Agnosia Optical

Agnosia of optical perception (optical ataxia, or gaze agnosia, English optaesthesia, visuapraxia, optiasythymia) is a violation of the ability of the visual system to arrange images in three-dimensional space, leading to loss of the ability to identify objects as a result of visual impairment. A characteristic symptom of optical agnosia is the loss of the ability to read, write and recognize.

It occurs after damage to the occipital region of the brain or its connections with the frontal regions. Immediately after this, patients generally lose the ability to somehow navigate the world around them. Subsequently, they begin to develop a number of symptoms. Clinically, the disease manifests itself in extremely varied ways. It can be established that either the object (object finger) or color (color finger) form of perception suffers (in 40% of patients), the sense of distance (30%), the nature of the lines (20%), the sense of the length of movement (8%).
