This is a systematic review of systematic reviews examining the use of various nonpharmacological interventions for individuals with dementia. A variety of psychosocial, behavioral, cognitive and caregiver support interventions were included and described, a portion of which were within the scope of speech-language pathology.

Number of Studies Included
Evidence Ratings for This Document
Evidence was rated based on the number and quality of relevant included reviews. The rating scale in this paper was based off of methods from both the Cochrane Collaboration and the Oxford Centre of Evidence-Based Medicine. Levels of evidence are defined as follows:
- Level 1: 'Sufficient evidence', or "consistent evidence from high, moderate quality, or reviews of specific interventions" (p. 2851)
- Level 2: 'Some evidence', or less consistent high or moderate quality reviews, or a majority of reviews/studies in favor of intervention
- Level 3: 'Insufficient evidence', or conflicting results, or evidence suggesting ineffectiveness
- Level 4: 'Insufficient evidence to determine', or lack of primary studies or information
Conclusions from This Systematic Review
What are Conclusions?
Go to Map
There was insufficient evidence (Level 3) to support the use of validation therapy for individuals with dementia.
There was level 2 evidence from six systematic reviews supporting the use of reminiscence treatment, sensory stimulation and activities of daily living training with individuals with dementia.
Six systematic reviews provided level 1 evidence for the use of cognitive stimulation and cognitive training (e.g., memory aid training) to improve the cognitive skills of individuals with early-stage dementia.
