Creatine Activity as a Neuromodulator in the Central Nervous System

Area of Science:

• Neuroscience
• Nutritional Biochemistry
• Cognitive Science

Background:

• Creatine is a nutritional compound with potential cognitive and neuroprotective effects.
• Emerging evidence suggests creatine functions as a neuromodulator, released similarly to neurotransmitters.
• Creatine deficiency syndromes highlight its critical role in brain development and function.

Purpose of the Study:

• To review experimental data and clinical observations on creatine's role in central nervous system transmission.
• To explore creatine's influence on cognitive health, performance, and neuroprotection.
• To investigate creatine's potential interaction with neurotransmitter systems.

Main Methods:

• Systematic literature search across major scientific databases (PubMed, Scopus, Embase, Cochrane, Web of Science, Google Scholar).
• Utilized MeSH terms including Creatine, Phosphocreatine, Bioenergetics, Nervous system, Brain, Cognition, and Neuroprotection.
• Analysis of experimental and clinical evidence regarding creatine's neurological effects.

Main Results:

• Exogenous creatine supplementation reduces neuronal cell loss in models of neurological diseases.
• Creatine interacts with key neurological receptors and enzymes, including NMDA, GABA_A, and serotonin 1_A receptors.
• Evidence supports creatine's critical role in central nervous system transmission processes.

Conclusions:

• Creatine demonstrates significant neuroprotective effects, enhancing cognition, memory, and spatial memory.
• Creatine's interactions with various receptors indicate its function as a neuromodulator.
• Further research confirms creatine's potential as a therapeutic agent for neurological conditions.
