Antioxidants like vitamins to protect memory from aging

Section 1: brain aging and cognitive decline: fundamental processes

Acting is an inevitable biological process that affects all organs and systems, including the brain. With age, various changes in the structure and functions of the brain occur, which can lead to a cognitive decline, including a deterioration in memory. Understanding these changes is necessary for the development of effective strategies for protecting the brain from aging.

  • 1.1 age -related changes in the structure of the brain:

    With age, there is a decrease in the volume of the brain, especially in areas responsible for memory and cognitive functions, such as hippocampus and prefrontal bark. This reduction is associated with the loss of neurons (nerve cells) and synapses (connections between neurons). A decrease in the volume of white matter, which consists of myelinized nerve fibers, also affects the rate of transmission of nerve impulses.

    • 1.1.1 Loss of neurons and synapses:

      Neurons are the main functional units of the brain. With age, their number is reduced, and the number of synapses that provide the relationship between neurons is reduced. This leads to a decrease in the efficiency of processing and transmitting information.

    • 1.1.2 Reducing the volume of white matter:

      The white matter consists of myelinized nerve fibers, which provide the rapid transmission of nerve impulses. With age, demyelinization occurs, that is, the destruction of the myelin shell, which slows down the speed of information transmission.

    • 1.1.3 Atrophy of the hippocampus and prefrontal bark:

      Hippocampus plays a key role in the formation of new memories and spatial orientation. The prefrontal cortex is responsible for executive functions, such as planning, decision -making and working memory. Atrophy of these areas of the brain leads to a deterioration in memory and cognitive functions.

  • 1.2 age -related changes in the functions of the brain:

    In addition to structural changes, changes in the functions of the brain occur with age, such as a decrease in the speed of information processing, deterioration of working memory and attention.

    • 1.2.1 Reducing the speed of information processing:

      The speed with which the brain processes information slows down with age. This can be manifested in a slow reaction, difficulties in solving complex problems and slowdown.

    • 1.2.2 Deterioration of working memory:

      Working memory is the ability to hold and manipulate information in the mind for a short period of time. With age, the capacity and efficiency of working memory worsens, which complicates the performance of tasks that require the simultaneous maintenance and processing of information.

    • 1.2.3 Reducing attention:

      Attention is the ability to concentrate on a specific task or information, ignoring distracting factors. With age, the ability to maintain attention is reduced, which leads to increased distractivity and difficulties in performing tasks requiring concentration.

  • 1.3 risk factors of cognitive decline:

    There are a number of factors that can increase the risk of cognitive decline, including genetic predisposition, cardiovascular disease, diabetes, obesity, smoking, insufficient physical activity, low level of education and social activity.

    • 1.3.1 Genetic predisposition:

      Genetics plays an important role in determining the risk of cognitive decline. Some genes, such as the Aopolipoprotein gene (APOE), are associated with an increased risk of developing Alzheimer’s disease and other forms of dementia.

    • 1.3.2 Cardiovascular diseases:

      Cardiovascular diseases, such as hypertension, atherosclerosis and stroke, can damage blood vessels in the brain, which leads to a decrease in blood supply and oxygen starvation of neurons. This increases the risk of cognitive decline.

    • 1.3.3 Diabetes and obesity:

      Diabetes and obesity are associated with an increased risk of developing insulin resistance, inflammation and oxidative stress in the brain, which can damage neurons and lead to a cognitive decline.

    • 1.3.4 smoking:

      Smoking damages blood vessels and reduces blood supply to the brain, which increases the risk of cognitive decline and the development of dementia.

    • 1.3.5 insufficient physical activity:

      Regular physical activity improves blood supply to the brain, stimulates neurogenesis (the formation of new neurons) and reduces the risk of cardiovascular diseases, diabetes and obesity. Insufficient physical activity increases the risk of cognitive decline.

    • 1.3.6 Low level of education and social activity:

      A high level of education and active social life stimulate the brain and support cognitive functions. Low level of education and social isolation increase the risk of cognitive decline.

Section 2: Oxidative stress and its role in brain aging

Oxidative stress is an imbalance between the formation of free radicals (unstable molecules that can damage cells) and the body’s ability to neutralize them using antioxidants. Oxidative stress plays an important role in brain aging and the development of neurodegenerative diseases.

  • 2.1 Free radicals and their education:

    Free radicals are formed as a result of normal metabolic processes, as well as under the influence of external factors, such as environmental pollution, smoking, ultraviolet radiation and inflammation.

      In the process of cellular respiration and other metabolic reactions, free radicals form as by -products.

    • 2.1.2 External factors:

      Environmental pollution, smoking, ultraviolet radiation and inflammation enhance the formation of free radicals in the body.

  • 2.2 Cell damage with free radicals:

    Free radicals can damage various components of cells, including DNA, proteins and lipids (fats). This damage can lead to impaired cell function and their death.

    • 2.2.1 DNA damage:

      Free radicals can cause mutations in DNA, which can lead to disruption of cell function and cancer development.

    • 2.2.2 protein damage:

      Free radicals can modify proteins by changing their structure and function. This can lead to a violation of the work of enzymes, transport proteins and structural proteins.

    • 2.2.3 Lipid damage:

      Free radicals can oxidize lipids that form cell membranes. This leads to a violation of the structure and function of membranes, which can lead to a violation of the transport of substances through the membrane and the death of cells.

  • 2.3 oxidative stress and aging of the brain:

    The brain is especially vulnerable to oxidative stress due to a high level of metabolism, a large content of lipids and a relatively low level of antioxidant protection. Oxidative stress plays an important role in the aging of the brain and the development of neurodegenerative diseases, such as Alzheimer’s disease and Parkinson’s disease.

    • 2.3.1 Alzheimer’s disease:

      Oxidative stress plays an important role in the pathogenesis of Alzheimer’s disease. Free radicals can contribute to the formation of amyloid plaques and neurofibrillar balls, which are characteristic signs of this disease.

    • 2.3.2 Parkinson’s disease:

      Oxidative stress also plays a role in the development of Parkinson’s disease. Free radicals can damage dopaminergic neurons in the black substance of the brain, which leads to the development of symptoms of this disease.
