Vagus Nerve
The tenth cranial nerve that plays a key role in the parasympathetic nervous system. It regulates heart rate, digestion, and social engagement, and is central to the polyvagal theory.
Overview
The vagus nerve is a key nerve that regulates many body functions and is central to understanding nervous system regulation in ADHD.
Detailed Description
The vagus nerve is the longest cranial nerve, connecting the brain to many organs. It plays crucial roles in regulating heart rate, digestion, and social engagement. It's central to polyvagal theory, which describes how different branches of the vagus nerve (ventral and dorsal) respond to safety and threat. Understanding the vagus nerve helps explain connections between stress, emotions, and physical symptoms in ADHD.
How This Relates to ADHD
The vagus nerve's role in nervous system regulation helps explain many ADHD experiences, particularly around stress responses and emotional regulation.
Treatment and Management
Vagus nerve stimulation techniques (like specific breathing exercises, humming, or cold exposure) can support better nervous system regulation.
