Guillain–Barré syndrome (also called "GBS") is a rapid-onset muscle weakness caused by the immune system damaging the peripheral nervous system. [3] Typically, both sides of the body are involved, and the initial symptoms are changes in sensation or pain often in the back along with muscle weakness, beginning in the feet and hands, often spreading to the arms and upper body.

When a patient presents with a non-length-dependent demyelinating polyneuropathy which either develops chronically over several months or progresses over more than a month, CIDP may be diagnosed. There may be a secondary progressive course along with a progressive course that follows, or it may be relapsing and remitting.
Multifocal motor neuropathy (MMN) is a progressively worsening condition where muscles in the extremities gradually weaken.The disorder, a pure motor neuropathy syndrome, is sometimes mistaken for amyotrophic lateral sclerosis (ALS) because of the similarity in the clinical picture, especially if muscle fasciculations are present.
A CSF culture examination may yield the microorganism that caused the infection. [ 13 ] Quantitative proton magnetic resonance spectroscopy (MRS) is a noninvasive analytical technique that has been used to study metabolic changes in brain tumors, strokes, seizure disorders, Alzheimer's disease, depression, and other diseases affecting the brain.
Inflammatory demyelinating diseases (IDDs), sometimes called Idiopathic (IIDDs) due to the unknown etiology of some of them, are a heterogenous group of demyelinating diseases - conditions that cause damage to myelin, the protective sheath of nerve fibers - that occur against the background of an acute or chronic inflammatory process.
type 3, oligoclonal bands in CSF and serum with additional bands in CSF; type 4, identical oligoclonal bands in CSF and serum, type 5, monoclonal bands in CSF and serum, type 6, presence of a single band limited to the CSF. Type 2 and 3 indicate intrathecal synthesis, and the rest are considered as negative results (No MS).
Antibodies to a GM1 epitope as well as to one with the GT1a or GD3 epitope were found in different strains of Campylobacter jejuni [14] and patients with Guillain–Barré syndrome have a high occurrence of C. jejuni infection. [15] Many studies indicate that C. jejuni may be causative for a subset of some forms of neuropathies.
A spontaneous CSF leak is a rare condition, affecting at least one in 20,000 people and many more who go undiagnosed every year. On average, the condition develops at age 42, and women are twice as likely to be affected.
