Charcot's triad

Jump to: navigation, search

There are two sets of Charcot's triads, both of which are sets of clinical signs relating to quite separate diseases. One pertains to multiple sclerosis while the other refers to ascending cholangitis. Charcot's triads are named for Jean-Martin Charcot (1825-1893), the French neurologist who first described these combinations of signs in relation to these diseases.

Charcot's triad 1: The combination of nystagmus, intention tremor, and scanning or staccato speech. This triad is sometimes associated with multiple sclerosis but is not, however, as previously considered by some authors, pathognomonic for multiple sclerosis. Source: whonamedit.com Website

Charcot's triad 2: The combination of jaundice; fever, usually with rigors; and right upper quadrant abdominal pain. Occurs as a result of ascending cholangitis. When the presentation also includes hypotension and mental status changes, it is known as Reynolds' pentad. Source: whonamedit.com Website
