What affects pleasure in persons with advanced stage dementia?

We examined the impact of environmental, person, and stimulus characteristics on pleasure in persons with dementia. Study participants were 193 residents of 7 Maryland nursing homes who were presented with 25 stimuli from these categories: live human social stimuli, live pet social stimuli, simulated social stimuli, inanimate social stimuli, a reading stimulus, manipulative stimuli, a music stimulus, task and work-related stimuli, and two different self-identity stimuli. Systematic observations of pleasure in the natural environment were conducted using Lawton's Modified Behavior Stream. Analysis showed that pleasure is related to stimulus category, personal attributes and environmental conditions. In the multivariate analyses, all types of social stimuli (live and simulated, human and nonhuman), self-identity stimuli, and music were related to significantly higher levels of pleasure than the control condition. Females and persons with higher ADL and communication functional status exhibited more pleasure. Pleasure was most likely to occur in environments with moderate noise levels. These results demonstrate that these nursing home residents are indeed capable of showing pleasure. Caregivers of nursing home residents with dementia should incorporate social, self-identity, and music stimuli into their residents' care plans so that eliciting pleasure from each resident becomes the norm rather than a random occurrence.

The impact of different dog-related stimuli on engagement of persons with dementia.

OBJECTIVE: To provide further empirical evaluation of the effectiveness of animal-assisted therapy in nursing home residents with dementia. METHODS: Participants were 56 residents of 2 suburban Maryland nursing homes and had a diagnosis. Activities of daily living performance was assessed via the minimum data set and cognitive functioning assessed using the Mini-Mental State Examination. Engagement with dog-related stimuli was systematically assessed via the observational measurement of engagement. RESULTS: Mean engagement duration was significantly lower for the small dog. Highest mean engagement duration was found for the puppy video, followed by the real dog and lowest was for the dog-coloring activity. Positive attitudes were found toward the real dogs, robotic dog, the puppy video, and the plush dog. No significant differences were found in engagement duration among our dog-related stimuli. CONCLUSIONS: Nursing homes should consider animal-assisted therapy and dog-related stimuli, as they successfully engage residents with dementia.
