Importance: Early identification of Alzheimer disease (AD) is important for clinical management and affords the opportunity to assess potential disease-modifying agents in clinical trials. To our knowledge, this is the first report of a randomized trial to prospectively enrich a study population with prodromal AD (PDAD) defined by cerebrospinal fluid (CSF) biomarker criteria and mild […]
Diagnostic performance of cerebrospinal fluid total tau and phosphorylated tau in Creutzfeldt-Jakob disease: results from the Swedish Mortality Registry

Blennow, Kaj,
Zetterberg, Henrik
Importance: Identifying a clinical distinction between the invariably lethal prion disease Creutzfeldt-Jakob disease (CJD) and nonprion rapidly progressive dementias is important and sometimes difficult; thus, reliable tools for diagnosis are in great demand.; Objective: To test the diagnostic performance of dementia cerebrospinal fluid (CSF) biomarkers total tau (T-tau), phosphorylated tau (P-tau), and the T-tau to […]
Effect of 1 night of total sleep deprivation on cerebrospinal fluid β-amyloid 42 in healthy middle-aged men: a randomized clinical trial
Ooms, Sharon,
Overeem, Sebastiaan,
Besse, Kees,
Rikkert, Marcel Olde,
Verbeek, Marcel,
Claassen, Jurgen A. H. R.
Importance: Increasing evidence suggests a relationship between poor sleep and the risk of developing Alzheimer disease. A previous study found an effect of sleep on β-amyloid (Aβ), which is a key protein in Alzheimer disease pathology.; Objective: To determine the effect of 1 night of total sleep deprivation on cerebrospinal fluid Aβ42 protein levels in […]
Population screening for variant Creutzfeldt-Jakob disease using a novel blood test: diagnostic accuracy and feasibility study

Collinge, John
Importance: Our study indicates a prototype blood-based variant Creutzfeldt-Jakob disease (vCJD) assay has sufficient sensitivity and specificity to justify a large study comparing vCJD prevalence in the United Kingdom with a bovine spongiform encephalopathy-unexposed population. In a clinical diagnostic capacity, the assay’s likelihood ratios dramatically change an individual’s pretest disease odds to posttest probabilities and […]
The preclinical Alzheimer cognitive composite: Measuring amyloid-related decline
Donohue, Michael C.,
Sperling, Reisa A.,
Salmon, David P.,
Rentz, Dorene M.,
Raman, Rema,
Thomas, Ronald G.,
Weiner, Michael,
Aisen, Paul S
Importance: As Alzheimer disease (AD) research moves to intervene in presymptomatic phases of the disease, we must develop outcome measures sensitive to the earliest disease-related changes. Objective: To demonstrate the feasibility of a cognitive composite outcome for clinically normal elderly participants with evidence of AD pathology using the ADCS Preclinical Alzheimer Cognitive Composite (ADCS-PACC). The […]
