Bad for the brain: myths and reality

Bad for the brain: myths and reality

Section 1: Anatomy and physiology of the brain — the basis for understanding

For an adequate assessment of the effectiveness and safety of biologically active additives (dietary supplements) for the brain, a fundamental understanding of the structure and functioning of this complex organ is necessary. The brain, the central processor of the nervous system, is responsible for a wide range of functions, ranging from basic physiological processes, such as breathing and heart rhythm, and ending with higher cognitive functions, such as thinking, memory, training and emotions.

• Structural components: The brain consists of several key parts, each of which performs specialized functions. These include:

  • The brain (cerebrum): The largest part of the brain, divided into two hemispheres (left and right), connected by the corpus callosum (Corpus callosum). The hemispheres are responsible for the highest cognitive functions, such as thinking, speech, memory and consciousness. The cerebral cortex (Cerebral Cortex), the outer layer of the brain, consists of a gray substance (neurons) and is responsible for the processing of information. The bark is divided into frontal, parietal, temporal and occipital shares, each of which has its own specific functions. Lobnaya shares are responsible for executive functions, planning, decision -making and impulse control. The parietal shares are responsible for processing sensory information, spatial orientation and navigation. The temporal lobes are responsible for hearing, memory and language. The occipital shares are responsible for vision.
  • Cerebellum (cerebellum): Located under the brain and is responsible for coordination of movements, balance and balance. He also plays a role in teaching motor skills and coordination of eye movements.
  • Stweol moss (Brainsm): It connects the brain to the spinal cord and controls vital functions, such as breathing, heart rhythm, arterial pressure and sleep. The barrel of the brain consists of the middle brain, bridge and an oblong brain.
  • Intermediate brain (Diencephalon): It is located between the brain and the brain stem and includes thalamus, hypothalamus, pineal gland and subthalamus. Talamus serves as a relay center for sensory information entering the cerebral cortex. The hypothalamus controls the autonomous nervous system, the endocrine system and regulates body temperature, hunger, thirst and sleep. Epifosis is produced by melatonin, a hormone that regulates the cycles of sleep and wakefulness.

• Cell components: The brain consists of two main types of cells:

  • Neurons: The main functional units of the brain responsible for the transmission of information through electrical and chemical signals. Neurons consist of the body of a cell (catfish), dendrites (processes receiving signals from other neurons) and axon (process that transmit signals to other neurons). Sinapses are compounds between neurons where signal transmission occurs.
  • Glial cells (Gliya): They do not play a direct role in the transmission of nerve impulses, but support neurons, providing them with nutrition, protection and structural support. There are several types of glial cells, including astrocytes, oligodendocytes, microlytes and ependymal cells.

• Neurotransmitter: Chemicals that transmit signals between neurons in synapses. Various neurotransmitters perform different functions and participate in various processes, such as mood, memory, training and movement. The main neurotransmitters include:

  • Acetylcholine: Participates in training, memory and muscle control.
  • Dofamine: Participates in motivation, pleasure, movement and attention.
  • Serotonin: Participates in the regulation of mood, sleep, appetite and aggression.
  • Norepinephrine: Participates in vigilance, attention, stress reaction and regulation of blood pressure.
  • Gamma-aminobral acid (GABA): The main brake neurotransmitter in the brain.
  • Glutamate: The main exciting neurotransmitter in the brain.

• Blood supply to the brain: The brain requires the constant intake of oxygen and glucose for normal functioning. Blood supply to the brain is carried out through two pairs of arteries: internal sleepy arteries and vertebral arteries. Violation of the blood supply to the brain, for example, with a stroke, can lead to irreversible brain damage and neurological disorders.

• Hematoencephalic barrier (GEB): A protective barrier that separates blood from the brain tissue. The GEB limits the penetration of many substances from the blood into the brain, protecting it from toxins and infections. However, the GEB also complicates the delivery of drugs and dietary supplements to the brain.

