Shared Reference Notes

  • [1.1] [#Keto diet
    - Carbohydrate-restricted (ketogenic) diet potentiates CI induced by intermittent hypoxia in mice and alters the gut microbiota. - Depleting the microbiome reduces CI, whereas transplantation of the risk-associated microbiome or monocolonization with #Bilophila wadsworthia confers CI in mice fed a standard diet. - B. wadsworthia and the risk-associated microbiome disrupt hippocampal synaptic plasticity, neurogenesis, and gene expression. - The CI is associated with microbiome-dependent increases in intestinal interferon-gamma (IFNg)-producing Th1 cells. - Inhibiting Th1 cell development abrogates the adverse effects of both B. wadsworthia and environmental risk factors on CI.
  • [1.2
    - #Barnesiella was positively associated with the first principal component, DSST, and category fluency; - #Lachnospiraceae FCS020 group was positively associated with DSST. - #Sutterella was negatively associated with MoCA
  • [1.3] [#Antibiotic Therapy
    - Long-term antibiotic use in midlife is associated with small decreases in cognition assessed seven years later.
  • [1.4] [#Alzheimer’s disease, #Mild Cognitive Impairment] [#Mediterranean Ketogen Diet
    - Participants with MCI on the MMKD had lower levels of #GABA-producing microbes #Alistipes sp. CAG:514 and #GABA, and higher levels of #GABA-regulating microbes #Akkermansia muciniphila.
  • [#American Heart Association Diet] - the low-fat AHAD modulates key #Neurotransmitters, such as promoting #GABA production, in individuals with cognitive impairment. This dysregulation may be related to increases in #GABA-producing microbes, such as #Alistipes sp. CAG:514.
  • [1.5
    - #Butyrate administration to animals has shown protective effects against vascular #Dementia, cognitive impairment, and against metabolic risk factors for cognitive decline and #Dementia
  • [#Mild Cognitive Impairment] [#Bacteriophage] - higher abundance of #Lactobacillus phages (family #Siphoviridae of the order #Caudovirales positively associated with better cognitive function; and transplantation of these phages from humans to mice and Drosophila showed increased memory scores and upregulation of memory-involved brain genes.
  • [1.6] [#Mild Cognitive Impairment] [#Olive
    - participants who consumed a #Mediterranean diet supplemented with either EVOO or #Nuts had improved cognitive function compared with those that consumed a low-fat diet.
  • [#Olive] - increase in complexin 1, a presynaptic neuronal protein, and a notable decrease in tau oligomers in mice fed EVOO, resulting in enhanced short-term plasticity and memory.
  • [1.7] [#Alzheimer’s disease] [#Amyloid-beta
    - Aβ was associated with increased plasma phosphorylated tau and cognitive impairment only in those who tested positive for astrocyte reactivity (Ast+).
  • [1.8] [#Alzheimer’s disease] [#Lipopolysaccharide
    - in patients with cognitive impairment due to AD, (i) sPECAM-1, sP-, sE-Selectins, and IL6 were associated with #Amyloid and #Tau pathology; (ii) sP-Selectin, sNCAM, and the decrease of IL10 with neurodegeneration; and (iii) LPS and IL1β with cognitive impairment.
  • [1.9] [#Short Chain Fatty Acid
    - The pathway most associated with healthy individuals (l-#Glutamate degradation V) produces the SCFA #Acetate, which not only has been observed to inhibit Aβ aggregation in vitro and protect against cognitive impairment in mice but also has been associated with an elevated Aβ SUVR in a human cohort
  • [#Faecalibacterium prausnitzii] - specific strains of F. prausnitzii from healthy participants reduced cognitive impairment in a murine model of brain amyloidosis.
  • - #Constipation may not be a necessary condition for steeper cognitive decline. Rather, a condition without #Constipation may support a relatively slow decline in cognitive impairment.
  • [1.11] [#Glutamate, #Glutamine
    - Disruption within the glutamatergic pathway can lead to cognitive deficits, #Schizophrenia and frontotemporal #Dementia
  • [1.12] [#Lactobacillus plantarum
    - Intake of Lactiplantibacillus plantarum LPHEAL9 significantly improved cognitive functions compared to the placebo, potentially by ameliorating aspects of mood and #Sleep.
