Comas can last from several days to several weeks. In more severe cases a coma may last for over five weeks, while some have lasted as long as several years. After this time, some patients gradually come out of the coma, some progress to a vegetative state, and others die.

Is there any brain activity when a person is in a coma?

The individual in the vegetative state has a lot more lower-brain function, and a bit more upper brain-stem function, than a patient in deep coma. In either case, the patient is considered legally alive. Patients in coma will have these signs; patients who suffer brain death will not.

What is the longest time a person has been in a coma?

What are the signs of going into a coma?

The signs and symptoms of a coma commonly include:

  • Closed eyes.
  • Depressed brainstem reflexes, such as pupils not responding to light.
  • No responses of limbs, except for reflex movements.
  • No response to painful stimuli, except for reflex movements.
  • Irregular breathing.
  • Can Coma be treated?

    Treatment varies, depending on the cause of the coma. A procedure or medications to relieve pressure on the brain due to brain swelling may be needed. If the coma is the result of drug overdose, doctors will give medications to treat the condition.

A coma rarely lasts more than a few weeks, but some may last years.

    What are the different types of coma?

    Types of coma can include:

  • Toxic-metabolic encephalopathy.
  • Anoxic brain injury.
  • Persistent vegetative state.
  • Locked-in syndrome.
  • Brain death.
  • Medically induced: This type of temporary coma, or deep state of unconsciousness, is used to protect the brain from swelling after an injury.
  • What part of the brain is affected in a coma?

    A coma may be caused by many different things, but ultimately a coma occurs when the part of the brain, called the reticular activating system, which controls arousal, and the cerebrum on the upper part of the brain, is not functioning properly.

    What is coma in optics?

    In optics (especially telescopes), the coma, or comatic aberration, in an optical system refers to aberration inherent to certain optical designs or due to imperfection in the lens or other components that results in off-axis point sources such as stars appearing distorted, appearing to have a tail (coma) like a comet.

    What does it mean to be in a vegetative state?

    A vegetative state is absence of responsiveness and awareness due to overwhelming dysfunction of the cerebral hemispheres, with sufficient sparing of the diencephalon and brain stem to preserve autonomic and motor reflexes and sleep-wake cycles.

    How does a life support machine work?

    When most people talk about a person being on life support, they’re usually talking about a ventilator, which is a machine that helps someone breathe. A ventilator (or respirator) keeps oxygen flowing throughout the body by pushing air into the lungs.
