Palinopsia

Palinopsia means you keep seeing an image after the real object is gone. The picture may linger in place, follow or “trail” moving things, or pop back into view a few seconds later. Palinopsia is a symptom, not a disease. It happens when the brain’s visual system becomes overly excitable or disrupted. Causes range from migraine and seizures to side effects of medicines, recreational drugs, and (rarely) serious problems in the back part of the brain. Treatment focuses on finding and fixing the cause, easing triggers, and calming the visual system. EyeWikiPubMedCleveland Clinic

Palinopsia means “seeing again.” You might see a positive afterimage (same color and brightness as the original thing), a ghosted duplicate, light streaks, or trails behind moving objects. These images usually fade within seconds but can last longer. Palinopsia is different from normal afterimages you get after staring at something bright; in palinopsia the effect is stronger, more frequent, not tied only to bright lights, and often happens with other visual symptoms (like light sensitivity or “visual snow”).

Palinopsia means that a picture you just saw lingers or comes back in your vision after the real thing is gone. You might still see the face of a person after they walk away, or see “trails” behind a moving car or hand. These extra images can be brief (seconds) or longer (minutes). They can look sharp and detailed or fuzzy and faint. Palinopsia is not the same as a normal afterimage that almost everyone gets after staring at a bright light; in palinopsia, the images are stronger, more frequent, more disturbing, and not limited to bright lights.

Doctors group palinopsia into two big types based on how the extra image looks and what tends to trigger it:

• Illusory palinopsia: the extra images are usually faint, short-lived, or low detail. They are often worse with bright light, high contrast, motion, or long staring. Common examples are “trailing” behind moving objects or light streaks from headlamps at night. Illusory palinopsia often comes from changes in the way the brain processes vision (for example during migraine, with certain medicines, or after using hallucinogenic drugs). PubMedScienceDirectEyeWiki

• Hallucinatory palinopsia: the extra images are clear, formed, and detailed (for example, a full face or a whole object) and they do not depend much on light, contrast, or movement. This type is more likely when there is a problem in the back part of the brain (the visual cortex), such as a seizure, stroke, or a mass. PubMedScienceDirect

Thinking in this two-type way helps doctors choose the right tests and look for the right causes.

Clinicians group palinopsia into two types:

• Illusory palinopsia: afterimages are vague/low-resolution, change with lighting and motion; often linked to migraine, medications, head injury, visual snow syndrome (VSS), or hallucinogen-persisting perception disorder (HPPD).

• Hallucinatory palinopsia: formed, high-resolution images that can last longer; more often linked to seizures or lesions in the back of the brain (occipital/posterior cortex). ScienceDirectCleveland Clinic

Types

1. Illusory palinopsia
   You see short, faint, or smeared afterimages. You may notice light streaks, ghosting, or trails following moving objects. Bright light, high contrast (black letters on white paper), long staring, or fast motion make it worse. This is common with migraine, visual snow, some medicines, and hallucinogen persisting perception disorder (HPPD). EyeWiki+1Frontiers

2. Hallucinatory palinopsia
   You see clear, formed, and detailed images. The image can reappear in a different place or be layered on the background you are looking at. Light and motion do not change it much. This type is a red flag for seizures, strokes, or structural problems in the visual parts of the brain. PubMed

Causes

Important: one person can have more than one cause. For example, a person with migraine who also takes a medicine linked with palinopsia may be at higher risk.

1. Migraine (with or without aura)
   During and between migraines, the visual system becomes over-excitable. This can cause trailing and afterimages, especially in bright or high-contrast settings. Illusory palinopsia is common here. PubMedScienceDirect

2. Visual Snow Syndrome
   People with visual snow often report palinopsia, especially trailing and afterimages, because the brain’s visual network handles signals differently all the time, not just during headaches. Frontiers

3. Occipital lobe seizures (epilepsy at the back of the brain)
   Seizures that start in the visual cortex can create sudden, recurrent visual images, sometimes with other visual effects. This is more often the hallucinatory type. ScienceDirectPubMed

4. Stroke in the posterior brain (especially PCA territory)
   A lack of blood flow to the visual cortex can produce palinopsia, sometimes as a sudden new symptom that needs urgent care. NCBI

