What part of the brain is damaged when in a coma?

Coma is a state of unarousable unconsciousness due to dysfunction of the brain’s ascending reticular activating system (ARAS), which is responsible for arousal and the maintenance of wakefulness.

Comas are caused by damage to the brain, especially if there’s bilateral damage to the Cerebral cortex (which means damage on both sides), or damage to the reticular activating system. The reticular activating system controls arousal and awareness of the cerebral cortex.

When someone is in a coma, they cannot interact with their environment. The brain is still working, however, and The degree of brain activity varies from patient to patient. New tools for mapping brain activity have helped doctors illuminate what is happening inside the brain, which informs their treatment and care.

Coma is generally the result of damage or interference with particular structures of the brain, and its length and depth provide a strong indication of the severity of brain injury. A coma means a person is in a state of unconsciousness.

And the answer is yes. The brain is incredibly resilient and possesses the ability to repair itself through the process of neuroplasticity. This phenomenon is the reason why many brain injury survivors can make astounding recoveries.

A vegetative state occurs when the cerebrum (the part of the brain that controls thought and behavior) no longer functions, but the Hypothalamus and brain stem (the parts of the brain that control vital functions, such as sleep cycles, body temperature, breathing, blood pressure, heart rate, and consciousness) continue …

In the past, consciousness was thought to emanate from the frontal hemispheres of the brain, but current research has found that the content of consciousness mainly originates from The hindbrain.

A coma is Similar to a dream-like state Because the individual is alive but not conscious. A coma occurs when there is little-to-no brain activity. The patient is unable to respond to touch, sound, and other stimuli. It is also rare for someone in a coma to cough, sneeze, or communicate in any way.

According to many coma survivors, the unconscious experience feels Almost like a dream, at least in retrospect. One person said it was “kind of like a normal dream where you don’t have any concept of time, but things seem to be happening.” This person had “about four different dreams” in their less-than-a-week coma.

When your survivor emerges from her coma, She likely will have little or no short-term memory. She may be disoriented, agitated, angry, impulsive, or extremely emotional. She may be disinhibited, demonstrating a complete disregard for social conventions. She may act like a child.

Most comas do not last for more than two to four weeks. A patient’s potential for recovery often relates to their score on what’s known as the Glasgow Coma Scale tool, which assesses three areas: eye opening, verbal response to a command and voluntary movements.

Coma Rarely lasts more than 4 weeks. Some patients move from coma to the VS. Others may move from coma to partial consciousness. It is rare for a person with severe brain injury to move directly from coma, or the VS, to full consciousness.

The vast majority continue to be kept alive via Hydration and nutrition delivered through a feeding tube.

Brain death: Irreversible cessation of all functions of the entire brain, including the brain stem. A person who is brain dead is dead, with no chance of revival. Coma: A state of profound unresponsiveness as a result of severe illness or brain injury.

Although many people gradually recover from a coma, others enter a vegetative state or die. Some people who recover from a coma end up with major or minor disabilities. Complications can develop during a coma, including Pressure sores, urinary tract infections, blood clots in the legs and other problems.
