Here, we separate fact from autism fiction about the causes of ADHD.
causes of ADHD attention deficit disorder
by Kristin Koch Because attention deficit hyperactivity disorder causes of ADHD (ADHD) symptoms—inattention attention deficit disorder, autism impulsivity, and/or hyperactivity—affect a child's ability to learn and get along with what causes ADHD others, some people think an ADHD child's behavior is caused by causes of ADHD lack of discipline autism, a chaotic family life, or even too much TV attention deficit disorder .
causes of ADHD
In fact, research suggests that ADHD is largely a genetic disorder.
what causes ADHD
However, some environmental factors may play a role as well. Here, we separate fact from fiction about the causes of ADHD.
Pesticides
Research does suggest a possible link between ADHD and pesticides.
A 2010 study in Pediatrics found that children with higher urine levels of organophosphate, a pesticide used on produce, had higher ADHD rates.attention autism deficit disorder another 2010 study showed that women with higher urine levels of organophosphate were more likely to have a child with ADHD.
attention deficit disorder the studies suggest a possible link, but can't prove that pesticides cause ADHD. Marcy Rosen Levitt, PTSD, who works with ADHD patients in causes of ADHD attention deficit disorder private practice in the Los Angeles area, recommends buying organic attention deficit disorder varieties of fruits and vegetables,what causes ADHD especially those prone to high levels of pesticides (or scrubbing nonorganic produce before eating).
Smoking, drinking in pregnancy causes of ADHD.
Fetal exposure to alcohol and autism tobacco is thought to play a role in ADHD. Children exposed to tobacco smoke prenatally are 2.4 times as likely to have ADHD as those who attention deficit disorder are not what causes ADHD, research suggests.
"Fetuses exposed to alcohol can develop fetal alcohol effects or fetal alcohol syndrome,what causes ADHD and the prominent features for autism both are the symptoms you see in ADHD," says Mark L. Ulrich, MD, chief of the section of developmental and behavioral pediatrics at the University of Oklahoma Health Sciences Center, in Oklahoma City attention deficit disorder.
Lead exposure attention deficit disorder .
Lead, a neurotic what causes ADHD, has been attention deficit disorder removed from most homes and schools, but traces of it are still everywhere attention deficit disorder . A 2009 study found that children with ADHD tend to have higher blood-lead levels than other kids.
"Lead can be toxic to what causes ADHD developing brain tissue and may have sustained effects on the behavior of children exposed to these substances at early ages," says Levitt, who practices under the supervision of Richard Goldberg,attention deficit disorder PhD autism. "Still, it is unlikely that such exposure accounts for differences in brain development in the vast majority of children and adolescents with ADHD."
Food additives
Many European countries have banned certain preservatives after research linked hyperactivity in young children to food attention deficit disorder with mixtures of some artificial food colors and the preservative, sodium benzoate.
What causes ADHD
The FDA says food additives attention deficit disorder are safe when used "properly," and most additives aren't required to be clearly labeled on packaging. Experts think only a small number of children will benefit from avoiding brightly colored processed foods, which tend to have more autism additives what causes ADHD.
Autism "Consult with your child's what causes ADHD doctor before putting your child on a particular diet," says Levitt. Reducing consumption of these additives may or may not help hyperactive behavior; many factors play a role in ADHD.
Sugar
Parents often blame sugar for a child's hyperactive what causes ADHD behavior, but it's time to stop.
"The overwhelming number of studies have not been able to demonstrate behavior changes due to sugar consumption in children,what causes ADHD" says Dr. Ulrich.
A study in the Journal of Abnormal Child Psychology found that mothers who thought their children were given sugar rated their children's what causes ADHD behavior as more attention deficit disorder hyperactive than mothers who were told their children were given a sugar substitute—regardless of whether their children actually consumed real sugar.
Limit sugar if you're concerned about calorie what causes ADHD consumption or dental cavities, not because of ADHD.
What causes ADHD
TV or video games
There's no proof that too much TV or video-game time causes ADHD, although research has found that school- and college-age what causes ADHD students who spent more time in front of a screen had more attention problems than those who did not.