5. Brain tumors or masses in the occipital/temporo-occipital area
   Growths that affect visual processing areas (like gliomas) can cause formed images to reappear or linger. PMC

6. Cerebral amyloid angiopathy–related inflammation (CAA-RI)
   This inflammatory brain vessel disease in older adults can first show up with palinopsia and other visual changes. PMC

7. Severe low blood sugar (hypoglycemia) with brain injury
   After a hypoglycemic coma, some people develop complex visual problems, including hallucinatory palinopsia. www.elsevier.com

8. Head injury or concussion
   A blow to the head can irritate visual pathways, leading to ghosting and trailing, especially in busy visual scenes. (Illusory type is most common.)

9. Posterior reversible encephalopathy syndrome (PRES)
   Rapid blood-pressure swings and brain swelling in the back of the brain can disturb vision and sometimes cause palinopsia.

10. Hallucinogen Persisting Perception Disorder (HPPD)
    After using hallucinogens (such as LSD), some people develop lasting visual symptoms. Trails and afterimages are classic in HPPD. EyeWiki

11. Cannabis and other recreational drugs
    Some people notice palinopsia during or after use, especially if they already have migraine or anxiety (often overlaps with HPPD-like changes).

12. Trazodone and related antidepressants (5-HT2 antagonists)
    Trazodone can cause palinopsia even without other brain disease. Similar reports exist with nefazodone, mirtazapine, and risperidone. (If this is the cause, stopping or switching often helps.) JAMA NetworkEyeWiki

13. Topiramate
    This seizure/migraine medicine can trigger palinopsia in some patients; symptoms often ease after dose reduction or stopping. PubMed

14. Zonisamide
    Another anti-seizure/migraine drug that has been linked to palinopsia in case reports. PubMed

15. Clomiphene citrate (fertility medicine)
    Short courses have caused transient palinopsia in published cases; symptoms resolved after the drug was stopped. PubMed

16. Other medicines
    Some antipsychotics and antidepressants that act on serotonin receptors may trigger illusory palinopsia in sensitive people. EyeWiki

17. Occipital arteriovenous malformations or cavernous angiomas
    Abnormal blood vessels near the visual cortex can irritate the area and lead to palinopsia or other visual repeats. (Hallucinatory type is more likely.)

18. Inflammatory or demyelinating brain diseases
    Conditions that inflame or strip myelin from the visual cortex and pathways can create persistent or recurrent images.

19. Toxic-metabolic states (severe electrolyte or liver problems)
    Rarely, global brain stress changes visual processing and may present with palinopsia-like afterimages.

20. Idiopathic (no clear cause found)
    Even after full testing, some people have palinopsia without a definite cause. In these cases, symptoms may fluctuate and sometimes improve over time.

Symptoms

1. Afterimages that last longer than normal
   You keep seeing an object after you look away, even if you did not stare at anything bright.

2. Trailing behind moving objects
   When a hand or car moves, you see several faded copies following behind it, like a slow-motion echo.

3. Light streaking or smearing
   Headlights or phone screens leave long streaks or smears that linger as you move your eyes.

4. Ghosting or double edges
   Letters and shapes have shadow edges or ghost copies, making reading hard.

5. Formed repeats
   You might briefly see a clear face or object reappear somewhere else, even though it is gone (more typical of hallucinatory palinopsia).

6. Worse with bright light or high contrast
   White paper with black print, sunlight, and glossy screens make it much worse (classic for the illusory type).

7. Worse with motion or long staring
   Watching fans, scrolling text, or moving traffic can trigger trails or stuttering images.

8. Better in dim light
   Some people feel relief in lower light or with tinted lenses.

9. Headache or migraine
   Palinopsia can occur during a migraine or between attacks; light sensitivity is common too.

10. Visual snow or static
    Many patients describe tiny moving dots across the whole view, together with palinopsia. Frontiers

11. Anxiety or panic about the visuals
    Strange visual repeats can be scary; worry can then amplify the symptoms.

12. Night driving trouble
    Streaks and afterimages from headlights make it hard to judge distance or speed.

13. Reading fatigue
    Ghosting and trailing over lines of text cause eye strain, slow reading, and loss of place.

14. Brief visual spells
    If seizures are the cause, episodes can be sudden, repetitive, and may include other visual distortions.

