Neurophysiology involves a combination of complementary techniques, including carotid-vertebral and trans-cranial Doppler ultrasound, electro-encephalography (EEG) and electro-neuromyography (ENMG).

These are valuable tools that are indispensable in standard treatment, as they contribute to the confirmation or exclusion of various diagnostic hypotheses. They also make it possible to monitor numerous disorders and to assess their response to treatment.

Their effectiveness is highly dependent upon the initial indication and the question asked, which will require the opinion of a specialist in the first instance. Accordingly, results must always be incorporated and interpreted in the overall clinical context, in the absence of which they would lose much of their specificity.
