There is no strong evidence that it can. No reliable method exists for producing voluntary visual imagery in people with lifelong aphantasia, and it would be dishonest to suggest otherwise. Some people try various practices and report subjective changes, but the research does not back up the idea that those practices produce actual mental imagery in people who have never had it.

This is worth saying clearly because a lot of people who find out about aphantasia immediately want to fix it, which is understandable but leads in the wrong direction. The goal of fixing aphantasia and the goal of adapting to it are completely different, and only one of them is actionable right now. Adaptation works, and there are concrete strategies that change outcomes in classrooms, in therapy, and at home without requiring a person to suddenly generate mental images.

The other thing worth saying is that most people with lifelong aphantasia are not suffering. They have always thought this way, and what causes friction is not aphantasia itself but being handed tools that assume a working mind's eye. Remove that mismatch and most of the friction disappears.
