Regional brain energy substrate hypometabolism in mild AD dementia may be specific to impaired glucose uptake and/or utilization. This suggests a potential avenue for compensating brain energy deficit in AD dementia with ketones.
Alzheimer's disease is a degenerative disease characterised by a progressive loss of cognitive functions and impairment of activities of daily living severe enough to interfere with normal functioning. To help persons with this disease perform a variety of activities, our research team developed AP@LZ, an electronic organiser specifically designed for them. Two participants with Alzheimer's disease learned how to use AP@LZ in their daily lives by following a structured learning method. After the learning phase, the participants were able to use AP@LZ efficiently and facilitate their day-to-day activities for several months, despite the steady progression of the disease. These results suggest that persons with Alzheimer's disease can learn to use new technologies to compensate for their everyday memory problems, which opens up new rehabilitation possibilities in dementia care.
New technologies, such as tablet computers, present great potential to support the day-to-day living of persons with Alzheimer's disease (AD). However, whether people with AD can learn how to use a tablet properly in daily life remains to be demonstrated. A single case study was conducted with a 65-year-old woman with AD. A specific and structured intervention tailored to her needs was conceptualised for the use of a calendar application on a tablet computer according to the following learning stages: Acquisition, Application and Adaptation. In spite of her severe episodic memory deficit, she showed progressive learning of the tablet application during the intervention phase. Furthermore, data compiled over 12 months post-use show that she used the tablet successfully in her day-to-day life. She was even able to transfer her newly acquired ability to other available applications designed to monitor regular purchases, consult various recipes and play games. Tablet computers thereby offer a promising avenue for cognitive rehabilitation for persons with AD. This success was mainly achieved through a one-on-one individual programme tailored to this person. The limits and constraints of utilising tablet computers for persons with AD are discussed.
In mild AD, aerobic training improved brain energy metabolism by increasing ketone uptake and utilization while maintaining brain glucose uptake, and could potentially be associated with some cognitive improvement.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
