The patient's score can vary from a score of 3 (indicating severe brain injury and death) to 15 (indicating mild or no brain injury). [34] In those with deep unconsciousness, there is a risk of asphyxiation as the control over the muscles in the face and throat is diminished.
Unconsciousness may occur as the result of traumatic brain injury, brain hypoxia (inadequate oxygen, possibly due to a brain infarction or cardiac arrest), severe intoxication with drugs that depress the activity of the central nervous system (e.g., alcohol and other hypnotic or sedative drugs), severe fatigue, pain, anaesthesia, and other causes.
Brain death is used as an indicator of legal death in many jurisdictions, [6] but it is defined inconsistently and often confused by the public. [7] Various parts of the brain may keep functioning when others do not anymore, and the term "brain death" has been used to refer to various combinations.
Researchers studying the brain’s final moments have gained new insight into the “wave of death” that occurs before a brain’s activity fully flatlines. When neural activity stops, it doesn ...
A new study recorded brain waves while dying people were resuscitated to see what happens during the out-of-body experiences they later describe. Near-death experiences tied to brain activity ...
Signs of death or strong indications that a human is no longer alive are: Respiratory arrest (no breathing); Cardiac arrest (no pulse); Brain death (no neuronal activity); The heart and lungs are vital organs for human life due to their ability to properly oxygenate human blood (lungs) and distribute this blood to all vital organs (heart).
Scientists have managed to make death even scarier. According to a team of scientists in New York, the human brain is still very active after death, which means there's a chance you could actually ...
The outcome of severe cerebral hypoxia will depend on the success of damage control, amount of brain tissue deprived of oxygen, and the speed with which oxygen was restored. [citation needed] If cerebral hypoxia was localized to a specific part of the brain, brain damage will be localized to that region. A general consequence may be epilepsy ...
