摘要
The whole night EEG were polygraphically recorded and analyzed in 9 patients with infantile spasms prior to ACTH therapy. The subjects were divided into two groups, favorable and unfavorable, depending upon the response to the ACTH therapy. (1) Among the unfavorable group, the deep sleep stage was not observed; while the light sleep stage tended to dominate. (2) REM sleep period was noted less among the unfavorable than among the favorable group. REM density also tended to be lower among the unfavorable group. (3) Of the 4 unfavorable cases, 2 did not manifest REM sleep at all. Of the remaining 2, 1 had a remarkably long REM interval period. Even among the favorable cases, REM sleep tended to be short and appear frequently. (4) The period of muscle atonia during NREM sleep was markedly prolonged in all cases. (5) Body movements of both types (gross and twitch) were less frequent comparing to those of normal younger children, more remarkably in unfavorable cases. From the above findings, a disorder of the pontine reticular formation would be suggested in cases of infantile spasms. Reduction of body movements at each sleep stage might indicate abnormalities of monoamine metabolism in the brain stem of patients with this condition.
