Total Score

To check your sleepiness score, total the points.

Note: Anyone who scores higher than 10 on the Epworth Scale, and especially anyone with suspected obstructive sleep apnea, should have further testing

Excessive daytime sleepiness combined with either obesity or snoring warrants further investigation with sleep study.

A key question is whether a person with excessive daytime sleepiness actually falls asleep in inappropriate situations, or merely feels tired.
