| Outline of Final Research Achievements |
Elderly people with dementia usually fall easily due to balance disorders. We reported that vestibular dysfunction due to cerebral cortex disorder could be related to balance disorders with Alzheimer's disease (AD). In this study, we attempted to induce vestibular compensation due to vestibular stimulation, which can activate the cerebrum, such as the vestibular cortex, with the intention of preventing the progress of balance disorders. We used an air caloric device to repeat vestibular stimulation in patients with AD every two weeks for six months. Their dementia symptoms progressed over the observation period; on the other hand, based on subjective symptoms and objective tests, such as electronystagmography and caloric testing, there was no meaningful indication that the balance disorder was progressing. The possibility that vestibular stimulation could delay the progression of balance disorders with AD was suggested from these results.
