At Long Island Neurology Consultants, we perform a wide range of neurological testing at our Lynbrook and Hewlett offices to help speed the diagnosis
and treatment of a variety of neurological conditions.
NEUROLOGICAL TESTING INCLUDES:
- Magnetic Resonance Imaging (MRI), a highly sensitive testing technology that uses a magnetic field and pulses of radio wave
energy to image the human body. MRI can provide different and, at times, more specific information about the nervous system and other organs
than other tests including computer tomography (CT), X-ray, and ultrasound. It’s used in the diagnosis of a variety neurological conditions
including vascular irregularities that may lead to stroke, to detect and monitor degenerative
disorders such as multiple sclerosis and to document brain injury from trauma. For

- Magnetic Resonance Angiography (MRA), another highly sensitive testing technology that uses a magnetic field and pulses of
radio wave energy to image blood vessels. Able to help identify vascular problems including arterial and venous blockages, aneurysms, arterial
malformations, as well as injuries to the blood vessel walls (dissections), MRA provides different information than other tests such as
computer tomography (CT), X-ray and ultrasound but may be used in conjunction with them. For more information on MRA and how to prepare
for it, click here.
- An Electroencephalogram (EEG) records the electrical activity of the brain. Highly sensitive monitoring equipment records
the activity through electrodes that are placed at measured intervals on the patient’s scalp. The test is not painful. The head is measured
and the electrodes are placed on the scalp with a paste-like substance. The test itself usually takes thirty to forty-five (30- 45) minutes.
The principal role of the patient is simply to remain still, relaxed and comfortable. During the test, the patient may be asked to take
repeated deep breaths (hyperventilate). This activity can help reveal different brain patterns useful for diagnosis.
In some cases you may be asked to sleep less the night before, if your physician requests to observe brain patterns that occur during
EEGs assist physicians in the diagnosis of a variety of neurological problems from common headaches and dizziness to seizure disorders,
strokes and degenerative brain diseases. For more information on EEG and how to prepare for it, click here.
- Electromyography/Nerve Conduction Velocities (EMG/NCV) uses electrical stimulation of nerves and needle insertions into various
muscles to accurately evaluate diseases of the muscle, neuromuscular function, peripheral nerves and nerve roots. Herniated discs, neuropathy,
myopathy and Myasthenia Gravis are a few of the neurological conditions that can be diagnosed by this test. For more information on EMG
and how to prepare for it, click here.
- Carotid Doppler is an ultrasound procedure to evaluate the carotid arteries in the neck that supply blood to the brain. The
exam in non-evasive and consists of the patient lying down on a bed (not enclosed in a machine.) The technologist will apply gel to a flat
probe and move the probe up and down on the neck, taking images along the way. This procedure takes approximately fifteen to thirty minutes.

- Transcranial Doppler, Embolic Screening/Vaso Reactivity Study is an ultrasound procedure to evaluate the blood vessels in
the brain. This exam is non-invasive and consists of the patient lying down on a bed. The technologist will apply gel to a small, flat
probe and will place that on the patient’s eyelids, the temple area and the back of the neck. Women may want to forego eye makeup as the
gel will remove any makeup. This procedure also takes approximately fifteen to thirty minutes.
There is no need to fast for either exam. Medications can and should be taken. They will not affect the outcome of the test. Hearing aids,
contact lenses, cataracts will not affect test results. There are no adverse effects from either of these tests. Patients will be able
to leave the lab without assistance and return to their usual activities. For more information on this exam and how to prepare for it,
- Evoked Potential, a recording of the electrical activity from the brain, spinal nerves or sensory receptors in response to
specific external stimulation. Performed in our Lynbrook office only, this test is used to help evaluate a number of different neurological
conditions including multiple sclerosis, spinal cord injuries, acoustic neuroma and optic neuritis. For more information on this exam and
how to prepare for it, click here.
- Video Electronystagmography, an assessment of dizziness and balance disorders that helps determine if symptoms are peripheral
or of central origin. There is a slight chance that you might become dizzy or nauseated for a short time during or after the assessment,
which is performed in our Lynbrook office only. If possible, you should try to have someone available to drive you home if necessary. For
more information on this exam and how to prepare for it, click here.
- Neurotrax Braincare Cognitive Testing, a computerized test to assess whether you have any cognitive impairment caused by your
medical/neurological conditions. The person being tested responds to the questions shown on the computer monitor screen by either selecting
numbers on a keyboard. For more information on this exam and how to prepare for it, click here.
Other neurological testing that may be recommended by our physicians includes: Computer Tomography (CT) scan, CT Angiography, X-Ray, Ultrasonography
and Video Electroencephalogram (V-EEG).
