| Summary: | Aya Sato,1 Shuntaro Itagaki,1 Takashi Ohnishi,2 Yusuke Osakabe,1 Hiroshi Hoshino,1 Kazuko Kanno,1 Ken Suzutani,1 Tomohiro Wada,1 Itaru Miura,1 Hirooki Yabe1 1Department of Neuropsychiatry, Fukushima Medical University, Fukushima, Japan; 2Medical Affairs Division, Janssen Pharmaceutical K.K, Tokyo, JapanCorrespondence: Aya Sato, Department of Neuropsychiatry, Fukushima Medical University, Hikarigaoka 1, Fukushima, 960-1295, Japan, Tel +81-24-547-1331, Fax +81-24-548-6735, Email ayasato12190629@gmail.comObjective: The mismatch negativity (MMN) reflects automatic cognitive function in response to auditory stimulation. The MMN to duration deviant (d-MMN) amplitude is known to be lower in children with autism spectrum disorder (ASD) than in healthy controls (HCs). Moreover, the d-MMN is known to be a trait maker of schizophrenia because it is unaffected by the duration of illness. This study aimed to identify robust tools to distinguish adults with ASD from HCs by measuring the d-MMN.Methods: Fifteen adults with ASD (age range, 20– 40 years) and 20 HCs were compared. After excluding patients with a low intelligence quotient, those using central nervous system stimulants, and those with excessive alcohol consumption, we conducted an auditory oddball task to measure the d-MMN.Results: Compared with HCs, the patients with ASD showed significantly shorter d-MMN latencies for Fz and Cz.Conclusion: The present findings suggest that the automatic cognitive function indicated by MMN amplitude might be improved by growth. Alternatively, the hypersensitivity indicated by d-MMN latencies suggests that it could persist into adulthood.Significance: The d-MMN latency was shortened in patients with ASD compared with HCs. We believe that this is the first report to reveal that hypersensitivity in ASD as reflected by a shortened d-MMN latency should be maintained, even in adults.Keywords: event-related potential, mismatch negativity, autism spectrum disorder, developmental disorder |
