Abstract
Our experience and review of the literature reveal that Sjogren' syndrome (SS) is an important, poorly recognized cause of peripheral neuropathy. Several forms of peripheral nerve dysfunction occur in SS including trigeminal sensory neuropathy, mononeuropathy multiplex, distal sensory neuropathy, distal sensorimotor peripheral neuropathy and a pure sensory neuronopathy syndrome. Rarely, chronic relapsing inflammatory polyneuropathy and multiple cranial neuropathies appear. Clinical evidence of glandular in volvement is often minimal or absent when patients with SS develop peripheral neuropathy; and the diagnosis of the underlying condition is elusive. We review clinical and laboratory features of this disorder and suggest appropriate evaluation of patients with neuropathy and suspected SS.
