The neglect syndrome (or more simply, neglect) is a fascinating and multifaceted neurological disorder. Patients with neglect act as if portions of their world do not exist. In addition to spatial neglect, they may appear unconcerned about their hemi-paresis and even deny ownership of a limb on the neglected side of their body. A widely cited operational definition states that persons with neglect fail to report, respond, or orient to external stimulation (or mental representations of sensory events) located contralateral to a brain lesion (i.e., contralesional) when the failure cannot be attributed to a primary sensory or motor deficit such as hemianopia or paralysis.
