Recent scientific studies reveal a counterintuitive trend: the brain's main inhibitory neurotransmitter, GABA, does not increase with age. Instead, GABA levels and the efficiency of its signaling system tend to decline over time, influencing cognitive function, mood, and sleep.
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.
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.
According to the World Health Organization, approximately 14% of adults aged 60 and over live with a mental disorder. As people get older, their bodies and brains change, leading to questions like, "Does hangxiety get worse with age?" This guide explores the scientific reasons behind this phenomenon and offers strategies for coping.
