Dietary supplement to improve memory under stress: review, scientific data and practical recommendations
I. Stress and its influence on memory: neurobiological mechanisms
Stress, defined as the physiological and psychological reaction of the body to the perceived threat or challenge, has a deep effect on cognitive functions, especially on memory. Understanding the neurobiological mechanisms through which stress affects memory is crucial for the development of effective strategies, including the use of biologically active additives (BADs) aimed at mitigating these negative effects.
-
Hypothalamus-wire-wounds axis (HPA): Activation of the HPA axis is a central component of a stress response. In the perception of stress, the hypothalamus releases the corticotropin-rilying hormone (CRH), which stimulates the pituitary gland to the secretion of adrenocorticotropic hormone (ACTH). ActH, in turn, stimulates the adrenal glands to the production of cortisol, the main stress hormone. A short -term increase in the level of cortisol can improve some cognitive functions, such as vigilance and concentration, but chronic stress leads to a prolonged effect of cortisol, which has a devastating effect on the brain.
-
The influence of cortisol on hippocampus: Hippocampus, the area of the brain, critical for the formation and consolidation of new memories, is especially vulnerable to the effects of cortisol. The chronically increased level of cortisol can:
- Suppress neurogenesis: Neurogenesis, the process of formation of new neurons, occurs in the hippocampus of an adult brain. Chronic stress and a high level of cortisol suppress neurogenesis, reducing the plasticity of the brain and the worsening ability to form new memories. Studies on animals and people have shown that a stress-induced decrease in neurogenesis correlates with a deterioration in spatial memory and other cognitive deficits.
- Call atrophy of dendrites: The dendrites, branching processes of neurons receive signals from other neurons. Chronic stress leads to atrophy of dendrites in the hippocampus, which reduces the number of synaptic connections and reduces the effectiveness of information transmission. This structural change affects the ability of the hippocampus to process and store information, worsening memory.
- Strengthen glutamatergic toxicity: Glutamate is the main exciting neurotransmitter in the brain. Under the influence of chronic stress and a high level of cortisol, the release of glutamate can be excessive, leading to exaytotoxicity-damage and death of neurons due to excessive stimulation. Excetotoxicity is especially dangerous for the hippocampus, making it more vulnerable to damage caused by stress.
- Involve the long -term potential (LTP): LTP is a mechanism underlying training and memory, which is an increase in synaptic connections between neurons. Stress can violate LTP in the hippocampus, preventing the process of memory consolidation and the worsening ability to form long -term memories.
-
The effect of stress on the prefrontal bark: Prefrontal cortex (PFC), the area of the brain that is responsible for the highest cognitive functions, such as decision -making, planning and working memory, is also affected by stress. Chronic stress can:
- Reduce dopaminergic alarm: Dopamine is a neurotransmitter that plays an important role in motivation, attention and working memory. Stress reduces the release of dopamine in PFC, which leads to a deterioration in working memory, a decrease in cognitive flexibility and difficulties in making decisions.
- Worsen the functioning of neural networks: PFC consists of complex neural networks that allow you to carry out complex cognitive processes. Stress can violate the functioning of these networks, reducing the effectiveness of communication between different PFC areas and a worsening ability to purposeful behavior.
- Enhance impulsiveness: Stress can weaken PFC control over lower areas of the brain, such as amygdala, which leads to an increase in impulsivity and a decrease in the ability to control emotions and behavior.
-
The role of inflammation: Stress can cause an inflammatory reaction in the brain, which can also negatively affect memory and cognitive functions. Inflammatory cytokines, such as Interleukin-1β (IL-1β) and the factor of tumor necrosis-α (TNF-α), can disrupt synaptic plasticity, suppress neurogenesis and promote neurodhevation.
-
Impact of Amigdalu: Amigdala, the area of the brain, responsible for the processing of emotions, especially fear and anxiety, can be excessively activated in stress. This hyperactivation can distract the brain resources from other cognitive functions, including memory, which leads to a deterioration in memorization and reproduction of information.
II. Bades to improve memory under stress: Scientific review
