Anton syndrome

From WikiMD's Wellnesspedia

Anton syndrome, also known as Anton's blindness or Anton-Babinski syndrome, is a rare cortical visual disorder characterized by the denial of visual loss (anosognosia) despite obvious evidence of blindness. It was first described by the Austrian neurologist Gabriel Anton in 1899, and later given its name by the French neurologist Joseph Babinski in 1914.

Overview[edit | edit source]

Patients with Anton syndrome are cortically blind but affirm, often quite adamantly, that they are capable of seeing. This condition is a form of anosognosia, a denial of illness, and is most commonly associated with extensive bilateral occipital lobe damage. Despite their blindness, patients with Anton syndrome may attempt to walk around, bumping into objects and even injuring themselves due to their denied impairment.

Causes[edit | edit source]

Anton syndrome is typically caused by stroke, particularly bilateral occipital lobe stroke, but can also be caused by traumatic brain injury, brain tumor, or encephalitis. The exact mechanism of Anton syndrome is not well understood, but it is thought to involve damage to the visual cortex and visual pathways, leading to a disconnection between the visual and language centers of the brain.

Symptoms[edit | edit source]

The primary symptom of Anton syndrome is the denial of blindness. Patients may also exhibit confabulation, creating elaborate, often implausible, explanations for their inability to see. Other symptoms can include hallucinations, cognitive impairment, and spatial disorientation.

Diagnosis[edit | edit source]

Diagnosis of Anton syndrome is primarily clinical, based on the patient's symptoms and neurological examination. Neuroimaging techniques such as MRI and CT scan can be used to confirm the presence of damage to the occipital lobes.

Treatment[edit | edit source]

There is currently no cure for Anton syndrome. Treatment is supportive and focuses on managing symptoms and improving the patient's quality of life. This may involve occupational therapy, physical therapy, and cognitive behavioral therapy.
