Collaborative memory intervention in dementia: caregiver participation matters

Area of Science:

• Gerontology
• Neuroscience
• Psychology

Background:

• Dementia significantly impacts memory and daily functioning.
• Spousal caregivers often face challenges supporting individuals with dementia.
• Cognitive interventions aim to improve memory and quality of life.

Purpose of the Study:

• To evaluate a collaborative memory intervention for persons with dementia and spousal caregivers.
• To compare collaborative intervention with individual training and a no-training control group.
• To assess the impact on shared recall, individual memory, and caregiver well-being.

Main Methods:

• Couples learned memory strategies (spaced-retrieval, hierarchical cuing) for face-name association and task performance.
• Intervention groups included collaborative training, individual training for the person with dementia, and a control group.
• Pre- and post-test assessments measured collaborative recall and individual episodic memory.

Main Results:

• Collaborative intervention led to more equitable recall between spouses, with improved performance in persons with dementia.
• Caregivers in the collaborative group showed decreased recall, while persons with dementia showed increased recall.
• Persons with dementia in the collaborative group demonstrated greater improvement in episodic memory compared to other groups.
• No significant effects were observed on caregiver-reported episodic memory, burden, or depressive symptoms.

Conclusions:

• Active caregiver participation is crucial for effective cognitive rehabilitation in dementia.
• Collaborative memory interventions enhance shared remembering and individual memory performance in persons with dementia.
• Future research should explore caregiver-specific outcomes and long-term effects.
