From more than 45,000 MRI scans, a typical pattern of brain aging emerges. Brains “age” faster in people who have a neurological disorder.
The G2019S variant that boosts Parkinson’s risk helps mice survive infection, but raises α-synuclein in the brain and increases neuronal death.
The circular transcripts correlate with AD pathology and dementia severity, suggesting potential roles in pathogenesis or as biomarkers.
The transcriptional repressor quiets neural activity and lengthens lifespan in worms. It is abundant in the brains of cognitively healthy centenarians.
The field is searching for a combination of clinical features and biomarkers that will identify the disease in people with mild cognitive impairment.
Middle-aged people who exercise more are less likely to become amyloid-positive. In late life, people with brain amyloid who exercise declined more slowly and had less brain shrinkage over the following years.
RPS25 helps translate repetitive snippets of RNA that are associated with neurodegenerative diseases. Knocking it down reduces protein aggregates and cell death.
Too much or too little serum hemoglobin increases risk for Alzheimer’s and other dementias by 20 percent or more.
The DIAN Trials Unit is nearing the end of its first two secondary prevention trials. It has begun a cognitive run-in period for its next trial, of a tau-based drug, and for a primary prevention study in people as young as 18.
As the Alzheimer’s field suffers smackdowns in trials of small molecules and antibodies, antisense oligonucleotides are quietly coming along—and looking safe so far.
A brother’s survival guilt, a journalist tracing her mutation to Lebanon, a student freezing her eggs ahead of a primary prevention trial—DIAN family members are stirring their growing community to act against Alzheimer’s disease.
ApoE2 homozygotes have a dramatically lower risk of AD than even the previously known low-risk E2/3 heterozygotes. More study of this protective allele could reveal roots of resilience.
Nearly 30 years after the first Alzheimer’s gene discoveries, genetics once again drives recruitment, scientific progress, and therapy development in the Dominantly Inherited Alzheimer’s Network.
At AAIC, researchers presented baseline data from an ongoing, five-year study asking whether the anti-Aβ antibody crenezumab can forestall cognitive decline in autosomal-dominant Alzheimer’s disease.
DIAD: Families from Argentina, Canada, Minnesota Rally a Global Community Genetics Propels DIAN Toward Therapies ASOs: Wave of the Future in Alzheimer’s Therapeutics? As DIAN Wraps Up Anti-Aβ Drug Arms, it Sprouts Tau, Primary Prevention Arms On July 13, ...
