Very low proportion of deaths were associated with vascular dementia (4.9%) or other neurodegenerative diseases (5.3%). The AAMR increased in two distinct periods: a steep incline from 1999 to 2010 (APC: 6.95, 95% CI: 6.00–7.90), followed by a modest incline till 2020 (APC: 1.41, 95% CI: 0.80–2.04).

Timely identification of eligible patients is needed to ensure treatments are delivered during a narrow window of therapeutic opportunity. Appropriate clinical service design will hinge on improved understanding of future demands, thus there is a pressing need to investigate patient eligibility in real world clinical cohorts. The primary aim of this study is to assess the eligibility by appropriate use criteria (AUC) for lecanemab therapy in a real-world, undifferentiated clinical patient cohort attending a Regional Specialist Memory Clinic (RSMC), with the secondary aims of determining the proportion of patients with biomarker positive Alzheimer's Disease (AD) who would be eligible for lecanemab therapy by AUC.

Amyloid positivity was defined as either Amyloid and Tau positive (A+T+) or Amyloid positive with a positive P-Tau/Ab42 ratio on cerebrospinal fluid (CSF) testing.

The most common reason for exclusion was a lack of biomarker confirmation of AD pathology followed by cognitive ineligibility (based on defined cognitive testing cut-offs) at the time of referral and/or initial assessment.

Quality of life (QoL) is a multi-dimensional concept encompassing physical, spiritual, and emotional well-being. QoL aims to measure and quantify perceptions of individual health, well-being, standard of living, personal fulfillment, and satisfaction. As MBI symptoms may arise from early-stage neurodegenerative disease, MBI may contribute to declining QoL before dementia onset.

The concentration of contrast agents in different brain regions was measured, and the Patlak model was used to calculate <i>K</i>_trans. <i>K</i>_trans values were compared between the left and right cerebral hemispheres in different brain areas between the MSM and non-MSM groups.
