Research Shows Malfunction in Brain’s Reward Center is Associated with Symptoms of ADHD; A disease linked with reward pathway of the brain can be associated with the symptoms related to ADHD (Attention Deficiency Hyperactivity Disorder).
As per the new study, the malfunction in the pathway of the human brain interferes with the experience of people with motivation and reward. A chemical which is required in brain for standard operation of the nervous system is Dopamine.
The shortages in the reward system of the brain system can help in explicating the clinical symptoms related to ADHD, which includes reduced motivation and inattention and also the chances for the complication like obesity and drug abuse among the patients suffering from Attention Deficit Hyperactivity Disorder (ADHD) as per the researcher Nora Volknow, the director and head of the National Drug Abuse Institute who has expressed his views in the news release.
Basics About ADHD
ADHD is a psychological disorder that occurs mainly among children and could also occur in adults and it has said to affect around three to five percent of the adults in United States of America. The researchers have stated that the results could offers various new insights about the Attention Deficiency Hyperactivity disorder and the reasons behind the people affected with ADHD to opt for drug abuse and extreme obesity.
The study about this disease was released in the American Medical association journal. They made use of Positron Emission Tomography (PET) scan of the brain to calculate the dopamine markers in the brain with fifty three adults who were non-medicated with ADHD and also made a comparison with another group containing forty four adults who were healthy and did not suffer from ADHD.
The results proved that when the people suffering from ADHD were compared with healthy individuals, the people who had ADHD had loss of dopamine receptors which are the transporters in two important regions of brain that are associated with motivation and reward.
Use of Brain Stimulants to Increase Dopamine levels
This brain pathway is very important as it plays major role in motivations, reinforcement and in knowing about association of different stimuli with the rewards as per the reports of Volkow. The involvement of the pathway of the brain in ADHD helps the use of intercessions to improve the relevance and appeal of work and school tasks for improving the performance of children.
The results from the study supports the ongoing usage of the medications for stimulation, the most standard medications used for the pharmacological ADHD treatments that have shown increase in the concentrations towards cognitive tasks by increasing the dopamine levels in the brain as per the report of Volkaw. By making use of stimulant drugs to enhance level of dopamine in brain, the ADHD symptoms can be reduced and the patients can feel better.
