case_images: EEG taken on day 2 shows frontally dominant monotonous alpha frequency activity, which is continuous and nonreactive suggesting alpha coma

case_images: On day one, it showed diffuse back ground slowing, which evolved into frontally dominant alpha frequency waves without reactivity, suggestive of "alpha coma" on day 2 [Figure 1].
case_images: EEG taken on day 3 shows sleep spindles in the range of 12-14 Hz with vertex sharp waves, and K complexes, superimposed on a background of delta and theta activity, in the unarousable patient suggesting spindle coma
