["Railway" paranoid disorder and forced insomnia].
The relationship between forced insomnia and acute transitory exogenous psychosis named "railway paranoid" is under discussion. According to the author's data, forced insomnia precedes that psychosis in all the cases; it lasts from 2 to 5 days, being consequent on a tiresome journey. A permanent and direct relationship can be elucidated between the duration of insomnia and the depth of paranoid. Psychosis is eliminated after a deep sleep and subsequent asthenia. In experimental sleep deprivation described by some authors, the general regularities were established between psychosis in question and the status of disturbed consciousness. The conclusion is made that forced insomnia causes railway paranoid. It is of importance to stress that all attempts to discover some other psychogenic factor which would explain the exogenous structure of the given psychosis have so far ended in failure.
