Sleep deprivation may additionally affect memory by reducing the proliferation of cells in the hippocampus. [51] Sleep deprivation has also been associated with decreased overall membrane excitability of neurons in the brain. Activation of these membranes is critical for the formation of memories. [52]
Sleep deprivation, whether total or not, can induce significant anxiety, and longer sleep deprivations tend to result in an increased level of anxiety. [61] Sleep deprivation has also shown some positive effects on mood and can be used to treat depression. [10] Chronotype can affect how sleep deprivation influences mood.
Middle-age and older people should sleep seven hours each night for ideal rest and recovery, according to a study published last week. The research, published in Nature Aging, studied nearly ...
Sleep is also important for brain health, as poor sleep is a risk factor for cognitive issues such as memory loss. “Depriving humans of sleep leads to all sorts of problems and can cause serious ...
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.

[citation needed] There is a positive correlation between early life education and memory gains in older age. This effect is especially significant in women. [16] In particular, associative learning, which is another type of episodic memory, is vulnerable to the effects of aging, and this has been demonstrated across various study paradigms. [17]
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).
