Guillain-Barré syndrome is best described as which of the following?

Guillain-Barré syndrome is an autoimmune attack that targets the peripheral nerves, leading to acute inflammatory demyelination. The hallmark is rapidly progressive, symmetric weakness that starts in the legs and ascends toward the arms and possibly the face, often with reduced or absent reflexes. This pattern reflects involvement of the peripheral nervous system rather than the brain or spinal cord. It’s not a central nervous system demyelination (that would be conditions like multiple sclerosis), nor a chronic progressive motor neuron disease (such as ALS), nor an isolated cranial neuropathy (which would affect mainly one or a few cranial nerves). Guillain-Barré typically follows an infection and can progress over days to weeks, with the potential for respiratory compromise, but it is ultimately reversible with appropriate treatment and supportive care. Diagnostic clues include albuminocytologic dissociation in cerebrospinal fluid (high protein with normal cell count) and demyelinating patterns on nerve conduction studies. Treatments such as intravenous immunoglobulin or plasmapheresis, along with careful monitoring, are used to support recovery.
