How vitamins affect memory and training

Chapter 1: fundamental mechanisms of memory and learning: the basic view of neurochemistry and the plasticity of the brain

Memory and training are fundamental cognitive processes that underlie our ability to adapt, develop and interact with the outside world. Understanding their neurobiological foundations is critical of realizing the role of vitamins in the optimization of these functions.

1.1. Memorial organization of memory:

Memory is not a single entity, but a complex system, including various types and levels of storage of information. Key memory types include:

• Sensory memory: Short -term retention of sensory information (visual, auditory, tactile) for a split second.
• Short -term (working) memory: Temporary storage and manipulation of information required to complete current tasks (for example, memorizing a phone number before a set). The capacity is limited (about 7 elements).
• Long -term memory: Long -term storage of information divided into:
  • Declarative (obvious) memory: Conscious recalling of facts and events.
    • Episodic memory: The memory of personal experiences and events (for example, the memory of yesterday’s dinner).
    • Semantic memory: The memory of general knowledge and facts (for example, knowledge of the capital of France).
  • Non -coolate (implicit) memory: A memory manifested in skills and habits that does not require conscious recall.
    • Procedure memory: The memory of motor and cognitive skills (for example, cycling, playing the piano).
    • Price: The subconscious influence of previous experience on subsequent reactions.
    • Classic determination: Associative training (for example, the reaction of salivation to the sound of a bell associated with food).

1.2. Key areas of the brain participating in the processes of memory and training:

Various types of memory are associated with the activity of various areas of the brain:

• Hippocampus: Critically important for the formation of new declarative memories (episodic and semantic). Participates in the consolidation of memory, that is, in the process of transferring information from short -term memory to long -term.
• Almond -shaped body (amygdala): He processes emotional information and plays a role in the formation of emotional memories, especially related to fear and pleasure.
• Prefrontal bark: Participates in working memory, planning, decision -making and other executive functions. He plays a role in extracting information from long -term memory and manipulating it.
• Cerebellum: It is important for procedural memory, coordination of movements and teaching motor skills.
• Basal ganglia: Participate in the formation of habits and automatic behavioral reactions.
• Brain cortex (neocortex): It stores long -term declarative memories distributed by various sensory and associative areas.

1.3. Neurochemical foundations of memory and training:

The transmission of information between neurons is carried out through chemicals called neurotransmitters. Key neurotransmitters participating in the processes of memory and training include:

• Acetylcholine: It is important for attention, learning and memory. Neurons using acetylcholine are especially active in the hippocampus.
• Glutamate: The main exciting neurotransmitter in the brain. He plays a critical role in synaptic plasticity (see below).
• Gamk (gamma-aminobral acid): The main brake neurotransmitter in the brain. Regulates the excitability of neurons and is involved in the processes of memory consolidation.
• Dofamine: It is important for motivation, reward and training. He plays a role in strengthening synaptic connections associated with pleasant experience.
• Serotonin: Participates in the regulation of mood, sleep and appetite. It can affect cognitive functions, including memory and training.
• Norepinephrine: It is important for attention, vigilance and reactions to stress. It can improve memory consolidation in situations associated with emotional excitement.

1.4. Sinaptic plasticity: molecular basis of training and memory:

Sinaptic plasticity is the ability of synapses (compounds between neurons) to change its strength over time. It is believed that this is the main mechanism underlying training and memory. Two main types of synaptic plasticity:

• Long -term potential (LTP): Strengthening synaptic transmission after high -frequency stimulation. It is believed that LTP is a cellular basis for the formation of long -term memories. LTP is especially important in the hippocampus.
• Long -term depression (LTD): Weakening of synaptic transmission after low -frequency stimulation. LTD can be important for “forgetting” unnecessary information and for the fine tuning of synaptic connections.

The molecular mechanisms of the LTP and LTD include changes in the amount and functionality of neurotransmitters receptors on the postsynaptic membrane, as well as changes in the structure and function of the synapse.

1.5. Neurogenesis:

Neurogenesis is the process of the formation of new neurons in the brain. It was previously believed that neurogenesis occurs only at an early age, but now it is known that it continues in the adult brain, although in a limited number of regions, mainly in the hippocampus. Neurogenesis in Hippocampus can play a role in the formation of new memories and maintaining cognitive functions.

Chapter 2: B vitamins B: a complex effect on the energy metabolism of the brain and neuro -transmission

B vitamins are a group of water -soluble vitamins that play a vital role in energy metabolism and the functioning of the nervous system, including the brain. The lack of B vitamins can negatively affect cognitive functions, including memory and training.

