Mar 5, 2024 · Patients in a coma might have brain stem responses, spontaneous breathing and/or non-purposeful motor responses. Coma has three possible outcomes: progression to brain death, recovery of consciousness, or evolution to a state of chronically depressed consciousness, such as a vegetative state.

Feb 2, 2015 · Any serious injury to both cerebral hemispheres or the brain stem can produce coma. All causes of coma can be divided into two main categories: (1) structural (e.g. trauma, bleeding, stroke), or (2) toxic/metabolic (e.g. drug overdose, lack of oxygen).

Patients in coma may or may not progress to brain death. The brain is a very complex organ. It is the brain that controls not only an individual's thought process and voluntary movements, but it controls involuntary movements and other vital body functions.

Jun 25, 2024 · Brain death is when a medical condition like a stroke or a traumatic brain injury causes major and permanent damage to your brain. In brain death, you’re unconscious and you can’t breathe on your own. Healthcare providers follow medical criteria (guidelines) before diagnosing brain death.

Nov 7, 2017 · The shift from a deep coma to brain death—permanent cessation of all brain function—may not be immediately obvious to an untrained observer. Yet recognizing this transition from life to death is critical for families, the medical team and potential organ recipients.

Coma is caused by a severe brain injury such as a traumatic head injury, brainstem stroke, or a brain hemorrhage that affects the surrounding tissue and brain structure, as well as severe hypothermia, drug overdose, drowning, and cardiac arrest.

Feb 8, 2024 · In summary, coma is a state of profound unconsciousness with potential for recovery, brain death is the irreversible cessation of all brain activity resulting in legal and clinical death, and a vegetative state involves impaired consciousness with some preserved reflexes but without meaningful awareness or responsiveness.

Brain death and coma are both conditions that affect the functioning of the brain, but they differ in their severity and prognosis. Brain death refers to the irreversible loss of all brain functions, including the ability to breathe and maintain vital bodily functions.

In summary, a coma is a state of unconsciousness with some brain activity, while brain death is the complete cessation of brain function, and the person is considered deceased.

Feb 4, 2024 · Brain death is characterized by a complete loss of brain function and is irreversible, while coma involves reduced brain activity and offers the possibility of recovery depending on …
