Amyloidosis is not associated with neurosarcoidosis. Neurologic syndromes associated with neurosarcoidosis include aseptic meningitis, diffuse encephalopathy with vasculopathy, and seizures. The presence of seizures worsens the prognosis. In addition, a hypothalamic syndrome has been described. This includes clinical manifestations such as obesity, chronic hypernatremia, hypovolemia, and frank diabetes insipidus. Any peripheral nerve may be involved in sarcoidosis, with or without other cranial or peripheral nerve involvement.
