A neurologist has warned that while stimulant use may temporarily increase concentration, it significantly endangers memory and long-term brain health. Dr. Hamed Amiri-Fard, a neurologist, sleep fellowship holder, and faculty member at Tehran University of Medical Sciences, explained the severe trade-offs associated with these substances.
According to a report from the Jadeh Makhsous news base, Dr. Amiri-Fard stated, “Stimulants may, in the short term, reduce the need for sleep or food, making an individual feel they have more time to study or work. However, these effects are transient and actually place the brain under abnormal pressure.”
He further elaborated on the long-term consequences, noting, “Repeated use of these substances causes the brain to gradually suffer from functional erosion. Over time, this leads to memory impairment, a reduction in genuine concentration, nutritional problems, and general physical weakness. Evidence even shows that prolonged use of some of these substances can cause parts of the brain to shrink.”
From a psychological standpoint, the neurologist emphasized that short-term users might experience restlessness, anxiety, and aggression. In the long run, this can create a foundation for more severe conditions like depression or other serious psychiatric disorders.
According to Jadeh Makhsous, Dr. Amiri-Fard concluded, “There is a misconception that these substances help with learning or concentration. In reality, brain efficiency experiences a temporary, false increase, but the cost an individual pays is very heavy. Therefore, our strong recommendation is for students and professionals involved in studying and work to utilize healthy pathways such as sufficient sleep, proper nutrition, and correct planning, not the use of drugs or stimulants.”