2.1. Tiamin (B1): Energy engine for nerve cells:

Tiamine is a coherent necessary for carbohydrate metabolism, which are the main source of energy for the brain. Tiamin is involved in key enzymatic reactions, such as:

• Carboxylation of alpha coat acids: It is necessary for the production of energy in the Crebs cycle.
• Pentosophosphate path: It is important for the synthesis of nucleotides and Nadph, necessary for protection against oxidative stress.

The deficiency of thiamine can lead to a deficiency of energy in the brain, which can manifest itself in the form of cognitive disorders, such as:

• Confusion
• Memory loss
• Vernike-Korsakova syndrome: A severe neurological disorder characterized by confusion, ataxia (impaired coordination of movements) and ophthalmos (paralysis of the eye muscles). It is often found in people who abuse alcohol.

Tiamine also plays a role in the synthesis of acetylcholine, neurotransmitter, critical for memory and learning.

2.2. Riboflavin (B2): antioxidant protection and energy support:

Riboflavin is a coherent of flavideninindinucleotide (FAD) and Flavmononucleotide (FMN), which participate in many redox reactions in the body, including energy metabolism and antioxidant protection. Riboflavin is necessary for the functioning of the enzymes of the respiratory chain of mitochondria, which produce energy in the form of ATP.

Riboflavin also helps to protect the brain from oxidative stress, neutralizing free radicals. Oxidative stress can damage neurons and contribute to cognitive disorders.

Studies show that riboflavin can improve cognitive functions, especially in people with riboflavin deficiency.

2.3. NiaCin (B3): Regulation of energy exchange and neuroprotection:

Niacin is a cooferment of nicotinydenindinindinucleotide (NAD+) and nicotinindinindinindinucleotidfosphate (NADP+), which participate in many metabolic processes, including energy metabolism, DNA synthesis and antioxidant protection. Niacin is important for maintaining the health of neurons and protecting them from damage.

The disadvantage of niacin can lead to Pellagra, a disease characterized by dermatitis, diarrhea and dementia.

Niacin can also improve cognitive functions, increasing blood flow in the brain and improving the energy metabolism of neurons. Some studies show that niacin can improve memory and attention.

2.4. Pantotenic acid (B5): Coenzyme synthesis A and neurotransmitters:

Pantotenic acid is a component of Coenzyme A (COA), which plays a critical role in the metabolism of carbohydrates, fats and proteins. COA is necessary for the production of energy and for the synthesis of many important molecules, including acetylcholine.

Acetylcholine, as mentioned earlier, is a neurotransmitter, critical for memory and learning. Pantotenic acid, supporting COA synthesis, indirectly supports acetylcholine synthesis and, therefore, can improve cognitive functions.

The disadvantage of pantothenic acid is rare, but can lead to fatigue, headaches and sleep disturbances, which can negatively affect cognitive functions.

2.5. Pyridoxin (B6): Syntez neurotransmitterov e Homesteina:

Pyridoxine is a coherent of many enzymes involved in amino acid metabolism, a synthesis of neurotransmitters (such as dopamine, serotonin and game) and homocysteine ​​metabolism.

• Synthesis neurotransmitted: Pyridoxine is necessary for the synthesis of enzymes that turn amino acids into neurotransmitters. The lack of pyridoxine can lead to a decrease in the level of these neurotransmitters, which can negatively affect cognitive functions.
• Homocysteine ​​metabolism: Pyridoxine is involved in the metabolism of homocysteine, amino acids, the high level of which in the blood is associated with an increased risk of cardiovascular diseases and cognitive disorders. Pyridoxine helps to turn homocysteine ​​into other beneficial substances.

Studies show that pyridoxine can improve cognitive functions, especially in the elderly.

2.6. BIOTIN (B7): Metabolism and regulation of genes:

Biotin is a coherent of carboxylase, enzymes involved in the metabolism of carbohydrates, fats and proteins. Biotin also plays a role in the regulation of genes, affecting the expression of genes associated with metabolism and immune system.

The disadvantage of biotin is rare, but can lead to dermatitis, hair loss and neurological symptoms, such as depression and fatigue.

The effect of biotin on cognitive functions is less studied than the influence of other vitamins of group B. However, maintaining an adequate level of biotin is important for general health and well -being, which indirectly can affect cognitive functions.

2.7. Folic acid (B9): DNA synthesis, RNA and neurotransmitters:

Folic acid is a coherent of enzymes involved in DNA and RNA synthesis, as well as in amino acid metabolism and neurotransmitter synthesis. Folic acid is especially important for rapidly dividing cells, such as brain cells.

