    According to new research, oestrogen therapy in postmenopausal women is associated with ventricular enlargement and increased white matter hyperintensities in the brain, but not with cognitive decline. This disconnect between structural and functional effects suggests that brain-derived lipids can be harnessed to meet the bioenergetic demand imposed by normal cognition.

    A new study suggests that the application of uniform diagnostic criteria for mild cognitive impairment (MCI) substantially reduces variation in MCI prevalence estimates. Refinement and harmonization of clinical and research criteria are essential milestones towards improved testing of therapeutic interventions aimed at curbing the epidemic of MCI and dementia.

    Suspected non-Alzheimer disease pathophysiology (SNAP) is a biomarker-based concept that applies to individuals with normal levels of amyloid-β biomarkers in the brain, but in whom biomarkers of neurodegeneration are abnormal. Clinically normal and mildly impaired individuals with SNAP are at increased risk of poor clinical and cognitive outcomes. In this Perspectives article, Clifford Jack and colleagues describe the available data on SNAP and address topical controversies in the field.
