A decisive point or time.

A turning-point; a critical moment.

The change in the symptoms of a disease that indicates recovery or death; the decisive point in any important affair.

This word has been used in various acceptations. Some mean by the crisis of a disease, when it augments or diminishes considerably, considerably, becomes transformed into another, or ceases entirely. Some have used the word to signify only the favourable changes which supervene in disease; others, for the change going on in the acme or violence of the disease. Others, again, have given this name only to a rapid and favourable change, joined to some copious evacuation or eruption; whilst others have applied the term to the symptoms that accompany such change, and not to the change itself; - thus including, under the same denomination, the critical phenomena and the crisis.
