Question

Quizplus · Accepted Answer

The neurological test that helps determine brain death is an electroencephalogram (EEG). The test measures the electrical activity of the brain and can determine if there is any brain activity present. If there is no brain activity, it is a sign of brain death. Other diagnostic tests such as CT and cerebral angiogram may show structural changes in the brain but cannot confirm brain death. Carotid duplex study is a test that evaluates blood flow to the brain and is not relevant to determining brain death.
