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 ...
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.
Further, nutritional deficiencies in magnesium, [2] vitamin D, [3] and tryptophan have been linked with depression; these deficiencies may be caused by the individual's environment, but they have a biological impact.
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.
DSPD patients with depression may be best served by seeking treatment for both problems. There is some evidence that effectively treating DSPD can improve the patient's mood and make antidepressants more effective. [13] Vitamin D deficiency has been linked to depression. [14]
Known as slow-wave sleep or stage 3 non-REM sleep, this is the deepest stage of sleep and the hardest to wake up from. Brain activity slows down, muscles and bones strengthen, hormones regulate ...
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.
However, it is clear that stress and sleep in college students are interrelated, instead of one only affecting the other. "Stress and sleep affect each other. Poor sleep can increase stress, otherwise high-stress can also cause sleep disturbances". [8] As stated in a different way, the way stress and sleep are related is bidirectional in nature ...
