• Explain consequences of increasing and decreasing GABA

  • Sources:

    Gamma-Aminobutyric Acid (GABA) is a major inhibitory neurotransmitter in the brain, helping maintain balance in neural activity. Altering GABA levels can have significant effects:

    1. Increasing GABA:

      • Decreases Anxiety and Excitation: Elevated GABA levels increase inhibition in neuronal pathways, leading to reduced anxiety and neuroexcitability. This effect is beneficial in conditions like epilepsy, where heightened neural activity can lead to seizures. By increasing GABA transmission, as seen in ketogenic diets, seizure frequency can be reduced 1.
      • Induces Relaxation and Sedation: Compounds that enhance GABA activity, such as benzodiazepines or even natural foods like kiwi that interact with the GABA system, can promote relaxation and improve sleep quality by easing transitions into sleep 2.
    2. Decreasing GABA:

      • Increases Anxiety and Excitation: A reduction in GABA can lead to runaway excitation in the brain, increasing anxiety levels. In conditions like OCD or epilepsy, reduced GABA transmission can lead to heightened anxiety and seizure risks, as GABA fails to inhibit excess neural activity 3.
      • Potential Neurological Disorders: Conditions with low GABA, such as epilepsy, demonstrate how crucial this neurotransmitter is for preventing excessive neural firing and associated disorders.

    Overall, maintaining a proper balance of GABA is essential for normal brain function, reducing anxiety, promoting sleep, and preventing excessive neural excitation seen in disorders such as epilepsy.
