When a source uses the word “neuroplasticity,” first identify what was actually measured: a receptor interaction, a cellular change, an animal behavior, or a patient outcome. The more distant the measure is from a real-world health outcome, the more carefully the claim should be framed.
That is especially important for people looking at whether ibogaine treatment works. A mechanism can generate a hypothesis worth studying, while the central questions about benefit, harms, selection, and follow-up remain separate.
Discussion of the evidence review can help keep those categories visible: mechanistic rationale, preclinical findings, human observations, and unanswered questions are not interchangeable levels of support.
