Multimodal temporal dissociation in anti-GABA A receptor encephalitis: functional recovery precedes structural resolution-a case report

Anti-γ-aminobutyric acid A receptor (GABA A receptor) encephalitis is a rare but severe subtype of autoimmune encephalitis (AE), typically characterized by refractory seizures and rapidly progressive neurological dysfunction. Although structural abnormalities on magnetic resonance imaging (MRI) are frequently observed, the temporal relationships among clinical manifestations, electrophysiological changes, immune...

This single case report is too preliminary to change clinical practice, but it suggests that functional recovery metrics may not align with imaging resolution in anti-GABA-A receptor encephalitis — clinicians should not rely solely on MRI normalisation to gauge treatment success.

The dissociation between functional and structural recovery challenges the assumption that imaging normalisation is required before stepping down treatment or declaring recovery in autoimmune encephalitis.

1. 01Single case report of anti-GABA-A receptor encephalitis with multimodal temporal dissociation.
2. 02Functional recovery was documented before structural (imaging) resolution — an unusual temporal sequence.
3. 03Published in Frontiers in Immunology; evidence level is a single case report (Oxford CEBM level 4).
4. 04Finding has indirect relevance to audiologists managing patients with autoimmune-related auditory dysfunction.
5. 05Results cannot be generalised without larger studies replicating the dissociation pattern.
