  1. TDP-43 proteinopathies: a new wave of neurodegenerative diseases

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Journal of neurology, neurosurgery, and psychiatry 2020-11-11 Lewy body dementia

    Inclusions of pathogenic deposits containing TAR DNA-binding protein 43 (TDP-43) are evident in the brain and spinal cord of patients that present across a spectrum of neurodegenerative diseases.

    Why it matters

    This review describes the role of TDP-43 in ALS and frontotemporal lobar degeneration and notes that understanding its disease mechanisms is critical for developing effective therapies. It does not test any treatment or prevention for Alzheimer's disease, so it has no direct implications for treating, curing, or preventing the disease.

  2. Proteomic Profiling of Extracellular Vesicles Derived from Cerebrospinal Fluid of Alzheimer's Disease Patients: A Pilot Study

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Cells 2020-08-25 Mild cognitive impairment

    Pathological hallmarks of Alzheimer's disease (AD) are deposits of amyloid beta (Aβ) and hyper-phosphorylated tau aggregates in brain plaques.

    Why it matters

    In this small pilot study of cerebrospinal fluid from 13 Alzheimer's, 10 mild cognitive impairment and 10 control samples, three proteins were identified that may help monitor progression from mild cognitive impairment to Alzheimer's. It is early biomarker work and does not show any treatment, cure or prevention.

  3. Progression of grey and white matter brain damage in Parkinson's disease: a critical review of structural MRI literature

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Journal of neurology 2020-05-06 Mild cognitive impairment

    The current review summarizes the current knowledge on longitudinal cortical and subcortical grey and white matter MRI findings assessed using T1-weighted and one-tensor diffusion-weighted MRI in Parkinson's disease (PD) patients.

    Why it matters

    This review of MRI studies in Parkinson's disease describes progressive brain atrophy and notes that only a few studies used MRI to predict cognitive impairment or dementia conversion. It concerns Parkinson's disease and reports no treatment or prevention results.

  4. Enhancing protective microglial activities with a dual function TREM2 antibody to the stalk region

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. EMBO molecular medicine 2020-03-10 TREM2 and immune genetics

    Triggering receptor expressed on myeloid cells 2 (TREM2) is essential for the transition of homeostatic microglia to a disease-associated microglial state.

    Why it matters

    Researchers screened antibodies against TREM2, a receptor on the brain's immune cells, looking for one that stops enzymes from cutting it off the cell surface. One antibody, 4D9, both kept TREM2 on the cell surface and "concomitantly" switched on its internal signalling, helped macrophages survive, and in a living-animal test bound "nearly all soluble TREM2" in cerebrospinal fluid. This shows the antibody reaches its target in the lab and in vivo. It does not show any effect on Alzheimer's pathology or symptoms.

  5. Perivascular spaces in the brain: anatomy, physiology and pathology

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Nature reviews. Neurology 2020-02-24 Brain scans and imaging

    Perivascular spaces include a variety of passageways around arterioles, capillaries and venules in the brain, along which a range of substances can move.

    Why it matters

    This review describes perivascular spaces and their role in clearing fluid and waste from the brain, and notes their involvement in small vessel disease and Alzheimer's disease. It is a review of anatomy, physiology and pathology and reports no treatment that cures or prevents Alzheimer's disease.

  6. Brain iron deposition is linked with cognitive severity in Parkinson's disease

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Journal of neurology, neurosurgery, and psychiatry 2020-02-20 Cognitive tests and assessment

    Dementia is common in Parkinson's disease (PD) but measures that track cognitive change in PD are lacking.

    Why it matters

    This study used quantitative susceptibility mapping to detect brain iron changes related to cognitive change in Parkinson's disease. It concerns an imaging marker in Parkinson's disease and does not test treating, curing or preventing Alzheimer's disease.

  7. Choroid plexus volume is associated with levels of CSF proteins: relevance for Alzheimer's and Parkinson's disease

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Neurobiology of aging 2020-01-16 Mild cognitive impairment

    The choroid plexus (ChP) is a major source of cerebrospinal fluid (CSF) production, with a direct and indirect role in protein clearance, and pathogenesis of Alzheimer's disease (AD).

    Why it matters

    In two large datasets, larger choroid plexus volume was associated with lower cerebrospinal fluid protein levels, and this association was weaker in late mild cognitive impairment and Alzheimer's disease patients and in amyloid-positive people. This supports a possible role for the choroid plexus in protein clearance but does not show that any treatment, cure, or prevention works.

  8. Dietary salt promotes cognitive impairment through tau phosphorylation

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Nature 2019-10-23 Prevention and risk

    Dietary habits and vascular risk factors promote both Alzheimer's disease and cognitive impairment caused by vascular factors 1-3 .

    Why it matters

    In mice, a salt-rich diet induced tau phosphorylation and cognitive dysfunction, and these effects were prevented by restoring endothelial nitric oxide production or by using anti-tau antibodies. This is animal research and does not yet show that reducing salt intake prevents dementia in humans.

