The Dangerous Combination Impacting Brain Health
Joint pain and depression in older adults may not only affect physical well-being but could also accelerate cognitive decline, according to a study involving nearly 5,000 older individuals in the UK over a 12-year period. Those experiencing both chronic joint pain and depression showed greater deterioration in cognitive function, particularly in memory, compared to individuals with only one of these conditions.
Patrícia Silva Tofani, a gerontology researcher from Brazil and the study’s lead author, explained that both chronic pain and depression impact the brain areas associated with cognitive processes, especially the hippocampus. She theorizes that the combined effect of pain and depression creates a cognitive overload, causing the brain to struggle with processing both the pain signals and emotional distress. This “congestion” of brain functions could impair memory formation and overall cognitive abilities, leading to quicker cognitive decline over time.
The study, published in Aging & Mental Health, drew on data from the English Longitudinal Study of Aging, tracking 4,718 individuals aged 50 and older. Participants were assessed for chronic joint pain, depression levels, and cognitive performance over the course of the study. Cognitive functions were examined across six areas: executive function, language, attention, memory, perceptomotor skills, and social cognition.
The results showed that individuals who had both joint pain and depression experienced a significantly faster decline in memory and overall cognitive function compared to those who had only one of the conditions. However, the combination of pain and depression did not appear to affect executive function, which involves decision-making and planning.
Study co-author Tiago da Silva Alexandre, a gerontology professor, noted that the findings were unexpected, as the team had not anticipated such a pronounced cognitive decline in the group with both conditions. The study emphasizes that joint pain and depression, which are commonly seen in older adults, should not be dismissed as inevitable aspects of aging. Failure to address both conditions could negatively impact mood, mobility, and cognitive health, ultimately compromising the independence of older individuals.
The researchers stress the importance of recognizing and treating both chronic pain and depression in older adults to help preserve cognitive function and maintain autonomy. According to Alexandre, professionals who downplay the symptoms of depression and pain in older patients may unintentionally overlook treatable conditions that can severely affect the individual’s quality of life.
