Recently, a team of researchers conducted a study to gauge as to what causes attention deficit hyperactive disorder (ADHD) among kids. During the study, it was found that kids affected with ADHD had reduced level of proteins and necessary brain chemicals.

Researchers specifically noted that the deficiency of tryptophan, which helps in producing dopamine, noradrenaline and serotonin causes ADHD among kids. The findings of the study are important as they shed rays of hope to the future treatment of ADHD patients.

The study was conducted by the researchers of Orebro University, located in Sweden. A researcher of the study, Ms. Johansson was reported as saying, “This indicates that several signal substances are implicated in ADHD, and in the future this could pave the way for other drugs than those in use today”.

However, the findings of the study can’t be trusted blindly as it does have limitations. The study was conducted over a very small section of the ADHD patients. Only boys were recruited for the research. Further research over ADHD patients will take place with the aim of finding effective treatment for ADHD. People affected with ADHD often find it hard to maintain social relationships.
