Özet

Cognitive dysfunction is commonly observed in schizophrenic patients and the administration of antipsychotic treatments results in different outcomes. Although the typical antipsychotic treatments, such as haloperidol, appear to be unable to improve cognition dysfunction, the atypical antipsychotic drugs (quetiapine, aripiprazole and iloperidone) exert a beneficial effect. The purpose of the current study was to investigate the effects of atypical antipsychotics on olfactory memory in mice, utilizing the social transmission of food preference (STFP) tests to evaluate the effects of drugs on MK-801-induced cognitive dysfunction. Female BALB/c mice were treated with quetiapine (5 and 10 mg/kg), aripiprazole (3 and 6 mg/kg), iloperidone (0.5 and 1 mg/kg) or MK-801 (0.1 mg/kg) alone or concurrently prior to retention sessions of STFP tests. In the STFP tests, quetiapine (10 mg/kg; P<0.05), aripiprazole (3 and 6 mg/kg; P<0.01 and P<0.001, respectively), iloperidone (0.5 and 1 mg/kg; P<0.01 and P<0.001, respectively) and MK-801 (P<0.001) significantly decreased cued/total food eaten (%). Quetiapine (5 mg/kg; P<0.05) significantly increased MK-801-induced decreases in cued/total food eaten (%), while aripiprazole and iloperidone demonstrated no significant effects. The results revealed that all of the drugs disturbed olfactory memory in the naive mice; however, only quetiapine reversed MK-801-induced memory impairment in the STFP test.
