If you see a ghost of something that’s no longer there — a car’s taillights streaking across your vision, a face hovering after you’ve looked away — those could be signs of palinopsia. It’s a neurological visual symptom, not an eye problem, and it’s more common in people with migraine than most people realize.
What Is Palinopsia, Exactly?
The name comes from the Greek words palin (“again”) and opsia (“seeing”). Palinopsia is when a visual image persists or reappears after the object causing it is gone. This isn’t the same as the momentary afterimage you get from staring at a bright light — that’s a normal physiological response. Palinopsia is something else: longer-lasting, sometimes vivid, and often disorienting.
It’s classified as a neuro-ophthalmic symptom, meaning it originates in how the brain processes visual information, not in the eye itself. Palinopsia falls into two categories — illusory and hallucinatory.
A 2022 review published in Practical Neurology noted that palinopsia is an important but underrecognized condition that can be misdiagnosed as migraine or a functional disorder — meaning it also gets missed when it is part of a migraine picture.
For people with migraine, palinopsia tends to be on the illusory side, tied to shifts in how the visual cortex fires during and after attacks. Research suggests it may affect up to 10% of people with migraines, and appears more frequently in those who have migraine with aura than those without.
The Two Types of Palinopsia — and Why the Difference Matters
Before going through the specific signs, it helps to know which type you might be dealing with. The two types have different causes, different appearances, and different implications.
Illusory Palinopsia
This is the type most closely associated with migraine. The afterimages are low-resolution, unformed, or blurry. They’re short-lived — usually a few seconds. They tend to occur in the same location in your visual field as the original object, and they’re highly influenced by environmental factors: bright light, contrast, or movement make them worse.
Think: smeared light trails, a faint echo of a moving object, or a color wash lingering where someone was sitting.
Hallucinatory Palinopsia
This type is less common in migraine and more associated with structural brain lesions, seizures, or certain medications. The afterimages are vivid, high-resolution, and lifelike — almost like a photographic replay. They can appear anywhere in the visual field, not just where the original stimulus was, and they don’t depend on lighting conditions. A scene or a face might reappear in full color, seemingly out of nowhere.
Anyone who experiences even a single episode of hallucinatory palinopsia should be evaluated by a neurologist or neuro-ophthalmologist, and an MRI should be considered.
Signs of Palinopsia: What You Might Be Experiencing
Here are the most common and recognizable signs, particularly as they present in people with migraine.
1. Afterimages That Linger Too Long
A normal physiological afterimage fades within a second or two. With palinopsia, afterimages stick around — sometimes for several seconds, sometimes longer. They may be the same color as the original object, or they may appear in a complementary or inverted color.
The key difference is that a normal afterimage is predictable and fades quickly. A palinoptic afterimage lingers in a way that feels wrong, and it may happen after looking at everyday objects, not just bright lights.
2. Visual Trailing (Trailing Phenomenon)
This is one of the most frequently reported signs, especially in migraine-related palinopsia. When an object moves — a hand waving, a car passing, someone walking — it leaves a trail of copies behind it, like a film reel or a long-exposure photograph.
Those copies may appear as a smooth blur or as a series of distinct, stacked frames. Either way, the moving object looks like it’s leaving frozen echoes in its wake. A 2024 study from the University of Melbourne examining palinopsia in visual snow syndrome found that trailing and unformed afterimages were among the most commonly reported presentations.
Some people also notice trailing when they move their own eyes or head rather than the object itself.
3. Light Streaking
Bright light sources against a dark background are especially prone to triggering this sign. Streetlights, car headlights, phone screens in a dark room — these may appear to stretch or smear into long streaks, as though the image is being dragged across your field of vision.
This is one reason people with palinopsia may report difficulty with night driving, where oncoming headlights produce multiple overlapping streaks that can obscure vision.
If you’ve ever found yourself gripping the steering wheel a little tighter at night because the lights feel like they’re “bleeding,” this could be a sign worth mentioning to your neurologist.
4. Stacking or Overlapping Images
Sometimes the afterimages of multiple things pile up, making it difficult to visually separate what’s in front of you now versus what you were looking at a moment ago. Instead of seeing one clear object, you see several layered versions of recent visual information simultaneously.
This stacking effect can be particularly disorienting in busy visual environments — scrolling through a phone, watching television, or walking through a crowded space.
5. Images That Replay Like a Loop
In hallucinatory palinopsia, a scene or action — not just a static image — can replay itself. Someone might look up from a book and see the last few seconds of a video they were watching replaying in their field of vision. Or the last face they looked at might appear, in full detail, somewhere in the room.
This is distinct from the illusory type. These images are formed and detailed, not blurry or faint. If this is what you’re experiencing, it needs prompt evaluation.
6. Increased Symptoms in Bright or High-Contrast Environments
In illusory palinopsia, symptom intensity varies with the visual environment. High-contrast settings — a bright window in a dark room, sunlight off a white wall, a backlit screen — tend to make afterimages more pronounced and longer-lasting.
Similarly, environments with high movement can trigger or worsen trailing. A busy restaurant, a crowded street, or even a fast-paced movie may feel visually overwhelming in ways that have a concrete physical component, not just anxiety.
