EEG: Coma and Brain Death
|
See more in Health Science
You are given the definition of different coma types, posturing, diseases, and alterations of conciousness.
Topics of this game:
- disease, damage, or malfunction of the brain
- disoriented to place or time
- severe confusion, hallucinations
- severe drowsiness, aroused but quickly to sleep
- similar to lethargy; slowed response to stimuli; drowsy between stages
- "Semi-coma"; arousal to repeated/ vigorous stimuli, mumbles, hard to follow commands
- damage to cerebral hemispheres, internal capsule, thalamus, and possible midbrain
- damage to brainstem; lesions to cerebellum, midbrain, or upper pons
- rare; mainly in kids; spasms of axial muscles; seen with decerebrate; signs of reduced brain function or injury to nervous system
- diffuse or anterior dominant; non-reactive; poor prognosis; transitional pattern to low voltage, burst suppression, and ECI
- similar to alpha coma; brief suppression, very poor prognosis, anterior dominant
- diffuse slow with spindle activity; V-waves and K-complexes seen; better prognosis when K-complexes present
- Widespread beta; seen following overdose; seen with sedation
- Widespread delta; better prognosis when high voltage with reactivity
- No activity over 2 microvolts; need at least 30 minutes of recording
