Topic: Risk, prevention and care in population studies
Emotion scores for fear and surprise were significantly higher for the AD group than for the MCI group during dual tasks (p=0.016), while emotion scores for joy were significantly higher for the MCI group than for the AD group during creative activities (p=0.012). Creative activities and dual tasks, which require simultaneous physical activity and cognitive thinking, were difficult for patients with AD. On the other hand, tasks which used a range of cognitive functions, such as creative activities, evoked joy in patients with MCI. It may be beneficial to provide tasks and support to patients with respect to their unique emotions based on these results.
Key findings
- Emotion scores for fear and surprise were significantly higher for the AD group than for the MCI group during dual tasks (p=0.016), while emotion scores for joy were significantly higher for the MCI group than for the AD group during creative activities (p=0.012).
- Creative activities and dual tasks, which require simultaneous physical activity and cognitive thinking, were difficult for patients with AD.
- On the other hand, tasks which used a range of cognitive functions, such as creative activities, evoked joy in patients with MCI.
- It may be beneficial to provide tasks and support to patients with respect to their unique emotions based on these results.
Why it matters
This study looked at emotions during rehabilitation activities in people with mild cognitive impairment and Alzheimer's dementia, and it did not test any treatment, cure or prevention. It suggests that activities and support could be tailored to patients' emotions, but it provides no evidence about changing the disease itself.
