What does SSEP mean in NEUROLOGY

SSEP is a non-invasive electrophysiological test that measures the electrical activity of the somatosensory nervous system, which includes the sensory receptors in the skin, the nerves that transmit sensory information to the spinal cord and brain, and the areas of the brain that process somatosensory information.

SSEP is used to evaluate the function of the somatosensory nervous system, particularly the pathways responsible for transmitting sensory information from the limbs to the brain. It is commonly used to diagnose and monitor conditions that affect the somatosensory system, such as spinal cord injury, multiple sclerosis, and Guillain-Barré syndrome.

SSEP is performed by stimulating a peripheral nerve in the arm or leg with a mild electrical impulse and recording the electrical responses generated by the somatosensory system using electrodes placed on the scalp. The responses are recorded and analyzed to assess the conduction time and amplitude of the evoked potentials.

An abnormal SSEP result may indicate damage or dysfunction in the somatosensory nervous system. The specific interpretation of abnormal results depends on the pattern and severity of the abnormalities and the clinical context.

SSEP is generally a safe and well-tolerated procedure. The electrical stimulation used is mild and typically does not cause any discomfort. However, in rare cases, it may cause temporary discomfort or skin irritation at the stimulation site.
