Painful Déjà Vu: A Rare, Benign Variant—Coping Strategies

Déjà vu (already seen) affects 60–70% of people. Painful déjà vu adds somatic discomfort (headache, nausea, chest tightness, dread) to the familiarity sensation.

Proposed Mechanisms

• Transient medial temporal lobe (hippocampus, parahippocampal gyrus) dysfunction — familiarity circuit misfires.
• Migraine aura equivalent (cortical spreading depression).
• Temporal lobe epilepsy (TLE) — but usually with other features (automatisms, post-ictal confusion).
• Anxiety/hypervigilance amplifies interoception.

Clinical Approach

• If isolated, brief, self-limited → reassurance.
• If frequent, prolonged, or with other neurological symptoms → EEG, MRI (rule out TLE, structural lesion).
• Comorbid anxiety/migraine → treat primary condition.

Coping in the Moment

1. Grounding: 5-4-3-2-1 sensory technique.
2. Controlled breathing (4-7-8).
3. Cognitive reappraisal: "This is a brain glitch, not danger."
4. Journal: track triggers (fatigue, stress, specific places).

When to Seek Help

Weekly+ episodes, functional impairment, associated seizures, headaches, or mood changes → neurologist/epileptologist.
