The gut–memory connection is the relation between the gastrointestinal tract and memory performance. The phenomenon of the gut–memory connection is based on and part of the idea of the gut-brain axis, a complex communication network, linking the central nervous system to the gut.
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.
Mineral deficiency is a lack of the dietary minerals, the micronutrients that are needed for an organism's proper health. [1] The cause may be a poor diet , impaired uptake of the minerals that are consumed, or a dysfunction in the organism's use of the mineral after it is absorbed.
Studies have shown overlapping mechanisms in psoriasis and depression; psoriasis causing disturbances in the gut microbiota that reflect in the brain causing depression that in turn can cause the stress that affects the microbiome. [39] Probiotics may reduce symptoms of depression through the vagus nerve and sympathetic pathways.
Poor diet in early childhood affects the number of neurons in parts of the brain. [1]Nutritional neuroscience 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.
Atrophy of the hippocampus has been observed during depression, consistent with animal models of stress and neurogenesis. [116] [117] Stress can cause depression and depression-like symptoms through monoaminergic changes in several key brain regions as well as suppression in hippocampal neurogenesis. [118]
Numerous cohort studies have shown associations between disorders of mineral metabolism and fractures, cardiovascular disease, and mortality. [2] These observational studies have broadened the focus of CKD-related mineral and bone disorders (MBDs) to include cardiovascular disease (which is the leading cause of death in patients at all stages ...
If this happens, vitamin B 12 deficiency may result in sense loss, loss of sensation in the feet, difficulty walking, poor balance, blurred vision, changes in reflexes, muscle weakness, decreased smell and taste, decreased level of consciousness, mood changes, memory loss, depression, irritability, anxiety, clumsiness, disorientation, psychosis ...
