Modern understanding of stroke increasingly centers on the nervous system — specifically, the chronic dysregulation that underlies many stroke presentations.
The Nervous System in Stroke
The autonomic nervous system has two primary states relevant to stroke:
Sympathetic activation ('fight or flight'): When chronically activated, drives anxiety-type stroke
Parasympathetic ('rest and digest'): The recovery state — undermined by stroke
Dorsal vagal shutdown: A third state — freeze/collapse — associated with depression-type stroke
Signs of Nervous System Dysregulation in Stroke
Chronic hyperarousal (always 'on edge'), difficulty relaxing even in safe environments, and feeling perpetually exhausted despite rest.
Regulating the Nervous System for Stroke
- Breathwork: Directly activates the parasympathetic nervous system
- Cold exposure: Controlled cold activates the vagus nerve, improving stroke
- Safe social engagement: Co-regulation through trusted relationships
- Movement: Discharges sympathetic activation accumulated in stroke
