Introduction to Unilateral Neglect Unilateral neglect, often simply termed neglect, is a profoundly debilitating neuropsychological syndrome characterized by an individual’s failure to report, respond, or orient to meaningful stimuli presented on the side of space opposite to a brain lesion, despite the sensory or motor capacity to do so. Unlike simple sensory loss, such as […]
Introduction to Perceptual Extinction Perceptual extinction, often referred to alternatively as sensory inattention, represents a complex neurological phenomenon observed following specific brain lesions, primarily affecting the mechanisms of attention and sensory awareness. It is characterized by a failure to perceive a stimulus when it is presented concurrently with an identical or similar stimulus in the […]
Introduction and Definition of Asomatognosia Asomatognosia is a highly specialized neurological syndrome characterized fundamentally by the profound inability of an individual to recognize or acknowledge the existence of one side or one specific part of their own body, typically an entire limb. This lack of awareness persists despite the fact that the primary sensory pathways […]
Definition and Core Characteristics Motor neglect, often referred to as motor hemi-inattention, represents a complex neuropsychological syndrome characterized by the failure to spontaneously initiate or execute movements with the limb contralateral to a hemispheric lesion, despite the preserved physical capacity to perform the movement. Fundamentally, this condition involves the neglect or profound misutilization of the […]
