[Performance and personality of patients with hypersomnia].

5 groups of patients with hypersomnia (narcolepsy, posttraumatic, psychophysiologic, idiopathic hypersomnia and circadian sleep-wake disorders) were tested with a battery of psychometric tests (FPI, MMPI, BVND, BIV, Benton, d2, WIP), visual vigilance test, polysomnography and MSLT in order to investigate the context between personality and performance. MSLT showed a range from clear pathologic to borderline sleep latencies among all groups, only patients with posttraumatic hypersomnia and narcolepsy displayed sleep onset REM. Correct results of vigilance tests correlated negatively with performance-motivation and orientation in patients with narcolepsy and posttraumatic hypersomnia, whereas there was positive correlation for patients with idiopathic hypersomnia. In patients with psychophysiologic hypersomnia performance orientation and false reactions correlate negatively. Patients with posttraumatic hypersomnia have better results on d2. Benton and vigilance tests than all other groups. Results of personality diagnosis are similar to those of healthy subjects, while patients with psychophysiologic hypersomnia are more sensible than all other groups with high social fears and the highest disposition among all groups toward somatic complaints. Patients with idiopathic hypersomnia show strong introversion and inhibition. Patients with circadian sleep-wake disorders display the most striking personality disorders, which are most probably sequelae of their strong disease-dependent impairment. The degree of personality disorder seems to be strongly dependent on the duration of the hypersomnias. The assessment of the whole set of tests can only be recommended for patients with psychophysiologic hypersomnia and circadian sleep-wake disorders, a few tests suffice to describe the other groups.
