Cognitive Problems · Cognitive Traits · Cognition Genes
This report reads your DNA and sorts every result into one of five plain-language groups, so you can see at a glance what deserves attention and what does not. Nothing here is a diagnosis. A flagged result means your genetics place you above or below the average person for that trait — a reason to ask a question, not a reason to worry.
Cognition — Cognition, or the mental processes involved in acquiring knowledge and understanding, is a critical aspect of human functioning. From problem-solving and memory to creativity and reasoning, our cognitive abilities shape how we navigate the world.
These are ordered by how closely they relate to your flagged results — not generic health advice. Marrow does not prescribe, dose, or tell you to take anything. Diet and lifestyle changes are listed first because they are yours to make. Anything you would swallow is listed separately, by name only, as something to raise with a clinician who knows your history and your medications.
Ensure you allocate enough time in your schedule to achieve a minimum of 7 hours of sleep each night.
Drink 1 to 3 cups of black coffee daily, preferably in the morning to minimize potential sleep disturbances.
Engage in exercises that challenge your brain for at least 15 minutes per day, five days a week.
Practice yoga for at least 20 to 30 minutes a day, most days of the week.
Engage in strength training exercises, such as weight lifting or bodyweight exercises, for 60 minutes per session, TA 2 to 3 times per week.
Engage in mentally stimulating activities, such as puzzles, reading, or learning a new skill, for at least 15 minutes TA daily.
Incorporate a half to one cup of fresh or frozen blueberries into your daily diet.
Limit red meat to a few times a month and include a moderate amount of dairy products.
TA seated position, close your eyes, focus on your breathing, and observe your thoughts and sensations without judgment.
These came up in the research behind your flagged results. They are listed by name so you can ask about them. Marrow is not recommending them, and gives no dose. Supplements interact with prescription medication and with each other — that conversation belongs with your clinician.
Of the 28 results in this package, these 3 came back furthest from the population average. Each one below explains what it is, where you sit, and which report it came from. Start here.
Key Takeaways: Brain fog is a common symptom of chronic fatigue syndrome.
It manifests as memory problems, difficulty focusing, jumbled or hazy thoughts, and confusion.
Risk factors include stress, sleep problems, air pollution, smoking, and your genetics.
Dyslexia is a learning disorder affecting reading skills.
It involves issues with identifying speech sounds and learning how they relate to letters and words (decoding).
About 40-60% of the differences in dyslexia may be due to genetics.
Named only. Marrow gives no dose and does not recommend these.
Not everything in a genetic report is a warning. These came back protective or better than average.
Mild cognitive decline is a normal part of aging that can affect cognitive functions such as memory, attention, and problem-solving.
About 60-70% of the differences in people’s cognitive decline may come from genetics.
For example, genetically high total and bioavailable testosterone may be causally associated with larger gray matter volume in men [R, R, R].
The influence of genetics may vary by cognitive ability [R, R, R].
Several genes appear to have a connection with the development of ASD.
Between 10% and 20% of cases can be linked to genetic disorders, such as mutations in genes like SHANK3 and genetic conditions like: Down syndrome Rett syndrome Fragile X syndrome.
About 40% of people’s differences in episodic memory may be due to genetics.
The remaining results, grouped by what they mean. Every one of these is explained in full — with the genes and variants behind it — in the technical version of this report.
Genetics is a predisposition, not a verdict. The single most useful thing you can do with this document is take it to a clinician and talk through the flagged findings — especially any that line up with symptoms you already have or conditions that run in your family. Nothing here changes: your DNA is the same at 60 as it is today, so this report does not expire.
Genotyping was performed on DNA extracted from a buccal (cheek) swab using a genome-wide array. Results are derived from peer-reviewed genome-wide association data and, where applicable, published clinical guidelines. Each report was scored independently against its own reference set. Percentile figures describe where your result sits relative to a reference population.
This is a laboratory-developed test. It has not been cleared or approved by the U.S. Food and Drug Administration. Genotyping does not detect all variants in the genes assessed; the absence of a flagged result does not exclude risk. Predisposition is probabilistic and is modified by environment, lifestyle, ancestry and family history. Results must be interpreted by a qualified healthcare professional and must not be used alone to diagnose, treat, or alter any medication regimen. Marrow does not recommend, prescribe, or dose any supplement or medication.
