Background: This study examined the association between memory function and reduced olfactory and gustatory function among independent community-dwelling older adults. Methods: This cross-sectional study included 127 older adults (65.4% women). We assessed their memory, odor, and taste identification skills. Open essence (OE) test and taste strips (TS) were used to identify hyposmia (OE test ≤6) and hypogeusia (TS test ≤8), respectively. Results: Participants with severe hyposmia had significantly poorer memory functions compared to participants without severe hyposmia. After adjusting for covariates, multivariate logistic regression models revealed a significant association between immediate recognition performance and a decreased likelihood of severe hyposmia (odds ratio=0.65; 95% confidence interval 0.47–0.90). We observed no significant association between taste function and memory. Conclusion Memory function may be associated with olfactory impairment in older adults.

The case was a 77-year-old man. He had dizziness and dysphagia for 2 years, and underwent detailed screening at the internal medicine department for general malaise and bloody sputum. He was hospitalized for aspiration pneumonia due to dysphagia of unknown origin. This time, he visited a local doctor with palpitations and shortness of breath. Echocardiography indicated a left atrial tumor involving the mitral valve and arrhythmia. Emergency surgery was performed to remove the left atrial myxoma and close the patch at our hospital's cardiovascular surgery department. After the excision, swallowing function was restored, and the patient was diagnosed with postoperative Ortner's syndrome. We report a case where echocardiography was considered important as a detailed investigation of the cause of swallowing dysfunction and dizziness.
