Hi!

Here's some information that sounds obvious that you might have been too worried to ask about, for fear of sounding stupid:

What is an EEG? And what's an MRI?

An electroencephalogram/brain wave test (EEG) is a test to detect problems in the electrical activity of the brain. How to prepare for the test, risks, what abnormalities mean.

EEG is used to help diagnose if you're having seizures and if so, what type. An EEG is also used to find the causes of confusion, and to evaluate head injuries, tumors, infections, degenerative diseases such as Alzheimer's disease, and abnormal changes in body chemistry that affect the brain.

It is also used to evaluate problems with sleep ( sleep disorders) and to investigate periods of unconsciousness. The EEG may be done to show that the brain has no activity, in the case of someone in a deep coma. It can be helpful when trying to decide if someone is brain dead.

EEG can not be used to measure intelligence.

The MRI machine makes pictures by organising and collecting the magnetic fields that naturally occur within the body. MRI pictures show the soft tissues of the body (muscles, nerves, brain, discs, ligaments etc). In many situations MRI offers unique information to help your doctor better plan your treatment and care. Above site has information on preparations for MRI, risks, people who might be harmed by MRIs
