The classic forms of GBS and MFS and their subtypes constitute the GBS spectrum and overlapping syndromes, which share common clinical features, including a history of previous infection, a single-phase course, symmetry, cranial or limbs weakness, CSF albumin cell separation (high protein and normal cell count), AGAbs, and evidence of demyelinating neuropathy neurophysiology. Here, ALB is linked to Guillain-Barre syndrome.
