International cohort studies reveal that the brain starts to shrink, and neural connections to crumble, many years before FTD symptoms arise. Where and when those changes occur depends on the offending mutation.
The global platform trial for Alzheimer’s due to mutations in APP or presenilin will try to treat or prevent symptoms by deploying a therapeutic antibody that homes in on a piece of tau known to aggregate into neurofibrillary tangles.
As FTD consortia chase biomarkers, they see plasma NfL and neuronal pentraxin-2—which reflect neurodegeneration—change before symptoms. Trials nudge progranulin and poly-DP. Still needed: more markers of the pathophysiology that unfolds in the brain.
Grappling with a rare disease whose variability is daunting, international cohort studies are charting the natural history of FTD. They have discovered biomarkers and honed physiological tests that underlie its behavioral symptoms.
Merged Consortia Forge Path to Trials in Frontotemporal Dementia FTD Fluid Markers for Degeneration: Check. For Pathology: Not Yet. Imaging Exposes Hugely Heterogeneous Brain Changes Among FTDs Moving Target: Can Standardized Tests Track Symptoms of FTD? ...
Simple addition of choline, a phospholipid building block, ameliorated ApoE4-related deficiencies.
Already implicated in dementia, this lysosomal receptor appears to play a role in the development of COVID-19.
The more a person’s gut microbiome becomes individualized with age, the longer that person's lifespan and the better his or her health, say scientists.
White matter-associated microglia express similar genes to plaque-associated DAMs. They seem to be triggered by the myelin breakdown associated with aging and disease.
Whole-genome sequencing combined with expression data identifies five LBD loci: three known and two new. Four increased LBD risk while one appears protective.
Based on pooled data from five well-characterized cohorts, women appear to initially outperform men, but then slide faster, on global cognition and executive function. Oddly, this was not true for memory.
The commercial test uses a few drops of saliva. It must be ordered by a physician. Plans are also in the works to use the test to select participants for clinical trials.
Epidemiology study reveals 1.5-times higher risk of dementia after herpes virus infection. Short-term antiviral treatment appears to lower risk.
Researchers split $200,000 for their theories on the role of six microbes—one virus, four bacteria, and one parasite—in Alzheimer’s.
In mice, an anti-ApoE antibody removed plaques from the brain’s parenchyma and blood vessels better than aducanumab. Importantly, it caused no microhemorrhages.
