The term 'state of insensibility' refers to a condition in which an individual is unable to respond to stimuli or interact with their environment. This can be caused by a variety of medical conditions, such as a COMA or STUPOR. The term 'STUPOR' is defined as a state of near-unconsciousness, characterized by a lack of response to external stimuli. COMA, on the other hand, is a deeper state of unconsciousness, in which an individual is completely unresponsive and unaware of their surroundings. Both of these states can be caused by a variety of medical conditions, including head trauma, stroke, drug overdose, and metabolic disorders.
