Electroencephalography (EEG) 1 ENPY 1262

Upon successful completion of this course, the student will be able to:

• Define and apply common terms used to describe waveform characteristics.
• Identify state changes and associated waveforms on a normal adult, paediatric and neonatal EEG.
• Identify and describe abnormal waveforms including dysthymias, epileptiform, asymmetries, periodic and pseudo periodic patterns, and other variations from normal patterns.
• Identify common normal variants that can be seen in EEG recordings.
• Explain the principles of how an electrical signal is recorded and displayed by a digital and analogue EEG machine.
• Define EEG recording parameters including electrode properties and impedance.
• Describe the potential harmful effects of electricity, the sources of electrical hazards and how to avoid them.
• Identify common physiological and non-physiological artefacts and appropriate troubleshooting techniques.
• Describe the activation procedures used during an EEG, including normal and abnormal responses and indications and contraindications of each.
• Describe EEG generators and how EEG activity is recorded at the scalp.
• Describe techniques for achieving and obtaining cooperation from a young or difficult patient for the purpose of obtaining an optimal EEG.
• Demonstrate the clinical application of the International 10-20 System of electrode placement using CAET (Canadian Association of Electroneurophysiology Technologists) guidelines, including modification techniques.
• Calculate the duration, amplitude, and frequency of a waveform.
• Localize EEG waveforms using EEG convention, phase reversals and end-of chain techniques.
• Perform a routine digital EEG recording using CAET guidelines within a 45-minute time period demonstrating accurate measurement and electrode placement, use of appropriate settings, and troubleshooting techniques.
• Prepare a concise and complete technical interpretation/report of a normal and abnormal EEG.
• Correctly identify states of consciousness, including awake, drowsy and sleep state as well as their appropriate waveforms.
• Analyse and describe EEG normal and abnormal waveforms seen on previously and real-time recorded EEGs during assignments and reading sessions.
• Obtain a relevant patient history for an EEG.
• Obtain a relevant patient history for an EEG.
