Neurodegenerative diseases, such as Alzheimer’s disease, affect an increasing number of people, especially in developed countries, where life expectancy is constantly increasing. There are tens of millions of patients worldwide suffering from this disease. Unfortunately modern medicine does not offer an effective method of causal treatment. Current methods focus on reducing symptoms and slowing down the development of the disease. Pharmacological treatment is most commonly used for this purpose. Currently developing research direction is the use of neurostimulation techniques. The technique of stimulation of the vagus nerve has been approved by the US Food and Drug Administration for the treatment of drug-resistant epilepsy, depression and migraine pain. Current technical solutions in this field include mainly invasive methods, i.e. devices implanted in the patient. Such surgical intervention, especially implantation of a stimulation electrode, carries the risk of undesirable side effects.

The VGuard system developed by Neuromedical is a non-invasive, transdermal device used to stimulate the vagus nerve during sleep, suitable for patients with mild to moderate cognitive impairment associated with dementia and occurring in the course of Alzheimer’s disease. The device is intended for home use. Depending on the degree of dementia, the device will be used by the patient alone or with the help of a caregiver. The potential users also include institutions dealing with this type of patients, such as hospitals and nursing homes. The VGuard project is the first solution on the global market to use vagus nerve stimulation to achieve improvements in the function of the brain areas responsible for memory consolidation. The device will connect to a dedicated mobile application and collect data in the cloud. Operation will be very simple, limited to placing the device in the ear and putting on a sensor band. The technology is protected by a patent application.

In vivo research regarding the analysis of the direct and indirect stimulation of the vagus nerve on the type II hippocampal rhythm, carried out as part of the project, are innovative on a global scale. The results obtained by the Neuromedical team in cooperation with the Department of Neurobiology at the University of Łódź confirm the results of pioneering research in this field – stimulation increases, among others, levels of noradrenaline in the spinal and basal ganglia of the brain, which slows down the progression of Alzheimer’s disease. In addition, a decrease in the concentration of tau protein in cerebrospinal fluid, responsible for the progression of disease symptoms, is observed.

At the time of INNOventure investment, the project has completed the pre-clinical phase. Animal studies and first clinical studies have been carried out on 30 patients using functional magnetic resonance imaging. The INNOventure investment will finance further research and development work on animals, human research including statistical analysis of functional magnetic resonance imaging results, development of software for system control and data collection, and improvement of the ergonomics of the operational parts of the device.
