Brain health after 40: a comprehensive guide for the preservation and improvement of cognitive functions

I. Age -related brain changes: reality and possibilities

Starting from 40 years, natural changes occur in the human brain. It is important to understand that these changes do not necessarily lead to a decrease in cognitive abilities. Rather, this is a transition to a new stage, which requires a more conscious approach to maintaining brain health.

A. Structural changes:

Reducing the volume of the brain: The total volume of the brain, especially in the prefrontal cortex (responsible for planning, making decisions and working memory) and hippocampus (playing a key role in the formation and consolidation of memory), can slightly decrease. This is due to a decrease in the number of neurons and synapses, as well as with a reduction in the amount of myelin – the fat membrane that isolating the nerve fibers and accelerates the transmission of nerve impulses.
Reduced neurogenesis: Neurogenesis, the process of formation of new neurons, continues in adulthood, but its intensity gradually decreases with age. In particular, in the hippocampus where neurogenesis occurs, this process can slow down, which potentially affects training and memory.
Changes in white matter: The white substance of the brain, consisting of myelinized nerve fibers, also undergoes changes. Milin may be damaged, which leads to a slowdown in the transmission of information between different areas of the brain.
Beta-amyloid and tau-white accumulation: Beta-amyloid and tau-white are proteins, which, with improper disposal, can accumulate in the brain, forming plaques and balls, respectively. These formations are associated with the development of Alzheimer’s disease and other neurodegenerative diseases. It is important to note that the presence of these proteins does not necessarily mean the development of the disease, but increases the risk.

B. Functional changes:

Slow down the speed of information processing: The speed with which the brain processes information can slow down slightly. This is manifested in a more slow response to incentives, an increase in the time necessary for solving problems, and some decrease in the speed of training in new skills.
Reduced working memory: Working memory, the ability to hold and manipulate information in the mind, can also weaken. This can lead to difficulties in memorizing sequences, performing complex tasks and tracking several tasks at the same time.
Reduced attention: The ability to concentrate attention and ignore distracting factors can decrease. This can be manifested in difficulties with a concentration on reading, watching films or performing tasks that require concentration.
Deterioration of episodic memory: The episodic memory, which is responsible for memorizing specific events and experiences, can worsen. This can be manifested in difficulties with memorizing names, persons, dates and other details of events.
Preservation of semantic memory: The semantic memory, which is responsible for general knowledge and facts, is usually preserved well. People continue to accumulate and use knowledge throughout their lives.
Preservation of procedural memory: The procedural memory responsible for remembering skills and motor sequences is also usually preserved well. For example, people continue to ride a bicycle, play musical instruments or cook their favorite dishes, even with age.

C. Factors affecting age -related changes:

Genetics: A genetic predisposition plays a significant role in determining the speed and degree of age -related changes in the brain. The presence of genes associated with an increased risk of developing neurodegenerative diseases can accelerate cognitive decline.
Life: The lifestyle has a huge effect on the health of the brain. Healthy nutrition, regular physical exercises, sufficient sleep, stress management and intellectual activity can slow down age -related changes and improve cognitive functions.
Diseases: Some diseases, such as diabetes, hypertension, cardiovascular diseases and depression, can negatively affect brain health and accelerate cognitive decrease.
Head injuries: Clurry injuries, especially repeating, can increase the risk of cognitive impairment and neurodegenerative diseases in the future.
Bad habits: Smoking, alcohol abuse and drug use have a destructive effect on the brain and accelerate the cognitive decline.
Social isolation: Social isolation and lack of social ties can negatively affect the health of the brain and increase the risk of cognitive impairment.

D. Plastity of the brain: the ability to improve

Despite age -related changes, the brain has an amazing ability to plan – the ability to adapt, reorganize and form new connections between neurons. This plasticity is preserved throughout life and allows you to improve cognitive functions even in old age.

Neuroplasticity: Neuroplasticity means that the brain can change its structure and function in response to a new experience, training and stimulation.
Compensation: If one area of the brain is damaged or weakened, other areas can compensate for the lost functions.
Formation of new synapses: The brain can form new synapses, connections between neurons, which allows you to improve training and memory.
Increase in brain volume: In response to training and stimulation, the volume of some areas of the brain may increase.

Understanding the plasticity of the brain inspires optimism and emphasizes the importance of an active approach to maintaining cognitive health.

II. Nutrition for brain health: Fuel for optimal function

Proper nutrition plays a key role in maintaining brain health. The brain requires a constant influx of energy and nutrients for optimal functioning.
