Stress to protect the brain from stress: complex review and scientific analysis
Section 1: Stress and its effect on the brain
Stress is a natural reaction of the body to requirements and environmental challenges. In moderate quantities, it can even be useful, stimulating activity and increasing performance. However, chronic or excessive stress has a destructive effect on various body systems, especially on the brain. Understanding the mechanisms of this impact is critical of the development of effective protection strategies.
1.1. Physiology of stress: Hypothalamus-guip-adapter axis (HPA)
A key role in the reaction to stress is played by the axis of the hypothalamus pituitary-adapted (HPA). In the perception of the threat, the hypothalamus is highlighted by corticoliberin (CRH), which stimulates the pituitary gland to the production of adrenocorticotropic hormone (ACTH). ActH, in turn, affects the adrenal glands, forcing them to release cortisol, the main hormone of stress. Cortisol provides the body with energy, increases blood pressure and suppresses inflammation, preparing it for the reaction of «Behas». However, with prolonged stress, a chronically increased level of cortisol has a negative effect on the brain.
1.2. Neurochemical changes in stress
Chronic stress leads to an imbalance of neurotransmitters, chemicals that transmit signals between nerve cells. Systems associated with dopamine, serotonin and norepinephrine, which play an important role in the regulation of mood, motivation, sleep and cognitive functions, are especially strong.
- Dofamine: Stress can disrupt the dopaminergic system, leading to a decrease in motivation, an angedonia (loss of ability to experience pleasure) and a deterioration in cognitive functions, especially in areas related to decision -making and planning.
- Serotonin: A decrease in serotonin levels is associated with depression, anxiety, irritability and sleep disturbances. Stress can reduce serotonin synthesis and increase its decay, which leads to a deterioration in mood and increasing susceptibility to stress factors.
- Norepinephrine: Initially, stress increases the level of norepinephrine, which improves concentration and attention. However, in chronic stress, the norepinephrine system is depleted, which leads to a deterioration in concentration, increased fatigue and a decrease in the ability to cope with stress.
1.3. The effect of stress on the structure and function of the brain
Chronic stress has a direct effect on the structure and functions of various areas of the brain, in particular on hippocampus, prefrontal cortex and amygdal.
- Hippocampus: Hippocampus plays a key role in the formation of new memories and spatial orientation. Chronic stress suppresses neurogenesis (the formation of new neurons) in the hippocampus and leads to its atrophy. This can be manifested in a deterioration in memory, a decrease in the ability to learn and increased vulnerability to the development of dementia.
- Prefrontal bark: The prefrontal bark is responsible for the highest cognitive functions, such as planning, decision -making, working memory and impulsive control. Stress disrupts the function of the prefrontal cortex, which leads to a deterioration in cognitive abilities, a decrease in concentration, impulsiveness and difficulties in decision -making.
- Amygdala: Amigdala plays a key role in processing emotions, especially fear and anxiety. Stress can increase the activity of amygdaly, which leads to increased anxiety, irritability and tendency to negative emotions.
1.4. Oxidative stress and neuro butter
Chronic stress enhances oxidative stress and neuro butt, which are important mechanisms of brain damage.
- Oxidative stress: Oxidative stress occurs when the balance between the production of free radicals and antioxidant protection is disrupted in favor of free radicals. Free radicals damage brain cells, including neurons, their membranes and DNA, which leads to a violation of their function and death.
- Neuroigation: Nemo -driving is an inflammatory reaction in the brain that occurs in response to damage or infection. Chronic stress activates the immune cells of the brain (microglia and astrocytes), which release inflammatory cytokines. These cytokines can damage neurons and disrupt their function, as well as contribute to the development of neurodegenerative diseases.
Section 2: Bad to protect the brain from stress: action mechanisms and clinical studies
Bades (biologically active additives) can be a useful addition to a healthy lifestyle to protect the brain from the negative effects of stress.