15. Field gaps or blind spots
    When a stroke or lesion is present, there may be missing areas in vision along with palinopsia.

Diagnostic tests

The goal of testing is to (1) confirm the symptom pattern, (2) check the eyes and the brain, and (3) find a treatable cause. Not everyone needs every test—your history and exam guide the choices.

A) Physical examination

1. Full neurologic exam (especially cranial nerves and visual pathways)
   The doctor checks eye movements, facial strength, sensation, balance, and thinking. This looks for signs of stroke, seizures, or brain irritation in the visual system.

2. Visual acuity (eye-chart) test
   Basic clarity testing (like 20/20) helps separate palinopsia from eye-surface or lens problems that blur vision.

3. Pupil exam and light response
   The doctor checks how your pupils react to light to spot optic-nerve or retina issues that might be part of the picture.

4. Dilated fundus exam
   Looking at the retina and optic nerve can rule out macular disease, optic swelling, or bleeding that could complicate symptoms.

B) Manual/bedside vision tests

5. Confrontation visual fields
   You cover one eye while the clinician checks the edges of your vision. Field gaps suggest a brain-side problem (like stroke) and push toward brain imaging.

6. Amsler grid
   This simple grid shows waviness or missing spots that point to macular or cortical processing issues.

7. Color vision testing (Ishihara plates)
   Color loss can hint at optic-nerve trouble rather than pure cortical afterimages.

8. Red desaturation test
   If a red object looks washed-out in one eye, it suggests optic-nerve involvement.

9. Photostress recovery test
   You stare at a bright light briefly; the time your vision takes to recover can separate macular from nerve/brain causes.

C) Laboratory / pathological tests

10. Basic labs and metabolic panel (including glucose and electrolytes)
    Severe blood sugar drops, electrolyte issues, or liver/kidney problems can worsen brain function and visual processing.

11. Thyroid function tests
    Thyroid problems can add to migraine and visual sensitivity, so doctors often screen for them.

12. Vitamin B12 and folate
    These check for nutritional nerve problems that can muddy the picture.

13. Toxicology screen and medication review
    This looks for hallucinogens and checks medicines known to trigger palinopsia, such as trazodone or topiramate. Finding a drug cause can change treatment right away. JAMA NetworkPubMed

D) Electrodiagnostic tests

14. EEG (electroencephalogram)
    Scalp leads record brain waves. Occipital spikes or abnormal rhythms support seizures as the cause of palinopsia. ScienceDirect

15. Visual evoked potentials (VEP)
    This test measures the brain’s response to patterned images. Slowed or asymmetric signals suggest a pathway problem from the eye to the visual cortex.

16. Electroretinography (ERG)
    This checks the retina’s electrical responses. It helps rule out retinal disease when symptoms are tricky.

E) Imaging tests

17. MRI of the brain with and without contrast (focus on occipital and parietal lobes)
    This is the main scan to look for strokes, inflammation, tumors, or scarring where vision is processed. Diffusion-weighted images help catch acute stroke. NCBI

18. CT head (especially if symptoms are sudden)
    A fast scan to spot bleeding or large strokes when urgent decisions are needed.

19. MRA or MRV (artery and vein imaging of the head/neck)
    These scans look for vessel blockages, clots, or malformations that can affect the visual cortex.

20. Optical coherence tomography (OCT) of retina and optic nerve
    OCT takes high-resolution pictures of the retina and nerve to rule out eye-based causes and document baseline status.

Non-pharmacological treatments (therapies & practical steps)

1. Identify and stop the culprit medicine (with your prescriber). This is often the fastest fix when a new drug started before symptoms. Purpose/Mechanism: removes a trigger that raises cortical excitability. Cleveland Clinic

2. Absolute avoidance of hallucinogens/recreational stimulants. Purpose: prevent HPPD and symptom flares. Mechanism: avoids persistent serotonin/visual-cortex dysregulation. PMC

3. FL-41 precision-tinted lenses (or individually selected tints). Purpose: reduce visual stress, glare, and afterimages. Mechanism: filters wavelengths that provoke cortical hyperexcitability and photophobia. Evidence suggests consistent symptom relief for VSS-related palinopsia. PMC+1

4. Lighting hygiene. Use diffuse, steady light; avoid flicker; reduce extreme contrast; use desk lamps shining onto the wall/surface (not at eyes). Mechanism: reduces abrupt luminance changes that drive afterimages.

