Evaluating and diagnosing damage to the nervous system can be
very complicated. Many of the same symptoms occur in different
combinations among the different disorders. To further
complicate the diagnostic process, many disorders do not have
definitive causes, markers, or tests. Neurological tests to
evaluate children may include: Computed tomography scan (also
called a CT or CAT scan). A diagnostic imaging procedure that
uses a combination of X-rays and computer technology to produce
horizontal, or axial, images (often called slices) of the body.
A CT scan shows detailed images of any part of the body,
including the bones, muscles, fat, and organs. CT scans are more
detailed than general X-rays. Electroencephalogram (EEG). A
procedure that records the brain's continuous, electrical
activity by means of electrodes attached to the scalp. Magnetic
resonance imaging (MRI). A diagnostic procedure that uses a

to produce detailed images of organs and st
