Does Islamic fasting affect cognitive functions in adolescents? A systematic review

A considerable population of the Muslim community is made up of youngsters who observe fast during the month of Ramadan. There are other activities in Ramadan that the adolescents might be involved in, such as education in which one's proper cognitive activity is necessary. The current systematic review was planned to evaluate the relationship between Islamic fasting and cognitive activities. A number of studies have paid attention to the brain structure and scope of cognitive changes during fasting. Islamic fasting may affect cognitive activities such as spatial memory, visual memory and attention that play an important role in effective education. It is suggested to conduct a study with a larger sample size, using similar evaluation tools, targeting different cognitive tasks.