Understanding these main aspects of the anatomy and physiology of the brain is necessary for a critical assessment of claims about the benefits of human beads. It is necessary to take into account how a specific dietary supplement ingredient can affect the structure and function of the brain, how it can overcome the GEB and what potential side effects it can cause.

Section 2: Key ingredients for dietary supplements for the brain and scientific data

The market for the brain is saturated with products that promise to improve cognitive functions, memory, attention and mood. It is important to carefully evaluate scientific evidence confirming the effectiveness and safety of these ingredients. Many of these ingredients are widely advertised, but often scientific data on their effectiveness are limited or contradictory.

• Omega-3 fatty acids: Eicopascentenic acid (EPC) and non-coshegexic acid (DGC)-the main omega-3 fatty acids contained in fish oil and some plant sources. DGC is an important structural component of cell membranes in the brain and plays a role in the development and functioning of the brain.

  • Scientific data: Some studies show that omega-3 fatty acids can be useful for improving cognitive functions in older people with an age-related decrease in cognitive functions. However, the results of studies on the influence of omega-3 fatty acids on cognitive functions in healthy adults and children are ambiguous. Met-analyzes show that the supplements of omega-3 fatty acids can have a slight positive effect on memory and attention in older people, but do not have a significant effect on cognitive functions in healthy adults. Additional studies are needed to determine the optimal dose and duration of omega-3 fatty acids to improve cognitive functions.

• B vitamins B: Vitamins B1 (thiamine), B6 ​​(pyridoxine), B9 (folic acid) and B12 (cobalamin) play an important role in the metabolism of the brain and the functioning of the nervous system. B vitamins deficiency can lead to cognitive disorders and neurological problems.

  • Scientific data: Studies show that the additives of group B vitamins can be useful for improving cognitive functions in people with a deficiency of these vitamins. For example, vitamin B12 deficiency is often found in older people and can lead to dementia. In such cases, vitamin B12 additives can improve cognitive functions. However, studies on the influence of group B vitamins on cognitive functions in healthy people are ambiguous. Some studies show that the additives of group B vitamins can improve memory and attention in the elderly, but other studies do not find a significant effect. Met-analyzes show that folic acid supplements can reduce the risk of dementia in the elderly, but additional studies are needed to confirm these results.

• Antioxidants: Vitamin C, Vitamin E, Coenzyme Q10, glutathione and other antioxidants protect brain cells from damage by free radicals. Free radicals are unstable molecules that can damage cells and DNA, contributing to aging and the development of neurodegenerative diseases.

  • Scientific data: Studies show that antioxidants can protect brain cells from damage and improve cognitive functions in animals. However, the results of studies on the influence of antioxidants on cognitive functions in people are ambiguous. Some studies show that antioxidant supplements can improve memory and attention in older people, but other studies do not find a significant effect. Additional studies are needed to determine the optimal dose and combination of antioxidants to improve cognitive functions. It should also be noted that high doses of some antioxidants can be harmful.

• Creatine: An organic compound that plays a role in energy metabolism in brain cells. Creatine helps maintain the ATP level (adenosine triphosphate), the main source of energy for cells.

  • Scientific data: Studies show that creatine supplements can improve cognitive functions, especially in conditions of stress or lack of sleep. Creatine can improve memory, attention and speed of information processing. However, most of creatine studies were conducted on young people and athletes. Additional studies are needed to determine the efficiency and safety of creatine to improve cognitive functions in older people and people with neurodegenerative diseases.

• Caffeine: A stimulator that blocks the effect of adenosine, neurotransmitter, which causes drowsiness. Caffeine can improve vigilance, attention and mood.

  • Scientific data: Studies show that caffeine can improve cognitive functions, especially in fatigue conditions. Caffeine can improve memory, attention, reaction speed and mood. However, excessive caffeine consumption can lead to anxiety, insomnia and other side effects. It should also be noted that the effect of caffeine can vary depending on individual sensitivity.

• Ginkgo biloba: Extract from the leaves of the ginkgo biloba tree, which contains flavonoids and terpenoids. The ginkgo bilobe supposedly improves blood circulation in the brain and protects the brain cells from damage.

