Study Shows, Memory Loss in Old Age is Not Triggered by Sexual Intimacy

Getting naughty under the sheets as well as remaining emotionally attached to romantic partners in old age may not be linked to decline in memory skills, finds a study.

Getting naughty under the sheets as well as remaining emotionally attached to romantic partners in old age may not be linked to declining in memory skills, finds a study.

Although lifestyle factors, level of education, smoking and drinking habits and physical activity all play a role in the rate and extent of the age-related cognitive decline, the study now shows that there is no link between sexual activity and rate of cognitive decline.

“Decline in memory performance over time was unrelated to sexual activity or emotional closeness during partnered sexual activity,” said Mark Allen of the University of Wollongong in Australia.

For the study, published in the journal Archives of Sexual Behavior, the team used data from more than 6,000 adults aged 50 and over.

Participants 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.

Further, the study builds on previous experimental work that showed sexual activity enhances elderly rodents’ ability to recognize objects and, therefore, ultimately their episodic memory workings and overall brain health.

Memory slips with age, but getting a fair amount of sleep every night and having a cheerful mood each day may help you stay sharp even when you grow old, suggests new research.

Poor sleep quality and a depressed mood are linked to a reduced likelihood of remembering a previously experienced event, said the study published in the Journal of the International Neuropsychological Society.

The researchers found strong associations between working memory and three health-related factors such as sleep, age and depressed mood.

Working memory is the part of short-term memory that temporarily stores and manages information required for cognitive tasks such as learning, reasoning and comprehension.

Working memory is critically involved in many higher cognitive functions, including intelligence, creative problem-solving, language and action-planning. It plays a major role in how we process, use and remember information.

The study found that age is negatively related to the “qualitative” aspect of working memory — that is, how strong or how accurate the memory is.

“Other researchers have already linked each of these factors separately to overall working memory function, but our work looked at how these factors are associated with memory quality and quantity – the first time this has been done,” said Weiwei Zhang, Assistant Professor at the University of California, Riverside in the US.

“All three factors are interrelated. For example, seniors are more likely to experience negative mood than younger adults. Poor sleep quality is also often associated with depressed mood”, Zhang added.

The researchers performed two studies. In the first study, they sampled 110 college students for self-reported measures of sleep quality and depressed mood and their independent relationship to experimental measures of working memory.

In the second study, the researchers sampled 31 members of a community ranging in age from 21 to 77 years. In this study, the researchers investigated age and its relationship to working memory.

The researchers are the first to statistically isolate the effects of the three factors on working memory quantity and quality.

Although all three factors contribute to a common complaint about foggy memory, they seem to behave in different ways and may result from potentially independent mechanisms in the brain.

These findings could lead to future interventions and treatments to counteract the negative impacts of these factors on working memory. (IANS)
