Long-term follow-up study examines cognitive and clinical factors affecting survival in Alzheimer's patients, indicating the need for intervention.

The aim is to identify cognitive and clinical predictors of survival time in Alzheimer's disease dementia patients.
Conducted a long-term retrospective study following 202 patients from initial ADD diagnosis to death.
Used hierarchical clustering to determine cognitive clusters based on neuropsychological exam results.
Applied Cox regression analysis to assess the impact of cognitive clusters and clinical variables on survival time.
Higher age (HR = 1.04) and lower baseline MMSE score (HR = 0.92) were linked to shorter survival times.
Pre-diagnosed atrial fibrillation (HR = 2.06) and delirium (HR = 3.13) significantly predicted mortality.
Patients in the mixed cluster had shorter survival times (HR = 1.45) compared to the amnestic cluster.

Doganyigit et al. (2026) studied this question.
