概括
结构性MRI和集群精确区分晚发性精神分裂症 (SCZ) 和阿尔茨海默氏症 (AD) 精神病. 被归类为SCZ的患者比被归类为AD的患者显示出更大的右骨体积.
科学领域:
- 神经成像是一种神经成像.
- 精神病学是一个精神病学.
- 老年学是一门学科.
背景情况:
- 晚发性精神病 (LOP) 是异质的,经常提出诊断挑战,区分精神分裂症 (SCZ) 与阿尔茨海默氏症 (AD).
- 准确的诊断对于LOP患者有效的治疗计划至关重要.
研究的目的:
- 采用数据驱动的结构磁共振成像 (MRI) 分析来区分LOP中的SCZ和AD.
- 探索皮层下体积差异在诊断LOP中的实用性.
主要方法:
- 从公开可用的SCZ和AD患者的MRI数据集中,利用K-意味着对皮下体积 (尾皮体,海马体,皮体,杏仁体) 的聚类.
- 应用训练集群模型,根据皮下体积对10名LOP患者进行分类.
- 计算的集群精度 (81%) 和AUC (0.79),用于区分SCZ和AD.
主要成果:
- 集群算法成功地在SCZ和AD患者之间进行了高准确度的区分.
- 在10名LOP患者中,有6人被归类为AD,有4人被归类为SCZ.
- 在SCZ集群中分类的LOP患者的右门体积明显大于AD集群中的患者 (p < 0.0025).
结论:
- 结构性MRI数据和集群算法在区分LOP亚型方面表现有前途.
- 布塔门体积可以作为潜在的神经成像标记,以帮助区分SCZ和LOP中的AD.
- 这些发现突出了LOP的异质性和可访问的神经成像方法的潜力,以改善诊断.

Alzheimer's Disease: Overview
447
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...

Biological Causes of Schizophrenia
46
Schizophrenia, a severe psychiatric disorder, arises from a complex interplay of biological factors, including genetic predisposition, structural brain abnormalities, neurotransmitter dysregulation, and developmental irregularities. These factors collectively contribute to the onset and progression of the disorder, which typically manifests in late adolescence or early adulthood.
Genetic Factors in Schizophrenia
The genetic basis of schizophrenia is strongly supported by family and twin...
