作者采用信访的形式,对51个有专业妇女(其中内科医师16人,精神科医师8人,护士6人,其他职业19人)的69次妊娠进行随访。在21个妇女的28次妊娠中,发现有认识功能障碍如健忘、定向力障碍、精神错乱和阅读困难。作者称此为妊娠的良性脑病。据作者分析认识功能障碍的出现与下述因素无关:分娩的年龄、体重的增长、婴儿的性别和出生体重、饮酒量、吸烟、偏头痛、变态反应病史、高血压、蛋白尿、糖尿、酮尿、贫血、晨呕,抑郁或睡眠剥夺也没有关系。此外,认识功能障碍与妊娠期出现的其他症状也无关,如:嗜睡、注意力不集中、易激惹、丧失对工作的兴趣、夜间恶梦。比无认识功能障碍组明显多见。蛋白尿在无认识功能障碍组稍有增加,而贫血在有认识功能障碍组较普遍 By petition, the author followed up 69 surgeries of 51 professional women (including 16 physicians, 8 psychiatrists, 6 nurses and 19 other occupations). Among 28 pregnancies in 21 women, cognitive dysfunctions such as forgetfulness, disorientation, delirium and dyslexia were found. The authors call this benign encephalopathy of pregnancy. According to the authors’ analysis, the occurrence of dysfunction was not related to the age of delivery, weight gain, infant’s gender and birth weight, alcohol consumption, smoking, migraine, history of allergy, hypertension, proteinuria, diabetes, ketones Urine, anemia, morning sickness, depression or sleep deprivation also have nothing to do with it. In addition, cognitive dysfunction has nothing to do with other symptoms during pregnancy, such as: lethargy, inattention, irritability, loss of interest in work, nightmares. Obviously more common than those without cognitive dysfunction. Proteinuria slightly increased in those without cognitive impairment, while anemia was more common in those with cognitive dysfunction
