“Cannabinoids have been proposed as clinically promising neuroprotective molecules, based on their capability to normalize glutamate homeostasis, reducing excitotoxicity, to inhibit calcium influx, lowering intracellular levels and the subsequent activation of calcium-dependent destructive pathways, and to reduce the generation of reactive oxygen intermediates or to limit their toxicity, decreasing oxidative injury.
Cannabinoids are also able to decrease local inflammatory events by acting on glial processes that regulate neuronal survival, and to restore blood supply by reducing vasocontriction produced by several endothelium-derived factors.
Treatment of neurodegenerative disorders is a challenge for neuroscientists and neurologists. Unhappily, the efficacy of available medicines is still poor and there is an urgent need for novel neuroprotective agents. Cannabinoids can serve this purpose given their recognized antiexcitotoxic, antioxidant and anti-inflammatory properties.”