7. Visual Disturbances That Persist After a Migraine
Most migraine aura symptoms — the classic shimmering zigzag, the blind spot, the pins-and-needles — resolve within an hour, usually before or as the headache begins. Palinopsia that lingers after the migraine has passed, or that seems disconnected from any specific attack, is worth tracking and reporting.
A rare migraine subtype called persistent visual aura without infarction (also called persistent migraine aura, or PMA) can produce ongoing illusory palinopsia symptoms — including prolonged afterimages, light streaking, and trailing — that don’t resolve after the migraine ends. In this subtype, these symptoms can persist long after an attack has abated.
This is different from ordinary aura and needs its own evaluation.
8. Symptoms That Overlap with Visual Snow
Many people who experience palinopsia also report visual snow — a persistent static over their entire visual field, as though they’re looking through a slightly snowy television screen. The two are closely linked.
A 2024 study published in Investigative Ophthalmology & Visual Science found palinopsia to be a common but poorly understood symptom in visual snow syndrome and that participants with visual snow syndrome exhibited different patterns of temporal visual processing compared to controls. Visual snow syndrome itself has well-established connections to migraine, particularly migraine with aura.
9. Symptoms That Worsen with Fixation
One specific sign of illusory palinopsia: afterimages that become more intense the longer you fix your gaze on something. Staring at a face, a logo, or a bright object, then looking away, may produce an unusually vivid or long-lasting impression.
This is different from the hallucinatory type, where images can appear unpredictably. Illusory palinopsia is more predictable — it follows fixation, light intensity, and contrast — which is one of the features that helps clinicians distinguish between the two types.
10. Difficulty Distinguishing Palinopsia from Normal Afterimages
This one is more of a meta-sign: many people with palinopsia initially dismiss what they’re seeing as normal. A quick flash-photo afterimage is normal. But if you’re regularly noticing that images linger after ordinary visual tasks — reading, looking at a screen, watching people move — and this feels unusual compared to what you used to experience, that sense that something has changed is itself meaningful.
What Causes Palinopsia in People with Migraine?
The working theory is cortical hyperexcitability — the same underlying dysfunction that drives migraine aura. During a migraine, a wave of electrical activity called cortical spreading depression moves across the visual cortex. This disrupts normal visual processing, and in some people, the disruption affects how long the brain “holds onto” visual signals.
Illusory palinopsia is thought to result from changes in neuronal excitability in the visual pathways — specifically shifts in neurotransmitter receptor activity, particularly involving the serotonin system (5-HT2 receptors). This is also why certain medications that affect serotonin (trazodone, mirtazapine, risperidone) have been associated with palinopsia as a side effect.
A 2023 review published in Neurología examining visual snow syndrome and its relationship with migraine found that people with migraine had a higher prevalence of the condition, reinforcing the overlap between migraine neurology and persistent visual disturbances like palinopsia.
The short version: migraine doesn’t just cause head pain. It changes how the brain processes everything — including, for some people, how long visual images stick around.
Palinopsia vs. Normal Afterimages: A Quick Comparison
It can be genuinely confusing to know what’s “normal” and what isn’t. Here’s a simple way to think about it:
Normal physiological afterimage:
- Happens after staring at a bright or high-contrast image for several seconds
- Fades within 1–2 seconds of looking away
- Usually appears in a complementary color (look at red, see green)
- Predictable and not distressing
Palinopsia:
- Happens after ordinary visual tasks, not just prolonged staring
- Lasts longer than a couple of seconds — sometimes much longer
- May be the same color or brightness as the original
- Can happen unpredictably, outside of obvious triggers
- May include trailing, stacking, or replay effects, not just a static ghost image
If what you’re experiencing aligns more with the second column than the first, bring it up with your care team.
When to Seek Medical Attention
For migraine patients, palinopsia-like symptoms often come and go with attacks and may feel like “just another weird aura thing.” But there are circumstances where you should seek evaluation promptly:
- Palinopsia appears for the first time without a migraine history. New visual symptoms without a clear cause need evaluation.
- You’re experiencing hallucinatory palinopsia — vivid, detailed, lifelike images replaying or appearing in your visual field.
- Symptoms are worsening or becoming more frequent. Escalating palinopsia in someone with migraine can indicate a change in how the condition is progressing.
- Palinopsia persists between migraines or long after an attack. This may suggest persistent migraine aura or another underlying issue.
- You have other new neurological symptoms — weakness, speech changes, severe sudden headache — alongside visual disturbances. This combination is a medical emergency.
When in doubt about any new visual symptom, seek evaluation. Some causes of palinopsia can indicate structural brain changes that are both serious and treatable.
Tracking Your Symptoms
If you suspect you’re experiencing palinopsia, keeping a log before your next appointment can be incredibly useful. Note:
- When it happens — during a migraine, after one, or independently
- What triggers or worsens it — bright light, movement, high-contrast environments, screens
- What type of visual effect — trailing, persistent afterimages, light streaking, image replay
- How long it lasts — seconds, minutes, or longer
- Whether it’s in both eyes or one — closing each eye alternately can help figure this out
- Any medications you’ve recently started or changed — some drugs are known to cause or worsen palinopsia
