Traumatic brain injury-induced cognitive and histological deficits are attenuated by delayed and chronic treatment with the 5-HT1A-receptor agonist buspirone.

Data indicate that BUS has a narrow therapeutic dose response, and that 0.3 mg/kg is optimal for enhancing spatial learning and memory in this model of TBI.

The favorable neuroprotective efficacy, broad dose–response curve, and prolonged therapeutic window observed in all models strongly suggest that repinotan is a promising candidate for treating acute ischemic stroke in humans.

NMDA receptor antagonist MK-801 reduces neuronal damage and preserves learning and memory in a rat model of traumatic brain injury

Impairment in learning and memory in TBI animals could be repaired by treatment with MK-801, which could significantly inhibit the degeneration and apoptosis of neurons in damaged brain areas.

A delayed and chronic treatment regimen with the 5-HT1A receptor agonist 8-OH-DPAT after cortical impact injury facilitates motor recovery and acquisition of spatial learning

A review of the neuroprotective properties of the 5-HT1A receptor agonist repinotan HCl (BAYx3702) in ischemic stroke.

The dose- and time-dependent neuroprotective efficacy of repinotan indicates that the drug is a promising candidate for prevention of secondary brain damage in brain-injured patients suffering from acute ischemic stroke, however, the first, randomized, double blind, placebo-controlled clinical trial did not demonstrate the efficacy of the drug.

The present study supports the idea that disturbances in the function of serotonergic system in the brain following mTBI can play an important role in the regulation of depression-related behaviors.

Protective effect of MK801 in experimental brain injury.

Findings support existing evidence that pharmacological intervention with NMDA receptor antagonist after head injury may be of clinical value in the management of head-injured patients and demonstrate neuroprotective properties of MK801, as expressed in two different variables--reduced edema formation and improved neurological recovery after HT.

The neuroprotective effect of the forebrain-selective NMDA antagonist CP101,606 upon focal ischemic brain damage caused by acute subdural hematoma in the rat.

A new forebrain-selective polyamine site NMDA antagonist is evaluated in a rat subdural hematoma (SDH) model and has shown a magnitude of neuroprotection which is comparable with that seen with "first-generation" NMDA antagonists such as MK801, D-CPP-ene and CGS19755.

The results suggest that, unlike fluid percussion TBI alone, behavioral impairment may require more select intervention when deafferentation is part of the head trauma pathology.

Effect of Noncompetitive Blockade of N‐Methyl‐d‐Aspartate Receptors on the Neurochemical Sequelae of Experimental Brain Injury

The results suggest that excitatory amino acid neurotransmitters may be involved in the pathophysiological sequelae of traumatic brain injury and that noncompetitive N‐methyl‐d‐aspartate receptor antagonists may effectively attenuate some of the potentially deleterious neurochemical sequelAE of brain injury.

Glutamate antagonism during secondary deafferentation enhances cognition and axo‐dendritic integrity after traumatic brain injury

Cognitive deficits produced by head trauma involving both neuroexcitation and deafferentation can be attenuated with chronic application of glutamatergic antagonists during the period of de Afferentation injury and that this attenuation is correlated with axo‐dendritic integrity is suggested.

NMDA-receptor blockade improved the outcome assessed by the functional tests but failed to influence the morphological changes, suggesting that this behavioural test is a more sensitive indicator of outcome after mild traumatic brain injury (TBI).
