[Neuroprotective effects of magnesium on cerebral ischemia and cerebral contusion]

Neuroprotective effects of magnesium (Mg(2+)) have been shown in experimental studies by using animal models of the cerebral ischemia and cerebral contusion. We review the neuroprotective effects of Mg(2+) in the histological and behavioral studies. In the animal models of cerebral ischemia, Mg(2+) treatment reduces the infarct volume, inhibits the neuronal death, and attenuates the motor impairments. In the animal models of cerebral contusion, Mg(2+) treatment inhibits the neuronal death and edema, and attenuates not only the motor impairments but also cognitive dysfunction.
