Reply to “Ayahuasca turned on my mind’s eye”: A case of acquired versus congenital aphantasia, as evidenced with DMT use?
Abstract
In a recent article in this journal, Dos Santos et al. (2018) report a case of ayahuasca use by a man with aphantasia. This account is the first such report of the use of a psychedelic agent by someone with aphantasia. Surprisingly, the case, SE, reported an improvement in their visual imagery following one particular instance of ayahuasca use. In support of Dos Santos et al.’s (2018) favored psychological explanation for improvement and their suggestion that SE’s aphantasia was acquired rather than congenital, this letter reports on a case study of an individual with apparent congenital aphantasia who has experienced no visual imagery, despite reported having excessively smoked N,N-dimethyltryptamine. It is proposed that the theoretical distinction between acquired and congenital aphantasia be further explored with regard to the use of psychedelics. In addition, further research with psychedelics should include self-report measures that can index aphantasia, such as the Vividness of Visual Imagery Questionnaire, as well as behavioral tasks, such as those measuring binocular rivalry.

Exploring Aphantasia and Psychedelics: A New Perspective
Overview/Introduction
Methodology
- SE, who had acquired aphantasia and reported improved visual imagery after using ayahuasca.
- HE, who had congenital aphantasia and experienced no change despite using DMT over 1,000 times.
Key Findings
- SE's Experience: SE's aphantasia appeared to be acquired, possibly linked to childhood trauma. After using ayahuasca, SE reported an improvement in visual imagery, suggesting that psychedelics might help resolve psychological barriers.
- HE's Experience: HE's aphantasia seemed congenital, with no change in visual imagery despite extensive DMT use. This suggests that congenital aphantasia might have a biological basis that psychedelics cannot alter.
Implications
- Potential for Treatment: The findings suggest that psychedelics like ayahuasca might help individuals with acquired aphantasia, possibly by addressing underlying psychological issues.
- Further Research: The study highlights the need for more research into the differences between acquired and congenital aphantasia and how psychedelics might affect each type differently.
Limitations
- Case Study Nature: The research is based on individual case studies, which limits the generalizability of the findings.
- Self-Reported Data: The reliance on self-reported experiences may introduce biases or inaccuracies.
