Good sleep quality and good mood lead to good working memory with age

Posted on June 22, 2019

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 one of the most important cognitive functions responsible for one’s intelligence, creative problem-solving, language, and action-planning. It plays a big role in how we process, use and remember information.

While all three factors contribute to a common complaint about foggy memory, the factors contribute to the working memory in different ways and may thus result in potentially independent mechanisms in our brain.

Two studies were conducted; in the first study – researchers sampled 110 college students for self-reported measures of sleep quality and depressed mood and their independent relationship to experiment measures of the working memory. In the second study, researchers sampled 31 members of the community from 21 – 77 years old. In this study, researchers investigated the age and its relationship to our working memory.

These findings could lead to future interventions and treatments to counteract the negative impacts of these factors on working memory. The new research will provide a better understanding of the underlying mechanism in age-related dementia. For the mind to work at its best, it is essential that senior citizens have a good sleep quality and be in a good mood.
