Overview of the best dietary supplements for memory and attention: in -depth analysis

I. Understanding memory and attention: Fundamentals and processes

1. Memory neurobiology:

   • Working memory: Short -term storage and manipulation of information required for current tasks. The prefrontal bark, the parietal bark, and the front waist bark are involved. Functional features include a limited volume (7 +/- 2 elements), active support of attention and vulnerability to distraction.

   • Short -term memory: Temporary storage of information received from the senses. The duration of storage is a few seconds. Associated with sensory registers and does not require active attention.

   • Long -term memory: Storage of information for a long period of time. Divided into:

     • Declarative (obvious) memory: Conscious recalling of facts and events.
       • Episodic memory: Memories of personal experiences and events (for example, what you ate for breakfast). Hippocampus plays a key role in the formation and consolidation of episodic memories.
       • Semantic memory: General knowledge about the world, facts, concepts and meanings of words (for example, the capital of France). Cortical areas (temporal and parietal bark) participate in the storage of semantic information.
     • Non -coolate (implicit) memory: Unconscious training and skills.
       • Procedure memory: Skills and habits (for example, cycling). Basal ganglia and cerebellum are important for procedural training.
       • Price: The influence of previous experience on the subsequent reaction.
       • Classic determination: Associative training (for example, Pavlov’s reflex).
       • Non -accerative training: Addition and sensitization.

   • Memory consolidation: The process of stabilizing memories after their formation, the transformation of short -term memory into long -term. Hippocampus plays a critical role in the early stages, gradually transferring memories to the cerebral cortex for long -term storage.

   • Neuroplasticity: The ability of the brain to change the structure and function in response to experience. Sinaptic plasticity (a change in the connection force between neurons) underlies training and memory. Long -term potential (LTP) and long -term depression (LTD) are the main mechanisms of synaptic plasticity.

   • Neurotransmitter: Chemicals transmitting signals between neurons. Acetylcholine, glutamate, dopamine, serotonin and norepinephrine play an important role in learning and memory processes.

2. Neurobiology of attention:

   • Attention: A selective process of focusing on certain incentives or information, ignoring others. It is necessary for awareness, training and completing tasks.
   • Types of attention:
     • Selective attention: The ability to focus on one stimulus, ignoring others (for example, a conversation in a noisy room).
     • Sustainable attention: The ability to maintain concentration for a long period of time (for example, reading a book).
     • Separated attention: The ability to simultaneously pay attention to several tasks (for example, driving a car and conversation by phone).
     • Switching attention: The ability to quickly switch between different tasks or stimuli.
   • Brain structures involved in attention:
     • Prefrontal bark: Executive functions, planning, decision -making, working memory and attention control. Dorsolateral prefrontal cortex (DLPFC) is especially important for working memory and cognitive control.
     • Parietal bark: Spatial attention, processing of sensory information and integration of sensory stimuli. The rear parietal bark (PPC) is involved in visual attention and switching attention.
     • Lumbar the bark: Detection of errors, conflict monitoring and regulation of motivation. The front waist cortex (ACC) is important for cognitive control and conflict resolution.
     • Talamus: Relay station for sensory information, filtering and direction of attention.
     • Reticular formation: Regulation of the level of wakefulness and attention.
     • Upper Bugor: Management of eye movements and switching attention to new incentives.
   • Neurotransmitters in attention: Dopamine and norepinephrine play a key role in the regulation of attention, motivation and vigilance. Acetylcholine is also important for attention and learning.
   • Attention theories:
     • Filter Theoria (Broadbent): It suggests that the information is filtered in the early stages of processing.
     • Weakening theory (Treisman): It suggests that unwanted information is weakened, not completely blocked.
     • Late selection model (Deutsch & Deutsch): It suggests that all information is processed, but only relevant information falls into the mind.
   • Factors affecting attention: Fatigue, stress, sleep, medicine, age and neurological disorders (for example, ADHD).

3. Factors affecting memory and attention:

   • Age: With age, changes in the structure and functions of the brain occur, which can lead to a decrease in cognitive functions, including memory and attention. The volume of hippocampus and prefrontal cortex decreases, the level of neurotransmitters decreases and neuroplasticity worsens.
   • Dream: The lack of sleep negatively affects the consolidation of memory, attention and executive functions. During sleep, the brain processes and consolidates information, and is also cleared of metabolic waste.
   • Stress: Chronic stress can damage the hippocampus and prefrontal bark, worsening memory and attention. Cortisol, stress hormone, can have a toxic effect on neurons.
   • Nutrition: The deficiency of certain nutrients can negatively affect cognitive functions.
   • Physical activity: Regular physical exercises improve the blood supply to the brain, increase the production of neurotrophic factors (for example, BDNF) and contribute to neuroplasticity.
   • Cognitive stimulation: Active training, reading, games and other types of cognitive stimulation can help maintain and improve cognitive functions.
   • Diseases: Some diseases, such as Alzheimer’s disease, Parkinson’s disease, stroke, depression and ADHD, can negatively affect memory and attention.
   • Medicines: Some drugs can have side effects that affect cognitive functions.
   • Genetics: Genetic factors can play a role in predisposition to cognitive impairment.

II. Overview of key components of dietary supplements for memory and attention:

1. Nootropics:

   • Piracetam: One of the first nootropes improves cognitive functions, especially memory and training. The alleged mechanism of action includes an improvement in the fluidity of neurons membranes and an increase in cerebral blood flow.

Some studies show a positive effect on cognitive functions in older people and patients with cognitive impairment, while other studies do not detect a significant effect.

   • Aniracetam: More powerful than piracetams also improves memory and training. Presumably, the aniracetes stimulates ampa receptors and affects the release of acetylcholine. Some studies show that aniracetes can improve cognitive functions in patients with Alzheimer’s disease and other cognitive disorders.

   • Oxiracetam: Improves memory, attention and concentration. The mechanism of action is similar to piracetams and aniracetes.
