Compromiso del sistema nervioso en el síndrome de Sjõgren primario / Nervous system compromise in primary Sjogren's syndrome

Nervous system involvement in Sjõgren's syndrome (SS) is extensive in its clinical expression and can be extremely serious, nevertheless it has been poorly studied. It can involve both the peripheral nervous system and the central nervous system, while immunological and vascular mechanism have been related to its genesis. The disease is subclinical in a good number of patients and should be looked for directly. In others however, it is the first symptom.
