There is no proven cure for aphantasia. The condition, which affects roughly 1% of the population, is considered a natural variation in how brains process imagery rather than a disease or disorder. Most people with aphantasia have never been able to visualize, and researchers note they manage well in everyday life. That said, a small but growing body of research points to techniques and interventions that may strengthen or even activate mental imagery in some people.
Why Aphantasia Is Hard to “Cure”
Aphantasia was only named in 2015, and the neuroscience is still catching up. Two recent studies have provided the first direct evidence linking activity in the primary visual cortex to imagery deficits in aphantasia, but researchers describe the neural underpinnings as “poorly understood.” The brain’s visual cortex is active when you see the real world and when you picture something in your mind. In people with aphantasia, that second pathway doesn’t fire the same way, but no one yet knows exactly why or how to reliably change it.
This matters because without a clear mechanism, there’s no clear target for treatment. Most aphantasia is congenital, meaning it’s been present from birth. The brain didn’t lose a function; it simply developed without one. That’s a fundamentally different challenge than restoring something that was lost.
Acquired Aphantasia: Recovery Is Sometimes Possible
A small number of people develop aphantasia after brain injury, surgery, or illness. In these cases, partial recovery has been documented. One published case involved a patient who lost all mental imagery on day 9 of treatment for a blood cancer. He scored the lowest possible score (16 out of 80) on a standard imagery vividness questionnaire. By his six-month follow-up, his score had improved to 23, reflecting mild improvement but not a return to normal visualization.
If you once had vivid mental imagery and lost it, there’s reason to believe the underlying neural pathways still exist. Recovery tends to be slow and incomplete based on the limited case reports available, but it does happen. Working with a neurologist or neuropsychologist makes sense in these situations.
Image Streaming: The Most Popular Exercise
The technique most commonly recommended in aphantasia communities is called image streaming. The process works like this: you look at a room or scene with your eyes open and describe every visual detail out loud in as much detail as possible. You repeat this several times. Then you close your eyes and try to recreate the scene from memory, continuing to describe it verbally.
The idea is that by forcing your brain to put visual details into words repeatedly, you build a stronger connection between language processing and visual processing areas. Proponents report that over weeks or months of daily practice, faint imagery begins to emerge.
The important caveat: this technique has not been studied scientifically. The APA has acknowledged the emerging trend but notes the absence of controlled research. Anecdotal reports vary widely. Some people describe breakthrough moments after weeks of practice, while others report no change after months. Without data, it’s impossible to say what percentage of people benefit or whether the perceived changes reflect genuine imagery versus other cognitive shifts like improved spatial reasoning.
Brain Stimulation Research
One of the more intriguing findings comes from research on transcranial direct current stimulation (tDCS), a technique that uses mild electrical currents applied to the scalp to increase or decrease activity in specific brain regions. A study published in eLife found that decreasing excitability in the visual cortex actually increased imagery strength in participants, while increasing excitability in the prefrontal cortex (the area behind your forehead involved in higher-level thinking) also boosted imagery. The effects were statistically significant and couldn’t be explained by practice effects alone.
This is a proof of concept, not a treatment. The study involved 16 participants with typical imagery, not people with aphantasia specifically. And the effects were measured during a single session, so we don’t know if they persist. Combining stimulation of both brain areas at once didn’t produce reliable results, which highlights how complex the imagery network is. Still, this line of research suggests that imagery strength is something the brain can be nudged on, at least temporarily.
Psychedelics: A Single Remarkable Case
One widely discussed case report describes a 34-year-old woman who had lifelong aphantasia and experienced vivid mental imagery for the first time after consuming psilocybin truffles. Her imagery vividness score jumped from 16 (the absolute minimum) to 80 (the maximum) immediately after. At 12 months, her score had settled to 59. At 33 months, it had risen slightly to 68, which is above the population average.
She reported dreaming in images for the first time in her life. Over time, some abilities faded. By the 12-month mark, her mental images had shifted from full color to shades of gray, and she could no longer easily imagine animated scenes, though she could still picture static images like a photograph. Nearly three years later, the ability persisted.
This is a single case report, not a clinical trial. It’s impossible to draw conclusions about whether psilocybin would work for others, what dose matters, or what risks are involved. Psilocybin remains a controlled substance in most jurisdictions. But the case is notable because it demonstrates that a brain wired for lifelong aphantasia can, under certain conditions, begin generating imagery, and that the change can last years.
Practical Approaches People Try
Beyond image streaming, people in aphantasia communities experiment with several other techniques. None have scientific backing, but they’re worth understanding if you’re exploring your options.
- Afterimage exercises: Staring at a bright light source briefly, then closing your eyes to observe the residual shape (called a phosphene or afterimage). The goal is to give your brain something concrete to “see” internally and build from there. Results are mixed, and some people with aphantasia report they can see afterimages while others cannot.
- Memory-based description practice: Similar to image streaming but focused specifically on recalling familiar places or faces and describing them in exhaustive detail, trying to “push” the brain toward generating a visual component alongside the verbal description.
- Meditation and hypnagogic states: Some people report faint imagery in the moments just before falling asleep, even if they experience none during waking hours. Practicing awareness during this transition state is sometimes suggested as a way to train the brain to produce imagery more deliberately.
What Success Actually Looks Like
Among the small number of people who report improvement, the outcome is rarely a switch from total darkness to high-definition mental movies. More commonly, people describe faint, fleeting flashes that gradually become slightly more stable or detailed over months. Some people develop the ability to “sense” shapes or spatial relationships without truly seeing them, which may represent a form of non-visual imagery rather than the visual kind most people mean when they talk about “picturing” something.
It’s also worth considering that aphantasia exists on a spectrum. About 3.3% of people have hypophantasia, meaning dim or vague imagery that falls short of typical vividness. If you’re closer to that end of the spectrum, you may find exercises more productive than someone with complete aphantasia. The roughly 0.9% of people who score at the absolute bottom of imagery assessments face a steeper challenge.
For now, aphantasia is best understood as a trait rather than a condition to be fixed. Many people with aphantasia lead rich creative and professional lives, including as artists, architects, and writers, using spatial reasoning, conceptual thinking, and verbal strategies where others use visual imagery. If you want to explore exercises like image streaming, the investment is low risk. But if nothing changes, that isn’t a failure. Your brain simply works differently.
