Fluid AD Biomarkers Link P-Tau to Synapses, Inflammation
An expanded set of CSF biomarkers exposed tight connections between p-tau, synaptic dysfunction, and neuroinflammation in people with brain amyloid.
Could New Glutamate Receptor Activators Treat Alzheimer’s?
Positive allosteric modulators improve learning and memory in mouse models of AD and epilepsy.
Tangle Density Foretells How Fast a Person’s Brain Will Shrink
In early Alzheimer’s disease, the pattern of tau deposition also strongly predicts areas destined for subsequent degeneration.
Paper Alert: Lipid Droplet-Filled Microglia Harm the Brain
These oily microglia resemble the foamy macrophages seen in atherosclerotic plaques. They correlate with aging, inflammation, and neurodegenerative disease.
In AD, Chaperones Congregate To Form a Therapeutic Target
Aberrant protein-protein interactions centered on HSP90 may contribute to Alzheimer’s disease. Can an inhibitor set things right?
Soccer Heading Has Greater Impact on Memory in ApoE4 Carriers
Frequent heading weakened verbal memory in amateur soccer players, and more so in ApoE4 carriers.
Does Young-Onset Parkinson’s Arise in Lysosomes?
Poor lysosomal function in dopaminergic neurons derived from people with YOPD points to disease origin and potential therapies.
Tau PET Scans Turn Positive When Amyloid Does; Symptoms Follow
Data from different next-generation tracers look similar. It shows spreading plaques kick off tangles by Braak region; memory starts slipping later.
Multimodal Imaging of Neurodegenerative Diseases Links Pathology and Cellular Dysfunction
Synapse loss and mitochondrial stress, as seen by separate PET tracers, go hand-in-hand in Alzheimer’s, Parkinson’s, and frontotemporal dementia.
Paper Alert: Phase 3 Trial Data Published on Sleep Aid Suvorexant
FDA approves adding safety and efficacy data from an Alzheimer’s trial to the drug’s label.
New Myelin Makes Memories, but Supply Wanes with Age
The creation of long-term memories requires a continual supply of myelin provided by newly formed oligodendrocytes. Alas, the generation of fresh oligodendrocytes diminishes with age, along with memory.
Retinal Gene Therapy Trial Posts Positive Result
Vision improved in some retinitis pigmentosa patients in a Phase 1 trial.
PET Tracer Detects Synapse Loss Across Alzheimer’s Brain
New research presented at the HAI conference also finds links between UCB-J uptake and plaques, tangles, and cognitive decline.
Can PET Match Up Areas of Protein Deposit With Alzheimer’s Symptoms?
Amyloid and tau PET are helping scientists pinpoint the underlying cause of specific AD symptoms. Perhaps imaging of certain brain regions will help predict an individual’s progression.
