概括

针对异常性正常压力脑症 (iNPH) 的转移手术改善了口头记忆和处理速度,抑郁症状减少. 然而,在手术后三个月,认知功能仍然低于健康对照组.

科学领域:

神经外科神经外科
神经学神经学
认知神经科学认知神经科学

背景情况:

异常性正常压力脑症 (iNPH) 是一种神经疾病,其特征是走路障碍,尿失禁和认知障碍.
旁路手术是iNPH的主要治疗方法,旨在通过排出多余的脑脊液来缓解症状.

研究的目的:

评估iNPH患者在分流手术后三个月的认知和情绪变化.
为了将iNPH患者的术后认知表现与年龄,性别和教育匹配的健康对照进行比较.

主要方法:

33名iNPH患者在手术前和手术后三个月完成了神经心理测试.
71名健康对照被评估一次进行比较.
认知测试被分为六个领域:语言记忆,非语言记忆,执行功能,语言,视觉空间能力和精神运动节奏.

主要成果:

位导致口头记忆和精神运动速度的显著改善,在执行功能中有选择性的收益.
在非语言记忆,语言或视觉空间能力方面没有观察到显著的术后变化.
抑郁症状显著下降,但iNPH患者在三个月后在所有认知领域的表现比对照表现更差 (p < 0.001).

结论:

旁路手术在iNPH患者中提供了可衡量的,尽管是特定领域的认知益处,特别是在口头学习和处理速度方面,以及情绪提升.
尽管情况有所改善,但三个月后的认知表现仍然低于健康个体,仅表明部分恢复.
需要对更大的队列和更长的随访进行进一步的研究,以确定长期的耐用性和认知益处的广度,并确定治疗反应的预测因素.

Increased Intracranial Pressure l: Introduction

Increased Intracranial Pressure l: Introduction

Intracranial hypertension is a sustained elevation of intracranial pressure (ICP) above 22 mm Hg. In supine adults, normal ICP is ~7–15 mm Hg.The rigid, nonexpandable cranium contains three components—brain tissue, blood, and cerebrospinal fluid (CSF)—that total ~1,700 mL in a typical adult: 1,400 mL brain (~80%), 150 mL blood (~10%), and 150 mL CSF (~10%). According to the Monro–Kellie doctrine, total intracranial volume is effectively fixed. When one component expands, CSF and venous blood...

Increased Intracranial Pressure ll: Pathophysiology

Increased Intracranial Pressure ll: Pathophysiology

Increased intracranial pressure (ICP) refers to a potentially life-threatening rise in pressure inside the skull. This usually happens when there is a major change in the volume of brain tissue, blood, or cerebrospinal fluid (CSF) — the three components inside the skull. According to the Monro-Kellie doctrine, if the volume of one component increases, the volumes of the other components must decrease to maintain normal pressure. If this does not happen, ICP rises.The process often begins with...
