Medical disclaimer

Everything BrainFirst publishes — our books, courses, and articles — is for general educational purposes. It describes what current research suggests about how the brain works and how everyday habits can support it. It is not medical advice, and it is not a substitute for diagnosis, treatment, or guidance from a qualified healthcare professional who knows your situation.

Reading our content does not create a doctor–patient, therapist–client, or any other professional relationship between you and BrainFirst or its authors. We cannot know your medical history, medications, or circumstances, so nothing here is tailored to you.

Before you change your diet, sleep, exercise, supplements, or medication — or start any new practice based on something you read here — speak with a doctor or another suitably qualified professional. This is especially important if you are pregnant, managing a health condition, or taking prescribed medication.

If you think you may be experiencing a medical emergency, or you have concerns about symptoms such as sudden confusion, memory loss, severe headache, or changes in mood or thinking, contact your local emergency services or a healthcare professional right away. Do not wait, and do not rely on anything you read on this site.

Brain science moves quickly. We work to reflect the evidence accurately at the time of writing, but research evolves and findings are sometimes revised. We make no guarantee that any particular result described in our content will apply to you.
