Coma Causes Diagnosis and Treatment from a Physician’s Point of View
From the basic principles all the way to the treatment concerns when you are facing someone who is not responsive to any stimuli, coma will fascinate.
COMA = no sensation to any stimuli. So painful stimuli are often elicited to provoke a response. But… No response.
So something MUST be going down to mess up one of two areas of your brain (or both!). One of these two areas must be affected for you to be in a coma. Brainstem OR Bilateral hemispheres. So, it’s the whole supratentorial portion of your brain (an anatomical term that refers to everything brain that lives above the tentorium, a horizontal support structure in your brain); OR infratentorial. So either everything above the tentorium is a no go, or everything below the tentorium is out. Or both, of course.
The brainstem lives below the 10 Tory him. Lesions in the brainstem wiping it out can cause a coma. Those lesions can be primary, intrinsic to the brainstem; or secondary, affecting some region outside it to mess it up.
