Dr Katherine Hall suggested that Alexander, who died in Babylon in 323 B.C., suffered from a rare autoimmune disorder known as Guillain-Barré Syndrome (GBS). The conqueror exhibited strange symptoms, including fever, abdominal pain, and progressive paralysis that left him immobile but still completely sound mentally just eight days after falling ill.

Guillain-Barré (pronounced ghee-yan bar-ray) syndrome is a very rare and serious condition that affects the nerves.
It mainly affects the feet, hands and limbs, causing problems such as numbness, weakness and pain.
It can be treated and most people will eventually make a full recovery, although it can occasionally be life-threatening and some people are left with long-term problems.
Guillain-Barré syndrome affects people of all ages, but your chances of getting it increase as you get older.
