Guillain-Barré Syndrome (GBS) is a rare neurological disorder where the body's immune system mistakenly attacks the peripheral nervous system. This can lead to muscle weakness, numbness, and in severe cases, paralysis. Symptoms often start with tingling in the legs and can progress rapidly, sometimes within days. The exact cause of GBS is not fully understood, but it is often preceded by an infection, such as a respiratory or gastrointestinal illness. Most people recover from GBS, although recovery can take weeks to months, and some may experience lingering effects. Early diagnosis and treatment are crucial for better outcomes.
