Tau PET: The Field Expands Rapidly
At the HAI 2020 conference, the tracers PI-2620 and APN-1607 appeared to bind frontotemporal dementia tau. MK-6240 looked highly sensitive. And JNJ-067 and SNFT-1 are two new kids in town.
GABA-A Receptor Structures Point to Drug Mechanisms
CryoEM helps explain how the inhibitory receptors open and close their ion channels.
Liver Enzyme Levitates with Exercise, Spurs Learning in Old Mice
The findings hint at a liver-brain axis that transmits inflammation from periphery to brain, and could suggest therapeutic targets for preserving brain function.
PET Tracer PI-2620 Detects 4R Tau Deposits
The tracer distinguished people with progressive supranuclear palsy from controls with a sensitivity of 85 percent, suggesting potential as a diagnostic for 4R tauopathies.
Cell-Type-Specific RNA Analysis Probes Selective Vulnerability in Huntington’s
In striatal spiny projection neurons with mutant huntingtin, mitochondria spill immunogenic RNAs into the cytosol. These touch off innate antiviral signaling inside the neurons, which may spell their demise.
IDEAS Finds Small Drop in Hospitalizations, Missing Goal
A slight drop in hospital admissions after amyloid PET, especially in people with positive scans, fell well short of the prespecified endpoint. Still, IDEAS is broadening into a research platform, and IDEAS 2 will add racial diversity.
Potential Parkinson’s Treatments Target α-Synuclein, Cell Replacement
Two drugs that boost α-synuclein clearance have passed Phase 1 safety benchmarks, and a stem cell strategy is poised to enter trials, reported scientists at SfN 2015.
Lancet Commission’s Dementia Hit List Adds Alcohol, Pollution, TBI
In updating their broad evaluation of the risk literature, the commission blamed three more modifiable factors for causing 6 percent of all dementia, concluding that 40 percent of cases can be prevented.
Heart Health Is Brain Health, and It Starts in Your 20s
New research pushes back the age at which dementia risk from cardiovascular and metabolic factors begins. Should protective lifestyle interventions start in youth?

Plasma p-Tau217 Set to Transform Alzheimer’s Diagnostics Could Common Vaccines Protect Against Alzheimer’s Disease? Doubling Down on Sequencing Serves up More Alzheimer’s Genes IDEAS Finds Small Drop in Hospitalizations, Missing Goal Lancet Commission’s ...
Confused About the DIAN-TU Trial Data? Experts Discuss
The AAT-AD/PD conference hosted a virtual conversation about what the trial’s disappointing cognitive and tantalizing biomarker data might mean. Hidden between thank you’s and pledges to stay committed were substantive points of debate and context.
Umibecestat-Driven Cognitive Decline Is Reversible
Subtle memory deficits resolved after volunteers stopped taking the Novartis BACE inhibitor.
At AAIC, Hints of Target Engagement for Some Drug Candidates
Early data suggest that CT1812 and AL001 shift biomarker levels in Alzheimer’s disease and frontotemporal dementia, respectively. BI 425809 fails to improve cognition.
NEALS: Collaboration for a Cure to ALS
In the field of amyotrophic lateral sclerosis (ALS), the Northeast ALS Consortium (NEALS) is the hands-down largest and hardest-working township in North America...
