- 神経学
- 免疫学
- 神経精神医学
背景:
- 自己免疫性脳炎症候群は、過去15年間で認識が高まっています。
- これらの状態は、自己免疫性神経学および新興分野である自己免疫性神経精神医学に影響を与えます。
- 多くの患者は、当初、精神状態の変化や行動変化を呈し、しばしば誤診され、抗精神病薬で治療されます。
研究 の 目的:
- 自己免疫性脳炎に関連する臨床症候群を記述すること。
- 細胞内および抗シナプス抗体に関連する自己免疫の原則を議論すること。
- 自己免疫性神経精神医学の概念とその意味を探求すること。
主な方法:
- 様々な自己抗体に関連する臨床症候群のレビュー。
- 抗体の病原性を含む自己免疫の原則の議論。
- 感染症、腫瘍、免疫チェックポイント阻害剤などの潜在的な誘因の分析。
- 治療戦略および予後因子の検討。
主要な成果:
- 中枢神経系抗原に対する自己抗体によって引き起こされる自己免疫性疾患は、免疫療法に劇的に反応します。
- 証拠は自己抗体の病原性と、感染症や腫瘍などの誘因を特定することを支持しています。
- 早期認識と診断は効果的な治療に不可欠です。
結論:
- 自己免疫性脳炎は、多様な臨床像を呈する重要な神経学的疾患です。
- 早期診断によって導かれる標的免疫療法は、転帰の改善につながります。
- 自己免疫性神経精神医学の分野は急速に進化しており、これらの状態を認識することの重要性を強調しています。

Autoimmune Disorders
1.4K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Psychosis and Antipsychotic Drugs: Overview
802
The term "psychosis" refers to a spectrum of mental disorders characterized by abnormal thoughts, perceptions, and behaviors. It can manifest as mood disorders, dementia, delirium with psychotic features, substance-induced psychosis with psychotic features, brief psychotic disorder, delusional disorder, schizoaffective disorder, and schizophrenia. Among all these disorders, schizophrenia is the most common psychotic disorder, affecting 1% of the worldwide population. Psychotic...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders
1.8K
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Dementia
511
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
1.6K
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...
