Effective dietary supplements to maintain cognitive functions and memory

Chapter 1: Understanding of cognitive functions and memory: Fundamentals and mechanisms

Cognitive functions cover a wide range of mental processes that allow us to interact with the outside world, study, solve problems and adapt to new situations. Memory, being a key component of cognitive activity, is responsible for storage, coding and reproduction of information. The effective functioning of the cognitive system and memory is critical of maintaining the quality of life, academic performance, professional success and general well -being.

1.1. Main cognitive functions:

• Attention: The ability to concentrate on certain incentives, ignoring distracting factors. Attention is selective, stable, divided and switched. Violations of attention are manifested in the form of absent -mindedness, impulsiveness and difficulties with concentration.

• Memory: The process of coding, storage and extraction of information. The memory is divided into sensory, short -term (working) and long -term. Long -term memory includes declarative (episodic and semantic) and procedural memory. Forgetting, distortion of memories and amnesia are examples of memory disorders.

• Executive functions: Complex cognitive processes necessary for planning, organization, decision -making, solving problems and adaptation to new situations. Executive functions include working memory, cognitive flexibility and pulse control. Violations of executive functions are manifested in the form of difficulties with planning, organization, adaptation to changes and behavior control.

• Language: The ability to understand and use oral and written speech. The language includes phonetics, morphology, syntax, semantics and pragmatics. Afasia, dyslexia and dysgraphia are examples of linguistic disorders.

• Visual-spatial functions: The ability to perceive, analyze and manipulate visual information. Visual and spatial functions include orientation in space, visual memory, recognition of objects and perception of depth. Violations of visual-spatial functions are manifested in the form of difficulties with orientation in space, person recognition and copying of drawings.

1.2. Memory mechanisms:

Memory is a complex multi -stage process that includes several stages:

• Coding: Convert information into a format that can be saved in the brain. Coding can be sensory (based on sensations), acoustic (based on sounds) or semantic (based on meaning).

• Storage: Holding encoded information in the brain for a certain period of time. Storage can be short -term or long -term. Short -term memory has a limited capacity and duration, while long -term memory has almost unlimited capacity and duration.

• Extraction: Restoring saved information from the brain. Extraction can be arbitrary (conscious and purposeful) or involuntary (automatic and unconscious).

At the molecular level, memory is associated with changes in synaptic connections between neurons. Long -term potential (LTP) and long -term depression (LTD) are two main mechanisms underlying synaptic plasticity, which is the basis for the formation and storage of memories.

1.3. Factors affecting cognitive functions and memory:

Many factors affect cognitive functions and memory, including:

• Age: With age, a natural decrease in cognitive functions occurs, including memory, attention and speed of information processing.

• Genetics: A genetic predisposition plays a certain role in cognitive abilities and the risk of developing neurodegenerative diseases, such as Alzheimer’s disease.

• Life: A healthy lifestyle, which includes proper nutrition, regular physical exercises, sufficient sleep and rejection of bad habits, helps maintain cognitive health.

• Nutrition: Certain nutrients, such as omega-3 fatty acids, vitamins of group B and antioxidants, are important for brain health and cognitive functions.

• Stress: Chronic stress can negatively affect cognitive functions and memory.

• Diseases: Some diseases, such as depression, anxiety disorders, stroke and Alzheimer’s disease, can lead to a decrease in cognitive functions.

1.4. Diagnosis of cognitive disorders:

Diagnosis of cognitive disorders includes a history of anamnesis, a neurological examination and neuropsychological testing. Neuropsychological testing allows you to evaluate various cognitive functions, such as memory, attention, executive functions, language and visual-spatial skills. The results of neuropsychological testing help to determine the degree and nature of cognitive disorders, as well as to identify their possible causes.

Chapter 2: The role of dietary supplements in maintaining cognitive functions and memory: Scientific review

Biologically active additives (dietary supplements) are increasingly considered as a potential means for maintaining cognitive functions and memory. However, it is important to understand that dietary supplements are not medicines and are not intended for the treatment of diseases. Their role is to supplement the diet and maintain general health, including brain health. The effectiveness of dietary supplements to improve cognitive functions varies and depends on the specific substance, dosage, duration of administration, individual characteristics of the body and the presence of other factors affecting cognitive health. It is important to critically evaluate scientific data and consult a doctor before taking any dietary supplements.

