Using mental visual imagery to improve autobiographical memory and episodic future thinking in relapsing-remitting...

Area of Science:

• Cognitive Neuroscience
• Clinical Psychology
• Neurorehabilitation

Background:

• Relapsing-remitting multiple sclerosis (RR-MS) patients often exhibit co-occurring impairments in autobiographical memory (AM) and episodic future thinking (EFT).
• Understanding the cognitive underpinnings and effective interventions for these memory deficits is crucial for improving patient quality of life.

Purpose of the Study:

• To investigate the efficacy of a mental visual imagery (MVI)-based facilitation program on AM and EFT functioning in RR-MS patients.
• To assess the long-term effects and potential mechanisms of the MVI intervention through a randomized-controlled trial.

Main Methods:

• A randomized-controlled trial involving 40 RR-MS patients with AM/EFT impairment.
• Participants were assigned to an MVI program, a sham verbal program (verbal control), or a no-intervention stability group.
• Autobiographical memory and episodic future thinking were assessed using the Autobiographical Interview (AI).

Main Results:

• The experimental group receiving the MVI program showed significant improvements in both AM and EFT performance.
• These improvements were robust and sustained over the long term.
• Control groups did not show significant improvements, ruling out test learning or nursing effects.

Conclusions:

• The MVI program effectively enhances AM and EFT in RR-MS patients.
• The findings suggest that MVI facilitates a common underlying cognitive process of scene construction essential for both AM and EFT.
• Patient feedback confirmed the practical application of MVI strategies in daily life, highlighting its therapeutic potential.
