Dietary supplement to improve memory and concentration in adults: review and analysis

Section 1: Understanding of cognitive functions and their reduction

• 1.1 Cognitive functions: General definition and components. Cognitive functions cover a wide range of mental processes that allow us to perceive, process, remember and use information. The main components include:

  • Attention: The ability to selectively focus on certain information, ignoring distracting factors.
  • Memory: The ability to encode, store and extract information. It is divided into short -term, long -term, working, episodic, semantic and procedural memory.
  • Executive functions: A set of cognitive processes necessary for planning, organization, making decisions and solving problems. Include cognitive flexibility, brake control and working memory.
  • Information processing speed: The speed with which we perceive and process information.
  • Language functions: The ability to understand and use language.
  • Visual-spatial functions: The ability to perceive and manipulate visual objects and spatial relations.

• 1.2 Factors affecting cognitive functions. Cognitive functions are affected by many factors, both internal and external.

  • Age: With age, natural changes in the brain occur, which can lead to a decrease in cognitive functions, such as memory and speed of information processing.
