Final answer:
The pattern of weakness in Guillain-Barré syndrome starts with tingling and weakness in the affected tissues, progresses over weeks, and can lead to complete paralysis. The weakness is usually symmetrical and can affect the legs, arms, and face.
Step-by-step explanation:
The pattern of weakness noted in patients with Guillain-Barré syndrome (GBS) starts with tingling and weakness in the affected tissues. The weakness can progress over several weeks, ultimately leading to complete paralysis. The muscle weakness is usually symmetrical, affecting both sides of the body, and it may start in the legs and then spread to the arms and face. Severe cases of GBS can result in respiratory muscle weakness, requiring assistance with breathing.
