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