Interventions, Training, and Possible Treatments for Aphantasia

A skeptical survey of what people have tried — and what the evidence actually shows.

The honest summary up front: there is no validated treatment for congenital aphantasia. The mainstream researcher consensus (Pearson, Zeman, Keogh, Bartolomeo) is that aphantasia is a cognitive variation rather than a disorder, and there is no evidence-based protocol that reliably converts an aphantasic mind's eye into a phantasic one. The interventions discussed below range from "preliminary case reports worth investigating" to "credulous internet folklore that almost certainly isn't doing what its proponents claim." This document tries to mark each one.

1. Is congenital aphantasia changeable?

The dominant view among the people who actually run the experiments — Joel Pearson at UNSW, Adam Zeman at Exeter, Paolo Bartolomeo in Paris — is that aphantasia is a stable, lifelong trait for the great majority of congenital cases. Brain-imaging work has identified consistent connectivity differences (notably involving the fusiform imagery node and reduced coupling between prefrontal and visual cortex) that look more like a wiring variant than a remediable deficit.

That said, the field is extremely young (Zeman's coining of the term is from 2015), and "no validated treatment" is not the same thing as "definitely impossible." A handful of well-documented cases — single doses of psychedelics, hypnosis trials, and reports from intensive imagery practice — suggest that imagery can sometimes be elicited or strengthened in people who had previously scored at the floor of the VVIQ. None of these have yet been replicated in randomized controlled trials with aphantasic samples and pre/post objective measures.

Bottom line for the personally-affected reader: Skepticism is warranted toward anyone selling a "cure." Cautious experimentation with low-risk practices (meditation, drawing-from-life, structured visualization training) is reasonable. Higher-risk interventions (psychedelics, brain stimulation) are at the case-report stage and should not be treated as routes to predictable change.

2. Image Streaming (Win Wenger)

Image Streaming was promoted by Win Wenger (1929–2021), a self-styled education researcher and author of The Einstein Factor. The technique: close your eyes, describe out loud — in obsessively rich sensory detail — whatever vague visual impressions arise, even if they are dim, fragmentary, or "imagined." The act of verbalizing-while-attending is supposed to bootstrap conscious access to imagery.

Claims: Wenger asserted that Image Streaming raises IQ at a rate of "approximately one point per hour of practice" and that it can produce visual imagery in people who lack it. These are the headline claims that have propelled it through aphantasia forums, Reddit threads, and YouTube tutorials.

Evidence: Essentially none that meets ordinary scientific standards. The "one IQ point per hour" claim traces to an unpublished, uncontrolled student study at Southwest State University in the late 1980s referenced in The Einstein Factor. There is no peer-reviewed RCT, no pre-registered trial, no objective measure (binocular rivalry, priming, pupillometry) showing imagery induction in a verified aphantasic. Anecdotal reports on aphantasia.com and r/Aphantasia are mixed: a small minority report breakthroughs after weeks-to-months of practice, others practice for six months with no change, and the majority dabble and quit.

Honest read: Image Streaming is the most popular intervention in the aphantasia self-help sphere and the one with the weakest formal evidence base. The mechanism (verbal narration prompting attention to faint pre-conscious imagery) is at least theoretically plausible and resembles legitimate aspects of imagery training — but the specific Wenger packaging, the IQ claim, and the breathless tone of its marketing are not science. If you're going to try it, do so with low expectations and a way to objectively benchmark yourself (the VVIQ before and after, ideally a binocular-rivalry test if you can find one).

3. Mind's eye training programs

A more credentialed cluster of work comes out of sport psychology, particularly from Jonathan Rhodes and colleagues at the University of Plymouth, building on Jackie Andrade's Plymouth Sensory Imagery Questionnaire (Psi-Q).

Functional Imagery Training (FIT): Rhodes, Nedza, and collaborators tested FIT — which combines motivational interviewing with structured, multi-sensory, goal-anchored imagery prompts — on 329 athletes across nine sports. They identified 27 low imagers, including 7 with no visual imagery (i.e., visual aphantasia). After a two-week intervention, Psi-Q scores improved significantly, and the effect was maintained at six-month follow-up. A wait-list control group showed no change until they too received FIT.

