The objective of this study was to compare the effects of a multisensory stimulation environment (MSSE) and individualized music sessions on agitation, emotional and cognitive status, and dementia severity in a sample of institutionalized patients with severe dementia. Twenty-two participants with a diagnosis of severe or very severe dementia were randomly assigned to two groups: MSSE and individualized music sessions. Both groups participated in two 30-min weekly sessions over 16 weeks. Outcomes were agitation (Cohen-Mansfield Agitation Inventory, CMAI), mood (Cornell Scale for Depression in Dementia, CSDD), anxiety (Rating Anxiety in Dementia, RAID), cognitive function (Severe Mini-Mental State Examination, SMMSE), and the overall severity of dementia (Bedford Alzheimer Nursing Severity Scale, BANS-S). They were assessed at baseline (pre-trial), in the middle (mid-trial), at the end of the intervention (post-trial), and 8 weeks after the intervention (follow-up). Patients in the MSSE group showed significant improvement in their RAID and BANS-S scores compared with the individualized music group post- versus pre-trial. With regard to agitation, there was improvement during the intervention in both the MSSE and individualized music groups in the CMAI total score after 16 weeks of intervention, with no significant differences between the groups. The results suggest that MSSE could have better effects on anxiety symptoms and dementia severity in comparison with individualized music sessions in elderly patients with severe dementia.
Long-term effects of multisensory stimulation were assessed using a "Snoezelen" room on older residents with dementia. Thirty patients were randomly assigned to 3 groups: multisensory stimulation environment (MSSE) group, individualized activities (activity) group, and control group. The MSSE and activity groups participated in two 30-minute weekly individualized intervention sessions over 16 weeks. Pre-, mid-, posttrial, and 8-week follow-up behavior, mood, cognitive, and functional impairment in basic activities of daily living were registered. Items included in the physically nonaggressive behavior factor improved significantly in post- versus pretrial in the MSSE group compared to the activity group, with no significant differences between MSSE and control groups. The MSSE and activity groups demonstrated behavior improvements and higher scores on the Cohen-Mansfield agitation inventory, verbal agitated behavior factor, and Neuropsychiatric Inventory-Nursing Home, with no significant differences between groups. The MSSE could have long-term positive effects on such neuropsychiatric symptoms in older people with dementia.
The purpose of this study was to assess the effects of multisensory stimulation in a multisensory stimulation environment (MSSE) such as a Snoezelen room versus one-to-one activity sessions with regard to mood, behavior, and biomedical parameters (heart rate and blood oxygen saturation). The MSSE group and activity group (one-to-one activities) of patients with dementia participated in 2 weekly individualized intervention sessions over 16 weeks, where mood and behavior before, during, and after the sessions, and biomedical parameters immediately before and after, were recorded. Immediately after the sessions, patients spoke more spontaneously, related better to others, were more attentive to their environments, more active/alert, less bored/inactive, and more relaxed/content. Both groups exhibited decreases in heart rate and increases in oxygen saturation (Spo 2) values from before to after the sessions. The MSSE sessions in a Snoezelen room were found to be as effective as activity sessions, highlighting the importance of the one-to-one interaction with the therapist.
The objective of this study was to compare the effect of multisensory stimulation environment (MSSE) and one-to-one activity sessions in the symptomatology of elderly individuals with severe dementia. Thirty-two participants were randomly assigned to the following 3 groups: MSSE, activity, and control group. The MSSE and activity groups participated in two 30-minute weekly sessions over 16 weeks. Pre-, mid-, and posttrial; 8-week follow-up behavior; mood; cognitive status; and dementia severity were registered. Patients in the MSSE group demonstrated a significant improvement in the Neuropsychiatric Inventory and Bedford Alzheimer Nursing Severity Scale scores compared with the activity group. Both MSSE and activity groups showed an improvement during the intervention in the Cohen-Mansfield Agitation Inventory aggressive behavior factor and total score, with no significant differences between groups. The MSSE may have better effects on neuropsychiatric symptoms and dementia severity in comparison with one-to-one activity sessions in patients with severe dementia.
