Optic Apraxia: Definition, History, and Further Readings
Abstract
Optic apraxia is a disorder of the central nervous system that affects the ability to visually interpret and identify objects. It is characterized by difficulty in retrieving the visual image of an object from memory, even though the patient is still able to recognize the object upon direct visual inspection. This paper provides a review of the definition, history, and further readings of optic apraxia.
Introduction
Optic apraxia is a disorder of the central nervous system characterized by difficulty in retrieving the visual image of an object from memory, even though the patient is still able to recognize the object upon direct visual inspection. It is typically associated with brain damage in the occipital and parietal lobes. The disorder is usually encountered in patients with severe brain damage, primarily resulting from stroke or traumatic brain injury.
Definition
Optic apraxia is defined as the inability to remember the visual image of an object despite being able to recognize the object upon direct visual inspection. It is a disorder of the central nervous system that affects the ability to visually interpret and identify objects. Therefore, patients with optic apraxia are unable to identify objects by visual inspection alone, but are still able to recognize the object when it is presented to them in physical form.
History
Optic apraxia was first reported in 1891 by German neurologist Carl Wernicke. He described the disorder as “visual memory apraxia” and documented several case studies. Since then, the disorder has been studied extensively and is currently considered a well-established neurological condition.
