How to use the materials
Follow the claim back to its measure.
“Brain age” is not a diagnosis or a promise of reversal. It is a family of modelling approaches that may estimate age-related patterns from brain data, and its meaning depends on the dataset, method, population, and outcome being discussed. A definition of neuroplasticity can clarify the concept, but it does not establish that a particular intervention produces durable clinical change.
Our materials encourage readers to keep the setting visible. For example, claims associated with basketball-focused ibogaine narratives or soccer-related accounts may be meaningful to the people telling them, while still leaving unanswered questions about dose, screening, monitoring, follow-up, and causation.
