Akinetopsia, often called “motion blindness,” is a rare neurological disorder in which a person cannot perceive motion in their visual field. Instead of seeing continuous movement, individuals with akinetopsia experience a series of still “snapshots,” making actions like pouring tea or watching traffic appear frozen and disjointed. This condition arises from damage to areas of the brain responsible for processing motion, most notably the middle temporal (MT/V5) visual cortex. Because motion perception is crucial for everyday activities—crossing streets safely, interacting in sports, even simple social cues—akinetopsia can severely impact quality of life.
Akinetopsia, also known as motion blindness, is an exceedingly rare neuropsychological disorder in which a person loses the ability to perceive motion in their visual field, despite intact perception of stationary objects. The term derives from the Greek words “a” (absence), “kinesis” (movement), and “opsis” (seeing), literally meaning “no perception of movement.” Under normal circumstances, specialized neurons in visual area V5 (also called MT) integrate successive snapshots of the world to create a fluid sense of motion. When V5 is damaged—due to stroke, trauma, neurodegenerative disease, or, experimentally, transcranial magnetic stimulation—patients describe the world as a series of static frames, like a stopped‐motion film or a strobe light effect WikipediaEyeWiki.
Under normal vision, our eyes detect changes in position and movement, sending information to specialized regions in the brain. The MT/V5 area integrates these signals, allowing us to see smooth, fluid motion. In akinetopsia, this integration fails. Patients report that moving objects seem to jump from one place to another, as if they’re viewing a flipbook missing frames. They may describe water in a glass as static until it abruptly changes level, or a person walking as if teleporting between positions. The experience can be frightening and disorienting, often leading to anxiety around any situation involving movement.
Types of Akinetopsia
Akinetopsia manifests in several forms, depending on the location and extent of brain damage:
Bilateral Akinetopsia
Damage occurs in both hemispheres’ MT/V5 regions, leading to a complete inability to perceive motion across the entire visual field.Unilateral Akinetopsia
Only one hemisphere is affected, resulting in motion blindness only in the opposite (contralateral) half of the visual field.Transient Akinetopsia
Short-lived episodes of motion blindness caused by fleeting disruptions, such as migraine aura or brief ischemic events.Developmental Akinetopsia
Extremely rare cases where individuals fail to develop normal motion perception, possibly due to congenital anomalies in motion-processing areas.Pharmacological Akinetopsia
Drug-induced motion blindness seen transiently with certain medications or toxins that disrupt cortical function.
Causes of Akinetopsia
Each of the following can damage motion-processing pathways, leading to akinetopsia:
Stroke in the MT/V5 Region
A blood clot or hemorrhage in the temporal lobe can destroy neurons that interpret movement, causing sudden-onset akinetopsia.Traumatic Brain Injury (TBI)
A severe head injury—such as from a fall or vehicle accident—can shear connections in visual motion areas, leading to persistent motion perception deficits.Surgical Resection
Removal of brain tumors near the MT/V5 cortex during neurosurgery may inadvertently damage motion-processing tissue.Brain Tumors
Primary or metastatic tumors pressing on or infiltrating the MT/V5 area can gradually impair motion detection, sometimes without affecting other aspects of vision.Multiple Sclerosis (MS)
Demyelinating lesions in the white-matter tracts connecting visual areas can disrupt motion signals, producing episodes of akinetopsia.Transient Ischemic Attacks (TIAs)
Brief interruptions of blood flow to motion cortex can cause temporary “snapshot” vision, resolving once perfusion returns.Encephalitis
Viral or autoimmune inflammation of the brain may target regions responsible for motion perception, leading to acute or subacute akinetopsia.Migraine Aura
In some sufferers, the cortical spreading depression underlying migraine can transiently suppress MT/V5 activity, causing short-lived motion blindness.Neurotoxicity
Exposure to certain toxins—such as carbon monoxide or heavy metals—can selectively impair cortical neurons involved in motion processing.Posterior Cortical Atrophy
A variant of neurodegenerative disease, often related to Alzheimer’s, which selectively wears down visual association areas, including those for motion.Cortical Dysplasia
Developmental malformations of the brain’s cortex may include abnormal MT/V5 structure, leading to congenital or early-onset akinetopsia.Radiation Necrosis
Brain radiation therapy for tumors may cause delayed injury to surrounding healthy motion-processing regions.Epileptic Seizures
Focal seizures originating in the temporal cortex can temporarily disrupt motion pathways, producing episodic motion blindness.Vascular Malformations
Arteriovenous malformations or cavernous hemangiomas near MT/V5 can bleed or compress tissue, impairing motion detection.Autoimmune Disorders
Conditions like anti-NMDA receptor encephalitis can target cortical neurons, sometimes affecting visual-motion areas among others.
