Abstract Neurophysiological studies are not well understood in different pediatric diseases. We aim to spotlight the relative importance of neurophysiological studies in different pediatric diseases in correlation with clinical findings regardless there is neurological affection or not. Neurophysiological studies are considered as part of clinical examination. EEG & EMG abnormalities may be seen in many diseases inspite that the primary disease affects systems other than the neurological system, secondary neurological affection occurs as a complication of the primary disease. The electroencephalogram (EEG) is the depiction of the electrical activity occurring at the surface of the brain. This activity appears on the screen of the EEG machine as waveforms of varying frequency and amplitude measured in voltage (specifically microvoltages). Electrodiagnostic (EDX) studies play a key role in the evaluation of patients with neuromuscular disorders. Among these studies are nerve conduction studies (NCSs), repetitive nerve stimulation, late responses, blink reflexes, and needle electromyography (EMG), in addition to a variety of other specialized examinations. NCSs and needle EMG form the core of the EDX study. These studies are performed first and usually yield the greatest diagnostic value.
