Abstract

Background: Neurofeedback records hidden physiological reactions in human brain and brain waves that influence functional and behavioral status every moment. Concentration is a method in which the one educates his/her mind for more useful approach. The purpose of present research is to compare the concentration extent of people with a history of methamphetamine consumption with normal people with the help of neurofeedback via measuring brain waves. Material and Method: Present research is a clinical trial in which 40 persons were divided into two control and experimental groups. Each group consisted of 20 persons. Brain information was recorded in Cz and Fz zones by neurofeedback devices. We used Stroop’s color – word test to assess the studied concentration. We analyzed the statistical data via SPSS software, Version 16. Results: Obtained results show that people with a history of Methamphetamine abuse have lower concentration relative to healthy people. This proportion observed after using neurofeedback device too. In addition, the ratio of theta waves to Beta waves has meaningful increased in Fz and Cz zones after using neurofeedback in two control and experimental groups. Conclusion: According to obtained results, we can note that use of neurofeedback can be very effective to increase concentration in people with Methamphetamine abuse and healthy people. It is suggested to conduct more research in this field. © 2017, Indian Journal of Forensic Medicine and Toxicology. All rights reserved.
