EEG, Ambulatory EEG and Ambulatory EEG with video
Synapse provides routine and ambulatory services at private practices and at patient homes for both adults and children. This “electrical activity brain test” is in some ways comparable to MRI. While MRI snaps pictures of the brain, EEG records a movie of brain activity to tell whether the patient has symptoms and if so, where do they occur and how often.This test helps to diagnose number of disorders such as epilepsy or syncope and allows the physician to provide the patient with the right treatment. Ambulatory EEG test is painless and allows the patient to remain at home for the duration of the study which may last up to 72 hours.
Electromyography (EMG)
This is recording of the electrical activity generated in the muscle by inserting a thin needle into the belly of the muscle. The test may demonstrate abnormalities in the muscle itself, or in the nerves which connect to the muscle. EMG is usually done in conjunction with NCS.
Nerve Conduction Study (NCS)
Nerve Conduction testing evaluates how well a signal travel along a nerve and can help find the cause of abnormal nerve function. It is fundamental in diagnosing disorders including carpal tunnel syndrome, muscular dystrophy, myophaties, peripheral neuropathies, radiculopathies and other disorders. This test consists of placing electrodes (small discs) on the affected extremity (arm or leg) and delivering small electrical stimuli to monitor nerve responses.
Somatosensory Evoked Potentials (SSEP)
This study measures how body sensations are relayed to the brain and how the spinal cord and brain transmit information about those sensations through peripheral nerves. This test is useful in diagnosing multiple sclerosis, radiculopathies and other diseases.
Brainstem Auditory Evoked Responses (BAER)
This study tests both the ear and the brain by timing electrical waves from the brainstem an auditory stimulus. Delay in one side relative to the other suggests a lesion in the ear or the brainstem. Such delay are common disorders such as multiple sclerosis, acoustic neuroma, brainstem stroke, brainstem degenerative disorders.
Visual Evoked Potentials (VEP)
This test evaluates the function of the visual pathway from the retina to the brain’s occipital cortex (brain’s vision center). It is very useful in determining diseases such as multiple sclerosis and optic neuritis.
