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.
Time is the best general predictor of a chance of recovery. For example, after four months of coma caused by brain damage, the chance of partial recovery is less than 15%, and the chance of full recovery is very low. [50] The outcome for coma and vegetative state depends on the cause, location, severity and extent of neurological damage.
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.
Barbiturates reduce the metabolic rate of brain tissue, as well as the cerebral blood flow. With these reductions, the blood vessels in the brain narrow, resulting in a shrunken brain, and hence lower intracranial pressure. The hope is that, with the swelling relieved, the pressure decreases and some or all brain damage may be averted. Several ...
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 ...
Fatal strangulation typically occurs in cases of violence, accidents, and is one of two main ways that hanging causes death (alongside breaking the victim's neck). Strangling does not have to be fatal; limited or interrupted strangling is practised in erotic asphyxia , in the choking game , and is an important technique in many combat sports ...
TBI is a leading cause of death and disability around the globe [8] and presents a major worldwide social, economic, and health problem. [10] It is the number one cause of coma, [169] it plays the leading role in disability due to trauma, [76] and is the leading cause of brain damage in children and young adults. [15]
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. There's a 'Wave of Death' in Every ...
