The SIB has become a benchmark assessment used extensively in worldwide clinical trials by drug companies seeking to develop treatments to combat Alzheimer’s disease.


  • The SIB gathers direct performance-based data on a wide variety of low-level tasks which take into account the specific behavioural and cognitive deficits associated with severe dementia
  • Enhances our understanding of the disease process and provides valuable clinical information regarding the later stages of dementia
  • Evaluates cognitive abilities at the lower end of the range


  • It is composed of simple one-step commands and gestural cues, and it allows for a variety of simple responses
  • Brief evaluations of praxis, social interaction and orienting to name

The six major subscales are:

  • Attention
  • Orientation
  • Language
  • Memory
  • Visuo-spatial ability
  • Construction
