In a retrospective study, people with vitiligo had 12 times the risk of developing Alzheimer’s disease than did healthy controls. Why is that?
This pathway may transmogrify microglia during neurodegeneration, without the help of TREM2.
Sensor algorithms can accurately capture patterns of resting tremor and dyskinesia. This could help clinicians manage symptoms and medication.
People who report not participating in social or cognitive activities are more likely to develop dementia within the next few years, but not after that. The findings cast nonparticipation as a consequence, not a cause, of neurodegeneration.
Transcriptomic and epigenomic data pin PD risk genes in GWAS loci; six affect splicing, five expression, four are new.
Researchers envision p-tau-based blood tests for Alzheimer’s disease within a few years, but maybe not a stand-alone test.
Two mouse models presented at AD/PD may hand scientists more translationally relevant tools to explore LOAD pathophysiology and treatment. The tricks: targeted replacement and knocking in multiple GWAS variants.
New research implicates IL-6 signaling and even Aβ42 itself as BACE targets, complicating efforts to resurrect BACE inhibitors at a low dose.
After news on “new data” they won’t see, three committee members argue against approval.
The field is shifting from targeting tau’s tips to its mid-region, especially where tau binds microtubules. Several new candidates are in the clinic; whether the strategy will work remains to be seen.
In a mouse model of amyloidosis, human wild-type TREM2 kept Aβ deposition at bay early on, but this defense became overwhelmed as plaques grew. The R47H AD risk variant never offered protection early on, and made things worse later.
For several neurodegenerative diseases, scientists identified which cell types exert a person’s inherited risk. In Alzheimer’s, it’s microglia; in Parkinson’s, it’s dopaminergic and enteric neurons—and oligodendrocytes.
Trialists are shooting new arrows at the disease, including compounds that tweak autophagy, neuroinflammation, and glycolipid recycling.
Chemicals and particulates may slip across the blood-brain barrier or travel up olfactory nerves to directly affect brain cells. What are the consequences for cognition?
Growing evidence suggests exposure to air pollution increases risk of brain damage and dementia. More definitive research is needed.
