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 ...
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.
One of the important questions in sleep research is clearly defining the sleep state. This problem arises because sleep was traditionally defined as a state of consciousness and not as a physiological state, [14] [15] thus there was no clear definition of what minimum set of events constitute sleep and distinguish it from other states of partial or no consciousness.
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 ...
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 ...
Memory lapses can be both aggravating and frustrating but they are due to the overwhelming number of information that is being taken in by the brain. 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 ...
People may wish to take naps during the day, but unintentionally getting too much sleep will affect nighttime sleep. Physical activity is a treatment for Alzheimer's and a way to encourage night sleep. [5] Caffeine is a (fast-working) brain stimulant, but should be limited at night if a night's sleep is needed.

The book is written from a neuroscientific view, mainly devoted to discussing the impact of sleep on the functions of the human brain. It is divided into four parts, focusing on how sleep works, its benefits, the reason for dreams and sleep issues surrounding society. [2] The book is written so that it does not need to be read sequentially.
