Diagnostic Testing

NENA Diagnostic Services include EEG, EMG and Nerve Conduction Studies, Electronystagmography (ENG) Testing, Evoked Response Testing, Myelography, X-ray Services, PET/CT (Positron Emission Tomography), and Neuropsychological Screening.


Electroencephalography (EEG) is a test that measures electrical activity within the brain. This test may be used in the diagnosis of epilepsy and other brain disorders. Overnight video EEG telemetry is an integral part of the evaluation of patients with poorly controlled seizures by the epilepsy specialists of New England Neurological Associates. These tests are performed at the New England Epilepsy Institute, a joint project of New England Neurological Associates and Lawrence General Hospital.


Needle electromyography (EMG) and nerve conduction studies (NCS) play a key role in the evaluation of patients with a wide variety of neuromuscular disorders. Through mild electrical stimuli, these tests measure the electrical activity in muscles and the functioning of nerves. These tests assist in the diagnosis of various disorders of the nerves, muscles, and spinal cord. These include assessment of low back pain, disorders of motor control, ALS, carpal tunnel syndrome, Guillan-Barre, and Myasthenia Gravis.


New England Neurological Associates has a digital x-ray device at its RIVERWALK Lawrence location, providing patients with a convenient alternative to imaging within a hospital. The office location also assists in the more rapid diagnosis of certain conditions, since physicians can often assess the x-ray study while the patient is in the office.

Evoked Response Potential

Evoked Potential (EP) tests measure electrical activity of the brain in response to stimulation of specific nerve pathways. The test may be particularly important in the diagnosis and evaluation of multiple sclerosis (MS) as well as in the detection of other problems affecting the brain or spinal cord.