5. Screen optimization. Increase refresh rate, reduce brightness, enlarge font, use dark mode or sepia, add matte/anti-glare filters, take micro-breaks (20-20-20 rule). Mechanism: lowers retinal/visual-cortex load. Ophthalmology Times

6. CBT (cognitive behavioral therapy) or anxiety-focused therapy. Purpose: reduce hypervigilance and distress, which amplify symptom salience. Mechanism: retrains attention and threat appraisal; promising data in VSS. PMC

7. Migraine lifestyle program. Regular sleep, hydration, meals; limit caffeine/alcohol; steady exercise. Mechanism: stabilizes cortical excitability thresholds.

8. Headache trigger diary. Note lighting, screens, stress, sleep debt, foods—then adjust. Mechanism: behavioral feedback loop to reduce exposures.

9. Mindfulness/relaxation training. Breathwork, guided imagery, progressive muscle relaxation. Mechanism: down-regulates limbic arousal that worsens visual symptoms.

10. Vision/occupational therapy consult (especially after concussion). Purpose: task-specific strategies, environmental tweaks, pacing.

11. Sunglasses strategy. Use moderately tinted lenses outdoors; avoid deep, very dark lenses indoors (can increase dark adaptation and sensitivity later). Mechanism: right amount of filtering without over-darkening.

12. Sleep restoration plan. Set wind-down routine, consistent hours, manage blue-light exposure before bed. Mechanism: normalizes cortical excitability and pain thresholds.

13. Safety adjustments. Avoid night driving until stable; choose safer routes/lighting.

14. Treat coexisting eye problems (dry eye, uncorrected astigmatism) to minimize optical ghosting that confuses the picture.

15. Gradual visual exposure (don’t avoid everything): brief, controlled exposure to common triggers to retrain tolerance.

16. Hydration + regular meals. Prevents glucose swings that can worsen brain irritability.

17. Posture/ergonomic setup for screen work (distance, height) to cut glare and strain.

18. Blue-green filtering on devices (software filters). Mechanism: shifts spectral input away from provocative bands for some patients.

19. Psychoeducation & reassurance. Understanding reduces anxiety, which often reduces symptom intensity.

20. Follow-up monitoring. Adjust the plan as triggers change.

Drug treatments

There is no single “cure pill” for palinopsia. Medicines are chosen to treat the cause (e.g., migraine, seizures, HPPD) or to calm cortical hyperexcitability. Evidence is mostly case series/observational; discuss risks–benefits with your doctor.

1. Lamotrigine (antiepileptic/mood stabilizer).

   • Typical dose: start 25 mg daily and slowly titrate (e.g., 100–200 mg/day).

   • Purpose/Mechanism: dampens cortical hyperexcitability; best documented for VSS/HPPD-type palinopsia.

   • When to take: divided doses; titrate over weeks to lower rash risk.

   • Side effects: dizziness, nausea, insomnia; rare serious rash (SJS) → urgent care.

   • Evidence: partial improvement in a subset of VSS patients; case reports in HPPD. American Academy of NeurologyPMC+1

2. Clonazepam (benzodiazepine).

   • Dose: 0.25–1 mg at night or BID (lowest effective; short term).

   • Purpose: reduces visual “trails” and anxiety in HPPD/VSS.

   • Mechanism: enhances GABA inhibition.

   • Side effects: sedation, falls, dependence; taper if stopping. PMCBrain Stimulation Journal

3. Levetiracetam (antiepileptic).

   • Dose: 500–1,500 mg twice daily.

   • Use: occipital seizures or highly excitable cortex; some clinicians trial in refractory VSS/palinopsia.

   • Side effects: mood/irritability, fatigue.

4. Valproate (divalproex) (antiepileptic/migraine preventive).

   • Dose: 250–500 mg twice daily (titrate per levels).

