概括
神经精神病症状 (NPS) 在轻度神经认知障碍 (Mild NCD) 和缓解性主要抑郁障碍 (rMDD) 中很常见. 结合的轻度NCD-rMDD组显示了最高的NPS频率,在各组之间有明显的症状模式.
科学领域:
- 神经科学是一个神经科学.
- 精神病学是一个精神病学.
- 老年学是一门学科.
背景情况:
- 神经心理症状 (NPS) 在神经认知障碍中很普遍.
- 了解像轻度神经认知障碍 (Mild NCD) 和缓解性主要抑郁障碍 (rMDD) 这样的痴呆风险状态中的NPS差异至关重要.
- 这项研究调查了NPS在轻度NCD,rMDD和组合轻度NCD-rMDD组中的NPS.
研究的目的:
- 为了比较NPS的频率和因子结构.
- 在轻度NCD,rMDD和轻度NCD-rMDD队列中区分NPS呈现.
- 为未来关于痴呆风险和进展的研究提供信息.
主要方法:
- 来自多中心试验的基线数据的分析 (NCT0238667).
- 使用神经精神病学库存问卷评估NPS的评估.
- 在三组参与者中对NPS频率和因子结构进行比较分析.
主要成果:
- 与轻度NCD (63.5%) 和rMDD (55.7%) 相比,轻度NCD-rMDD组 (75.9%) 的NPS总体频率最高.
- 抑郁症/失恋症是所有组中最常见的NPS.
- 因子分析揭示了四个常见的NPS结构,但在不同组中症状组成不同.
结论:
- 在痴呆症高风险状态中,NPS很常见,在组合轻度NCD-rMDD组中频率较高.
- 在轻度NCD,rMDD和轻度NCD-rMDD之间存在NPS呈现的显著差异.
- 需要进一步的研究来探索这些NPS差异对认知,功能和生物标志物的临床影响.

Dementia
182
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.

Alzheimer's Disease: Overview
684
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...

Negative and Cognitive Symptoms of Schizophrenia
129
Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Alzheimer's Disease: Treatment
265
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...

Positive Symptoms of Schizophrenia: Hallucinations and Delusions
223
Schizophrenia is a complex mental health disorder that can manifest with various positive symptoms, including thought, movement, and behavior disorders. These symptoms significantly disrupt cognitive and motor functions, leading to profound effects on an individual's ability to engage with the world.
Thought Disorders
Disorganized and unusual thought processes mark thought disorders in schizophrenia. One key feature is disorganized speech, where an individual's conversation includes...

Disorders of the Nervous Tissue

Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.
