Young woman asleep over study materials. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, [1] is a product of brain plasticity, the structural changes within synapses that create associations between stimuli.
The observed effects on memory retention the next day were similar to those obtained from people who had received no sleep. [49] Sleep deprivation may affect memory by interfering with neuroplasticity as measured by long-term potentiation in the hippocampus.
“For younger people, especially those in middle age, sleep issues (e.g., excessive daytime sleepiness, fragmented sleep patterns, undiagnosed sleep apnea) might increase the risk of future ...
Normal aging is associated with a decline in various memory abilities in many cognitive tasks; the phenomenon is known as age-related memory impairment (AMI) or age-associated memory impairment (AAMI). The ability to encode new memories of events or facts and working memory shows decline in both cross-sectional and longitudinal studies. [8]
It can impact the learning and memory processes, foster the development of auditory skills, and improve attention and memory, making it a valuable practice for overall brain health.
Given the significant impact of sleep deprivation on academic performance and the differing sleep patterns observed in students, educational institutions have begun to reconsider start times. For instance, a school in New Zealand changed its start time to 10:30 a.m. in 2006, to allow students to keep to a schedule that allowed more sleep.
Why We Sleep: The New Science of Sleep and Dreams (or simply known as Why We Sleep) is a 2017 popular science book about sleep written by Matthew Walker, an English scientist and the director of the Center for Human Sleep Science at the University of California, Berkeley, who specializes in neuroscience and psychology.
Other studies have been also looking at the specific effects of different stages of sleep on different types of memory. For example, it has been found that sleep deprivation does not significantly affect recognition of faces, but can produce a significant impairment of temporal memory (discriminating which face belonged to which set shown).
