The Pilot Study of Medical Device-Neuclare for Patients With Mild Cognitive Disorder and Early Dementia

A Prospective Pilot Study to Evaluate Efficacy and Safety of Medical Device-Neuclare in Patient With Mild Cognitive Disorder and Early Dementia

This clinical trial aims to explore the effectiveness and safety of cognitive function improvement of Neuclare, a science medical device, for patients with mild cognitive impairment and early Alzheimer's disease.
