Identify coma, veg state, min. conscious state, & akinetic mutism Flashcards
State of unarousable unresponsiveness
coma
Pathology in anterior or mesial portions of frontal lobe
akinetic mutism
Recovery is unlikely when it persists longer than 3 months after nontraumatic injury and longer than 12 months after truama.
vegetative state
Persons show a degree of awareness/responsiveness
minimally conscious state
Usually bed-bound, incontinent, and require tube feeding
minimally conscious state
no purposeful behavior
vegetative state
voluntary behavior is absent; eyes remain closed
coma
no purposeful behavior
vegetative state
much more common than a vegetative state
minimally conscious state
“abulia” - diminished motivation; when motivation is severely diminished, it can result in this.
akinetic mutism
sleep/wake cycles are usually preserved
vegetative state
muteness is consistent w/a severely reduced level of arousal & cognition; does not interact meaningfully with environment.
vegetative state
absence of sleep/wake cycles on EEG
coma
usually secondary to TBI and vascular events.
coma
can be occur w/metabolic disorders & severe dementia
vegetative state
can be caused from severe TBI, anoxia, drug toxicity, Wernicke’s encephalopathy, Alzheimer’s, and anencephaly.
vegetative state
reflects failure of the RAS, cortex, and absence of functions above brainstem level.
coma
when present for an extended time, may occur permanently.
vegetative state
After TBI, coma occurs, and then this happens.
vegetative state
speech is brief, delayed, aphonic, whispered, reduced in loudness/monotonic, with unelaborated content that is concrete and literal (but not telegraphic).
akinetic mutism
