Age-related cognitive decline varies considerably and can range from mild to severe - in the case of people living with dementia. Lifestyle factors, such as someone's level of education, smoking and drinking habits, and level of physical activity have all been found to play a role in the rate and extent of age-related cognitive decline. This study now shows that there is no link between sexual activity and rate of cognitive decline.
Allen investigated whether ongoing sexual activity and the experience of emotional closeness with a partner has any effect on memory. He analyzed and compared data from 2012 and 2014 contained in the English Longitudinal Study of Aging (ELSA), which includes information about the health, diet, well-being and socio-economic status of adults older than 50 living in England. Participants in the ELSA completed an episodic memory task and a questionnaire where they reported the frequency of intimate activities such as kissing, sexual touching and intercourse.
Allen found an overall decline in all participants' score on the memory test over time.
"Decline in memory performance over time was unrelated to sexual activity or emotional closeness during partnered sexual activity" says Allen.
