I have my great grandfather's death certificate that states he died from Locomotor Ataxy Exhaustion. Can anyone explain what this is please. He died in 1902 aged just 44. I tried Googling these words but I am still none the wiser really. It appears to be to do with the central nervous system, and the 'Exhaustion' implies he had been suffering from it for some time.
I would be very grateful for a explanation in layman terms.
