Exploring the Relationship Between Alpha-synucleinopathy Related Non-motor Symptom and Post-op. Delirium in Elderly Patients With Spine Surgery
Aperçu de l'étude
Statut
Description détaillée
Postoperative delirium appear approximately 10-70% of patients older than 65 yrs undergoing surgery and it is strongly associated with poor surgical outcome. The clinical characteristics of postoperative delirium are fluctuating attention, visual hallucination, disorganized thought and alter sleep-wake cycles. This is quite similar to core features of α-synuclein-related cognitive disorders such as parkinson's disease dementia and dementia with lewy body. At that point, investigator thought that postoperative delirium is preclinical stage of a-synucleinopathy. In other words, a-synuclein related disorders and postoperative delirium may share an underlying neurochemical change in their pathogenesis.
investigator will recruit age 65 and older patients scheduled to perform spine surgery. The pre-operative evaluation include neurologic exam, baseline cognitive function and a-synucleinopathy related non motor symptoms through Questionnaires.

Description de la mesure |
Délai |
|---|---|---|
|
existence of anosomia
Délai: A day before operation
|
During 72hrs after spine surgery, investigator will observe occurrence of post-operative delirium, and analysis difference of anosmia symptoms before operation between 2 groups.
The cross-cultural smell identification test will be used for measure of anosmia.
investigator define anosmia as less than 4 score on the cross-cultural smell identification test.
This study is not interventional study, because measure of anosmia by smell kit will not develop post-operation delirium more.
(investigator will classify our patients into normosmia if the CCSIT score is 9 or higher, and hyposmia if the CCSIT score is 6 or less.
Patients whose CCSIT scores are 7 or 8 will be regarded as borderline.).
