Psychologists at the University of Sussex have found a link between depression and an premature aging, people with depression or anxiety have an increased risk of dementia in later life. Researchers conducted a robust systematic review of 34 longitudinal studies, with the focus on the link between depression or anxiety and decline in cognitive function over time.
Evidence from more than many participants was combined and reviewed. Including people who presented with symptoms of depression as well as those that were diagnosed as clinically depressed, the study looked at the rate of decline of overall cognitive state- encompassing memory loss, executive function (such as decision making) and information processing speed.
They discovered that people with depression experienced a greater decline in cognitive state in older adulthood than those without depression. As there is a long pre-clinical period of several decades before dementia may be diagnosed, the findings are important for early interventions as currently there is no cure for the disease.
Mental wellbeing can be protected by exercising, practicing mindfulness and undertaking recommended therapeutic treatments, like Cognitive Behaviour Therapy.
