【 摘 要 】

Introduction: The aim of this study was to investigate the effects of 12-week aerobic exercise and lavender essence on cognitive states and brain-derived neurotrophic factor (BDNF) levels of elderly with mild cognitive impairment (MCI). Methods: In this clinical study, 40 elderly whose scores for mini–mental state examination (MMSE) ranged 21 to 25 were purposively selected by simple sampling. They were randomly divided into 4 equal groups: aerobic exercise, lavender extract, aerobic-lavender. and placebo. They underwent their respective treatments for 12 weeks. The aerobic exercise consisted of 8-minute running session with intensity of 75%-85% HRR Max for the first session. One minute was added to the running span after each 2 sessions. Accordingly, the running span reached 26 minutes at the end of the 12-week exercise period. To conduct treatment with lavender, 2 drops of lavender essence were administered twice a day. Before and after the treatments, cognitive state was measured and blood samples collected to measure BDNF. Results: BDNF levels of the exercise and exercise + lavender groups increased significantly compared to those of the other 2 groups (P < 0.05). In addition, the cognitive states of the 3 intervention groups increased significantly compared to that of the placebo group (P < 0.05). Conclusion: Combination of 12-week aerobic exercise and lavender may decelerate or probably halt the progressive process of the impairment via improving the cognitive state in elderly with MCI.
