Effects of chronic low back pain on cognitive functions in older adults

The Impacts of Chronic Non-specific Low Back Pain on Cognitive Functions of Older Adults: a Cross-sectional Study

Observational The Hong Kong Polytechnic University · NCT06704425

This study looks at how chronic low back pain affects thinking skills in older adults aged 60 to 85 to see if pain impacts their memory and ability to manage daily tasks.

What this trial studies

This observational study investigates the relationship between chronic non-specific low back pain (CNSLBP) and cognitive functions in older adults aged 60 to 85. It aims to explore how chronic pain may impact executive functions such as inhibition, switching, and working memory, which are crucial for managing pain and daily activities. Participants will include both those with and without CNSLBP, and cognitive performance will be assessed using the Hong Kong Montreal Cognitive Assessment. The study will utilize brain imaging to examine potential correlations between chronic pain and cognitive decline.

Who should consider this trial

Good fit: Ideal candidates are older adults aged 60 to 85, right-handed, Cantonese-speaking, with normal cognitive function and a minimum of 6 years of formal education.

Not a fit: Patients with specific causes of low back pain or those with neurological or psychiatric disorders may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of how chronic pain affects cognitive functions, leading to better management strategies for older adults.

How similar studies have performed: Preliminary evidence from other studies suggests a correlation between chronic pain and cognitive decline, indicating that this approach has some support in existing literature.
