When it comes to ADHD, no two people experience it exactly the same way. Some struggle with focus, others with restlessness, emotional outbursts, or mental fatigue. That’s because ADHD isn’t just about behavior- it’s often influenced by something deeper. More and more research is showing a strong connection between ADHD and genetics. Certain genetic variants can impact how the brain processes dopamine, serotonin, and other chemicals that affect focus, mood, and attention.
At Genetic Wellness, we use a test called Precision Wellness to take a closer look at the genes that may be playing a role. It’s not about diagnosing ADHD-it’s about understanding what your brain may need to function better.
Let’s break it down.
The Brain Chemicals Behind ADHD
ADHD is often linked to how the brain uses certain neurotransmitters—chemical messengers like dopamine, serotonin, and norepinephrine that help regulate attention, focus, mood, and motivation.
Some of the key genes we look at:
- COMT – Affects how quickly your body breaks down dopamine
- MAOB – Helps process dopamine and other mood-regulating chemicals
- SLC6A4 – Impacts how serotonin is transported in the brain
- HTR2 – Affects how serotonin is received and processed
- GAD1 – Plays a role in producing GABA, which helps calm the brain
Energy, Focus, and Fatigue
We also look at mitochondrial genes—these control how your cells make energy. If your energy system is sluggish, you might feel tired, foggy, or lack motivation.
Important mitochondrial genes include:
- COX5A – Involved in energy production
- SOD2 – Helps neutralize oxidative stress that affects cellular energy
People with variations in these genes may feel like they’re running on low battery all the time, even with plenty of sleep or food.
Inflammation and the Brain
Chronic inflammation isn’t just about joints or digestion. It can affect the brain too. Some people have genes that increase the likelihood of ongoing inflammation.
Genes we check for include:
- IL6 – Linked to systemic inflammation
- NOS2 – Can increase inflammation in the gut and brain
- CTLA4 and TRAF-1 – Also play a role in immune and inflammatory balance
If these genes are active, it might explain mood swings, irritability, or brain fog that don’t respond to typical ADHD treatments.
Nutrients That Support Focus
Certain vitamins and minerals are critical for brain function. If your body can’t absorb or use these nutrients effectively, it can impact mood, attention, and energy.
We test genes that influence:
- B12 transport and usage – including MTRR, TCN2, and GIF
- Folate absorption – such as FOLR1 and SLC19A1
- B vitamin metabolism – including MTHFD1 and DHFR
Even if you eat a healthy diet, you might not be getting what your brain needs if these genes aren’t working efficiently.
Why This Matters
Genetic testing doesn’t diagnose ADHD. But it can help explain what’s going on underneath. It’s a powerful way to understand your body and take steps that actually support how your brain works.
If you or your child struggles with:
- Focus and attention
- Low energy or brain fog
- Mood swings or irritability
- Poor response to ADHD medications
- Trouble sleeping or calming down
This kind of testing can help point you in the right direction.
The Precision Wellness test is simple and done from home. You’ll get a full report and a personal review session so you know exactly what your results mean and what steps to take next.
