[Dynamics of neuropsychiatric disorders while engaged in occupational activities]

The authors performed a comprehensive study of neuropsychic disorders developing under conditions of occupational activity during a long (up to 6 months) voyage (n = 149). The disorders were shown to change with time and get more complicated from asthenic to unmarked affective ones (of hypothymic nature). A number of biochemical, vegetative and psychological parameters were found to change over time. The disturbances showed a rapid reversibility at rest.
