some aspects of sleep and activity
rhythmicity. No clear evidence
of efficacy was found
for agitation and depression.
No evidence shows the efficacy
of Snoezelen for treatment
of dementia.
6 of the 7 studies with people
with dementia reported positive
within-session effects on
communication, engagement
and self-injury measures. All
studies reported inconclusive
long-term effects.
Adverse effects were not considered.
Sample sizes were
small.
Meta-analyses could not be
performed because of the limited
number and different
study methods of the available
trials.
Sample sizes were small. Outcome
measures were heterogeneous
and most were observational.
