Middle-aged men experiencing lower levels of sexual satisfaction may be at risk of future cognitive decline, warns a new study from Penn State University. The research examined associations between erectile function, sexual satisfaction, and cognition, discovering that decreases in sexual satisfaction and erectile function were correlated with subsequent memory loss. The lack of satisfaction itself may be a warning sign of problems associated with dementia, Alzheimer’s disease, and cardiovascular disease. The study used survey data from almost 820 men over a 12-year span, using neuropsychological tests and self-reported assessments for male sexual health.
Scientists have already identified a link between microvascular changes and declines in erectile function as individuals age. The effect is well documented and was the reason for the initial development of the active ingredient in Viagra (Sildenafil), originally developed to treat cardiovascular problems. However, this study takes the research further, indicating that assessments of sexual health may identify those at risk of cognitive decline before they reach 70. The researchers call for increased analysis of the relationship between erectile function and other aspects of health to gain greater clarity on the issue.
Over the next 30 years, the number of adults in the US over the age of 60 is expected to double, making research into cognitive and sexual health not only important for a significant part of the population, but also vital for healthcare providers to offer preventative measures, rather than costly treatment. The team also stressed the need to recognise that treating erectile dysfunction should not be the only outcome, and improving sexual satisfaction could have positive benefits for overall well-being and subsequent memory function.
