  1. Repeated Transcranial Magnetic Stimulation for Improving Cognition in Alzheimer Disease: Protocol for an Interim Analysis of a Randomized Controlled Trial

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. JMIR research protocols 2021-08-09 Treatments

    Overall, the study with the same protocol is going as expected with no serious AE or any major protocol deviation.

    Why it matters

    This is a protocol paper describing how an ongoing randomized trial of repetitive transcranial magnetic stimulation will be analyzed partway through, so it does not yet report whether the treatment works. Enrollment has been slowed by the COVID-19 pandemic, and no serious adverse events or major protocol deviations have occurred so far.

  2. Role of Neuron and Glia in Alzheimer's Disease and Associated Vascular Dysfunction

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Frontiers in aging neuroscience 2021-06-15 TREM2 and immune genetics

    Amyloidogenicity and vascular dysfunction are the key players in the pathogenesis of Alzheimer's disease (AD), involving dysregulated cellular interactions.

    Why it matters

    This review describes how the balance between neurons, astrocytes, microglia, oligodendrocytes and vascular cells sustains normal neuronal circuits, and how glial dyshomeostasis promotes the Alzheimer's-associated neurodegenerative cascade. It also notes that cerebrovascular diseases overlap neuropathologically with Alzheimer's disease, suggesting that vascular dysfunction is a key player in its pathogenesis.

  3. COVID-19 and Alzheimer's disease: how one crisis worsens the other

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Translational neurodegeneration 2021-04-30 Clinical safety

    Alzheimer's disease (AD) has emerged as a key comorbidity of coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2).

  4. Reactive astrocytes: The nexus of pathological and clinical hallmarks of Alzheimer's disease

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Ageing research reviews 2021-03-31 Inflammation and the immune system

    Astrocyte reactivity is a hallmark of neuroinflammation that arises with Alzheimer's disease (AD) and nearly every other neurodegenerative condition.

  5. Crosstalk between Gut and Brain in Alzheimer's Disease: The Role of Gut Microbiota Modulation Strategies

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Nutrients 2021-02-21 Inflammation and the immune system

    The gut microbiota (GM) represents a diverse and dynamic population of microorganisms and about 100 trillion symbiotic microbial cells that dwell in the gastrointestinal tract.

  6. Cerebrospinal Fluid Biomarkers of Alzheimer's Disease: Current Evidence and Future Perspectives

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Brain sciences 2021-02-10 Disease mechanisms

    Alzheimer's disease is a progressive, clinically heterogeneous, and particularly complex neurodegenerative disease characterized by a decline in cognition.

  7. The Immunopathogenesis of Alzheimer's Disease Is Related to the Composition of Gut Microbiota

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Nutrients 2021-01-25 Prevention trials

    The microbiota-gut-brain axis plays an important role in the development of neurodegenerative diseases.

  8. It accounts for a quarter of the elderly population and is associated with cognitive decline.

    Why it matters

    This imaging study compared brain functional impairment patterns in people with suspected non-Alzheimer disease pathophysiology (negative amyloid but abnormal tau) versus Alzheimer's disease. It is a brain-imaging comparison, so it does not show a treatment, cure or prevention.

  9. Functional connectivity of white matter as a biomarker of cognitive decline in Alzheimer's disease

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. PloS one 2020-10-16 Digital health tools

    The white matter FC decreased in late MCI and AD dementia patients compared to CN participants, and this decrease was correlated with cognitive measures.

    Why it matters

    This study of 383 people found that functional connectivity in white matter decreased with cognitive decline in Alzheimer's disease, with specific regional deficits appearing in late mild cognitive impairment and Alzheimer's dementia, and these changes correlated with thinking test scores. It is about using brain imaging as a marker of decline, not about treating, curing or preventing the disease.

  10. Causal Associations Between Modifiable Risk Factors and the Alzheimer's Phenome

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Annals of neurology 2020-10-15 Hippocampus size on brain scans

    Our comprehensive examination of the genetic evidence for the causal relationships between previously reported risk factors in AD using PRS and MR supports a causal role for education, blood pressure, cholesterol levels, smoking, and diabetes with the AD phenome.