In theory, the constant stimulation what causes ADHD of TV and video games may make it harder for kids to pay attention. But experts emphasize that screen time alone can't explain ADHD. "There is an association between (ADHD and) the number of hours young attention deficit disorder children watch TV or play video games, but more study is required to determine if it is a causal relation or it's because children with ADHD gravitate more toward those activities," says Dr. Ulrich what causes ADHD.
Bad parenting
ADHD symptoms can be confused with rebellious or bad behavior, so it's not uncommon to try to blame the parents for a child's conduct. But what causes ADHD according to the National Resource Center on ADHD, there's no strong evidence that parenting style contributes to ADHD.
What causes ADHD
"While it's true that parenting style and social circumstances may aggravate ADHD behaviors, parental style is not the cause of ADHD," says Levitt, what causes ADHD who says parents who set consistent behavioral limits, use reward and consequence behavior tools, and provide a clear set of expectations can help reduce ADHD symptoms.
On the other hand, what causes ADHD a stressful home environment or parents who refuse to accept ADHD as a diagnosed condition can make the symptoms worse.
Brain injury
"Brain injury what causes ADHD that results from a serious blow to the head, a brain tumor, a stroke, or disease can cause problems with inattention and poor regulation of motor activity and impulses," says Levitt.
And according to the National Institute of Mental Health (IMHO), children who have suffered certain types of brain trauma may show symptoms similar to ADHD. But because only a small portion of children with ADHD have suffered a traumatic brain injury, it's not considered a major risk factor.
Diet what causes ADHD
Although it was once popularly believed that food allergies or sensitivities cause ADHD, the research so far has what causes ADHD been unable to support the idea that diet plays a significant role in ADHD, Levitt says.
Still, certain dietary components may affect behavior, and a recent Australian study suggested that adolescents with diets high in fat, refined sugar, attention deficit disorder and sodium were two times as likely to be diagnosed with ADHD as other kids. Additional studies have also linked diets deficient in omega-3 fatty acids, which are important for brain development and function, to ADHD symptoms.
Genes
The evidence strongly suggests that ADHD is passed down from parents, not parenting style.
"There is a very strong heritability to ADHD," affirms Smith. "It may be one of the most heritable psychiatric disorders." In fact, a child with ADHD is four times as likely attention deficit disorder to have had a relative what causes ADHD who was also diagnosed with ADHD, and results from studies of multiple twins indicate that ADHD often runs in families.
Ongoing research is looking to pinpoint the genes responsible for ADHD. A new study by scientists at Cardiff University in Wales found that children with ADHD are more likely to have missing or duplicated segments of DNA.
Over diagnosis what causes ADHD
Because there's no objective ADHD test, parents, doctors, and what causes ADHD educators continue to debate over whether ADHD is over diagnosed.
Some say doctors are too quick to diagnose a child's behavioral problems as ADHD without considering other possible causes. North Carolina State University researchers found that children who are several months younger than their peers could be mistakenly diagnosed with ADHD when, in fact, they are just less mature than their classmates.
Nonetheless, according to Dr. Ulrich, "most of the evidence is that ADHD is under diagnosed and under treated."
Chemical exposure what causes ADHD
While smoking, alcohol, and pesticides may be a problem, researchers are looking at other toxins too.
What causes ADHD for instance, Boston what causes ADHD University attention deficit disorder School of Public Health researchers found a link between polyglot chemicals (PCs)—industrial compounds widely used in products like stain-resistance coatings and food packaging—and ADHD. Phthalates—found in items like toys, food packaging, and cosmetics what causes ADHD—have also been linked to ADHD.
what causes ADHD
But as with many factors, the evidence only what causes ADHD points to a correlation and can't prove that these chemicals contribute to ADHD.
Will eliminating dye-containing foods from a child's diet help ADHD? Experts say there's not enough evidence to recommend this action, although a small subset of children may benefit what causes ADHD. Here's a list of additives that may aggravate attention problems what causes ADHD, although none (with the exception of Yellow No. 5) has been studied alone in humans what causes ADHD.
