Consequently, they are dependent on their caregivers or use pen-and-paper organizers, both of which have limitations. A more interesting alternative could be an electronic organizer that optimizes the functional autonomy of persons with AD. This article describes the development of an electronic organizer called AP@LZ by an interdisciplinary team of computer specialists and clinicians. The results show how knowledge of technology and knowledge of the cognitive capacities of persons with AD can be combined. A pre-experimental phase confirmed that AP@LZ was easy to use by elderly participants.

Evidence of this inter-individual variability has had an important impact on the approaches to the cognitive rehabilitation of AD, particularly in the early stages of the disease. Research has shown that, despite variable cognitive profiles, many preserved capabilities are observed in the first stages of AD and that the disease does not affect all cognitive functions globally. These preserved capabilities make it possible to apply cognitive interventions. However, numerous methodological difficulties are encountered in evaluating the effectiveness of these interventions, many of which are related to the heterogeneity of the deficits. The purpose of this article is to discuss this heterogeneity and its impact on methodological characteristics, especially participant selection and research design.

The first participant, DD, learned to look at a calendar with the spaced retrieval method to answer his repeated questions about the current date and calls made to family. Progressive cuing was used by his wife to increase spontaneous use of the calendar, but DD had difficulty integrating the calendar into his routine. The second patient, MD, relearned a leisure activity (listening to music on a cassette radio) and how to participate in a social activity (saying the rosary in a group) with a combination of learning methods. Transfer of these skills in similar contexts was difficult for MD. She never integrated the cassette radio into her daily life routine but she went regularly to the rosary activity, which was cued by an alarm clock. In sum, the learning methods used were very effectiv...

The present study aimed to establish normative data for this test in the elderly French-Quebec population. A total of 432 French-speaking elders from the province of Quebec (Canada), aged 50 to 85 years, were administered the Dementia Rating Scale-2. Age and education were found to be associated with the total score on the test, while gender was not. Percentile ranks were then calculated for age- and education-stratified groups. Previous studies have shown that cultural background can affect performance on the DRS and the development of culture-specific norms for French-speaking Quebecers could be very useful to clinicians and researchers working with this population.

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.

Spared emotional judgments of music have been observed in early AD (Gagnon, Peretz, & Fülöp, 2009). The AD case study of Cuddy and Duffin (2005) showed relatively spared perception and memory for music. Through the single case study of MD, we again address the question of whether early AD might leave these abilities intact. The first experiment examined her musical emotional judgments in relation to mode and tempo. Overall results replicated the finding of a preserved response to changes in these structural properties. In a second experiment, we examined MD's recognition of musical and facial emotional expressions. She demonstrated a deficit only for the recognition of the facial expression of anger. Her performance adds to other empirical demonstrations that in early AD music perception and memory, as well as musical emotional judgments, may be relatively preserved.
