ADHD is commonly linked with deficits of the neurotransmitter dopamine and deficits in our noradrenergic neurotransmitter system. This system is responsible for the synthesis, storage, and release of norepinephrine.
It is my opinion that ADHD cannot be described by abnormalities of a single neurotransmitter or system. I believe we must care for our entire nervous system all of our chemical messengers equally to effectively manage ADHD.
Let’s take a look at GABA
Gamma-aminobutyric acid (GABA) serves as the main inhibitory neurotransmitter in the human cortex.
The role of GABA is to inhibit or reduce the activity of the neurons or nerve cells. GABA plays an important role in behavior, cognition, and the body's response to stress.
A lack of GABA leaves your central nervous system with too many neuronal signals and causes conditions like anxiety, epilepsy, seizures, increased PMS symptoms, or mood disorders. Low GABA levels have also been linked directly to ADHD, GABA concentration is typically reduced in children with ADHD compared with typically developing control subjects.
During periods of stress, the adrenal glands produce hormones that spark the fight-or-flight responses, such as increased heartbeat or an adrenaline rush. GABA counteracts these natural stimulants by relaxing the brain.
GABA is also known for its analgesic effects, anti-anxiety, and hypotensive activity.
