Summary
Anton-Babinski syndrome (ABS) is a rare condition causing denial of vision loss and confabulation after bilateral occipital lobe injury. Early stroke diagnosis is vital for effective rehabilitation and improved patient outcomes.
Area of Science:
- Neuropsychiatry
- Neurology
- Ophthalmology
Background:
- Anton-Babinski syndrome (ABS) is a rare neuropsychiatric disorder.
- Characterized by visual anosognosia and confabulation despite intact visual pathways.
- Typically caused by bilateral occipital lobe damage from cerebrovascular accidents.
Observation:
- This report details a case of suspected ABS in a woman in Malaysia.
- The patient experienced a recurrent ischemic stroke.
- The stroke led to bilateral occipital lobe injuries.
Findings:
- The patient presented with symptoms consistent with Anton-Babinski syndrome.
- Diagnosis was challenging due to the rarity of the condition and stroke recurrence.
- Confirmation of stroke as the cause was critical.
Implications:
- Accurate diagnosis of stroke is essential for managing ABS.
- Tailoring rehabilitation strategies based on stroke diagnosis improves functional outcomes.
- This case highlights the importance of recognizing ABS in stroke survivors.

01:21Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:15Ischemic Stroke ll: Pathophysiology
An ischemic stroke occurs when a cerebral blood vessel becomes obstructed, most often by a thrombus or embolus, interrupting the delivery of oxygen and glucose to brain tissue. Because neurons rely on continuous aerobic metabolism, energy failure begins within minutes of reduced perfusion. The region receiving the least blood flow becomes the infarct core, an area of irreversible cellular death. Surrounding this core lies the penumbra, a zone of hypoperfused but still viable tissue that is...
01:26Transient Ischemic Attack l: Introduction
A transient ischemic attack (TIA) is a brief episode of neurological dysfunction caused by a temporary, focal reduction in cerebral blood flow. Although symptoms resemble those of an ischemic stroke, the interruption in perfusion is short-lived and does not cause permanent infarction. TIAs are clinically important because they often serve as early warning events for future stroke.Mechanisms of Transient Cerebral IschemiaTransient cerebral ischemia may arise through several mechanisms. One...
