disorders. actual, active cases of a disorder in a population at a
given point in time (a 1-year prevalence would include
everyone who experienced X during a year’s time)
o Lifetime prevalence: estimate of the number of people
who have had a particular disorder at any time in their
lives (even if they recovered).
• Incidence is the number of new cases that occur over a given
period.
o Incidence figures tend to be lower than prevalence
figures because they exclude pre-existing cases.
• Disorders can be acute (short in duration) or chronic (long in
duration)
Discuss the prevalent rates Epidemiology is the study of the distribution of diseases, disorders, or
