请将以下段落变得更加精简，同时保留核心信息： Guillain-Barré Syndrome (GBS) is a rare disorder in which the body's immune system attacks the peripheral nerves, leading to muscle weakness and sometimes paralysis. Its cause is unknown, but it often follows an infection. GBS can affect anyone and the symptoms typically start with tingling or weakness in the extremities, and can progress over days or weeks to affect the entire body. Treatment includes plasmapheresis (plasma exchange) and intravenous immunoglobulin (IVIG), which can help reduce the severity and duration of the symptoms. Recovery can take a few weeks to a few years, and residual weaknesses may persist.

吉兰-巴雷综合征（GBS）是一种罕见的疾病，患者自身免疫系统攻击外周神经，导致肌肉无力甚至瘫痪。病因不明，但常在感染后发生。症状通常始于四肢的麻木或无力，并在数天至数周内扩散至全身。治疗包括血浆置换和静脉注射免疫球蛋白，有助于减轻症状和缩短病程。恢复期从几周到几年不等，患者可能留下持续的无力症状。
