One early study into neurochemical influences on sleep and memory was conducted with cats and demonstrated that sleep deprivation increased brain protein synthesis. There is evidence that these altered levels of proteins could increase the excitability of the central nervous system, thus increasing the susceptibility of the brain to other ...

Sleep quality issues in early middle-age are associated with accelerated brain aging and cognitive problems later in life, according to new research. Sleep problems in 30s and 40s may add extra ...

Issues in memory can also be linked to several common physical and psychological causes, such as: anxiety, dehydration, depression, infections, medication side effects, poor nutrition, vitamin B12 ...
The specific causal relationships between sleep loss and effects on psychiatric disorders have been most extensively studied in patients with mood disorders. [ 149 ] [ medical citation needed ] Shifts into mania in bipolar patients are often preceded by periods of insomnia , [ 150 ] and sleep deprivation has been shown to induce a manic state ...
Slow-wave sleep is considered important for memory consolidation. [8] This is sometimes referred to as "sleep-dependent memory processing". [9] Impaired memory consolidation has been seen in individuals with primary insomnia, who thus do not perform as well as those who are healthy in memory tasks following a period of sleep.
