Gamma-aminobutyric acid (GABA) is an important neurotransmitter in the human central nervous system, playing a key role in regulating nerve excitability. This substance belongs to the class of inhibitory neurotransmitters, which means its ability to reduce neuronal activity, thereby having a calming, anticonvulsant, and relaxing effect on the body. GABA is synthesized in the brain from glutamate, another neurotransmitter, by the enzyme GABA transaminase. This neurotransmitter is involved in many processes, including the regulation of sleep, mood, and muscle tone.
Abnormalities in the GABA system have been linked to a variety of neurological and psychiatric diseases, such as epilepsy, anxiety disorders, depression, and insomnia. In medical practice, drugs that affect the GABAergic system are used to treat these conditions. For example, benzodiazepines, which enhance the effects of GABA, are used as sedatives and anticonvulsants. GABA supplements are also being researched, which may have a relaxing effect and improve sleep quality. However, it is important to remember that the use of any drugs that affect the GABAergic system must be done under strict medical supervision.
