Cognition and Brain Health Genetic Test
See how your DNA shapes focus, memory, and mood, plus the way your body ages, and turn those insights into guidance you can act on.
Genetic Tests are a one-time purchase
The Cognition and Brain Health Genetic Test turns one cheek swab into 120+ DNA insights across 91 genes, covering focus, memory, and mood plus how your genes shape the way your skin, joints, and senses age over time.
What your DNA reveals in this test
Focus, memory & mental clarity
How your genes may shape attention, mental speed, and memory, including BDNF for memory and mood. A practical starting point for understanding your everyday cognitive patterns.
Mood & emotional balance
How your genes may shape mood, stress sensitivity, and emotional steadiness, including the stress-hormone receptor CRHR1. Useful context for conversations with your provider.
Brain chemistry & motivation
How your body makes and clears brain chemicals like dopamine, serotonin, and norepinephrine, including the well-known COMT gene. Context for focus, motivation, and reward.
Skin & visible aging
How your genes may shape skin elasticity, fine lines, sun-related skin changes, and hair pigmentation over time, including the pigment gene MC1R. Helpful background for your skincare choices.
Joints, bones & inflammation
How your genes may relate to joint comfort, bone density, tendon resilience, and your everyday inflammatory tendency, including LRP5 for bone. Context to discuss with your provider.
Sensory, oral & metabolic aging
How your genes may relate to hearing and balance, vision and eye health, gum and oral health, and everyday energy as you age. A starting point for prevention where it matters most.
What this test covers
This test analyzes your DNA across the Cognition & Brain Health and Healthy Aging reports: 129 markers across 29 traits, grouped into the six areas below. It covers brain health and the ways your body ages.
Focus, memory & mental clarity
How your genes may shape attention, mental speed, and memory. This area covers focus, learning, and recall, including BDNF for memory and mood and CHRNA4 for attention.
Mood & emotional balance
How your genes may shape mood, stress sensitivity, and emotional steadiness, including the stress-hormone receptor CRHR1.
Brain chemistry & motivation
How your body makes, signals, and clears brain chemicals like dopamine, serotonin, and norepinephrine. The well-known COMT gene sits here, alongside the dopamine and serotonin pathways.
Skin & visible aging
How your genes may shape skin elasticity, fine lines, sun-related skin changes, and hair pigmentation over time, including the well-known pigment gene MC1R and the elastin gene ELN.
Joints, bones & inflammation
How your genes may relate to joint comfort, bone density, tendon resilience, and your everyday inflammatory tendency, including LRP5 for bone and the vitamin D receptor VDR.
Sensory, oral & metabolic aging
How your genes may relate to hearing and balance, vision and eye health, gum and oral health, and everyday energy as you age, including CFH for vision and KCNE1 for hearing.
You do not have to act on all of it. Pick one or two areas, talk them over with your provider, and focus where it matters most. This test is for wellness and education, not diagnosis.
