A cross-sectional and longitudinal study on the protective effect of bilingualism against dementia using brain atrophy and cognitive measures

open access: yesAlzheimer’s Research & Therapy, 2020
Background Evidence from previous studies suggests that bilingualism contributes to cognitive reserve because bilinguals manifest the first symptoms of Alzheimer’s disease (AD) up to 5 years later than monolinguals.

Masticatory function and cognitive function

open access: yesOkajimas Folia Anatomica Japonica, 2010
Recent studies have suggest that masticatory (chewing) function is useful for maintaining neurocognitive function in the elderly. For example, a reduced ability to masticate, such as that resulting from toothlessness or soft-diet feeding, causes learning and memory deficits in aged animals and pathologic changes in the hippocampus.

Fusion of quantitative susceptibility maps and T1-weighted images improve brain tissue contrast in primates

open access: yesNeuroImage, 2022
Recent progress in quantitative susceptibility mapping (QSM) has enabled the accurate delineation of submillimeter-scale subcortical brain structures in humans.

Sex and cognition: gender and cognitive functions [PDF]

open access: yesCurrent Opinion in Neurobiology, 2016
Gender stereotypes hold that males outperform females in mathematics and spatial tests, and females outperform males on verbal tests. According to meta-analyses, however, among both children and adults, females perform equally to males on mathematics assessments.

Hypertension and Cognitive Function

open access: yesClinical and Experimental Hypertension, 2008
Arterial hypertension, cerebrovascular disease, and dementia are related pathologies. This paper has reviewed comparatively the incidence of arterial hypertension and adult-onset dementia disorders. Hypertension is associated with cerebrovascular disease, which is in turn associated with dementia.

Integrated VASO and perfusion contrast: A new tool for laminar functional MRI

open access: yesNeuroImage, 2020
Earlier research in cats has shown that both cerebral blood volume (CBV) and cerebral blood flow (CBF) can be used to identify layer-dependent fMRI activation with spatial specificity superior to gradient-echo blood-oxygen-level-dependent (BOLD) contrast

Cognitive function and hypertension [PDF]

open access: yesJournal of Human Hypertension, 2008
The importance of lowering blood pressure (BP) in hypertensive subjects is well known but the relationship between hypertension and cognitive function is controversial. This article reviews the role of hypertension in the aetiology of cognitive impairment and the relationships between BP, cerebral perfusion and cognition. It also summarizes findings of

Does Motor Memory Reactivation through Practice and Post-Learning Sleep Modulate Consolidation?

open access: yesClocks & Sleep, 2023
Retrieving previously stored information makes memory traces labile again and can trigger restabilization in a strengthened or weakened form depending on the reactivation condition.

Butyrylcholinesterase and Cognitive Function

open access: yesInternational Psychogeriatrics, 2001
Butyrylcholinesterase (BuChE) is expressed in brain structures involved in cognition, but the effect of selective BuChE inhibitors on human cognitive function is unknown. We report a patient whose cognitive function deteriorated following a reduction and improved following reinstitution of ethopropazine, a selective BuChE inhibitor.

Cognitive function in COPD [PDF]

open access: yesEuropean Respiratory Journal, 2010
In order to characterise the overall clinical picture of chronic obstructive pulmonary disease (COPD) a better understanding of all relevant comorbidities is required. It is increasingly recognised that COPD is a multi-component disease, but little attention has been paid to its effects on cognitive function.Cognitive dysfunction is associated with ...
