    • We investigated the use of Alzheimer's disease (AD) biomarkers in European Alzheimer's Disease Consortium centers and assessed their perceived usefulness for the etiologic diagnosis of mild cognitive impairment (MCI). We surveyed availability, frequency of use, and confidence in diagnostic usefulness of markers of brain amyloidosis (amyloid positron emission tomography [PET], cerebrospinal fluid [CSF] Aβ42) and neurodegeneration (medial temporal atrophy [MTA] on MR, fluorodeoxyglucose positron emission tomography [FDG-PET], CSF tau). The most frequently used biomarker is visually rated MTA (75% of the 37 responders reported using it "always/frequently") followed by CSF markers (22%), FDG-PET (16%), and amyloid-PET (3%). Only 45% of responders perceive MTA as contributing to diagnostic confidence, where the contribution was rated as "moderate". Seventy-nine percent of responders felt "very/extremely" comfortable delivering a diagnosis of MCI due to AD when both amyloid and neuronal injury biomarkers were abnormal (P < .02 versus any individual biomarker). Responders largely agreed that a combination of amyloidosis and neuronal injury biomarkers was a strongly indicative AD signature.

  • Evidence-based evaluation of magnetic resonance imaging as a diagnostic tool in dementia workup
  • 2005
  • Ingår i: Topics in Magnetic Resonance Imaging. - : Ovid Technologies (Wolters Kluwer Health). - 0899-3459. ; 16:6, s. 427-437
  • Forskningsöversikt (refereegranskat)abstract
    • BACKGROUND: The diagnostic utility of magnetic resonance imaging in dementia workups has increased recently. The basic use is to exclude space-occupying processes in the brain. However, magnetic resonance imaging offers major opportunities for studying atrophy of specific brain areas. A great interest has been put in whether atrophy in the medial temporal lobe can serve as an early diagnostic marker for Alzheimer disease. METHODS AND RESULTS: In this evaluation, we used evidence-based techniques and reviewed more than 400 articles that address this issue. Our main finding is that a variety of methods in studying brain areas were used, and this made it difficult to extract conclusive information in a systematic way. CONCLUSION: However, we were able to conclude that atrophy of the hippocampus can distinguish patients with Alzheimer disease from healthy subjects, but there was a lack of evidence because of insufficient studies concerning the usefulness of medial temporal lobe atrophy as a diagnostic marker in a more general setting.
