Coma is a state of profound unconsciousness where a person cannot be aroused. A person may recover from a coma as well as a brain injury. Brain death is the permanent loss of all functions of the brain, including the brain stem. Brain death is death.

Coma is a state of unconsciousness that occurs because the brain is injured in some way. The brain still functions and this can be seen in the tests that are performed. The person will be able to breathe on his own without the help of a respirator. The brain, in fact, may heal.

No. Coma is decrease in brain function and thee is a chance that person may regain consciousness. Brain death is irreversible loss of brain function. There is no chance of recovery after brain death.Top

Brain death results from a severe, irreversible injury to the brain. All areas of the brain are damaged and no longer function. In situations of brain death, a person cannot sustain their own life, but vital body functions may be maintained in an intensive care unit for a short period of time. This maintains circulation to the vital organs long enough to facilitate organ donation. People who experience brain death can also donate tissue.

Brain death occurs when person's brain has permanently stopped. Cardiac death is said to occur when heart stops beating. Both are legal declarations of death. Brain death does not occur as often as cardiac death.Top

A person who becomes an organ donor invariably dies following a severe brain injury. Brain damage is so extensive that the brain dies as a result of insufficient blood and oxygen. Once brain death occurs, the body will die.With the artificial support of medicine and the respirator, the organs may function for a short time. Once brain death occurs, organ donation may proceed with the consent of the donor’s family. Since organs cannot be stored, transplantation is an emergency procedure.

Brain death is the irreversible and complete cessation of all brain and brain stem function. It means there is no blood flow through the brain or brain stem and the patient has stopped responding to outside stimuli. It is considered legal death and allows a death certificate to be signed. Brain death is not the same as being in a coma, since coma patients still have brain function and respond to stimuli.

A coma is a state of deep unconsciousness where the person cannot by aroused. It is generally characterized by the absence of spontaneous eye movements, response to painful stimuli, and vocalization. Loss of consciousness typically involves injuries to the brain stem, the oldest part of the brain, which is responsible for basic life functions such as alertness, arousal, heartbeat, and breathing. A patient's degree of consciousness is often used to determine the severity of his/her brain injury.

Although some “experts” claim that individuals have brain damage or have died because of exposure to mold and especially mold toxins, there is no good science at this time to support these claims. Consequently it is prudent to minimize one’s exposure to really moldy environments. By “really moldy” we mean where there are large visible areas of mold (more than a few square feet) or the building has a “musty” odor because of hidden mold growth.
