Do blood components really leak across an inflamed blood-brain barrier early on in the development of Alzheimer’s disease? Some GWAS hits and budding neuro-imaging and fluid markers are helping researchers find out.
Baby Boomers, keep your blood pressure down. Research is beginning to explain how even mild hypertension, a mid-life risk factor for late-life dementia, might be damaging the neurovascular unit.
Marek-Marsel Mesulam received the prestigious award for his research on primary progressive aphasia, a language disorder that can affect people with Alzheimer’s or frontotemporal dementia.
Scientists generate human embryonic stem cell lines from adult donor cells, building on earlier studies that showed this was possible with fetal cells.
Scientists claim that AV-133, an imaging agent that visualizes dopaminergic neurons, can gauge progression of Parkinson’s disease.
Tirasemtiv, a drug thought to make muscles more sensitive to signals from motor neurons, failed to improve muscle function in people with amyotrophic lateral sclerosis.
New research suggests that dendritic tau may participate in synaptic plasticity, and that Aβ disrupts this function.
Nucleotide repeat expansions in the C9ORF72 gene occur in amyotrophic lateral sclerosis and frontotemporal dementia. Now researchers find the same repeats in patients with two other neurological disorders.
A drug candidate for Alzheimer’s aims to make cell trafficking more efficient, reduce Aβ production.
A new study charges that, contrary to previous studies, seeding the mouse brain with aggregated α-synuclein does not trigger a toxic spread of PD-like inclusions in wild-type mice.
Scientists had the good fortune to study the exceedingly rare instance of a pair of identical twins, only one of whom had Trisomy 21. It turned out that gene regulation was altered across the entire genome in the twin with Down’s syndrome.
Allegations of scientist misconduct led to the retraction of one high-profile stem cell paper and put two others in doubt.
A small molecule inhibitor kills all microglia in the brain, but the cells rapidly repopulate from a previously unidentified progenitor cell.
If new results hold up, enhanced phosphorylation of a ribosomal protein may explain the toxicity of mutations that cause Parkinson's.
A new bill will centralize the approval process for multinational trials and mandate the publication of trial results—good or bad.
