Term
What is required to determine LOC
Definition

normal arousal AND full cognition

Term

    • Lethargy
Definition

      • severe drowsiness where the patient can be aroused by moderate stimuli and then drift back to sleep.

 

Term

o    Obtundation

Definition

is a state similar to lethargy in which the patient has a lessened interest in the environment, slowed responses to stimulation, and tends to sleep more than normal with drowsiness in between sleep states.