Caveats: This is encouraging but the right framing is "low imagers improved on a self-report imagery questionnaire," not "aphantasia was cured." Psi-Q is a subjective scale, vulnerable to demand effects after a sustained intervention. The study didn't include objective imagery measures (binocular rivalry, perceptual priming). Still, FIT is the most empirically grounded imagery-training program currently in print, and a reasonable starting point for anyone who wants to attempt structured practice with some scientific scaffolding.

PETTLEP and Observational Imagery: Other sport-psychology techniques (PETTLEP — Physical, Environment, Task, Timing, Learning, Emotion, Perspective) emphasize embodied, multisensory rehearsal. They were not designed for aphantasia and have not been formally tested in aphantasics, but they are mentioned by Rhodes as plausible adjuncts.

General "visualize a red apple" exercises: The standard internet advice (close eyes, picture an apple, focus on color, build detail) has zero published evidence in aphantasic populations. Practitioners often confuse "thinking about an apple" with "seeing an apple," which is exactly the metacognitive ambiguity de Vito & Bartolomeo (2016) flagged a decade ago.

4. Hypnosis case reports

Hypnosis is one of the more theoretically interesting routes because it engages "phenomenological control" — the capacity to alter conscious experience in response to suggestion — which overlaps but does not fully coincide with imagery vividness.

de Vito & Bartolomeo (2016): This paper is frequently cited as a "hypnosis induced imagery" landmark, but the actual claim is more cautious. de Vito and Bartolomeo argued that some aphantasics may not lack imagery so much as lack accurate metacognitive access to it — a self-report problem rather than a sensory absence. They did not publish a definitive case of hypnosis switching imagery on. This is an important nuance: their work supports the plausibility of imagery being recoverable in some subset of self-identified aphantasics, but it is not itself a treatment study.

Lush, Dienes, and colleagues (2024): Used the Phenomenological Control Scale (PCS) and the Sussex Waterloo Scale of Hypnotizability (SWASH) to compare aphantasics and non-aphantasics. Finding: a weak positive correlation between imagery vividness and phenomenological control. Aphantasics were slightly less responsive to imaginative suggestion on average, but the relationship was not deterministic — many aphantasics scored within the normal hypnotizability range. Nobody in this study was reported to have "gained imagery" during hypnosis.

Anecdotal reports of hypnotically-induced imagery exist (clinical hypnotherapists have written about glimpses of imagery during regression work; some EMDR practitioners report similar). None has been published as a controlled case report with pre/post objective imagery measurement.

Honest read: Hypnosis is plausibly useful as an adjunct to therapy for aphantasic clients (the phenomenological control framework gives therapists permission to use suggestion without requiring vivid imagery), and is plausibly worth investigating as an inducer. It is not currently a validated treatment.

5. Psychedelics

This is the area with the strongest preliminary evidence and the strongest ethical concerns.

Dos Santos et al. (2018), Journal of Psychedelic Studies: A 31-year-old man with lifelong aphantasia reported that a single ayahuasca session produced sustained vivid imagery, with effects that persisted for months and were still partially present at follow-up. This is the canonical published case and the one cited everywhere.

Pre-print case (cited by Pearson et al., 2025): A 34-year-old woman with lifelong aphantasia took psilocybin mushrooms and reportedly went from a floor VVIQ score (16/80) to a ceiling VVIQ score (80/80) shortly after the experience. At one-year follow-up her score had drifted down to roughly average — meaning she had moved from aphantasic to typically-imagining and stayed there. This is the most dramatic case in the literature.

Mechanism: 5-HT2A agonism (the receptor mechanism shared by LSD, psilocybin, and DMT) activates the visual cortex even with eyes closed and is thought to trigger neuroplastic changes in cortical connectivity. Pearson speculates psychedelics may either (a) make pre-existing unconscious imagery consciously accessible, or (b) trigger genuine network reconfiguration. He emphasizes that not every aphantasic who takes psychedelics gains imagery — outcomes are variable.

Limits of the evidence: - N=2 published cases plus a handful of anecdotes. - No controlled trials in aphantasic populations. - No baseline objective imagery measures (binocular rivalry, priming) before the dose. - Self-report measures are vulnerable to demand effects, especially after a transformative drug experience.

