Glutamatergic hyperfunctioning during alcohol withdrawal syndrome: Therapeutic perspective with zinc and magnesium

Abstract

It is known that the glutamatergic pathways are hyperfunctioning during alcohol withdrawal syndrome. It has been demonstrated that hyperfunctioning of this system causes a great damage to the superior cortical activity, the ability to concentrate and the control of impulses. Recent studies show that the cations zinc and magnesium modulate the glutamatergic function, reducing it to non-toxic levels, yet not reducing it to the point of depriving this neurotransmitter of its normal activity. New perspectives of treatment focus on the modulation of this system, having, as a result, reestablishment of impulse control abilities, damage prevention to the hippocampus and the amygdala and prevention of future relapses.
