Visual evoked potentials (VEPs) of the pattern shift reversal type were determined in a representative group of 57 prisoners of war (POWs) released in 1992 from detention camps in former Yugoslavia. The parameters were correlated with the conditions in four camps (1-4). All subjects were male, with a mean age of 34.75 years (SD +/- 8.92), average length of imprisonment 192.7 days (SD +/- 77.6), mean loss of body mass during imprisonment 19.32% (SD +/- 9.54), and the average number of reported blows to the head and neck was 25.7 (SD +/- 20.3). VEPs were determined on average 290.5 days after the last craniocerebral trauma caused by blows to the head and neck (SD +/- 152.0) i.e., on average 218.5 days after release from the camp (SD +/- 164.3). Although all the 57 POWs reported being maltreated to a certain extent, 14 reported being subjected to particularly brutal forms of torture, 5 had been held in solitary confinement and 25 had lost consciousness at least once. Solitary confinement and loss of consciousness had the most significant effect on VEPs, and the altered VEP parameters correlated significantly with the craniocerebral trauma experienced, loss of body mass and the length of time since the last craniocerebral trauma until examination, and from release until examination. However, the length of imprisonment and treatment in the camps did not have a significant effect on VEP parameters. The study confirmed that under such conditions the age of the subject is a risk factor. The results of this study also confirmed that prisoners in one camp had been subjected to the worst maltreatment.
对1992年从前南斯拉夫拘留营获释的57名战俘代表进行了模式翻转视觉诱发电位（VEP）检测。这些参数与四个营地（1 - 4）的情况相关。所有受试者均为男性，平均年龄34.75岁（标准差±8.92），平均监禁时长192.7天（标准差±77.6），监禁期间平均体重减轻19.32%（标准差±9.54），头部和颈部报告的平均受打击次数为25.7次（标准差±20.3）。VEP检测平均在头部和颈部受打击导致的最后一次颅脑创伤后290.5天（标准差±152.0）进行，即平均在从营地获释后218.5天（标准差±164.3）进行。尽管所有57名战俘均报告在一定程度上遭受过虐待，但有14人报告遭受过特别残忍的酷刑形式，5人被单独监禁，25人至少昏迷过一次。单独监禁和昏迷对VEP影响最为显著，VEP参数的改变与经历的颅脑创伤、体重减轻以及从最后一次颅脑创伤至检查时、从获释至检查时的时间长度显著相关。然而，监禁时长和在营地的待遇对VEP参数没有显著影响。该研究证实，在这种情况下，受试者的年龄是一个风险因素。这项研究的结果还证实，一个营地的战俘遭受了最恶劣的虐待。
