Abstract
A sample of 33 adult aphasic subjects who had received speech therapy for a period ranging from 2 months to 2 years was divided into 2 groups, those who made no progress and those who made fair to good progress in therapy. Eeg recordings for each of the subjects were made before or early in the course of the subject''s therapy. Their recordings were analyzed in terms of the background frequencies for each hemisphere and delta distribution and incidence over the left and right hemispheres. The results of the statistical analyses indicated relationships between the eeg variables and recovery. Poor progress was usual when patients exhibited abnormally slow eeg patterns. A comparison of the basic frequencies of the right hemispheres differentiated the "no progress" and "fair to good progress" groups better than those of the left hemisphere, although both were highly statistically significant. It is concluded that there is strong evidence to suggest that subjects with slow background eeg frequencies may do poorly in speech therapy, particularly if both hemispheres are involved. A left hemisphere delta focus, however, is not inconsistent with a good prognosis.
