Sleep, mood and memory

Working memory is the short-term memory we use to remember a phone number or add items to a shopping list. As people get older this goes downhill but other things can effect it, including how much sleep one gets and one’s mood. Researchers from the University of California, the University of Michigan and the National Institute of Neurological Disorders and Stroke have been looking into these issues. They found that sleep, mood and age were inter-related with older people being more likely to be depressed than younger ones and poor sleep quality being more likely in depressed people. The researchers carried out two studies; one of 110 college students and one of 31 people aged between 21 and 77. The two studies found that the older people were the less accurate their working memory was and also that experiencing depressed moods and poor sleep quality was linked to worse working memory.
