Does GABA Decrease as You Age? Understanding the Neurotransmitter's Lifespan Trajectory

According to extensive research, the brain’s concentration of Gamma-aminobutyric acid (GABA), the primary inhibitory neurotransmitter, does indeed follow a non-linear trajectory throughout life, typically culminating in a gradual decrease after midlife. This trend has significant implications for understanding the changes associated with healthy aging.

Does GABA Decline with Age? Understanding Its Impact on Healthy Aging

According to a 2024 longitudinal study, a significant decline in GABA levels occurs as healthy older adults age, even after controlling for differences in brain tissue composition. This finding supports the idea that the brain's chief inhibitory neurotransmitter diminishes over time. The question, "**Does GABA decline with age?**", is therefore critical for understanding healthy brain function throughout the lifespan.