   • Use: occipital seizures/migraine biology.

   • Cautions: teratogenic, weight gain, liver issues.

5. Carbamazepine (antiepileptic).

   • Dose: 200–400 mg twice daily.

   • Use: focal (occipital) seizures that present with palinopsia.

   • Side effects: dizziness, low sodium; drug interactions.

6. Propranolol (beta-blocker).

   • Dose: 20–80 mg twice daily (or LA forms).

   • Use: migraine prevention when palinopsia rides with migraine.

   • Side effects: fatigue, low HR/BP; avoid in asthma.

7. Amitriptyline / Nortriptyline (tricyclics).

   • Dose: 10–25 mg at night, titrate.

   • Use: migraine prevention, sleep, anxiety modulation.

   • Side effects: dry mouth, constipation, next-day grogginess.

8. Verapamil (calcium-channel blocker).

   • Dose: 120–240 mg/day (SR forms).

   • Use: certain migraine variants; clinician-directed.

9. Clonidine (alpha-2 agonist).

   • Dose: 0.05–0.1 mg at night, titrate.

   • Use: HPPD case reports; dampens adrenergic arousal.

   • Side effects: low BP, sedation. PMC

10. SSRIs/SNRIs for comorbid anxiety/depression

• Caution: some antidepressants (e.g., trazodone, nefazodone, mirtazapine) have reports of causing palinopsia. If needed, choose and monitor carefully with a specialist. Cleveland Clinic

Important caution: Topiramate, though a migraine drug, is a known cause of palinopsia in multiple reports. If you developed palinopsia on topiramate, discuss dose reduction/alternatives with your prescriber. PubMed

Dietary molecular supplements

1. Magnesium glycinate or citrate 200–400 mg nightly — supports migraine control and cortical stability.

2. Riboflavin (B2) 200–400 mg/day — migraine prevention support.

3. Coenzyme Q10 100–300 mg/day — cellular energy; migraine data.

4. Omega-3 fatty acids (EPA/DHA) 1–3 g/day — anti-inflammatory, neural membrane support.

5. Melatonin 2–5 mg at bedtime — sleep stabilization, migraine benefit.

6. Vitamin D3 per deficiency status — neuro-immune modulation; test first.

7. Vitamin B12 (e.g., 1,000 mcg/day oral) if low — supports nerve function.

8. L-theanine 100–200 mg once/twice daily — anxiolytic; may reduce symptom focus.

9. Curcumin 500–1,000 mg/day (with piperine) — anti-inflammatory; check anticoagulants.

10. Ginkgo biloba 120–240 mg/day (EGb 761) — microcirculatory/neuromodulatory effects; monitor for bleeding risks.

There is no evidence that immune-boosting drugs, “regenerative” medicines, or stem-cell therapies treat palinopsia. They are not recommended for this symptom and may carry risks or be unproven/expensive. The effective strategy is to find the trigger, treat the cause (e.g., migraine, seizure, medication effect), and use targeted neuromodulation (tints, CBT, select medicines). PubMed

Surgeries

1. Tumor resection (occipital/posterior lesion). Why: remove mass irritating visual cortex; may reduce palinopsia if the lesion caused it. PMC

2. AVM treatment (microsurgical resection or endovascular therapy). Why: cure AVM, prevent hemorrhage, reduce cortical irritation. PubMed

3. Aneurysm clipping/coiling (posterior circulation). Why: treat dangerous vascular cause impacting visual pathways.

4. Epilepsy surgery (focal occipital focus) in select, refractory cases. Why: eliminate seizure generator that produces palinopsia auras.

