24h动态脑电图与常规脑电图在儿童癫痫检查中的诊断价值

目的观察24 h动态脑电图与常规脑电图在儿童癫痫检查中的诊断价值。方法选取2013年9月~2014年6月疑似癫痫病症的儿童64名,分别采用24 h动态脑电图检查和常规脑电图进行检查。比较两种检查方法的脑电图总异常率。结果 24 h动态脑电图监测的总异常率为93.8%（60/64）,明显高于常规脑电图的54.7%,差异有统计学意义（P〈0.05）。24 h动态脑电图监测有异常改变的60例患者中,具有儿童癫痫症状的患者为52例,在睡眠中出现症状的为16例,既在睡眠中又在清醒中发生症状的患者为36例。结论 24 h动态脑电图是诊断儿童癫痫的可靠检查方法。

24 h动态脑电图与常规脑电图在成人癫痫检查中的诊断价值及准确性分析

目的:探讨24 h动态脑电图与常规脑电图在成人癫痫检查中的诊断价值及准确性。方法:2019年1月-2020年1月收治成人癫痫患者100例,均采用常规脑电图及24 h动态脑电图检查。分析患者清醒、安静、闭目状态下常规记录以及睡眠中动态脑电图表现。结果:动态脑电图痫样波检出率明显高于常规脑电图,差异有统计学意义(P<0.05);而且随着检测次数的增加,痫样波阳性检出率明显提高。结论:24 h动态脑电图能明显提高成人癫痫痫样波的阳性检出率,是诊断成人癫痫的重要检测手段。

24小时动态脑电图对儿童外侧裂癫癎的诊断价值及随访观察

目的:探讨24小时动态脑电图对儿童外侧裂癫癎的诊断价值及随访观察。方法:对105例临床诊断为儿童外侧裂癫癎的患儿进行常规脑电图和24小时动态脑电图检查,并对检查结果进行对比分析。结果:常规脑电图描记时出现异常放电21例(20%),在24小时动态脑电图描记时,全部病例均有异常放电,在随访观察中,儿童外侧裂癫癎临床发作停止2年脑电图异常放电会消失。结论:24小时动态脑电图对儿童外侧裂癫癎有重要诊断价值。

Blood Pressure Variability and Its Relationship with Cognitive Function in Elderly Patients with Essential Hypertension and Type 2 Diabetes

Objective: To investigate blood pressure variability of Elder hypertensives with type 2 diabetes and its relationship with cognition. Methods: A total of 143 elderly hypertensives were enrolled and divided into diabetic group (59 cases) and non-diabetic group (84 cases). The difference of general clinical characteristics, biochemical parameters, carotid ultrasound, a neuropsychological Scales and 24-hour ambulatory blood pressure (24hABPM) parameters between the two groups of subjects were compared. Then, the two groups (diabetic group and non-diabetic group) were further divided into (Mild cognitive dysfunction) subgroup (MMSE>26) and normal cognition subgroup (MMSE≤26), respectively. On the basis of MMSE scores, the difference of the parameters of ABPM between the two subgroups was analyzed. Results: Compared with the control group, 24hSBP, 24hPP, dSBP, dPP, nSBP, nPP, 24hSSD, dSSD, nSSD, 24hSCV, dSCV and nSCV were significantly higher in the diabetic group (p<0.05). However, cognition was lower in the diabetic group. No significant difference was found in the circadian pattern of blood pressure between the two groups. 24hSSD, dSSD, nSSD, 24hSCV, dSCV, nSCV were significantly higher in the MCI subgroup than normal cognition subgroup in both diabetic and non-diabetic groups(p<0.05), and they were negatively associated with scores of MMSE, the correlation coefficient were -0.235,-0.246,-0.341,-0.158,-0.222,-0.238 (0.001≤P<0.05). Conclusion: The study showed that in the elderly with hypertension, the mean systolic blood pressure and blood pressure variability were both higher in the diabetic group, and the cognition was lower instead. Whether or not with diabetes, blood pressure variability was always higher in the MCI subgroup. Blood pressure variability increased in patients with diabetes, and was associated with cognitive decline.
