Depressed brain function causes

A. True Alcohol, lack of oxygen, low blood sugar and hypothermia all impair cellular function in the brain and lead to a recognizable syndrome of neurological effects.

B. False Higher critical functions depending on cortical cells are first to go, e.g. driving ability.

C. True Coma implies that cellular depression has reached the less sensitive cells in the brainstem mediating consciousness.

D. False Amplitude increases initially to give delta waves in light coma before falling later.

E. False This brainstem function is preserved until the later stages of deep coma.
