Electroencephalograms (EEG)
|
Electroencephalogram (EEG) is one of the oldest neurological tests being performed today.
It is used on patients who exhibit everything from seizure disorders to headaches, and even to verity death.
Computerization has been a reliable diagnostic tool, providing the opportunity to obtain wave forms and latencies that can be readily measured for nerve pathway assessment.
EEG is the recording of electrical activity along the scalp produced by the firing of neurons within the brain.
In clinical contexts, EEG refers to the recording of the brain's spontaneous electrical activity over a short period of time, usually 20-40 minutes, as recorded from multiple electrodes placed on the scalp.

Brainstem Auditory Evoked Potentials (BSEP)
An Evoked Potential is an electrical manifestation of the brain's reception of a response to an external stimulus.
Most evoked potentials cannot be seen in a routine EEG recording.
BSEP uses an auditory stimulus to evoke a response in the brainstem region.
It is utilized in patients suffering of dizziness or problems with balance.
This test examines the integrity of the brainstem auditory and vestibular system.
It helps to sort out whether dizziness, ringing in the ears and spinning sensation (vertigo) is coming from a problem within the brain (as in a small stroke or head injury) or from the outer or inner part of the ear.
This test consists of a series of clicks you will hear while wearing headphones - similar to audiology testing with a similar set of electrodes on your head attached to an amplifier of a specialized neurology machine.
