6; and sodium benzoate, a preservative.
Recent research also shows that glyphosate, the active ingredient in Monsanto’s Roundup herbicide, used in large quantities on genetically engineered Roundup Ready crops, limits your body’s ability to detoxify foreign chemical compounds. As a result, the damaging effects of those chemicals and environmental toxins are magnified, and may result in a wide variety of diseases, including brain disorders that can affect behavior.
Additional Strategies to Relieve ADHD Symptoms
Besides addressing your child’s nutrition, as described in the two sections above, I also recommend implementing the following strategies:
- Clear your house of dangerous pesticides and other commercial chemicals.
- Avoid commercial washing detergents and cleaning products used on clothes, and replace them with naturally derived cleaning products free of added perfumes, softeners, etc.
- Spend more time in nature. Researchers have found that exposing ADHD children to nature is an affordable, healthy way of controlling symptoms.
- Investigate sensory therapy and emotional wellness tools. Instead of looking for a quick fix, encourage ADHD sufferers to talk, and find out what emotions are causing issues. You may also want to consider energy psychology tools such as the Emotional Freedom Techniques (EFT) to improve emotional coping and healing.