• Synthesis DNA and RNA: Folic acid is necessary for the proper synthesis of DNA and RNA, which is critical of the growth, development and functioning of brain cells.
• Synthesis neurotransmitted: Folic acid is involved in the synthesis of tetrahydrobiopterin (BH4), a cofactor necessary for the synthesis of neurotransmitters, such as dopamine, serotonin and norepinephrine.
• Homocysteine ​​metabolism: Folic acid, like pyridoxine, is involved in the metabolism of homocysteine.

The lack of folic acid is associated with an increased risk of cognitive impairment, depression and dementia. Studies show that folic acid supplements can improve cognitive functions, especially in older people with folic acid deficiency.

2.8. Cobalamin (B12): Myelination and Neuroprotection:

Cobalamin is a coherent of enzymes involved in the metabolism of fatty acids, DNA and RNA synthesis, as well as in maintaining the myelin shell of nerves.

• Myelination: Myelin is a fatty substance that surrounds the nerve fibers and ensures their insulation, accelerating the transmission of nerve impulses. Cobalamin is necessary to maintain the health of the myelin shell. Demielinization can lead to neurological problems and cognitive disorders.
• Homocysteine ​​metabolism: Cobalamin, like folic acid and pyridoxine, is involved in the metabolism of homocysteine.
• Synthesis neurotransmitted: Cobalamin can affect the synthesis of neurotransmitters.

The disadvantage of cobalamin can lead to pernicious anemia, neurological problems and cognitive disorders, such as memory loss, depression and confusion. B12 deficiency is often found in older people, in vegans and people with problems with the absorption of nutrients. Studies show that cobalamine additives can improve cognitive functions, especially in people with cobalamin deficiency.

Chapter 3: Vitamin C: antioxidant protection, neurotransmitter synthesis and neurogenesis

Vitamin C (ascorbic acid) is a powerful antioxidant that plays an important role in protecting the brain from oxidative stress. It also participates in the synthesis of neurotransmitters and can contribute to neurogenesis.

3.1. Antioxidant brain protection:

Vitamin C neutralizes free radicals, unstable molecules that can damage neurons and other brain cells. The brain is especially vulnerable to oxidative stress due to a high level of metabolism and a large amount of unsaturated fatty acids in cell membranes. Vitamin C helps to protect these structures from damage.

3.2. Synthesis neurotransmitted:

Vitamin C is a cofactor of enzymes involved in the synthesis of neurotransmitters, such as norepinephrine, dopamine and serotonin. These neurotransmitters play an important role in the regulation of mood, motivation, attention and memory.

3.3. Neurogenesis:

Studies show that vitamin C can contribute to neurogenesis in the hippocampus, the area of ​​the brain, which is critical for the formation of new memories. Vitamin C can stimulate the proliferation and differentiation of neuronal stem cells, which leads to the formation of new neurons.

3.4. Clinical research:

Studies show that vitamin C can improve cognitive functions, especially in the elderly and in people with cognitive impairment. For example, some studies have shown that vitamin C can improve the memory, attention and speed of information processing.

Chapter 4: Vitamin D: neuroprotement, neurotrophic support and immunomodulation

Vitamin D, known for its role in bone health, also plays an important role in the functioning of the brain. Vitamin D is a neurosteroid, that is, it can be synthesized in the brain and affect neurons.

4.1. Neuroprotection:

Vitamin D has neuroprotective properties, protecting neurons from damage caused by oxidative stress, inflammation and exteitotoxicity (damage to neurons due to excessive stimulation of glutamate).

4.2. Neurotrophic support:

Vitamin D supports the production of neurotrophic factors, such as nerves growth factor (NGF), which contribute to survival, growth and differentiation of neurons. NGF plays an important role in the formation of new synapses and strengthening existing ones.

4.3. Immunomodulation:

Vitamin D modulates the immune system, reducing inflammation in the brain. Chronic inflammation can damage neurons and contribute to cognitive impairment.

4.4. Vitamin D receptors in the brain:

Vitamin D (VDR) receptors were found in various areas of the brain, including hippocampus, prefrontal bark and cerebellum, which indicates that vitamin D can have a direct effect on these areas.

4.5. Clinical research:

Studies show that vitamin D deficiency is associated with an increased risk of cognitive impairment, depression and dementia. Some studies have shown that vitamin D additives can improve cognitive functions, especially in people with vitamin D. deficiency.

Chapter 5: Vitamin E: antioxidant protection and membrane stability

Vitamin E is a group of fat-soluble antioxidants, the main role of which is played by alpha-tocopherol. Vitamin E is important for protecting cell membranes from oxidative damage.

5.1. Protection of cell membranes:

Vitamin E is integrated into cell membranes and protects lipids from oxidation. The brain contains a large amount of lipids, which are especially vulnerable to oxidative damage. Vitamin E helps maintain the integrity and functionality of cell membranes of neurons.