  9. The MS4A gene cluster is a key modulator of soluble TREM2 and Alzheimer's disease risk

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Science translational medicine 2019-08-01 Genetics

    Soluble triggering receptor expressed on myeloid cells 2 (sTREM2) in cerebrospinal fluid (CSF) has been associated with Alzheimer's disease (AD).

    Why it matters

    In a genome-wide study of spinal-fluid samples from the Alzheimer's Disease Neuroimaging Initiative, common variants in the MS4A gene region were strongly linked to levels of soluble TREM2, a protein tied to the brain's immune cells (P = 1.15 × 10⁻¹⁵), and this was replicated in independent datasets. The variants that raised soluble TREM2 were associated with lower Alzheimer's risk and later onset, but the record gives no size for either effect. In human macrophages, used as a stand-in for brain immune cells, turning MS4A4A up raised soluble TREM2 and silencing it lowered it, which the authors say "suggest[s] that MS4A4A modulates sTREM2". No treatment was tested.

  10. Systemic inflammation impairs microglial Aβ clearance through NLRP3 inflammasome

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. The EMBO journal 2019-07-30 Inflammation and the immune system

    Alzheimer's disease is the most prevalent type of dementia and is caused by the deposition of extracellular amyloid-beta and abnormal tau phosphorylation.

    Why it matters

    This study reports that systemic inflammation is known to increase the risk for cognitive decline in human neurodegenerative diseases including Alzheimer's, and that microglia change shape once activated. It describes a mechanism involving the NLRP3 inflammasome but reports no treatment, cure or prevention result.

  11. Age-related hearing loss accelerates cerebrospinal fluid tau levels and brain atrophy: a longitudinal study

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Aging 2019-05-01 Long-term cohort studies

    Age-related hearing loss (ARHL) has been considered as a promising modifiable risk factor for cognitive impairment and dementia.

    Why it matters

    This study found that age-related hearing loss was associated with higher cerebrospinal fluid tau levels and brain atrophy over time. It does not show that treating hearing loss prevents dementia, and the findings are from an observational study of biomarkers.

  12. Immune Signaling in Neurodegeneration

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Immunity 2019-04-01 TREM2 and immune genetics

    Neurodegenerative diseases of the central nervous system progressively rob patients of their memory, motor function, and ability to perform daily tasks.

    Why it matters

    This is a review of immune signaling pathways, including TREM2, in neurodegeneration. It reports no new treatment, cure, or prevention for Alzheimer's disease.

  13. Genome-wide RNAseq study of the molecular mechanisms underlying microglia activation in response to pathological tau perturbation in the rTg4510 tau transgenic animal model

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Molecular neurodegeneration 2018-12-17 TREM2 and immune genetics

    Activation of microglia, the resident immune cells of the central nervous system, is a prominent pathological hallmark of Alzheimer's disease (AD).

    Why it matters

    This study profiled gene expression in microglia isolated from tau transgenic mice across four age groups to see what changes accompany microglial activation in response to tau pathology. It is animal research only and reports no treatment, cure or prevention for people.

  14. TREM2 - a key player in microglial biology and Alzheimer disease

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Nature reviews. Neurology 2018-11-01 Risk genes beyond APOE

    Alzheimer disease (AD) is a debilitating dementia believed to result from the deposition of extracellular amyloid-β (Aβ)-containing plaques followed by the formation of neurofibrillary tangles.

    Why it matters

    Variations in the TREM2 gene, which is expressed in microglia in the brain, have been shown to increase the risk of developing late-onset Alzheimer's disease. This identifies a genetic risk factor and a role for microglia, but it does not yet provide a treatment or cure.

  15. Serum neurofilament light chain in behavioral variant frontotemporal dementia

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Neurology 2018-09-12 Biomarkers

    As serum NfL correlates with functional impairment and brain atrophy in bvFTD at different disease stages, we propose it as marker of disease severity, paving the way for its future use as outcome measure for clinical trials.

    Why it matters

    In this study, serum neurofilament light chain was higher in people with behavioral variant frontotemporal dementia than in Alzheimer disease, mild cognitive impairment, or healthy controls, and it rose over time in bvFTD and AD. It correlated with functional decline and brain atrophy in bvFTD, but the study does not test any treatment, cure, or prevention.

  16. Microglial activation correlates in vivo with both tau and amyloid in Alzheimer's disease

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Brain : a journal of neurology 2018-09-01 Mild cognitive impairment

    Alzheimer's disease is characterized by the histopathological presence of amyloid-β plaques and tau-containing neurofibrillary tangles.

    Why it matters

    In people with mild cognitive impairment and Alzheimer's disease, brain imaging showed that microglial activation was correlated with both tau and amyloid accumulation. This suggests all three processes increase together, but the study does not show that targeting them prevents or treats the disease.

  17. TBK1 Suppresses RIPK1-Driven Apoptosis and Inflammation during Development and in Aging

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Cell 2018-08-23 Risk factors

    Aging is a major risk factor for both genetic and sporadic neurodegenerative disorders.

