阿尔茨海默病(AD)和相关疾病中的精神功能的破坏伴随着脑区域的选择性变性。这些区域由组织成心理功能系统的大规模细胞群组成,但痴呆症的临床症状、神经退行性变模式和功能系统之间的关系尚不清楚。在这里,我们提出了一个模型的痴呆症状和退行性脑解剖结构之间的关联使用F18-氟脱氧葡萄糖PET和降维技术在两个队列的AD患者。这反映了一个简单的基于信息处理的功能描述的宏观大脑解剖,我们链接到AD生理学,功能网络和心理能力。我们进一步将该模型应用于正常衰老和七种精神功能退行性疾病。我们提出了一个全球信息处理模型的心理功能,神经解剖学,认知神经科学和临床神经学。可能存在与痴呆综合征相关的脑功能解剖学的低维表示。在这里,作者提出了一个心理功能的计算模型,以分类阿尔茨海默氏症和相关痴呆症的这种解剖结构。
Disruption of mental functions in Alzheimer’s disease (AD) and related disorders is accompanied by selective degeneration of brain regions. These regions comprise large-scale ensembles of cells organized into systems for mental functioning, however the relationship between clinical symptoms of dementia, patterns of neurodegeneration, and functional systems is not clear. Here we present a model of the association between dementia symptoms and degenerative brain anatomy using F18-fluorodeoxyglucose PET and dimensionality reduction techniques in two cohorts of patients with AD. This reflected a simple information processing-based functional description of macroscale brain anatomy which we link to AD physiology, functional networks, and mental abilities. We further apply the model to normal aging and seven degenerative diseases of mental functions. We propose a global information processing model for mental functions that links neuroanatomy, cognitive neuroscience and clinical neurology. Low-dimensional representations of functional brain anatomy relevant for dementia syndromes may exist. Here the authors propose a computational model of mental functions to catalogue this anatomy in Alzheimer’s and related dementias.
