To the Editor.—  Quantitative electroencephalography (EEG) is a field in which exciting research has been done during this past decade. Much good research has been published about its applications in psychiatric disorders. Frequency analysis (spectral analysis) and topographic mapping have been the particular techniques most often employed.All this has given rise to much excitement about potential clinical uses of quantitative EEG in the diagnosis of patients with dyslexia, dementia, depression, schizophrenia, and posttraumatic disorders. Many scientists and clinicians, however, have expressed great reservations about whether enough is known to warrant such clinical use of these tests for the care and diagnosis of individual patients. The concerns raised revolve around a lack of quality scientific studies demonstrating the sensitivity or specificity of these tests for diagnosis of neuropsychiatric disorders. This led to the formation of a committee in the American Electroencephalographic Society (AEEGS), Atlanta, to study these issues. As chairman
