Evaluation of Cerogrin for Auricular Vagus Nerve Stimulation in Vascular Dementia or Vascular Mild Cognitive Impairment

This clinical trial evaluates the preliminary effectiveness and safety of Cerogrin, a medical device developed by Neurogrin Inc. for auricular vagus nerve stimulation, in patients with vascular dementia or vascular mild cognitive impairment. Given the limited availability of effective pharmacological treatments for these conditions, the study aims to assess whether Cerogrin can enhance cognitive function through non-invasive neuromodulation.

Twenty-four participants will be randomized to receive either the active Cerogrin device or a sham (non-stimulating) device. Daily use will occur at home for 30 minutes over a four-week intervention period. The full study duration, including baseline assessments and follow-up, will span up to three months. During this period, cognitive function, neural activity, and safety outcomes will be systematically evaluated. This feasibility trial represents a critical step toward expanding therapeutic options for vascular cognitive impairment.
