title: Quality of life of patients with Korsakoff's syndrome and patients with dementia: a cross-sectional study.
abstract: OBJECTIVE
  Korsakoff's syndrome (KS) is a chronic disorder caused by thiamine (vitamin B1) deficiency and alcoholism. The disorder is characterized by severe amnesia and often compared with dementia. The purpose of this study was to compare the quality of life between patients with KS and patients with dementia from the same nursing homes.
  
  
  METHODS
  Cross-sectional study design.
  
  
  METHODS
  Three nursing homes in the Netherlands.
  
  
  METHODS
  Participants were 72 patients diagnosed with KS and 75 patients diagnosed with dementia through extensive neuropsychological evaluation and multidisciplinary diagnostics.
  
  
  METHODS
  Quality of life (QoL) was scored with the QUALIDEM scale. Multivariate linear regression analysis was used to compare QoL between patients with KS and patients with dementia, applying the covariates "age," "gender," and "nursing home."
  
  
  RESULTS
  Of the 147 included patients, 72 (48.9%) were diagnosed with KS. Overall QoL was higher in KS. Patients with KS scored better than patients with dementia on the QUALIDEM subscales "Restless tense behavior," "Social relations," and "Having something to do." A trend toward a better score was found for the subscale "Positive affect"; a trend toward a lower score was found for "Feeling at home."
  
  
  CONCLUSIONS
  KS is associated with profound differences in QoL compared with dementia. Patients with KS tend to have more social relationships and more positive emotions than patients with dementia. Furthermore, patients with dementia show more restless behavior than patients with KS; however, patients with KS tend to feel less at home in a nursing home than patients with dementia. Results suggest that both patients with dementia and patients with KS are in need of specialized nursing homes and care programs to accomplish their specific needs.
