Light reflex and oculogyration analysing system is proposed in order to diagnose the Alzheimer type dementia (DAT) objectively. 19 patients are studied, which shows that the maximum miosis ratio and miosis velocity are sensitive parameters to evaluate the severity of dementia and the changing time of internal and external rectus eye muscles is the effective index for screening of the dementia. The threshold of the changing time over 0.35 second can discriminate DAT clearly from the normal. Biofeedback trainings of the demented are executed by the objective diagnosing method, which shows improvement in MMSE, ADL score and the eye reflex parameters. The proposed method may become a safe non-pharmacological treatment of the dementia.
