The vagus nerve has been shown to enhance memory consolidation, the process of transferring short-term memories to long-term storage. This effect is believed to be mediated by the vagus nerve’s ability to activate the release of Noradrenaline and acetylcholine, a neurotransmitters that play a crucial role in memory formation.
Studies have demonstrated that vagus nerve stimulation can improve memory performance in both healthy individuals and those with cognitive impairments.

Studies have demonstrated that vagus nerve stimulation can improve memory performance in both healthy individuals and those with cognitive impairments. For instance, one study found that VNS enhanced verbal memory in patients with Alzheimer’s disease. In another study done in animal model, it was shown that VNS increase Tetha II brains wave activity in the Hippocampus that are related to memory consolidation processes in the brain.
The vagus nerve also influences attention, the ability to focus and selectively process information. It helps to regulate alertness and reduce distractibility, allowing for better concentration and task performance.
Research suggests that VNS can improve attention in individuals with attention deficit hyperactivity disorder (ADHD) and other conditions that affect attention span.
Auricular vagus nerve stimulation (AVNS) is a non-invasive neuromodulation technique that involves applying electrical stimulation to the concha of the ear, which is part of the outer ear and is in proximity to the auricular vagus nerve branch and provides sensory innervation to the ear canal, tragus, and skin of the auricle.
AVNS is generally considered to be safe and well-tolerated method to inervate the vagus nerve. The most common side effects are mild and temporary, such as ear pain, redness, and itching.
Results and research method
In our clinical trials we utilized various neuropsychological tests : Alzheimer’s Disease Assessment Scale-Cognitive (ADAS COG), Verbal Memory Probing, Colour trial test, Minimental State Exam (MMSE)
