概括
患有勒维体 (DLB) 痴呆症的患者有更多的发作. 长期耳朵脑电图 (EEG) 在大多数DLB患者中揭示了间接性发性放电 (IED),比健康对照群更频繁.
科学领域:
- 神经学 神经学
- 神经科学是一个神经科学.
- 医学诊断 医学诊断 医学诊断
背景情况:
- 患有莱维体痴呆症 (DLB) 患者的发作风险高于健康人群或其他神经退行性疾病患者.
- 在DLB中的病态α-synuclein沉积可以增加网络刺激性,可能导致发作.
- 间接性性排泄 (IED) 是脑电图 (EEG) 发作活动的指标,但它们在DLB中的发生仍未研究.
研究的目的:
- 为了确定与健康对照组 (HC) 相比,在患有莱维体 (DLB) 痴呆症患者中,间接性发性排泄 (IED) 是否更频繁,使用耳朵电脑电图 (耳朵EEG).
主要方法:
- 一项纵向观察性研究包括10名DLB患者和15名HC患者.
- 在6个月内,DLB患者接受了多达3次2天的耳朵EEG记录.
- 分析了IED发生率和峰值频率.
主要成果:
- 在80%的DLB患者中检测到IED,而在基线时HC的46.7%.
- 与HC相比,DLB患者的尖峰频率 (每24小时的尖峰/尖波) 显著更高 (风险比率=2.52,P=0.001).
- 大多数IED事件记录在夜间.
结论:
- 长期的耳部EEG监测可以有效地检测大多数DLB患者的IED.
- 与HC相比,DLB患者的IED频率较高.
- 这表明发性排泄可能是DLB神经退行以及潜在的其他神经退行性疾病的后果.

Dementia

Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Epilepsy is a chronic neurological disease marked by recurrent, unpredictable seizures. These seizures are caused by abnormal electrical discharges in the brain, leading to behavior, sensation, or consciousness alterations. They can also cause transient impairment of awareness, interfering with daily activities.
Various factors can trigger epilepsy, including genetic factors, brain damage, metabolic causes, and unknown etiology. Diagnosis of epilepsy involves electroencephalography (EEG), which...

Seizures: Classification
426
Epilepsy is primarily characterized by unpredictable seizures, either provoked by an identifiable factor, such as injury or illness, or unprovoked, occurring spontaneously without apparent cause.
Seizures are typically classified into two main categories: focal and generalized seizures.
Focal Seizures
Focal seizures originate from specific regions of the brain. These seizures are further sub-classified into two types:

Alzheimer's Disease: Overview
525
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...
