| Research Abstract |
Taste disorder is a common symptom in elderly persons. The purpose of this study was to survey the prevalence and causes of taste disorder in elderly. The subjects of this study were 71 elderly persons (male N=19, female n=52) who agreed with our project, aged from 65 to 94 years old (mean=8O), in 4 homes for senior citizens. The gustatory test by means of taste disc method was carried out to them for examining their taste disorder. And we asked them detailed questions about their systemic disease, the medication and taste sensation. The results were as follows : 1) Twenty-six (36.6%) of the 71 subj ects were diagnosed with taste disorder in slight or intermediate. There is no gender difference. Particularly, in their nineties, taste disorder was significantly frequent. 2) Sixty-three (88.7%) of the 71 subjects had chronic systemic diseases than those without systemic diseases. 3) All of the 26 subjects with taste disorder had some chronic systemic diseases, in which gastroenteritis, cerebral infarction and diabetes, such diseases are considered to induce taste disorder, and hypertension were frequent. 4) Twenty-five (96.2%) of the 26 subjects with taste disorder underwent such medication as to cause taste disorder or xerostomia. The occurrence of taste disorder was significantly higher in elderly with medicatjon, particular medication for hypertention, than those without medication. 5) Only five (19.2%) of the 26 subjects with taste disorder noticed subjective sensation of their taste abnormalities. These results suggest that a detailed research of the systemic disease, cpmmon used medication and gustatory test are essential for the analysis of ilderly taste disorder.
