Neurodiagnostics are diagnostic exams focused on the assessment of the nervous system - including the brain and spinal cord, central nervous system, and peripheral nervous system. This term encompasses a wide range of different tools that can be used to understand how function may be impaired by different conditions. Neurodiagnostic assessment can include electrical activity tests like electroencephalography (EEG), evoked potential testing like auditory brainstem response (ABR) or somatosensory evoked potentials (SSEP), as well as tests like nerve conduction studies and electromyography, biopsies (skin, muscle, or nerve), autonomic nervous system testing, and videonystagmography (VNG) to name a few.