  • [1.13] [#Alzheimer’s disease
    - administrating feces of AD transgenic mice to wild-type mice resulted in AD-associated gut microbiota dysbiosis, #Tau phosphorylation, and cognitive impairment in the wild-type mice. - The oral and gut microbiota of AD patient partners resembled that of AD patients but differed from healthy controls, indicating the transmission of microbiota. - #Butyric acid-mediated acetylation of GSK3β at lysine 15 regulated its phosphorylation at serine 9, consequently impacting #Tau phosphorylation.
  • [1.14
    - #Arabinoxylan and #Arabinose, can enhance general cognition and attenuate the accumulation process of #Dementia-related glial fibrillary acidic protein in mice
  • [1.15] [#Depression, #Hearing loss
    - significant negative correlation between urinary #Glyphosate levels and cognitive function. - severe depressive symptoms were significantly higher than having no symptoms in individuals with higher #Glyphosate levels. - individuals reporting serious hearing difficulty in individuals with higher #Glyphosate levels.
  • [1.16] [#Alzheimer’s disease
    - co-housing wild-type mice with AD transgenic mice or giving them AD transgenic mice feces caused AD-associated gut microbiota dysbiosis, #Tau phosphorylation, and cognitive impairment. - Gavage with #Lactobacillus and #Bifidobacterium restored these changes.
  • [1.17] [#Malondialdehyde] [#Citrus and pomegranate complex
    - After four weeks of supplementation with CPC, handgrip strength significantly improved, as compared to placebo, which deteriorated. - self-evaluated psychological function showed a trend for improvement after CPC supplementation > significantly higher score for the CPC group in the thinking, memory, learning, and concentration facet, as compared to the placebo group. - a significant decrease in MDA was observed after CPC supplementation.
  • [1.18] [#Dairy
    - cheese intake was found to be a factor that was inversely associated with lower cognitive function.
  • [#Whole grains] - grain products increased their risk of cognitive decline by 40%, whereas an increased intake of #Dairy products reduced the risk of cognitive decline by 20%
  • [1.19] [#Lipopolysaccharide
    - TG-treated SAMP8 mice exhibited significant improvement in the parameters of escape latency, distance moved, and annulus crossing index. - #Trigonelline treatment significantly reduces TNFα and IL6 protein levels in SAMP8 mice hippocampus. - it also suppressed LPS-induced TNFα mRNA expression in SH-SY5Y cells. - TG may exert its biological effects through negatively modulating Traf6-mediated NF-κB activation.
  • - decrease in #Prevotella histicola and #Prevotella oulorum > in the oral cavity of patients with #Rheumatoid Arthritis, and cognitive decline
  • [1.21] [#Nuts
    - higher nut intake was associated with better cognitive function.
  • [1.22] [#Alzheimer’s disease
    - repeated short exposures to #Menthol odor enhanced the immune response against ovalbumin immunization. - #Menthol inhalation also improved the cognitive capacity of immunocompetent mice but not in immunodeficient NSG mice, which exhibited very poor fear-conditioning. - Exposure to #Menthol for 6 months (1 week per month) prevented the cognitive impairment observed in the APP/PS1 mouse model of Alzheimer. - this improvement was also observed by the depletion or inhibition of T regulatory cells.
  • [1.23] [#Alzheimer’s disease] [#Porphyromonas gingivalis
    - patients with AD exhibited higher blood levels of anti-P. gingivalis IgG > is associated with specific cognitive impairment
  • [1.24] [#Constipation
    - Compared to those with BM once daily, participants with BM frequency every 3+ days had significantly worse objective cognitive function, equivalent to 3.0 years of chronological cognitive #Aging.
  • [1.25
    - genus #Eisenbergiella increases with severity of cognitive impairment and that genus #Desulfovibrio was negatively correlated with MMSE scores.
  • [1.26] [#Prevotella intermedia
    - serum antibody levels specific for P. intermedia have been reported to be associated with cognitive deficits
