Methamphetamine (mAMPH) is an addictive drug that produces memory and recall impairments in humans. Animals subjected to a binge mAMPH dosing regimen that damages brain dopamine and serotonin terminals show impairments in an object recognition (OR) task. Earlier research demonstrated that preceding a single-day mAMPH binge regimen with several days of increasing mAMPH doses greatly attenuates its neurotoxicity in rats. The escalating dose (ED) paradigm appears to mimic the human pattern of escalating drug intake. The current aim was to test whether an ED plus binge mAMPH regimen produces OR impairments. In addition to its translational value, this experiment helps address whether monoaminergic neurotoxicity accounts for OR impairments seen after mAMPH administration. To further address this issue, a separate experiment investigated both OR impairments and monoamine transporter integrity in groups of rats treated with a range of mAMPH doses during a single day. An ED mAMPH regimen attenuated the acute hyperthermic response to the subsequent mAMPH binge and prevented the OR impairments and reductions in 125 IRTI-55 binding to monoamine transporters in striatum, hippocampus (HC), and perirhinal cortex (pRh) that otherwise occur 1 week after the mAMPH binge. Single-day mAMPH regimens (4 x 1mg/kg to 4 x 4 mg/kg, s.c.) dose-dependently produced acute hyperthermia and, 1 week post-mAMPH, produced dose-dependent impairments in OR and reductions in monoamine transporter binding. The OR impairments of single-day mAMPH-treated rats correlated with monoaminergic transporter loss in ventral caudate-putamen, HC, and pRh. In aggregate, these findings suggest a correspondence between mAMPH-induced monoaminergic injury and the resulting OR deficits.
