Brief Summary

Individuals with dementia present with changes in behaviors throughout the continuum of cognitive decline. Environmental features may be influential in behavioral regulation. The purpose of this study is to assess the feasibility of environmental design protocols in older adults with dementia and their caregivers. Thirty subjects with moderate to severe Alzheimer's disease as primary dementia type, and their caregivers, will be randomly assigned to one of three arms: standard care; standard environmental design protocol; or personalized environmental design protocol.

Study Arms (3)

Control Group

PLACEBO COMPARATOR

Alzheimer's disease patients and caregivers.

Behavioral: Placebo

Standard Environmental Design

EXPERIMENTAL

Alzheimer's disease patients and caregivers.

Behavioral: Standard Environmental Design

Individualized Environmental Design Protocol

EXPERIMENTAL

Alzheimer's disease patients and caregivers.

Behavioral: Individual Environmental Design

Interventions

Participants' caregivers will receive set script of physical environmental modifications (i.e., declutter living space, reduce background noise, increase natural light), and social environment training script will include caregiving techniques: training for calming demeanor (emotional contagion), needs-driven care to decrease behavioral disruption, and accepting and accommodating approach to behavioral disruption. A pre-selected sensory stimulation kit will be provided to each participants' caregiver for administration throughout the day.

Standard Environmental Design

Participants' caregivers will receive set script of physical environmental modifications and social environment training script in a standard protocol. Following initial assessments, individualized sensory stimulation kits will be developed using subjects' preferred sensory stimuli (as determined by the Adult Sensory Profile assessment and informant report) and will be provided via caregiver administration throughout the day to promote maintained behavioral regulation.

Individualized Environmental Design Protocol
PlaceboBEHAVIORAL

Participants' caregivers will receive a set script of placebo modifications.
