Diagnosis of Alzheimer's Dementia and Vehicle Driving Restriction: A Scoping Review

This scoping review examined literature (2000-2022) on driving safety and restrictions for patients with Alzheimer's disease and cognitive decline, finding no sufficiently sensitive psychometric tests to reliably assess driving competence in older adults with cognitive deficits. The authors conclude there is insufficient robust evidence to recommend either continuation or cessation of driving for patients with mild cognitive impairment or mild dementia, while noting driving restrictions can significantly impact patients and families, and that legal regulations on this issue are sparse globally

Mechanisms linking cerebrovascular dysfunction and tauopathy: Adding a layer of epiregulatory complexity

This review examines how tau protein misfolding and accumulation impair blood-brain barrier integrity and vascular function in Alzheimer's disease and other tauopathies, while also exploring how cerebrovascular dysfunction promotes tau pathology. The authors highlight epigenetic and epitranscriptomic mechanisms regulating cerebrovascular integrity and tauopathy progression, with implications for therapeutic intervention.

Longitudinal trajectories of cognitive reserve in hypometabolic subtypes of Alzheimer's disease

This study examined how cognitive reserve—the brain's ability to maintain function despite Alzheimer's pathology—differs between typical and limbic-predominant subtypes of Alzheimer's disease using neuroimaging data from over 500 participants. Results showed that higher cognitive reserve predicted slower cognitive decline, with typical Alzheimer's subtype showing faster reserve deterioration than the limbic-predominant form, highlighting the importance of subtype-specific analyses in understanding disease progression.

Expert Consensus on Amyloid-PET Imaging for Alzheimer's Disease Diagnosis

This expert consensus addresses the clinical application of amyloid positron emission tomography (PET) as a standardized tool for early detection of Alzheimer's disease pathology, which precedes cognitive symptoms. The document recommends binary interpretation (positive/negative) of amyloid-PET results combined with clinical assessment, neuropsychological testing, and other imaging biomarkers for reliable diagnosis and treatment evaluation.

German UCSF Brain Health Assessment Shows High Sensitivity for Early Neurodegenerative Disorders

A validation study of the tablet-based UCSF Brain Health Assessment (BHA) and Brain Health Survey (BHS) in German-speaking patients found these tools highly accurate at detecting mild neurocognitive disorder and non-Alzheimer's presentations, with greater sensitivity than the Montreal Cognitive Assessment. The combined instrument achieved 95% accuracy for mild neurocognitive disorder and 96% accuracy for non-amyloid pathology cases, suggesting potential for earlier identification in primary care settings.
