Abstract:

Although the electroencephalogram EEG is altered by many brain dysfunctions, its clinical utility has been severely limited by reliance upon visual pattern recognition and subjective interpretation. Not only is the concordance poor between electroencephalographers and the test-retest reliability low, but many changes due to more subtle dysfunctions are simply not apparent by visual inspection. Accordingly, there has been increasing interest in developing methods for objective computer extraction of quantitative features with diagnostic utility from brain electrical activity. Our laboratories have been engaged in this endeavor since 1973. Our goal has been not only to replace subjective judgements by objective quantification, but to extend the utility of electrophysiological examinations beyond their traditional role in the detection of neurological disorders to the assessment of cognitive impairments and the evaluation of psychiatric patients. In many disorders, similar behavioral symptoms may be displayed for quite different underlying patients. In many disorders, similar behavioral symptoms may be displayed for quite different underlying reasons. For example, learning disabilities may be due to motivational or psychosocial factors, or to sensory deficits or brain dysfunctions. An elderly person may display problems with recent memory because of a sense of lack of purpose or because of organic changes caused by Alzheimers disease or multiple infarcts. Depression may be a reaction to the disintegration of personal relationships or reflect inbalance in neurotransmitters. js