5. Decompression/hematoma evacuation after hemorrhage or severe trauma. Why: relieve mass effect on visual cortex.

Surgery is not a treatment for routine palinopsia. It is reserved for clear, surgically-treatable causes identified on imaging. ScienceDirect

Ways to prevent flares

1. Review new/worsening symptoms after any medication change; seek help early. Cleveland Clinic

2. Avoid hallucinogens and psychoactive recreational drugs. PMC

3. Manage migraine with lifestyle and, if needed, preventive meds.

4. Keep regular sleep and limit screen glare/flicker.

5. Use FL-41/tinted options if you’re light-sensitive. PMC

6. Hydrate and avoid long fasting (glucose swings).

7. Protect your head—seatbelts, helmets.

8. Treat anxiety; learn calming skills to reduce symptom amplification.

9. Moderate alcohol/caffeine (can trigger migraine/sleep loss).

10. Keep routine eye and neuro checkups if you have VSS/migraine/seizure history.

When to see a doctor—right away vs routine

Call emergency services now if palinopsia is sudden and comes with new severe headache, one-sided weakness/numbness, trouble speaking, double vision, or confusion (possible stroke or bleed).
Urgent appointment if palinopsia is new after a head injury, with seizures, or with rapid vision change.
Soon/routine if it persists for days, recurs, or started after a new medicine—bring your full medication/supplement list. Cleveland Clinic

---

What to eat and what to avoid

Eat more of:

1. Magnesium-rich foods (leafy greens, nuts, seeds, legumes).

2. Omega-3 sources (fatty fish, walnuts, flax/chia).

3. B-vitamin foods (eggs, dairy or fortified alternatives, greens).

4. Colorful vegetables & fruits (antioxidants for vascular health).

5. Hydrating fluids (water, herbal teas).

Eat less/avoid (especially if migraine-prone):

1. Highly processed foods high in additives/MSG for some people.
2. Large caffeine swings (either heavy use or abrupt withdrawal).
3. Alcohol, especially red wine and spirits if they trigger you.
4. Skipping meals—aim for steady glucose.
5. Very late-night heavy meals that disrupt sleep.

Frequently asked questions (FAQs)

1) Is palinopsia dangerous?
Often no, but sometimes it’s a sign of a serious brain problem. That’s why new, sudden, or changing symptoms deserve medical evaluation and, if needed, imaging. PubMed

2) Will it go away?
If a medicine caused it, symptoms often improve after stopping that drug (under supervision). In VSS/HPPD, symptoms may wax and wane; some improve with tints, CBT, or lamotrigine/benzodiazepines. PubMedPMC

3) Is this the same as normal afterimages?
No. Normal afterimages follow bright exposure and fade quickly; palinopsia is more frequent, can appear in ordinary lighting, and may be accompanied by trails/ghosting. Cleveland Clinic

4) Do glasses help?
Standard glasses fix blur; precision tints (e.g., FL-41) can lower afterimages, glare, and visual stress in many people. PMC

5) Can screen changes help?
Yes—higher refresh rate, lower brightness, dark modes, anti-glare, and regular breaks can reduce symptoms. Ophthalmology Times

6) Which medicines help most?
Evidence favors lamotrigine and benzodiazepines (e.g., clonazepam) in VSS/HPPD-type cases; seizure meds help if seizures are the cause. Responses vary. American Academy of NeurologyPMC

7) Which medicines can cause palinopsia?
Reports link trazodone, nefazodone, mirtazapine, topiramate, risperidone, clomiphene, and some hormonal contraceptives. Cleveland Clinic

8) Is topiramate safe if I already have palinopsia?
It has repeatedly been reported to trigger palinopsia; discuss alternatives with your clinician. PubMed

9) Can anxiety make it worse?
Yes. Anxiety increases attention to visual sensations; calming the mind often reduces symptom intensity.

10) Is palinopsia part of visual snow?
Often, yes. Many people with VSS report palinopsia, and both may share brain mechanisms. PMC

11) Are stem cells or “immune boosters” helpful?
No reliable evidence supports them for palinopsia; they’re not recommended. PubMed

12) Could this be a stroke?
Sudden palinopsia with other neuro symptoms can be stroke—treat as an emergency. SCIRP

13) What if my MRI is normal?
That’s common in illusory palinopsia (migraine/VSS/drug-related). Management focuses on triggers, tints, CBT, and selective meds. ScienceDirect

14) Can children get palinopsia?
It’s less studied, but the same principles apply: evaluate for causes, avoid triggers, and use conservative measures first.

15) Will wearing dark sunglasses indoors help?
Use moderate tint; very dark indoor lenses can worsen light sensitivity over time. Aim for tailored filters (e.g., FL-41) instead.
