What Is GBS?
3. Acute Motor-Sensory Axonal Neuropathy
Acute motor-sensory axonal neuropathy (AMSAN) and acute motor axonal neuropathy (AMAN) are two very similar conditions. Acute motor axonal neuropathy tends to affect children whereas acute motor-sensory axonal neuropathy is more likely to affect adults. Patients will often experience severe and rapid sensory and motor dysfunction.
These types are less common in the United States but are more prevalent in some other nations including China, Japan, and Mexico. Approximately three-quarters of people with acute motor axonal neuropathy will test positive for campylobacter. This is a relatively common bacteria that has the potential to cause serious food poisoning, although it is usually treatable.
