A possible cause for ADHD

Scientists may have answered what causes ADHD

The factors contributing to the cause of ADHD have not been fully established. A recent study from Korea suggests an interesting possibility relates to chemical exposure in children. The model suggests children ingest toxins while they play with their plastic toys. The toxins identified are called Phthalates (tha-ˌlāt). These are major chemicals used in manufacturing many plastics. These compounds are used in products ranging from toys, cleaning materials, plastics, personal care items, and other materials.
Recent studies suggest Phthalates are dangerous to children who have contact with the material. Some scientists are saying these chemicals can cause hormonal disruptions, birth defects, asthma, and reproductive problems in humans.
ADHD is not one specific psychiatric or neurological disorder. The disease is represented a spectrum of disorders occurring during development and causing inattention and hyper activity. Hyperactivity is defined as squeamish, inability to follow rules, talks excessively, and has trouble being quiet. Inattention is characterized by making careless mistakes, difficulty sustaining attention, distracted by extraneous stimuli, often forgetful of daily activities.
The Prevalence of ADHD is estimated to be 3 to 7% in school age children. The disorder can continue into adulthood, even though unlikely. People with this disorder tend to cope, but it still threatens certain aspects of life. Interestingly enough it tends to affect men much more then women, even though fully grown women can have ADHD. There is no medical cure for the disorder but various medication strategies are available to treat the symptoms.
Phthalates involved with plastic manufacturing have been recently linked to ADHD symptoms. These findings were published by Korean scientists alarming public health advocates phthalates. Their study measured urine phthalate concentrations along in children who were evaluated for symptoms of ADHD using teacher-reported instruments and computerized tests that measured attention and impulsive behavior and test scores. Sadly these tests are inconclusive to date. More research is needed to find results that can be replicated in other settings. This study is promising towards finding the cause and curing ADHD.
Many people are greatly alarmed by this finding and demand increased attention toward plastics in toy products. ADHD is complicated by the probable multi factorial causes.
There are several competing theories about causes of ADHD supported by scientific studies including genetic, dietary, environmental and developmental issues. There is disagreement among people interested in this problem. There is no unanimous conclusion as to what causes ADHD but Phthalates offers a new and plausible model.

  1. This is quite interesting, if not rather bleak. However, exactly how do the scientists link Phthalates to ADHD, because in the article it states that they only linked Phthalates to things other then ADHD.

  2. This is interesting. If they find the cause and eliminate it from every-day life then the problem might be solved.

  3. This is very interesting although it's puzzling. Aren't you born with ADHD? If so then how can you get ADHD by playing with toys?

  4. I agree with Scott, if a person is born with ADHD how will toys with phthalates affect the persons behavior. Also, how do we connect ADHD to phthalates?

  5. This is a really interesting topic, but i don't think that it would be humanly possible to obtain ADHD from toys, like Scott recently said.

  6. I think that it is possible because my cousin has a really bad case of adhd. As a little kid she had toys that are from china and plastic all over her room. Maybe the toys had phtalates.

  7. Its a good point you all bring up. this is the begining of many more studies to be done. Also the reseach group was rather small and not very conclusive

  8. Everything does have Phthalates, that is what Lucas said in class. He also said that you don't always need Phthalates to make toys. So then shouldn't scientists just take out Phthalates from everything?

  9. I agree with what Scott said but I also wonder what other things could be a potential cause for ADHD.

  10. How is it that toys could cause ADHD?

  11. This is interesting, but also a bit confusing. If ADHD is not a neurological disorder, than what is it? Responding to Sophie's point- do Phthalates really appear in everything, and if so, do we need them? Maybe a lot of different problems could be solved if scientists found a replacement material for phthalates that did not cause diseases and/ or complications.

  12. yeah, i agree with what other people have been saying. Can scientists find another replacement for phthalates or is it needed in these objects? Also, is this the only cause for ADHD? Children can be born with this disease who obviously did not have contact with phthalates in the womb...

  13. It would be great if they prove this information to be correct because we might be able to eliminate the chemical from toys, and end ADHD.

  14. this is a very fasinating article. but if everything has phthalates in it, then wouldn't everyone have ADHD?

  15. very, very interesting topic. I did not think you could get ADHD from toys, but this changed my mind, and was a very convincing article

  16. This article is very interesting. I think it is very hard to find what really causes ADHD because there is so many things that scientists think cause it.

  17. interesting... hopefully, they can find a way to cure it. this is a well written article, and very convincing.

  18. This is a really interesting topic, but I still am a little unclear about how phtalates affect ADHD exactly.

    ReplyDelete
  19. The article is very convincing and its a really interesting topic. I think that this is worth studying. It does sound sort of far fetched but there is a chance it could be right.

  20. This article and topic is very good, but I think you could've used a little more information to make it clearer.

  21. The phalates seem to be a very hot cause for problems in children. There could be a connection.
