History
The first attempt to establish a set of diagnostic criteria was also due to Charcot in 1868. He published what now is known as the "Charcot Triad", consisting in nystagmus, intention tremor, and telegraphic speech (scanning speech) Charcot also observed cognition changes, describing his patients as having a "marked enfeeblement of the memory" and "conceptions that formed slowly".
