概括
狗的认知功能障碍 (CCD) 和肌细胞经常在老犬中同时发生. 虽然在统计学上没有联系,但肌细胞结核在患有认知衰退的老年犬中需要考虑CCD.
科学领域:
- 兽医神经学 兽医神经学
- 狗医疗 狗医疗 狗医疗
- 神经退行性疾病 神经退行性疾病
背景情况:
- 狗的认知功能障碍 (CCD) 在狗中越来越多地被诊断出来.
- 一组患有CCD的狗也表现出肌,其特征是无意的肌肉抽.
- 慢性痴呆与阿尔茨海默病有相似之处,肌细胞与人类的神经退行性疾病有关.
研究的目的:
- 为了调查狗狗中肌肉瘤的发生,这些狗狗表现出CCD的临床症状.
- 在这个人群中描述肌细胞瘤的特征和触发因素.
主要方法:
- 一项在线调查分发给老年犬 (7岁以上) 的所有者.
- 该调查包括信号,用于CCD评估的犬类痴呆症量表 (CADES) 和关于肌肉克隆的问题.
- CCD被定义为一个CADES得分大于8.
主要成果:
- 在401名参与者中,164只狗符合纳入标准.
- 89%的主人报告了CCD的症状,89.0%的这些狗也表现出肌.
- 最常见的是发生自发性 (72.6%),紧随其后的是压力诱导 (15.2%) 和光诱导 (11.6%) 的触发. 没有发现CCD和肌细胞结核之间有显著的统计学关联 (p=0.45).
结论:
- 经常在患有CCD的狗中报告肌.
- 虽然在统计学上没有相关性,但在患有肌细胞瘤的老年犬的差异诊断中应考虑CCD,特别是如果认知能力下降也存在.

Pharmacodynamics in Geriatric Patients: Effects of Age
309
Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

Alzheimer's Disease: Overview
1.9K
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...

Seizures: Classification
2.0K
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:

Parkinson's Disease: Overview
2.3K
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is...

Drug Dosing: Geriatric Patients
344
Elderly individuals encompass a diverse population with varying degrees of age-related physiological changes. Defining the elderly presents challenges, as the geriatric population is often arbitrarily categorized as individuals older than 65. However, many individuals in this group lead active and healthy lives, with an increasing number surpassing 85 years and falling into the older elderly category. Physiological changes associated with aging impact performance capacity and homeostatic...

Alzheimer's Disease: Treatment
1.1K
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