  11. Interrelations of Alzheimer´s disease candidate biomarkers neurogranin, fatty acid-binding protein 3 and ferritin to neurodegeneration and neuroinflammation

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Journal of neurochemistry 2020-09-18 Tau biomarkers

    There is growing evidence that promising biomarkers of inflammation in Alzheimer´s disease (AD) and other neurodegenerative diseases correlate strongest to levels of tau or neurofilament, indicating an inflammatory response to neuronal damage or death.

    Why it matters

    This study measured ferritin, FABP-3 and neurogranin in CSF and looked at how they relate to established Alzheimer's and inflammation markers. It investigates possible biomarker links but does not test any treatment or show a way to prevent the disease.

  12. Prognostic value of ATN Alzheimer biomarkers: 60-month follow-up results from the Argentine Alzheimer's Disease Neuroimaging Initiative

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Alzheimer's & dementia (Amsterdam, Netherlands) 2020-05-22 Tau biomarkers

    Twenty-three patients with mild cognitive impairment (MCI), 12 dementia of Alzheimer's type (DAT), and 14 normal controls were studied following the ADNI2 protocol.

    Why it matters

    This 60-month follow-up classified Argentine participants by amyloid, tau and neurodegeneration biomarkers and described how they progressed. It shows these biomarkers may help predict outcomes, but it does not test any treatment or cure.

  13. Amyloid PET in Dementia Syndromes: A Chinese Multicenter Study

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Journal of nuclear medicine : official publication, Society of Nuclear Medicine 2020-05-08 Biomarkers

    Of the 1,193 CI patients, 860 (72.1%) were amyloid-positive.

    Why it matters

    In 1,193 people with cognitive impairment, amyloid PET was positive in 86.8% of those with Alzheimer's disease and in only 5.6% of those with frontotemporal dementia, and the APOE ε4 allele was more frequent in amyloid-positive cases. This supports amyloid imaging for differential diagnosis, not for treating, curing or preventing Alzheimer's disease.

  14. Circulating Vitamin D Levels and Alzheimer's Disease: A Mendelian Randomization Study in the IGAP and UK Biobank

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Journal of Alzheimer's disease : JAD 2020-01-01 Long-term cohort studies

    Observational studies strongly supported the association of low levels of circulating 25-hydroxyvitamin D (25OHD) and cognitive impairment or dementia in aging populations.

    Why it matters

    This study used a genetic method called Mendelian randomization to test whether vitamin D levels directly affect the risk of Alzheimer's disease. The approach helps distinguish causation from mere association, which is important because randomized trials have not shown clear cognitive benefits from vitamin D supplementation.

  15. Benchmarking machine learning models for late-onset alzheimer's disease prediction from genomic data

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. BMC bioinformatics 2019-12-16 Digital health tools

    Machine learning models are promising alternatives for estimating the genetic risk of LOAD.

    Why it matters

    Machine learning models using genetic data predicted late-onset Alzheimer's disease with about 72% area under the ROC curve, which is not high enough to be a stand-alone diagnostic test. This work may help identify new genetic markers linked to the disease, but it does not provide a treatment, cure or prevention.

  16. Down syndrome, Alzheimer disease, and cerebral amyloid angiopathy: The complex triangle of brain amyloidosis

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Developmental neurobiology 2019-07-01 Down syndrome and Alzheimer's

    Down syndrome (DS) is the main genetic cause of intellectual disability worldwide.

    Why it matters

    This review describes that overexpression of amyloid precursor protein in Down syndrome leads to beta-amyloid deposition resulting in Alzheimer's disease and often cerebral amyloid angiopathy, with people with Down syndrome developing Alzheimer's neuropathology at age 40. It highlights the need for large biomarker-characterized cohorts and does not report a treatment or cure.

  17. Understanding the Role of Systemic Inflammation in Alzheimer's Disease

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. ACS chemical neuroscience 2019-06-26 Inflammation and the immune system

    Human and animal studies suggest that inflammation occurring outside the central nervous system (systemic inflammation) may play a key role in promoting neurodegeneration, Alzheimer's disease pathology, and cognitive decline in older adults.

    Why it matters

    This review discusses how inflammation outside the brain may promote neurodegeneration and Alzheimer's pathology and cognitive decline in older adults. It does not report a specific treatment, cure, or prevention for Alzheimer's disease.

  18. Potential Diagnostic Value of Red Blood Cells α-Synuclein Heteroaggregates in Alzheimer's Disease

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Molecular neurobiology 2019-03-02 Biomarkers

    A plethora of complex misfolded protein combinations have been found in Alzheimer disease (AD) brains besides the classical pathological hallmarks.