Symptoms of Akinetopsia
Though the hallmark is inability to perceive motion, patients often report additional experiences:
“Frame-by-Frame” Vision
Objects appear in a series of still images rather than continuous movement.Difficulty Pouring Liquids
Water seems static until suddenly jumping to a new level, making pouring awkward or impossible.Trouble Crossing Streets
Inability to judge speed of oncoming cars can make street-crossing dangerous.Impaired Social Perception
Reading body language or lip movements is challenging, leading to social misunderstandings.Visual Disorientation
Rapid head turns can induce dizziness or confusion when motion cues are lost.Increased Anxiety
Fear of moving environments—crowded trains, busy streets—due to unpredictable “jumps” in vision.Reading Difficulties
Scanning lines of text may feel as if the lines suddenly shift or skip.Motion Sickness
A mismatch between vestibular signals and static visual input can provoke nausea.Poor Balance
Reliance on motion perception for posture adjustments is compromised, increasing fall risk.Fragmented Action Perception
Watching sports or vehicles feels jerky and unreal, reducing enjoyment of dynamic scenes.
Diagnostic Tests for Akinetopsia
To confirm akinetopsia and rule out other conditions, clinicians employ a range of evaluations across five domains.
Physical Examination
Visual Acuity Testing
Ensures basic eyesight is intact; normal acuity suggests the problem lies in motion processing rather than sharpness of vision.Pupillary Reflex Assessment
Checks neurological integrity of afferent/efferent pathways; normal reflexes support cortical rather than ocular cause.Extraocular Movements
Evaluates eye muscle function to exclude ophthalmological disorders that might mimic motion issues.
Manual (Clinical) Tests
Clinical Motion Perception Tasks
The patient watches a wand moved at various speeds and reports movement. Akinetopsia patients see only stationary positions.Optokinetic Nystagmus Test
A striped drum is rotated around the patient; inability to smoothly track stripes indicates motion-processing deficits.
Lab and Pathological Tests
Routine Bloodwork
Including complete blood count and metabolic panel to identify systemic conditions (e.g., infection, toxicity) that might affect the brain.Autoimmune Panel
Checks for antibodies (e.g., anti-NMDA) that cause encephalitis affecting visual cortex function.Toxicology Screen
Identifies exposure to neurotoxins like heavy metals or carbon monoxide that impair cortical neurons.
Electrodiagnostic Tests
Electroencephalography (EEG)
Records electrical activity to detect seizures or cortical irritability in motion-processing areas.Visual Evoked Potentials (VEP)
Measures brain responses to moving visual stimuli; reduced or delayed signals in MT/V5 suggest akinetopsia.
Imaging Tests
Magnetic Resonance Imaging (MRI)
High-resolution images reveal structural damage—strokes, tumors, demyelination—in the MT/V5 cortex.Functional MRI (fMRI)
Shows brain activation patterns when viewing moving versus stationary stimuli; lack of activation in MT/V5 confirms motion-processing deficit.Computed Tomography (CT) Scan
Useful in acute settings to detect hemorrhage or large lesions affecting visual motion areas.Positron Emission Tomography (PET)
Maps metabolic activity; hypometabolism in MT/V5 regions correlates with impaired motion perception.Diffusion Tensor Imaging (DTI)
Visualizes white-matter tracts; disruptions in connections between visual areas and motion-processing cortex can be identified.Magnetic Resonance Angiography (MRA)
Examines blood vessels supplying the temporal lobes, finding strokes or malformations that may cause akinetopsia.Single-Photon Emission Computed Tomography (SPECT)
Assesses regional cerebral blood flow; reduced perfusion in MT/V5 suggests localized dysfunction.Electroretinography (ERG)
Ensures the retina itself responds normally to light, ruling out retinal motion-detection problems.Eye Tracking Studies
Quantitative analysis of ocular pursuit movements demonstrates inability to follow moving targets smoothly.Neuropsychological Testing
Comprehensive battery including motion-coherence tasks, separating motion detection from other visual or cognitive deficits.
