The electroencephalogram in pediatrics. The indications for use and the limitations.

Electroencephalograms normally undergo pronounced serial changes during maturation of the brain. Many physiological and nonphysiological influences may alter the EEG tracing. As regards EEG's, appraisal of cerebral function is based on comparison with normal standards of frequency, rhythm, wave configuration and amplitude, bilateral synchrony, and response to various physiological stimuli. Various abnormal EEG patterns are fairly constantly related to concomitant clinical disease.A laboratory tool which may be used to supplement clinical data but not to make a clinical diagnosis, the EEG may also sometimes be of value in helping to suggest prognosis and in helping with evaluation of a therapeutic program.

Cerebral vascular diseases; certain clinical and electroencephalographic aspects.

In a preliminary study of 52 patients with cerebral vascular disease, clinical and electroencephalographic evaluations were compared. Most of the patients were in the sixth and seventh decade of life and had had symptoms of cerebral vascular disease for over a year. Seventeen of the patients had clinical evidence of intermittent cerebral ischemia. When routine electroencephalographic techniques were used, 47 per cent of the records were within normal limits. Twenty patients with cerebral vascular disease, eight of whom had clinical cerebral vascular insufficiency, were studied during posturally induced hypotension. No activation was detected in any of these 20 patients. It would appear that other methods of activation, including tilt-table studies, and serial recordings should be further explored and evaluated in these disorders if more clinically useful information is to be gained.
