Lahey Hospital & Medical Center's Neurology Department houses a comprehensive, state-of-the-art neurophysiology laboratory. Our testing includes EEG (electroencephalography), EMG (electromyography and nerve conduction studies), evoked potentials, 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 Hospital & Medical Center's Sleep Disorders Center is fully accredited as both a clinical center and a sleep laboratory, and tests up to 10 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.