2.1. Criteria for choosing dietary supplements for cognitive support:

When choosing dietary supplements to maintain cognitive functions and memory, the following factors must be taken into account:

• Scientific validity: Choose dietary supplements, the effectiveness of which is confirmed by scientific research published in reviewed magazines. Pay attention to meta analyzes and systematic reviews that combine the results of several studies.

2.2. The main groups of dietary supplements to maintain cognitive functions:

Bades that are potentially capable of maintaining cognitive functions can be divided into several groups:

• Omega-3 fatty acids: EPA (eicosapentaenic acid) and DHA (non -coshegexic acid) are essential fatty acids necessary for the health of the brain. They are part of the cell membranes of neurons and play an important role in the transmission of nerve impulses, neurogenesis and protection from neurodegenerative processes.

• B vitamins B: Vitamins B1 (thiamine), B6 ​​(pyridoxin), B9 (folic acid) and B12 (cobalamin) are necessary for the normal functioning of the nervous system. They participate in glucose metabolism, the synthesis of neurotransmitters and maintaining the myelin shell of nerve fibers.

• Antioxidants: Vitamin C, vitamin E, selenium, coenzyme Q10 and polyphenols protect brain cells from damage by free radicals, which are formed during metabolism and can lead to oxidative stress.

• Nootropics: Piracetam, choline, DMAE (dimethylaminoetanol) and Bakop Monyunia stimulate cognitive functions, improve memory, attention and learning. Their mechanisms are different and include an improvement in blood circulation of the brain, increased neurotransmission and protect neurons from damage.

• Plant extracts: Ginkgo biloba, ginseng, rhodiola pink and green tea contain biologically active substances that can improve cognitive functions, reduce fatigue and increase stress resistance.

2.3. A detailed review of the most investigated dietary supplements:

• Omega-3 fatty acids (EPA and DHA):

  • The mechanism of action: DHA is the main structural component of membranes of neurons and synaps, which ensures their flexibility and normal functioning. EPA has an anti-inflammatory effect and can reduce the level of beta amyloid, which accumulates in the brain during Alzheimer’s disease.
  • Scientific evidence: Numerous studies show that the use of omega-3 fatty acids is associated with the improvement of cognitive functions, especially in the elderly. Some studies also indicate that omega-3 fatty acids can reduce the risk of developing dementia and Alzheimer’s disease.
  • Recommendations for use: The recommended daily dose of DHA is 250-500 mg. EPA is also important, but its dosage can vary depending on individual needs. It is best to receive omega-3 fatty acids from food, such as fatty fish (salmon, tuna, herring), linen seed and walnuts. As an additive, you can use fish oil or croil oil.
  • Side effects: In high doses of omega-3, fatty acids can cause stomach disorder, nausea and diarrhea. They can also increase the risk of bleeding, so they should be used with caution to people taking anticoagulants.

• B vitamins B (B1, B6, B9, B12):

  • The mechanism of action: B vitamins are involved in the metabolism of homocysteine, the high level of which is associated with an increased risk of developing cognitive impairment. They are also necessary for the synthesis of neurotransmitters, such as serotonin, dopamine and norepinephrine, which play an important role in regulating mood, attention and memory.
  • Scientific evidence: Studies show that the deficiency of B vitamins can lead to cognitive impairment, depression and dementia. Reception of B vitamins can improve cognitive functions in people with a deficiency of these vitamins.
  • Recommendations for use: The recommended daily dose of B vitamins varies depending on age and health. It is best to get group B vitamins from food, such as meat, fish, eggs, dairy products, legumes and green leafy vegetables. As an additive, you can use a complex of B vitamins B.
  • Side effects: In high doses, group B vitamins can cause side effects, such as nausea, diarrhea, skin rash and nervous disorders.

• Ginkgo biloba:

  • The mechanism of action: Ginkgo bilobe improves blood circulation of the brain, protects neurons from damage by free radicals and improves the transmission of nerve impulses.
  • Scientific evidence: Some studies show that ginkgo bilobe can improve memory and attention in people with cognitive disorders, especially with Alzheimer’s disease. However, research results are contradictory.
  • Recommendations for use: The recommended dose of ginkgo biloba is 120-240 mg per day. The drug should be taken for several months to evaluate its effectiveness.
  • Side effects: Ginkgo bilobe can cause headache, dizziness, stomach disorder and allergic reactions. It can also increase the risk of bleeding, so it should be used with caution to people taking anticoagulants.

• Bacopa Monnieri:

  • The mechanism of action: Bakop Monier contains bacosides that improve cognitive functions, memory and learning. They protect neurons from damage to free radicals and improve the transmission of nerve impulses.
