[Gougerot-Sjögren syndrome. Neurologic complications].

UNLABELLED: PERIPHERAL NERVE INVOLVEMENT: Peripheral nerve involvement is better known than central nervous system involvement. The dominant features are sensoromotor polyneuropathies or pure sensorial polyneuropathies. CENTRAL NERVOUS SYSTEM: The manifestations are polymorphous, generally presenting as encephalitis and/or focal or multifocal involvement of the spinal cord. OTHER LOCALIZATIONS: Diffuse encephalic involvement is less common: acute aseptic meningitis, intellectual deterioration. Psychiatric manifestations are also frequently observed.

THERAPEUTIC OPTIONS: Response to corticosteroid therapy or immunosuppressor therapy can be spectacular but is unpredictable.