  • Scientific data: The results of studies on the influence of ginkgo bilobe on cognitive functions are contradictory. Some studies show that ginkgo bilobe can improve memory and attention in older people with an age -related decrease in cognitive functions or dementia. However, other studies do not detect a significant effect. Met-analyzes show that ginkgo bilobe can have a slight positive effect on cognitive functions in people with dementia, but additional studies are needed to confirm these results. Ginkgo bilobe can interact with some drugs, so before taking it, you need to consult a doctor.

• Bakopa Monyeri: The plant used in Ayurvedic medicine. Bakop Monieri allegedly improves memory, training and concentration of attention.

  • Scientific data: Some studies show that Monieri Bakop can improve memory and training in healthy people. However, most studies of Bakop Monieri were conducted on small groups of people and had a short duration. Additional studies are needed to confirm the effectiveness and safety of Bakop Monieri to improve cognitive functions.

• Phosphateidixine: Phospholipid, which is an important component of cell membranes in the brain. Phosphatidylserin allegedly improves memory, attention and cognitive functions.

  • Scientific data: Some studies show that phosphatidylserin can improve cognitive functions in older people with an age -related decrease in cognitive functions or dementia. However, other studies do not detect a significant effect. Additional studies are needed to determine the optimal dose and duration of phosphatidylserin to improve cognitive functions.

Section 3: Myths and reality about dietary supplements for the brain

A wide advertising of dietary supplements for the brain often creates unreasonable expectations and spreads myths about their effectiveness. It is important to distinguish between scientifically sound facts and advertising statements.

• Myth 1: Dietary supplement for the brain can significantly improve cognitive functions in healthy people.

  • Reality: Although some dietary supplements can have a slight positive effect on cognitive functions in certain groups of people (for example, elderly people with an age -related decrease in cognitive functions), there is no convincing evidence that dietary supplements can significantly improve cognitive functions in healthy people with a normal level of cognitive abilities. In most cases, a healthy lifestyle, including a balanced diet, regular physical exercises, sufficient sleep and cognitive stimulation, is a more effective way to maintain and improve cognitive functions.

• Myth 2: All dietary supplements are safe for the brain, as they are «natural».

  • Reality: «Natural» does not mean «safe». Many plant extracts and other dietary supplements can have side effects and interact with medicines. It is important to carefully study the composition of dietary supplements and consult a doctor before taking them, especially if you have any diseases or you take medications. Some dietary supplements may contain impurities or ingredients that are not indicated on the label.

• Myth 3: Bad for the brain can replace medicines for neurodegenerative diseases.

  • Reality: Bad for the brain is not a replacement for drugs from neurodegenerative diseases, such as Alzheimer’s disease or Parkinson’s disease. Medicines used to treat these diseases pass strict clinical trials and have proven effectiveness. Bad can be used as an addition to the main treatment, but only on the recommendation of a doctor.

• Myth 4: The larger the dose of dietary supplements, the better the effect.

  • Reality: High doses of dietary supplements do not always lead to a better effect and can even be harmful. It is important to observe the recommended doses indicated on the product label and consult a doctor to determine the optimal dose for you. Some dietary supplements can be toxic in high doses.

• Myth 5: Bad for the brain have an immediate effect.

  • Reality: Most dietary supplements for the brain have no immediate effect. To achieve the desired effect, it may take several weeks or months of regular admission. In addition, the effect of dietary supplements can be individual and depend on many factors, such as age, health, lifestyle and genetics.

• MIF 6: All statements about the benefits of the human beads are confirmed by scientific research.

  • Reality: Many allegations of the benefits of the Bad for the brain are not confirmed by scientific research. Drual manufacturers often use marketing strategies to attract consumers, while not having sufficient scientific evidence of the effectiveness of their products. It is important to critically evaluate information about dietary supplements and rely on scientifically sound data.

Section 4: risks and side effects of dietary supplements for the brain

Reception of dietary supplements for the brain carries certain risks and can cause side effects. It is important to consider these risks before starting dietary supplements.
