Discover the complex interplay of genetics and environment in ADHD susceptibility. Learn how circadian rhythm and neurotransmitter genes contribute to the disorder, and how toxicant exposure may increase risk.
Creatine is an amino acid used in muscle tissue and the brain for energy in times of stress. Genes play a role in creatine synthesis. Find out what the research shows about creatine supplements for muscle mass and cognitive function.
We have many systems in place to control blood pressure and heart rate. The ADRA1A receptors are part of this system. Discover how variants can influence blood vessel stress response and how others are connected to cognitive changes.
Tryptophan is an amino acid that the body uses to make serotonin and melatonin. Genetic variants can impact the amount of tryptophan that is used for serotonin. This can influence mood, sleep, neurotransmitters, and immune response.
GABA (gamma-Aminobuyteric acid) is a neurotransmitter that acts to block or inhibit a neuron from firing. It is an essential way that the brain regulates impulses, and low GABA levels are linked with several conditions, including anxiety and PTSD.
