Diagnostic and Treatment Procedures
An electromyogram (EMG) measures the electrical activity of muscles at rest and during contraction. An EMG helps find diseases that damage muscle tissue, nerves or the junctions between nerve and muscle. It is used to find the cause of weakness, paralysis or muscle twitching.
Nerve Conduction Studies
Nerve conduction studies measure how well and how fast the nerves can send electrical signals. A nerve conduction study is used to find damage to the peripheral nervous system, which includes all the nerves that lead away from the brain and spinal cord and the smaller nerves that branch out from those nerves. Our neurologists often use this test to diagnose nerve problems such as carpal tunnel syndrome or peripheral neuropathy.
The EEG records the brain’s continuous electrical activity through electrodes attached to the scalp, helping diagnose structural disease of the brain and seizures, fainting or blacking out. It is a painless procedure. To prepare for the test, do not drink any products with caffeine or consume alcohol. Arrive with clean, dry hair without hair spray or hair products.
An ambulatory EEG allows an extended recording of activity in your brain. Unlike the EEG performed in our office, the extended recording has the ability to record continuously for up to 72 hours and is done in your home during normal activities. This may be ordered to confirm an epilepsy diagnosis or seizure and evaluate nocturnal or sleep-related events, or syncope, a sudden and temporary loss of consciousness.
Vagus Nerve Stimulation (VNS)
VNS is a device used to treat epilepsy. A pacemaker-like device is implanted to generate pulses of electricity at regular intervals which helps to reduce seizure frequency and intensity. The device can also be activated “on demand” to help with seizures when they occur. The VNS is used in patients with more difficult to control epilepsy in addition to standard medication therapies.
Your neurologist may order a carotid ultrasound for conditions such as carotoid bruit, stroke, transient ischemic attack, altered mental status, syncope or incoordination of limbs. The ultrasound is a non-invasive way to view blood flow to the brain.
Botulin Toxin Therapy
Botox, Xeomin, Myobloc, Dysport are administered by injection to treat FDA approved indications such as blepharospasm, cervical dystonia, chronic migraine, severe hyperhidrosis, strabismus, and upper limb spasticity. In most cases, you will receive injections every 12 weeks.
With infusion therapy, medication is delivered intravenously. We currently infuse Tysabri and Ocrevus, which are prescription medicines approved for adult patients with relapsing forms of multiple sclerosis (MS). It helps slow the worsening of disability and decrease the number of flare-ups (relapses). The Tysabri infusion takes an hour with an additional observational period and Ocrevus is approximately 4 hours and additional post infusion observation.
