Predictors of non-bedridden survival in dementia

The present study examined non-bedridden survival in 105 patients diagnosed as demented (Alzheimer's disease, multi-infarct dementia, mixed dementia) in a neurological ward. Follow-up observations were made. During the first year, the cumulative mortality rate was 69% compared to a rate of 44% in the second year. The initial disability stage, as assessed by the Dementia Disability Scale, was found to be the only significant predictor of non-bedridden survival. The type of dementia, age, type of diagnosis, and post-hospitalization placement in an institution have not been found to be significant predictors of this evolution.
