Mortality risk after dementia diagnosis by dementia type and underlying factors: a cohort of 15,209 patients based on the Swedish Dementia Registry
Garcia-Ptacek S, Farahmand B, Kåreholt I, Religa D, Cuadrado ML, Eriksdotter M.. Journal of Alzheimer's disease : JAD, 2014-01-01
Topic: Risk, prevention and care in population studies
Background Knowledge on survival in dementia is crucial for patients and public health planning. Most studies comparing mortality risk included few different dementia diagnoses. Objectives To compare mortality risk in the most frequent dementia disorders in a large cohort of patients with an incident diagnosis, adjusting for potential confounding factors.
Key findings
- Most studies comparing mortality risk included few different dementia diagnoses.
- Objectives To compare mortality risk in the most frequent dementia disorders in a large cohort of patients with an incident diagnosis, adjusting for potential confounding factors.
- Methods 15,209 patients with dementia from the national quality database, Swedish Dementia Registry (SveDem), diagnosed in memory clinics from 2008 to 2011, were included in this study.
- The impact of age, gender, dementia diagnosis, baseline Mini-Mental State Examination (MMSE), institutionalization, coresidency, and medication on survival after diagnosis were examined using adjusted hazard ratios (HR) with 95% confidence intervals (CI).
Why it matters
Using 15,209 patients from the Swedish Dementia Registry, this study compared mortality risk after a dementia diagnosis by dementia type and other factors. It is about survival after diagnosis, not about treating, curing or preventing Alzheimer's disease.
