목적: Allergic rhinitis is spreading disease and has various symptoms such as rhinorrhea, nasal obstruction, sneezing, itching, affecting the quality of life. Allergic Rhinitis itself is known to decrease with age, but the importance of geriatric rhinitis of the elderly population is increasing and emerging significantly. Unlike common adult, elderly usually takes much of medicine for a long time and nasal mucosa changes depending on the age. In addition, it is known that the incidence of dementia in the elderly who suffer from rhinitis is higher than normal elderly people. As a result, we figured out of the association of the clinical characteristics and senile dementia through the past medical history, medications, allergies or not, sense of smell, nasal changes and various surveys. 방법:Conducted a retrospective study to address rhinitis symptoms presented by the patient over the age of 65, or other symptoms for people who complain of rhinitis in patients 65 years of age or older who visited the address in Kyung Hee Medical Center was a patient, such as history was a paperweight. Classified the patients according to the cause of rhinitis in each case, and each of the groups was examined according to the past history, family history, symptoms, nasal structures through the Chi-Square comparison and were analyzed using the Fisher's Exact. 결과:Out of 44 patients, AR group is 11 people, none AR patients were identified as 33 people, respectively, past medical Hx 6 people, 3 people, TNSS score 6.18, 5.69, RQLQ score 56.7, 55.4, mild cognitive impairment were 70%, 52%. In Endoscpic finding, nasal septal deviation was 8 people in AR patients (73%), none AR 21 people in the group (64%). Chronic hypertrophic rhinitis was were 8 patients (73%), 19 people (58%). APT is only 3 patients with AR patients were observed. 결론:Geriatric rhinitis patients shows a high incidence of anosmia and hyposmia and was investigated 70% mild cognitive impairment in allergic rhinitis patients comparied with 52% in none allergic rhinitis patients, which was confirmed statistically significant value. (P <0.05). This important figure shows the high risk of dementia compared with normal elderly in geriatric rhinitis patients and it means that aggressive treatment is needed to and it will improve the quality and lower the probability of life of elderly patients with cognitive impairment.
