Answer:
When was sjögren syndrome first identified?
The disease was described in 1933 by Henrik Sjögren, after whom it is named; however, a number of earlier descriptions of people with the symptoms exist.[3] Between 0.2% and 1.2% of the population are affected, with half having the primary form and half the secondary form.[7] Females are affected about ten times as often as males and it commonly begins in middle age;[2][3] however, anyone can be affected.[2] Among those without other autoimmune disorders, life expectancy is unchanged.[6]
