Eleven patients who had combat neuroses resulting from the 1973 Yom
Kippur War and complained of sleep disturbances were studied in a sleep
laboratory. Sleep-onset insomniacs, dream-interruption insomniacs, and
pseudoinsomniacs were differentiated on the basis of electrophysiologic
recordings. Compared with normal controls who actively participated in the
Yom Kippur War, patients showed significantly longer sleep latencies, lower
sleep efficiency indices, lower percentage of REM sleep, and longer REM
latencies.