Risks (Pearson et al., 2025, Cortex): This paper is the closest thing to an authoritative warning. Strong mental imagery correlates with intrusive thoughts, PTSD flashback intensity, maladaptive daydreaming, food cravings, and obsessive rumination. Switching imagery on in someone whose nervous system has spent decades organizing without it could plausibly destabilize sleep, mood, and trauma processing. Pearson explicitly cautions: "people who don't have imagery often think that getting imagery would solve a lot of problems" — but the evidence doesn't support that optimism, and the irreversibility is the concerning part.

Honest read: Psychedelics are the only intervention with clear published case-report evidence of producing durable imagery in an aphantasic. They are also the one most likely to produce outcomes you can't undo. Anyone considering this should be aware that they are running a personal experiment of n=1 with no map.

6. Meditation and sustained visualization practice

Tibetan Buddhist deity-visualization practice (e.g., kyerim) demands extraordinarily detailed and sustained mental imagery, and anecdotal reports from long-term practitioners include strengthened imagery. There are no published studies on aphantasic meditators specifically.

What the research does suggest: Sensory-imagery vividness can shift modestly with sustained practice in non-aphantasic populations. Whether the same applies to people scoring at the VVIQ floor is genuinely unknown. Many aphantasic meditators report that mindfulness and breath-focused practices remain accessible and beneficial even without imagery, but that classical visualization-heavy practices are frustrating.

Honest read: Meditation is low-risk and worth pursuing for its own sake. Whether sustained effort transforms aphantasia is unproven and probably variable. The "neuroplasticity" hand-waving in popular articles ("the brain can be retrained!") does not constitute evidence for aphantasia specifically.

7. Transcranial stimulation (tDCS, TMS)

Keogh, Bergmann, and Pearson (2020, Cortex) showed in non-aphantasic participants that decreasing excitability of early visual cortex (V1–V3) via tDCS increases imagery strength — counterintuitively, lower neural noise produces stronger imagery. The finding has been independently supported.

Critical caveat from Pearson himself: This study did not include aphantasic participants. It is unknown whether the same protocol would induce imagery in someone with congenital aphantasia, and Pearson has explicitly listed this as a future direction. There is no published evidence that tDCS, TMS, or other neuromodulation reverses aphantasia.

Motor-imagery TMS work (2024) shows that aphantasics fail to show the normal increase in corticospinal excitability during motor imagination tasks, consistent with a genuine network-level difference rather than a reporting artifact. This is mechanistic insight, not treatment.

Honest read: Brain stimulation is an active research area with theoretically promising mechanisms, but no clinical protocol exists for aphantasia. DIY tDCS kits sold online for "improving visualization" are not validated, and self-administering electrical stimulation to your skull on the basis of a single non-aphantasic study is unwise.

8. Pharmacological interventions

Outside psychedelics, there is essentially nothing.

No drug has been studied as an aphantasia treatment in any controlled trial.
Ketamine: Anecdotal reports from people undergoing ketamine therapy for depression include some aphantasics noticing imagery during sessions — but these are scattered Medium posts, not data.
SSRIs: A pharmacovigilance signal (FDA Adverse Event Reporting System analysis) has identified aphantasia as a possible adverse effect of antidepressant treatment — i.e., some people on SSRIs report losing imagery they previously had. This is the reverse of what we want, but it is interesting because it implicates serotonin in imagery generation.
Anti-acquired-aphantasia treatment: No published protocol exists for restoring imagery lost to medication.

Honest read: No pharmaceutical route to treating congenital aphantasia exists. The serotonergic story (psychedelics enhance imagery, SSRIs sometimes reduce it) is suggestive of a target system but not yet a therapeutic.

9. Vision therapy / orthoptics

This is a category-error treatment that occasionally gets sold to aphantasics. Orthoptics and behavioral vision therapy address binocular alignment, accommodation, convergence insufficiency, and similar mechanical-optical issues. Aphantasia is a problem of internally-generated imagery, not of visual input — the eyes and primary visual pathway are fine. There is no theoretical or empirical reason to expect orthoptic therapy to help, and no studies have been done. If a vision-therapy clinic offers an "aphantasia program," that should be a major red flag.

