Neurological Testing

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.

  • 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.

  • 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 sleep.

    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.

  • 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.

  • 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.

  • 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.

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).
