Abstract
Diffuse slowing constitutes 40 % of all electroencephalographic abnormalities in psychiatric patients and thus is the most common abnormality detected the EEGs obtained from psychiatric patients (Struve 1994). Correlations have been demonstrated between the degree of slowing of the EEG and impairment of functions such as awareness, attention, memory, and comprehension (Struve and Boutros 2005). As of the writing of this chapter, there are hardly any systematic and well-controlled studies examining the clinical correlates of diffuse EEG slowing in the various psychiatric populations.