10. Acquired aphantasia and recovery cases

Case PL518 (Thorudottir et al., 2020): A 52-year-old architect lost vivid visualization after a bilateral posterior cerebral artery stroke that damaged the fusiform and lingual gyri. Assessed 35 months post-stroke, he scored 18/80 on VVIQ. The paper does not describe meaningful imagery recovery; he had adapted by using computers and verbal/spatial strategies for the architectural work that had previously relied on vivid imagery.

Lesion-network mapping (Mass General Brigham, 2025): Across many cases of acquired aphantasia from varied lesion locations, 100% mapped onto a network connected to the fusiform imagery node. Acquired cases also disproportionately have psychological triggers (62% in one survey reported emotional or psychological precipitants), neurological triggers (41%), or pharmacological triggers (30%) — and many had multiple.

Recovery: The published literature is strikingly silent on recovery trajectories from acquired aphantasia. We know it can happen suddenly and persist for years. We do not have well-documented cases of people regaining imagery years after stroke. This is a significant gap.

Honest read: If you have psychogenically- or pharmacologically-acquired aphantasia (e.g., post-SSRI, post-trauma), the clinical literature gives little guidance, but the underlying mechanism is presumably more reversible than congenital cases — and at least the network targets are now known.

11. Recovered cases — congenital aphantasia → typical imagery

Two routes have produced documented "recovery" of sorts:

Single-dose psychedelic experiences — see section 5. The pre-print case of the woman with mushrooms going from VVIQ 16 to a sustained, year-later "average" score is the strongest single example.
Trauma reprocessing — some EMDR and hypnotherapy practitioners have reported clients gaining glimpses of imagery during deep reprocessing of early trauma. This raises the de Vito/Bartolomeo question of whether some "congenital" aphantasia is actually dissociative or defensive in origin. There are no controlled studies, just clinical reports.

Beyond these, the published literature does not contain clean cases of congenital aphantasics who, through training alone, transitioned to typical imagery and held that gain longitudinally. Forum reports of such transitions exist but are unverifiable and could reflect demand effects, recalibration of self-report, or genuine but rare cases.

12. Compensatory strategies — what aphantasics actually use

This is the most well-supported area. Aphantasics navigate the world using:

Verbal/semantic encoding: Storing memories, plans, and information as language and propositions rather than pictures. Aphantasics often have strong verbal working memory and conceptual fluency.
Spatial reasoning: Spatial cognition is generally intact in aphantasia (spatial imagery is dissociable from object imagery). Many aphantasics navigate, do mental rotation, and reason about space without visual pictures — they "know where" rather than "see where."
External offloading: Lists, mind-maps, sticky notes, photos, sketches, calendars, repeated drawing-from-reference. Aphantasics show heavy reliance on environmental scaffolding.
Motor and sensorimotor strategies: Embodied anchoring — walking through a problem, gesturing while thinking, physically rehearsing rather than mentally rehearsing.
Anchoring novel info to familiar references: "It's like X but with Y" rather than building a fresh mental picture.
Multi-modal encoding: Sound, smell, and emotional tone often substitute for or complement what visualizers do with pictures.

A 2025 paper ("Unseen strategies", Bainbridge and colleagues; and Monzel et al.) identifies semantic reliance, condensation of inner speech, and external recoding as three principal compensatory mechanisms. Cognitive performance on standardized measures is generally normal, suggesting these strategies are highly effective — they're a different cognitive route to similar destinations, not a reduced one.

13. Therapy implications: CBT, exposure, EMDR

This is where the practical stakes are highest, since trauma therapies often assume imagery as a core mechanism.

CBT: Standard cognitive-behavioral protocols often use imaginal exposure and "thought experiments" that involve picturing scenarios. Aphantasics can usually do the verbal/conceptual versions of these exercises (describe the feared outcome, articulate the cognitive distortion) without the visual component. Outcome data specific to aphantasic CBT clients is sparse. Anecdotally, aphantasics report that CBT works "from the language side."

Imaginal exposure and exposure therapy: Traditional imaginal exposure for PTSD and phobia relies on visualizing the feared stimulus. Aphantasics may need in vivo exposure (real stimuli), virtual reality (which provides the visual input externally), or affect-driven approaches that rely on emotional reactivation rather than visual reactivation.

