Can Aphantasia be treated?
There is no strong evidence that it can. No reliable method exists for producing voluntary visual imagery in people with lifelong aphantasia. It would be dishonest to suggest otherwise.
Some people try various practices and report subjective changes. The research does not back up the idea that those practices produce actual mental imagery in people who have never had it.
It is understandable to want to fix aphantasia immediately. However, that desire often leads in the wrong direction. The goal of fixing aphantasia and the goal of adapting to it are completely different. Only one of them is actionable right now.
Adaptation works. There are concrete strategies that change outcomes in classrooms and at home. These strategies do not require a person to suddenly generate mental images.
Most people with lifelong aphantasia are not suffering. They have always thought this way. Friction occurs when people use tools that assume a working mind eye. Remove that mismatch and most of the friction disappears.