5.2. Antioxidant Protection:

Vitamin E neutralizes free radicals and prevents chain oxidation reactions that can damage neurons and other brain cells.

5.3. Clinical research:

Some studies have shown that vitamin E can slow down the progression of cognitive impairment in people with Alzheimer’s disease. However, other studies have not confirmed these results. Additional studies are needed to determine the role of vitamin E in the prevention and treatment of cognitive impairment.

Chapter 6: Vitamin K: The role in blood coagulation and a possible effect on cognitive functions

Vitamin K is known for its role in blood coagulation, but it can also play a role in the functioning of the brain. Vitamin K is necessary for the synthesis of proteins involved in blood coagulation, as well as proteins present in the brain, such as GAS6 and protein S.

6.1. Vitamin K proteins in the brain:

GAS6 and protein S are involved in various processes in the brain, including neuroprotection, synaptic plasticity and removal of dead cells.

6.2. Clinical research:

Some studies have shown that vitamin K can improve cognitive functions, especially in the elderly. For example, one study showed that a higher level of vitamin K in the blood is associated with the best episodic memory. However, additional studies are needed to confirm these results.

Chapter 7: Practical recommendations for optimizing vitamins consumption to maintain brain health and cognitive functions

Optimization of the consumption of vitamins through a balanced nutrition and, if necessary, additives can contribute to maintaining brain health and improving cognitive functions.

7.1. Balanced nutrition:

The best way to get the necessary vitamins is a balanced diet, including a variety of products from different food groups.

• Vitamin C: Citrus fruits, berries, pepper, broccoli, spinach.
• Vitamin D: Bold fish (salmon, tuna, mackerel), egg yolks, enriched products (milk, cereals).
• Vitamin E: Vegetable oils (sunflower, olive), nuts, seeds, avocados, green leafy vegetables.
• Vitamin K: Green sheet vegetables (spinach, cabbage), broccoli, Brussels cabbage.

7.2. Supplements:

If a balanced diet does not provide a sufficient amount of vitamins, you can consider taking additives. However, before taking the additives, it is recommended to consult a doctor or nutritionist in order to determine the necessary doses and avoid possible interactions with drugs.

7.3. Factors affecting the need for vitamins:

The need for vitamins can vary depending on the age, gender, state of health, lifestyle and other factors. For example, older people may need more vitamin D and B12, and pregnant women – more folic acid.

7.4. Cautions:

Reception of too large doses of vitamins can be harmful. Some vitamins (especially fat -soluble) can accumulate in the body and cause toxicity. It is important to observe the recommended doses and avoid taking megadosis of vitamins without consulting a doctor.

7.5. Individual approach:

The optimal mode of taking vitamins depends on individual needs and health status. It is recommended to consult a doctor or nutritionist to develop an individual nutrition plan and receive additives taking into account your unique needs.

Chapter 8: Promising directions of research: the effect of vitamins on neurodegenerative diseases and age -related changes in cognitive functions

Studies of the influence of vitamins on cognitive functions continue, and many promising areas of research relate to the role of vitamins in the prevention and treatment of neurodegenerative diseases and age -related changes in cognitive functions.

8.1. Alzheimer’s disease:

Studies study the effect of vitamins of group B, vitamin C, vitamin D and vitamin E in the risk of Alzheimer’s disease and on the progression of the disease. Some studies have shown that sufficient consumption of these vitamins may be associated with a decrease in the risk of developing Alzheimer’s disease and a slowdown in cognitive decline.

8.2. Parkinson’s disease:

Studies study the effect of vitamin D and other vitamins on the risk of Parkinson’s disease and on the progression of the disease. Some studies have shown that vitamin D deficiency may be associated with an increased risk of developing Parkinson’s disease.

8.3. Age -related changes in cognitive functions:

Studies study the effect of vitamins on age -related changes in cognitive functions, such as a decrease in memory, attention and speed of information processing. Some studies have shown that additives of vitamins of group B, vitamin C and vitamin E can improve cognitive functions in the elderly.

8.4. The role of vitamins in synaptic plasticity and neurogenesis:

Future studies can be aimed at studying molecular mechanisms through which vitamins affect synaptic plasticity and neurogenesis, processes that are critical for training and memory.

8.5. Individualized approach to vitamin therapy:

Further studies are necessary for the development of individualized approaches to vitamin therapy, taking into account genetic factors, health status and other individual characteristics.

8.6. The combined effects of vitamins and other factors:

Future studies can study the combined effects of vitamins and other factors, such as physical activity, mental activity and diet, on cognitive functions.

Chapter 9: The resume of the influence of key vitamins on memory and training:
