How do doctors check for brain activity?

An electroencephalogram (EEG) is a test that detects electrical activity in your brain using small, metal discs (electrodes) attached to your scalp. Your brain cells communicate via electrical impulses and are active all the time, even when you’re asleep.

How long can you stay on life support with no brain activity?

Today, with ventilators, blood-pressure augmentation and hormones, the body of a brain-dead person could, in theory, be kept functioning for a long time, perhaps indefinitely, Greene-Chandos said.

Can a brain dead person move legs?

Those movements include “facial myokymia, transient bilateral finger tremor” as well as leg muscle movement and even pupil dilation.

How long can a brain-dead person be kept alive?

There is very little research on just how long the body of a brain-dead person can be maintained. The discussion of brain death dates back to the 1950s in France with six patients who were kept “alive” for between two and 26 days without blood flow to the brain.

What does it mean to declare someone dead of brain death?

Declaring Brain Death. Brain death means that a qualified physician, typically a neurologist, did an extensive physical examination of the patient and found that the patient meets brain death criteria. Before brain death is pronounced, three clinical criteria must be met:

How does brain death differ from other states of unconsciousness?
