Risk Factors for Delirium and Cognitive Decline Following Coronary Artery Bypass Grafting Surgery: A Systematic Review and Meta‐Analysis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020
Background Coronary artery bypass grafting (CABG) is known to improve heart function and quality of life, while rates of surgery‐related mortality are low. However, delirium and cognitive decline are common complications.

Adiponectin Mediates the Protection of H2S Against Chronic Restraint Stress-Induced Cognitive Impairment via Attenuating Hippocampal Damage

Frontiers in Behavioral Neuroscience, 2021
Emerging evidence shows that chronic restraint stress (CRS) can induce cognitive dysfunction, which involves in hippocampal damage. Our recent research reveals that hydrogen sulfide (H2S), a novel gasotransmitter, protects against CRS-induced cognitive ...

Mild cognitive impairment

Srpski arhiv za celokupno lekarstvo, 2009
Mild cognitive impairment (MCI) is a syndrome that spans the area between normal ageing and dementia. It is classified into amnestic and non-amnestic types, both with two subtypes: single domain and multiple domains. Prevalence of MCI depends on criteria and population and can vary from 0.1 to 42% persons of older age.

Enriched environment attenuates hippocampal theta and gamma rhythms dysfunction in chronic cerebral hypoperfusion via improving imbalanced neural afferent levels

Frontiers in Cellular Neuroscience, 2023
Chronic cerebral hypoperfusion (CCH) is increasingly recognized as a common cognitive impairment-causing mechanism. However, no clinically effective drugs to treat cognitive impairment due to CCH have been identified.

Mild cognitive impairment [PDF]

CNS Spectrums, 2008
Publisher Summary This chapter describes mild cognitive impairment (MCI) as a degree of cognitive impairment, which is abnormal for a given individual, and yet is insufficient to warrant a diagnosis of dementia. The chapter explains that the diagnosis of MCI requires only a subjective complaint of cognitive deterioration and some objective evidence of

Acid-Sensing Ion Channel 1/Calpain1 Activation Impedes Macrophage ATP-Binding Cassette Protein A1-Mediated Cholesterol Efflux Induced by Extracellular Acidification

Frontiers in Physiology, 2022
BackgroundExtracellular acidification is a common feature of atherosclerotic lesions, and such an acidic microenvironment impedes ATP-binding cassette transporter A1 (ABCA1)-mediated cholesterol efflux and promotes atherogenesis.