    Why it matters

    This mouse and human brain study found that aging reduces TAK1 expression, which cooperates with genetic risk factors to promote the onset of ALS/FTD, and that these features were blocked upon inhibition of RIPK1 in mice. These are early animal and tissue findings about ALS and frontotemporal dementia, not a treatment, cure or prevention for Alzheimer's disease.

  18. Promoting the clearance of neurotoxic proteins in neurodegenerative disorders of ageing

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Nature reviews. Drug discovery 2018-08-17 How common it is

    Neurodegenerative disorders of ageing (NDAs) such as Alzheimer disease, Parkinson disease, frontotemporal dementia, Huntington disease and amyotrophic lateral sclerosis represent a major socio-economic challenge in view of their high prevalence yet poor treatment.

    Why it matters

    This article discusses emerging mechanisms for promoting the clearance of toxic proteins as a possible way to delay the onset or slow the progression of neurodegenerative disorders including Alzheimer's disease. It is a discussion of strategy, not a tested treatment, cure or prevention.

  19. Brain-wide glymphatic enhancement and clearance in humans assessed with MRI

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. JCI insight 2018-07-12 How common it is

    To what extent does the subarachnoid cerebrospinal fluid (CSF) compartment communicate directly with the extravascular compartment of human brain tissue?

    Why it matters

    Using an injected tracer and MRI, this study showed that a substance given into the spinal fluid reached all regions of the human brain, and that its clearance was delayed in a group of patients with dementia. It is an early look at how fluid moves through the brain and does not test any treatment, cure or prevention.

  20. A lexical semantic hub for heteromodal naming in middle fusiform gyrus

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Brain : a journal of neurology 2018-07-01 Digital health tools

    We observed three stages of activity during both visual picture naming and auditory naming to definition that were serially organized: sensory processing, lexical semantic processing, and articulation.

    Why it matters

    This study mapped three stages of brain activity during naming tasks and identified brain regions involved in processing word meaning. It describes how the healthy brain handles language and does not test any treatment, cure, or prevention for Alzheimer's disease.

  21. Phase Separation of FUS Is Suppressed by Its Nuclear Import Receptor and Arginine Methylation

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Cell 2018-04-01 Lewy body dementia

    Cytoplasmic FUS aggregates are a pathological hallmark in a subset of patients with frontotemporal dementia (FTD) or amyotrophic lateral sclerosis (ALS).

    Why it matters

    This laboratory work identifies two mechanisms—Transportin binding and arginine methylation—that normally keep the FUS protein from clumping, and shows these are weakened in FUS-related FTD and ALS. It is early, cell-based research and does not test any treatment in patients.

  22. Description The American College of Physicians developed this guidance statement to guide clinicians in selecting targets for pharmacologic treatment of type 2 diabetes.

    Why it matters

    This guidance statement concerns blood sugar targets for treating type 2 diabetes in adults, not Alzheimer's disease. It recommends personalising glycemic goals and aiming for an HbA1c level between 7% and 8% in most patients.

  23. Vascular smooth muscle contraction in hypertension

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Cardiovascular research 2018-03-01 Risk factors

    Hypertension is a major risk factor for many common chronic diseases, such as heart failure, myocardial infarction, stroke, vascular dementia, and chronic kidney disease.

    Why it matters

    This review describes mechanisms of vascular smooth muscle contraction in hypertension, a condition listed as a risk factor for vascular dementia. It does not test or report any treatment, cure, or prevention for Alzheimer's disease.

  24. Rapid and ultra-sensitive quantitation of disease-associated α-synuclein seeds in brain and cerebrospinal fluid by αSyn RT-QuIC

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Acta neuropathologica communications 2018-02-09 Getting a diagnosis

    The diagnosis and treatment of synucleinopathies such as Parkinson disease and dementia with Lewy bodies would be aided by the availability of assays for the pathogenic disease-associated forms of α-synuclein (αSyn D ) that are sufficiently sensitive, specific, and practical for analysis of accessible diagnostic specimens.

    Why it matters

    This study describes an improved laboratory test that detects disease-associated alpha-synuclein seeds in cerebrospinal fluid in 1-2 days, with 93% sensitivity and 100% specificity in the samples tested so far. It is a diagnostic test for synucleinopathies such as Parkinson's disease and dementia with Lewy bodies, not a treatment or cure.

  25. Brain network efficiency is influenced by the pathologic source of corticobasal syndrome

    ✓ Peer-reviewed alzhub usefulness score 54 out of 100. Neurology 2017-08-04 Tau biomarkers

    In a cross-sectional design, pathology was confirmed by autopsy or a pathologically validated CSF total tau-to-β-amyloid ratio (T-tau/Aβ).

    Why it matters

    This study used brain imaging to look at how the source of nerve cell damage affects brain network efficiency in people with corticobasal syndrome, distinguishing Alzheimer's from non-Alzheimer's degeneration. It is a cross-sectional study and does not test any treatment or cure.
