Brain and cognition change with age but the rates of change differ among individuals and across brain regions and cognitive domains, and the mechanisms of differential changes remain unclear. Multiple factors a
F. As people get older, changes occur in all parts of the body, including the brain.G. Trying to deal with these life changes leaves some people confused or forgetful.1.2.34.5. 答案 1.F【解题思路】根据上文“Forgetfulness can be a normalpart of aging."可知,健忘是衰老的正常表现。F项“...
There is still limited knowledge regarding the association of serum NfL (sNfL) with age and subclinical morphologic brain changes and their dynamics in the normal population. We measured sNfL by a single molecule array (Simoa) assay in 335 individuals participating in a population-based cohort ...
) , F 项: As people get older, changes occur in all parts of the body, including the brain.( 随着年龄的增长,身体的各个部位都会发生变化,包括大脑。 ) 承上启下。故选 F 。 【 2 】 根据后文 For example, medication side effects, vitamin B12 shortage, alcoholism, tumors( 肿瘤 ) or ...
Brain aging is accompanied by patterns of functional and structural change. Alzheimer’s disease (AD), a representative neurodegenerative disease, has been linked to accelerated brain aging. Here, we developed a deep learning-based brain age prediction m
This contribution on normal brain aging and dementias will not consider the not so frequent cerebral diseases leading to dementia during the senile or presenile period of life, such as Parkinson’s, Huntington’s, Pick’s and Creutzfeldt-Jakob’s...
changes. In addition, to reduce the number of explanatory variables to a minimum, we controlled for gender (mainly male subjects), comorbidity (excluding cases with other neuropathologies) and neuronal loss (excluding cases with severe loss; seeMethodssection “Brain tissue samples” for full ...

ASL also requires attention to partial volume effects (PVE), especially in older populations due to brain atrophy. Although PVE correction methods can mitigate the effect on CBF calculation, the smoothing effect intrinsic to these methods may reduce the sensitivity to detection of local CBF changes ...
