[The present and future of neurophysiological examination]

Area of Science:

• Neuroscience
• Clinical Neurophysiology

Context:

• Routine neurophysiological examinations are crucial for diagnosing neurological disorders.
• Emerging techniques offer enhanced precision and broader applications.

Purpose:

• To review current neurophysiological examinations and discuss future advancements.
• To highlight the diagnostic utility of EEG, EP, and EMG in various neurological conditions.

Summary:

• Electroencephalography (EEG) methods like source derivation and intracranial recordings aid in pinpointing epileptic foci. Polysomnography addresses sleep disorders, while EEG topography and brain electric source analysis (BESA) assist in localizing electrical dipoles.
• Evoked potentials (EP), including ABR, SSEP, and P-VEP, are vital for diagnosing brain tumors and demyelinating diseases. Event-related potentials (ERP) are gaining traction for studying human cognition.
• Electromyography (EMG) techniques such as MUP analysis and single-fiber EMG are detailed. Evoked EMG measures nerve conduction velocity, with advanced methods like collision technique and microneurography enabling detailed nerve studies. Magnetic stimulation assesses central motor conduction time (CMCT).

Impact:

• Future neurophysiological diagnostics will integrate automated EEG support, networked systems, digital recording, and non-invasive functional mapping.
• These advancements will improve the accuracy and efficiency of diagnosing and understanding neurological and sleep disorders.
• The integration of advanced neurophysiological tools promises to revolutionize patient care and research in clinical neurophysiology.
