Patients with dementia show various behavioral or psychiatric symptoms, including depression, delusions, hallucinations, and apathy.1 Especially, geriatric patients diagnosed with Alzheimer's disease (AD) manifest repetitive and stereotyped behavior, resulting in stress and depression among caregivers.2 Here, we report 2 patients with dementia presenting with a repetitive verbal sound of “eo-meo-ni”, meaning “mother” in Korean, after taking risperidone. We also suggest a possible neural mechanism for this phenomenon.
