The Neurophysiology Department performs diagnostic testing on the
brain. This testing assists physicians in the diagnosis of a variety
of neurological problems - ranging from common headaches and dizziness
to seizure disorders, strokes and degenerative diseases. Testing
is done on patients of all ages.
Tests performed include:
EEG
An Electroencephalogram (EEG) records the electrical activity of
the brain. This activity is recorded by 25 electrodes that are placed
on the patient’s scalp. The test is not painful and takes approximately
1 hour and 30 minutes to complete.
Long Term Video / EEG Monitoring
Long Term Video/EEG monitoring is done on patients admitted overnight
into the hospital. Continuous EEG and video are simultaneously recorded
on patients with seizure disorders or suspected seizure disorders.
Transcranial Doppler
A Transcranial Doppler is noninvasive method of analyzing blood flow
in the brain. This test uses ultrasound technology. This procedure
determines if patients have a restriction in blood flow of cerebral
arteries. A lack of sufficient blood flow increases a patient’s
risk of stroke. This test takes approximately 1 hour to complete.
Ambulatory EEG
An Ambulatory EEG is an EEG that is recorded outside
of the hospital. Patients come to the EEG laboratory and have EEG
wires applied. The
EEG data is recorded onto a portable device while the patient is
in their normal environment. Ambulatory EEGs are performed on patients
with seizure disorders or suspected seizure disorders. It takes approximately
2 hours and 30 minutes to apply electrodes and set up recording equipment.
