Besides cushioning the brain, CSF washes away waste such as neurotransmitters, metabolites, and proteins, including proteins that aggregate—such as Aβ and tau. After circulating through the brain, CSF ...

Cytotoxic T cells are star players in the adaptive immune system, enforcing protection against invading viruses or cancer cells. However, evidence has been mounting that the cells may also deal a ...

For years, scientists have been working toward blood tests for Alzheimer’s disease that could be used routinely in clinical practice. Now, they are on the cusp. At this year’s ADPD conference, held ...

Of the 20,000+ human genes, none has greater influence on late-onset Alzheimer’s disease than APOE. But why do certain variants of this lipid transporter protect the brain, while others endanger it? A ...

Most Alzheimerologists agree that lecanemab and donanemab are a start, but insufficient to treat this disease. At the Clinical Trials in Alzheimer’s Disease conference, held last month in Madrid, ...

Old drugs die hard. Despite a string of negative Phase 3 trials, HMTM, a derivative of the malaria drug methylene blue, resurfaced again at AD/PD 2024, held March 5-9 in Lisbon, Portugal. TauRx CEO ...

Not so long ago, a blood test for Alzheimer’s disease seemed a pipe dream. Now, after years of study, the field is awash with sensitive assays that signal the proteopathic culprits Aβ and tau ...

Fox added that peer-reviewed studies are needed to fully understand the sensitivity and specificity of the approach. One preprint, and findings presented at CTAD conferences in 2020 and 2021, suggest ...

All Signs Point to Plaque Clearance Tangle accumulation has slowed in all successful anti-amyloid antibody trials so far—except in the Trailblazer-Alz2 study of donanemab. That trial posted the ...

People with ApoE3 Christchurch variant stave off even autosomal-dominant Alzheimer’s disease by keeping neurofibrillary tangles at bay. Could people born without this protective mutation reap its ...

However, diagnostic tests do not need FDA approval to be marketed to the public. They can clear a lower bar by becoming CLIA-approved, meaning the assay has good test-retest reproducibility. Quest's ...

How does gene expression in the brain change with age? The answer remains murky, because the field has lacked a systematic, brain-wide survey of alterations across the lifespan. Researchers led by ...
