Aluminum, a known neurotoxin, has long been implicated in the pathogenesis of Alzheimer's disease. Its exposure is associated with impairment in the cholinergic system in the brain. In this study we investigated the behavioral effects of aluminum in rats and the possible effect of rivastigmine, a cholinesterase inhibitor, on the aluminum-induced behavioral(More)
Memantine, a noncompetitive NMDA receptor blocker, has been demonstrated to be neuroprotective against various neurotoxins. Aluminum, a well-known neurotoxin, has been suggested to be a contributing factor in Alzheimer's disease. In this study we investigated the possible effect of memantine on aluminum-induced cognitive impairment in rats. Rats were(More)
Although being a physiologically important excitatory neurotransmitter, glutamate plays a pivotal role in various neurological disorders including ischemic neurological diseases. Its level is increased during cerebral ischemia with excessive neurological stimulation causing the glutamate-induced neuronal toxicity, excitotoxicity, and this is considered the(More)