    Why it matters

    Red blood cells from people with early Alzheimer disease had lower levels of alpha-synuclein and its complexes with amyloid-beta and tau than healthy controls. This suggests a possible peripheral marker, but the study was small and did not show whether measuring it helps diagnosis or treatment.

  19. Genome-wide analysis of genetic predisposition to Alzheimer's disease and related sex disparities

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Alzheimer's research & therapy 2019-01-12 Disparities

    Alzheimer's disease (AD) is the most common cause of dementia in the elderly and the sixth leading cause of death in the United States.

    Why it matters

    This genetic analysis corroborated previously detected Alzheimer's disease loci and found 35 single-nucleotide polymorphisms outside the chromosome 19q13 region at a suggestive significance level, including possible sex-specific contributors. It is a genetic association analysis and does not test any treatment, cure, or prevention.

  20. CD33 in Alzheimer's Disease - Biology, Pathogenesis, and Therapeutics: A Mini-Review

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Gerontology 2018-12-12 TREM2 and immune genetics

    Alzheimer's disease (AD) affects nearly 50 million people worldwide, and currently no disease-modifying treatment is available.

    Why it matters

    This review discusses CD33 and immune-inflammatory pathways as possible targets in Alzheimer's disease and notes that no disease-modifying treatment is currently available. It is a summary of biology and target ideas, not evidence that any treatment, cure, or prevention works.

  21. Diabetes and Alzheimer's Disease: Mechanisms and Nutritional Aspects

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Clinical nutrition research 2018-10-23 Prevention and risk

    Blood glucose homeostasis is well maintained by coordinated control of various hormones including insulin and glucagon as well as cytokines under normal conditions.

    Why it matters

    This review reports that hyperglycemia is closely related to cognitive impairment and dementia, suggesting a possible cause-effect relationship, and speculates that glucotoxicity may damage brain cells and increase amyloid beta accumulation. It does not test any treatment or prevention for Alzheimer's disease.

  22. SPECT and PET imaging in Alzheimer's disease

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Annals of nuclear medicine 2018-08-20 Mild cognitive impairment

    Alzheimer's disease (AD) is a progressive neurodegenerative disorder and the most common cause of dementia.

    Why it matters

    This review describes how SPECT and PET imaging can detect beta-amyloid deposits, tau protein accumulation, and other pathological processes in Alzheimer's disease. The findings are about using imaging as biomarkers for early diagnosis and prediction of progression, not about treating, curing, or preventing the disease.

  23. Genetic variants associated with Alzheimer's disease confer different cerebral cortex cell-type population structure

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Genome medicine 2018-06-08 TREM2 and immune genetics

    Alzheimer's disease (AD) is characterized by neuronal loss and astrocytosis in the cerebral cortex.

    Why it matters

    Using cell-type deconvolution across three transcriptomic studies, this work found that neuronal and astrocyte proportions differ between healthy and diseased brains and among Alzheimer's disease-associated genetic variants. These are descriptive cellular findings and do not demonstrate a treatment, cure or prevention.

  24. Generation of Structural MR Images from Amyloid PET: Application to MR-Less Quantification

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Journal of nuclear medicine : official publication, Society of Nuclear Medicine 2017-12-07 Biomarkers

    Generated MR images from florbetapir PET showed signal patterns that were visually similar to the real MR. The structural similarity index between real and generated MR was 0.91 ± 0.04.

    Why it matters

    This study used deep generative networks to create structural MR images from amyloid PET scans, allowing accurate amyloid quantification without a real MR. It is a technical imaging method and does not test any treatment, cure or prevention.

  25. Decreased Complexity in Alzheimer's Disease: Resting-State fMRI Evidence of Brain Entropy Mapping

    ✓ Peer-reviewed alzhub usefulness score 43 out of 100. Frontiers in aging neuroscience 2017-11-20 Cognitive tests and assessment

    Alzheimer's disease (AD) is a frequently observed, irreversible brain function disorder among elderly individuals.

    Why it matters

    This study used resting-state fMRI and permutation entropy to examine brain signal complexity in people with mild cognitive impairment and Alzheimer's disease compared with normal controls. It is an imaging study of brain function, not a treatment, cure or prevention study.
