The youngest children in the school class will most likely be diagnosed with a hyperactivity disorder with attention to attention, whereas in fact their relative behavioral behavior may be due to their relative immaturity, according to a study published on Wednesday.
Harvard University scientists have studied the way in which ADHD is evaluated using the advantages found in many US school systems: to enroll in the kindergarten is closed on September 1st. This means that children born in August fall under the wire, while children with birthdays in September have to wait until the next school year to enroll.
"You can certainly imagine a scenario in which two children in the class, who were different in age for almost a year, could look at them differently from the teachers or school staff who evaluated them," says Dr Anupam Jena, PhD and economist at Harvard Medical School . "The annual difference in the five-year or six-year is huge."
By examining an insurance database that covers more than 400,000 children, researchers categorize children up to the month of their birth. And report to New England Journal of Medicine finds that the youngest children in the classroom – born in August – were about 35 percent more likely to get a diagnosis of dentistry and to cure the condition.
ADHD was diagnosed in 0.8 percent of children born in August and 0.6 percent of older children born in September. National, ADHD diagnosis rates are about 5%, but this includes children from 2 to 17, while this study focuses on children aged 4 to 7 years.
Scientists did not find this difference in countries that did not implement the date of entry to September, and did not find any other medical differences among children born in August in the study.
This result is important for single children who may have been inadequately diagnosed and treated. "You want to be careful to start a child in this treatment," says Jena.
But the effect of enrollment is explained only by a small part of ADHD. For the youngest children born in August – Yena says that perhaps one in four of their diagnoses may be inappropriate.
"Teachers, counselors, directors – those individuals should be aware of these possibilities," says Jena. School staff is most likely to raise the mark for ADHD and suggest to parents to see their children seen by a pediatrician.
Jeffrey Newcorn, a psychiatrist and pediatrician who deals with ADHD and learning disorders at the Mount Sinai Medical Center in New York, says the study adds a scientific discussion about ADHD. But, he says, "I would be careful to read this as if the children were wrongly diagnosed."
It may be more likely to identify ADHD in the youngest children in their grades, he says, but it may not be just an early diagnosis that would have occurred in a year or two in any case.
Several other studies have suggested that ADHD is likely to be diagnosed among children who are among the youngest in their departments.
"The current study is convincing due to the large size of the sample and the use of actual data on diagnosis rather than a more subjective recall," psychologist Stephen Hinshaw, a longtime ADHD researcher at the University of California Berkeley, writes in an e-mail.
These results highlight the deficiencies in the identity of ADHD, writes Hinshaw in e-mail. "Indeed, many childhood issues can" look "like ADHD: trauma, overcrowded classrooms, health conditions (eg, Attack) or other psychiatric problems (eg, anxiety, depression).
The results that rely on health insurance data do not have important details.
"We do not really know much about" why "and" how "these results," says Meredith Bergey, a sociologist at the University of Villanova. It is difficult to explain how these diagnoses have arrived, based simply on the data from the insurance records.
ADHD is not a simple diagnosis as an ear infection. So, Bergey claims that it should be a consideration process. "What if the teacher is there together with his parents and doctors?" pita. This would better inform the diagnosis and make potentially important factors, such as the child's age.
