By contrast, other studies have indicated that the effects of sleep deprivation on cognitive performance, specifically sustained visual attention, are more global and bilateral in nature (as opposed to more lateralized deficit explanations). In a study using the Choice Visual Perception Task, subjects were exposed to stimuli appearing in ...
This leads to a restoration in HPA activity and stress reactivity, thus restoring the deleterious effects induced by stress on 5-HT. [ 119 ] The hypothalamic-pituitary-adrenal axis is a chain of endocrine structures that are activated during the body's response to stressors of various sorts.
Each macronutrient can impact cognition through multiple mechanisms, including glucose and insulin metabolism, neurotransmitter actions, oxidative stress and inflammation, and the gut-brain axis. [4] [5] [6] Inadequate macronutrient consumption or proportion could impair optimal cognitive functioning and have long-term health implications.
In fact, many studies have found a bidirectional relationship between stress and sleep. This means that sleep quality can affect stress levels, and stress levels can affect sleep quality. Sleep change depends on the type of stressor, sleep perception, related psychiatric conditions, environmental factors, and physiological limits. [5] [6] [4] [7]
Chronotype can affect how sleep deprivation influences mood. Those with morningness (advanced sleep period or "lark") preference become more depressed after sleep deprivation, while those with eveningness (delayed sleep period or "owl") preference show an improvement in mood. [62] Mood and mental states can affect sleep as well.
In this disorder, vitamin D is believed to be involved in the development of the brain during the gestational period. Gestational vitamin D deficiency in rats is associated with reduced levels of neurotrophic factors NGF and GDNF. [7] NGF is the nerve growth factor, which is involved in neurotransmission.
Almost in all cases, sleep deprivation has detrimental effects. For example, cortisol, which is essential for metabolism (it is so important that animals can die within a week of its deficiency) and affects the ability to withstand noxious stimuli, is increased by waking and during REM sleep. [135]
Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. [11] [12] Specifically, it is a deficiency, excess, or imbalance of energy, protein and other nutrients which adversely affects the body's tissues and form.
