Summary
Mortality in Alzheimer's disease (AD) is primarily linked to patient age and cognitive decline severity. Other factors like gender or genetics did not significantly impact survival rates in this study.
Area of Science:
- Neurology
- Gerontology
- Epidemiology
Background:
- Alzheimer's disease (AD) is a progressive neurodegenerative disorder.
- Understanding factors influencing mortality in AD is crucial for patient care and resource allocation.
Purpose of the Study:
- To investigate variables associated with mortality risk in individuals diagnosed with Alzheimer's disease.
- To identify key predictors of survival in an AD cohort.
Main Methods:
- A cohort of 172 Alzheimer's disease (AD) subjects was followed for an average of 4.7 years.
- Survival analysis was performed using Kaplan-Meier and log-rank tests.
- Cox proportional hazards models identified mortality predictors.
Main Results:
- Increased mortality risk in AD patients was significantly associated with older age, greater cognitive impairment severity, and hospitalisation incidence.
- Factors such as gender, illness duration, cognitive decline velocity, APOE E4 genotype, and comorbid psychiatric diagnoses did not significantly influence mortality.
Conclusions:
- Age and the severity of cognitive impairment are the primary determinants of mortality in Alzheimer's disease.
- These findings highlight the importance of managing cognitive decline and related health issues to improve survival outcomes in AD patients.
