Stimulating the Vagus Nerve Could Slow Cognitive Decline–Here’s How
The vagus nerve acts as a highway, connecting vital organs to the brain. Mastering how to stimulate it may provide relief from stubborn conditions while fostering greater calm and resilience.
Cognitive decline doesn’t happen overnight. People can live with Alzheimer’s disease and its various stages for a decade or longer before dementia becomes severe. Consequently, interest in earlier diagnosis and interventions has grown. One focus has been the vagus nerve.
Protects the Brain
In neurodegenerative conditions, such as Alzheimer’s, inflammation speeds up neuron (brain cell) damage.The vagus nerve helps maintain healthy blood flow and oxygen to the brain. It also supports gut-brain communication. When working correctly, the vagus nerve fosters an anti-inflammatory, brain-protective milieu that could slow or prevent neurodegenerative conditions, according to Winters.
The vagus nerve is also directly involved in dorsal vagal shutdown.
Dorsal vagal shutdown is also called a “freeze” reaction. It is a survival mechanism triggered by extreme stress or threats. Although it is protective in the short term, long-term activation can disrupt brain function, contributing to cognitive difficulties.
“Many people might be familiar with the idea of freezing in response to a crisis, but fewer might understand the prolonged disconnection and withdrawal that can follow,” Megan Neff, a psychologist with a doctorate in clinical psychology, told The Epoch Times.
Dorsal vagal shutdown significantly slows down both the body and the mind, and it can show up in different ways, including physical immobility, mental fog, difficulty thinking clearly, and memory loss, according to Neff.
The vagus nerve brings the body back to calmness after stress.
Upregulates the Nervous System
Blood flow to key brain regions is important because it delivers oxygen and nutrients to the brain, which is necessary for healthy brain function.
“Patients in the early stages of cognitive decline receiving VNS often report improved memory, clarity of thought, and emotional stability,” Winters said.
In more advanced cases, although complete reversal of cognitive decline may not be achievable, VNS can help manage the symptoms of Alzheimer’s disease, such as anxiety, depression, and agitation, improving the overall quality of life for both patients and caregivers, according to Winters.
Humming, Chanting, and Singing
Neff said any technique that stimulates the vagus nerve can help improve cognitive health by improving vagus nerve activity and addressing dorsal vagal shutdown. More accessible and natural options than device-based VNS include singing, humming, and chanting, which can be practiced at home.Reconnect With the Body
Also known as “earthing,” grounding techniques are methods used to help bring your focus back to the present moment and connect with the Earth’s surface. This could include walking barefoot, sitting or lying on the ground, or immersing your hands in soil or sand.Grounding helps reconnect with the physical body. It sends signals through the vagus nerve to the brain, promoting a sense of safety and calm. This connection helps shift the body out of a shutdown state, Neff said.
Connecting your physical senses to your surroundings can also effectively stimulate the vagus nerve and improve cognitive function. This is also a form of grounding.
Beyond Symptoms
While these techniques can manage cognitive symptoms and are valuable for immediate relief, true healing often requires deeper exploration.Dorsal vagal shutdowns are frequently rooted in unresolved issues such as attachment wounds, trauma, and emotional scars, Neff said.
For example, it might be that you’re taking on too much at work, which is why your nervous system is always dysregulated. The root cause (too much work) of nervous system dysregulation must be addressed for long-term healing or stability.
If dysregulation is rooted in trauma or attachment wounds, deep healing might involve approaches such as trauma-focused therapy, exploring attachment styles, and understanding personal triggers.
“For true recovery, it’s essential to take a holistic approach to nervous system regulation,“ Neff said. ”By addressing both the symptoms and the underlying causes, we can create a more balanced and effective path to recovery.”
