They also scavenge (detoxify) peoxynitrites and reverse part of their damage including partially restoring function to receptors involved in short-term memory, mood, sleep, smell, social recognition, alertness, and brain growth, increasing the transport of glucose reducing delusions and wandering, improving neurotransmissions by decreasing the hyperphosphorylation and tau proteins, and inhibiting the influxofcalcium which kills neurons.
