Nootropics (/ n oʊ. ə ˈ t r oʊ p ɪ k s / noh-ə-TROHP-iks or / n oʊ. ə ˈ t r ɒ p ɪ k s / noh-ə-TROP-iks), [1] colloquially brain supplements, smart drugs and cognitive enhancers, are natural, semisynthetic or synthetic compounds which purportedly improve cognitive functions, such as executive functions, attention or memory.
The hippocampus regulates memory function. Memory improvement is the act of enhancing one's memory. Factors motivating research on improving memory include conditions such as amnesia, age-related memory loss, people’s desire to enhance their memory, and the search to determine factors that impact memory and cognition.
Of the study participants, women were at a higher risk of developing dementia than men, but they also had a better response to the vitamin D intervention—women who took it had a 49% lower risk ...
These two brain structures are responsible for motor functions and linking the nervous system to the endocrine system, respectively. The expression of these metabolite derivatives in these areas suggests that these structures have the ability to synthesize these products from vitamin D. [1] Location of brain regions related to vitamin D
Brain training (also called cognitive training) is a program of regular activities purported to maintain or improve one's cognitive abilities. The phrase “cognitive ability” usually refers to components of fluid intelligence such as executive function and working memory .
Poor diet in early childhood affects the number of neurons in parts of the brain. [1]Nutritional neuroscience (neuronutrition) is the scientific discipline that studies the effects various components of the diet such as minerals, vitamins, protein, carbohydrates, fats, dietary supplements, synthetic hormones, and food additives have on neurochemistry, neurobiology, behavior, and cognition.
One study showed that eating more protein (about 1.2 grams of protein per kilogram of body weight) can help maintain muscle mass and prevent muscle loss in older adults.
Notably, muscarinic antagonists reduce the activation of the parasympathetic nervous system. The normal function of the parasympathetic system is often summarised as "rest-and-digest", and includes slowing of the heart, an increased rate of digestion, narrowing of the airways , promotion of urination, and sexual arousal.
