Description: This is a review of randomized controlled trials to determine the effectiveness of cognitive rehabilitation or cognitive training for people with dementia.

Question(s) Addressed:

Population: Participants with a medical diagnosis of dementia

Intervention/Assessment: Cognitive rehabilitation or cognitive training

Number of Studies Included: 6

Years Included: 1966 - 2003

Findings:

Conclusions:

  • Treatment
    • Cognitive-Communication
      • Restorative Treatments
        • Six studies were found examining the use of various cognitive training programs (e.g. stimulation, spaced retrieval, computer training) to improve memory performance.
        • The findings from the review did not show strong support for the use of targeted interventions with individuals presenting with early-stage Alzheimer's disease.
        • The authors concluded that "none of the six studies reporting cognitive training interventions demonstrated any statistically significant effects in any domain, although there were indications of some modest, non-significant effects in various domains of cognitive functioning" (p. 1).
        • Further research from randomized controlled trials is warranted.
