Lahey Clinic's Neurology Department houses a comprehensive, state-of-the-art neurophysiology laboratory. Our testing includes EEG (electroencephalography), EMG (electromyography and nerve conduction studies), sleep labs, transcranial Doppler, autonomic testing labs and quantitative sensory testing.
Physicians with subspecialty training and board certification in these specialized areas supervise the labs, and a staff of neurophysiology technologists administer tests. Upon referral from a neurologist or other physician, patients are tested for seizures, nerve/muscle diseases and brain circulation disorders. These tests are very helpful in guiding us toward an appropriate diagnosis and treatment plan for each of our patients.
Lahey Clinic's Sleep Disorders Center is fully accredited as both a clinical center and a sleep laboratory, and tests up to six patients per night for sleep apnea and other sleep-related diseases. Clinical consultations in the Departments of Neurology, Pulmonary Medicine, Otolaryngology, Psychiatry and related fields are offered by the Sleep Disorders Center, as well.
Neurophysiology Tests and Neurovascular Ultrasounds Offered
- EEG (electroencephalography): Testing of brain waves for epilepsy and other conditions is done both in outpatient and inpatient settings, the latter encompassing a long-term video-EEG monitoring unit.
- EMG (electromyography and nerve conduction studies): Evaluation of diseases of nerves and muscles, such as peripheral neuropathy and radiculopathy (pinched nerves), is performed. Quantitative sensory testing is also done for peripheral neuropathy.
- Sleep Lab: Overnight and all-day testing for sleep apnea, narcolepsy and other sleep disorders is performed.
- Autonomic Testing: Testing is performed for peripheral neuropathy and other symptoms, including fainting.
- TCD (transcranial Doppler) and carotid ultrasound: This involves ultrasound evaluation of the circulation within the brain, and is used in patients who have had a stroke.
