Understanding Comas: Causes, Duration, and Diagnosis
TLDR Comas can occur due to various causes such as head trauma, brain injury, diseases, drug overdose, or stroke. Doctors use scales to determine the level of alertness and responsiveness of someone in a coma, and diagnostic tools like EEG, MRI, fMRI, and CT scan to determine the cause. Research is being done to monitor brain activity in comas and vegetative states using fMRI machines.
Timestamped Summary
00:00
Comas can happen fairly frequently, but there are rare cases where individuals can remain in a coma for an extended period of time, such as 16 or 19 years.
04:04
Comas occur when individuals are in a state of unconsciousness and do not respond to stimuli, and they can last for an extended period of time, such as 16 or 19 years.
07:18
There are different altered states of consciousness, such as a vegetative state, stupor, and locked-in syndrome, that are similar to comas but have distinct characteristics.
10:41
Comas can be caused by severe head trauma, brain injury, diseases like meningitis, drug overdose, and diabetes, but the exact mechanisms behind these causes are not fully understood.
14:40
Comas can occur gradually or suddenly, and can be caused by various factors such as head trauma, diabetes, drug overdose, or stroke, and doctors use scales to determine the level of alertness and responsiveness to determine if someone is in a coma.
17:49
Doctors use scales ranging from three to 15 to determine the level of alertness and responsiveness of someone in a coma, with three being a very deep coma and 15 being the least severe, and once stabilized, they will use various diagnostic tools such as EEG, MRI, fMRI, and CT scan to determine the cause of the coma.
20:57
Dr. Adrian Owen of Cambridge University is researching a consciousness meter for people in comas and vegetative states using fMRI machines to monitor brain activity and determine if there is more brain activity than previously thought in these states.
24:32
87% of individuals who score between 11 to 15 on the coma scale within the first 24 hours are likely to make a good recovery, while those who score a three or four are likely to either die or remain in a vegetative state.