EMDR: EMDR's standard protocol asks the client to "bring up the worst image" of the trauma. Aphantasic clients can't. Adaptations include focusing on the felt sense (somatic activation), the emotional tone, the narrative of the memory, or auditory/olfactory traces. The EMDR community has begun to publish on this (EMDRIA Counselor's Corner pieces, the EMDR Doctor podcast). Anecdotally, EMDR can still be effective for aphantasic clients when adapted, and some clients have reported transient imagery emerging during reprocessing — but rigorous comparative outcome data does not yet exist.

Practical caution: Survey data shows only ~3% of aphantasic clients felt their mental health professional understood the condition. Bringing this up explicitly with a therapist, and asking about somatic/affect-based or third-wave (ACT, mindfulness) alternatives, is reasonable.

Possible upside: Early observations suggested aphantasics might be partially protected from PTSD because they don't get visual flashbacks. More recent research has tempered this — PTSD prevalence in aphantasics appears comparable to the general population, just with the symptom profile shifted away from visual intrusions toward somatic, emotional, or narrative re-experiencing.

14. Honest assessment: what works, what's snake oil, what's untested

Reasonable evidence (still limited): - Functional Imagery Training and other multisensory imagery programs from sport psychology: a real RCT with maintained gains, though on a self-report measure, in low imagers including some aphantasics. - Compensatory strategies (verbal, spatial, external offloading): well-established, the actual basis of how aphantasics function effectively. - Therapy adaptation (somatic-focused EMDR, verbal CBT, ACT): clinically reasonable, growing literature.

Promising case reports, not yet validated: - Psychedelics (ayahuasca, psilocybin): two published-or-pre-printed case reports of durable imagery induction; serious ethical concerns about irreversibility and mental-health risk; no controlled trial. - Hypnosis / phenomenological control framing: theoretically interesting, weakly supported, useful as a therapeutic adjunct rather than an imagery-induction protocol. - tDCS of visual cortex: mechanistically plausible based on non-aphantasic data; unstudied in aphantasics.

Marketed but largely unsupported: - Image Streaming (Win Wenger): popular, mechanistically possible, but the IQ/imagery claims are not backed by controlled studies. Mixed anecdotal results. Low downside if you find the practice tolerable; don't expect dramatic change. - "Visualize a red apple" generic advice: zero evidence in aphantasics; risk of frustration and reinforced helplessness.

Probably-snake-oil: - Vision therapy / orthoptics for aphantasia: addresses the wrong system entirely. - Hypnosis training programs that promise to "cure" aphantasia in N sessions: the underlying technique may be useful as adjunct; the cure framing is unsupported. - DIY brain-stimulation kits sold for visualization improvement: extrapolating from one non-aphantasic study is not a basis for self-electrocution. - IQ-boost claims attached to any of the above: ignore.

Genuinely untested: - Long-term meditation / contemplative visualization practice in aphantasics - Pharmacological agents other than psychedelics - VR-based imagery training (mentioned as a research direction but not yet trialed in aphantasic samples) - Combined protocols (e.g., FIT + tDCS, or hypnosis + structured imagery practice)

15. What this means for someone with aphantasia

If your goal is to function well as an aphantasic, the evidence overwhelmingly points to leaning into compensatory strategies — they work, they're free, and other aphantasics have built rich lives on them.

If your goal is to test whether you can develop imagery, the most defensible starting points are: (1) structured, multisensory imagery training along FIT lines, with objective benchmarking (VVIQ, ideally a binocular-rivalry test); (2) sustained, low-pressure meditation with attention to faint sensory traces rather than expectation of full pictures; and (3) honest tracking over months, not days. Avoid programs that promise a cure.

If you're considering psychedelics as an imagery-induction route, recognize you are running an n=1 experiment based on two case reports, accepting non-trivial mental-health and legal risks, and may not be able to undo the change you induce. The published researchers most expert in this space (Pearson, the Cortex 2025 group) are explicitly cautious, not enthusiastic.

If you're in therapy, advocate for adapted protocols. The available data suggest CBT, EMDR, and exposure therapy can all be effective for aphantasic clients when delivered by clinicians who understand the condition and don't insist on visualization-dependent techniques.
