title: Emotional reactivity to film material in Alzheimer's disease.
abstract: OBJECTIVE
  To explore emotional reactivity in mild to moderate Alzheimer's disease (AD) using film material, investigating the influence of dementia-related material and awareness of condition.
  
  
  METHODS
  Twenty-two patients with AD and 21 healthy older adults viewed films with positive, neutral or negative content, including a film about dementia. Reactivity was measured through a self-report questionnaire and filming of facial expressions. Awareness of condition was assessed contrasting patients' versus informants' versions of an anosognosia questionnaire.
  
  
  RESULTS
  The AD patients showed reduced self-reported reactivity to negative films, but exhibited a pattern of facial responses similar to controls for all films. Awareness was associated with frequency of negative facial expressions during the dementia film.
  
  
  CONCLUSIONS
  AD patients may have impairments in self-reported reactivity to negative stimuli. Awareness may mediate responses to dementia-related material.
