Hypervigilance — a state of elevated threat detection that persists even in safe environments — is both a symptom and driver of dementia.
What Hypervigilance Looks Like in Dementia
- Constantly scanning the environment for threats related to dementia
- Interpreting ambiguous information as threatening
- Difficulty relaxing even when safe
- Exaggerated startle response
- Exhaustion from sustained threat monitoring
The Neurological Basis of Hypervigilance in Dementia
Hypervigilance in dementia reflects an amygdala that has been conditioned to fire easily. This is adaptive in genuinely dangerous environments but becomes a dementia driver in safe ones.
Reducing Hypervigilance in Dementia
- Safety signaling: Deliberately noticing evidence of safety in the environment
- Exposure: Gradual, safe exposure to dementia triggers reduces amygdala reactivity over time
- Somatic practices: Body-based calming directly addresses the physiological component of hypervigilance
- Trauma therapy: When hypervigilance has trauma origins, trauma-focused therapy addresses roots
