It has been recently established that there is a high possibility for someone who had ADHD during childhood to continue having it after that person has become an adult.
According to the Diagnostic and Statistical Manual of Mental Disorders, ADHD is defined as the attention-deficit hyperactivity disorder which manifests as a persistent feature of hyperactivity-impulsivity and lack of attention.
This disorder is found during childhood before the age of twelve with the strongest symptoms until the age of 7. However, new research from King’s College London discovered that this disorder can manifest far later than childhood. Moreover, this discovery is also related to the treatment used nowadays against ADHD.
Presently, ADHD symptoms seen in kids are the struggling to pay attention, study in classrooms and sit still. The U.S. statistics from 2011 showed that there were 6.4 million children with ADHD, meaning more than 11 percent of 4- to 17- years old kids. Plus, in the following years, until 2013, the number has increased to 43 percent.
Until now, doctors believed that ADHD is more related to boys, but the numbers show that girls might be as many as the boys. According to a study from December 2015, there was a 55 percent increase of ADHD in girls, leading researchers to a more thorough observation of this disorder.
Another previous study included 2,200 18-year-old twins in Britain. Researchers looked for any sign of ADHD during childhood and found out that in every case, the symptoms manifested at the of 5,7,10 and 12. But out of 167 participants in the study who had ADHD symptoms, 70 percent of them were perfectly healthy in childhood.
Therefore, even if ADHD din not manifest in childhood, it does not mean that this disorder cannot occur later in adulthood. It means that adults too need to receive clinical attention to prevent and detect any possible symptoms of ADHD.
This study was built on earlier research in U.K, New Zealand, and Brazil, where the scientists found that many adults who suffered from ADHD were perfectly healthy in childhood.
According to Jessica Agnew-Blais, one of the lead researchers, their study is still based on many theories because in the cases of adults having ADHD there is the possibility that this disorder was masked during childhood thanks to various factors, such as a supportive family environment. In any case, the research regarding ADHD has to continue.
