Adelaide University study links cognitive reserve to trauma resilience
Staying connected and enjoying meaningful activities may help protect brain health as we get older, according to Australian research exploring why some people remain more resilient after traumatic life experiences.
- An Adelaide University study tracked 745 adults aged 50 to 86 to examine trauma, post-traumatic stress symptoms, and cognitive performance.
- Researchers found that higher cognitive reserve was associated with weaker links between trauma, post-traumatic stress symptoms, and poorer cognitive performance.
- Published in the Journal of Affective Disorders, the findings suggest leisure and social activities support cognitive reserve, offering protection against adversity in later life.
Adelaide University Study on 745 Adults Aged 50 to 86
The Adelaide University study examined the links between trauma, post-traumatic stress symptoms, and cognitive performance among 745 participants. About 87 percent of participants reported directly experiencing at least one traumatic event. Despite this high prevalence of adversity, researchers noted that experiencing trauma does not necessarily mean an individual will develop cognitive difficulties later in life.
Cognitive Reserve as a Buffer Against Trauma
Cognitive reserve describes the brain’s capacity to adapt and cope with changes associated with ageing, thought to develop through enriching experiences across life, including education and leisure activities. Dr Sabrina Sghirripa explained that while discussions about healthy brain ageing often focus on staying active and socially engaged, understanding the influence of difficult life experiences remains essential. To measure these factors, individuals took part in evaluations addressing traumatic event exposure, post-traumatic stress symptoms, cognitive function, and cognitive reserve indicators.
Associations Between Adversity and Cognitive Resilience
The data revealed that greater cognitive reserve lessened the connection connecting traumatic events, post-traumatic stress symptoms, and reduced cognitive functioning. The findings point to cognitive reserve as a possible source of resilience. However, the study identified associations rather than proving that particular activities prevent trauma-related cognitive difficulties.
Future Implications for Social Engagement and Brain Ageing
Dr Sghirripa noted that leisure activities and social engagement could offer opportunities to support cognitive reserve in later life. For people who have experienced adversity, the research offers an encouraging message that difficult experiences do not inevitably lead to poorer wellbeing as they get older.
