Guillain-Barr Syndrome (GBS) is an autoimmune disorder that affects the peripheral nervous system, often leading to muscle weakness and acute paralysis. The body's immune system mistakenly attacks the myelin sheath that surrounds and protects nerve fibers, resulting in slower nerve signaling and, in some cases, damage to the nerves themselves.

The primary symptom of GBS is progressive muscle weakness, which can lead to temporary or, in rare cases, permanent paralysis. This condition typically begins in the legs and can ascend to affect the upper body and respiratory muscles, sometimes making respiratory support necessary.

The other options do not align with the symptoms associated with GBS. Increased sensory perception, enhanced cognitive functions, or improved motor skills are not characteristics of this syndrome. Instead, individuals with GBS often experience sensory disturbances, such as tingling or a loss of sensation, but not an increase in sensory perception. Cognitive functions typically remain intact, and motor skills are impaired rather than improved. Thus, the outcome of temporary or permanent paralysis captures the essence of what GBS can result in for affected individuals.
