Simple observation is able to identify the most severe forms. Patients may turn their head and eyes for the neglect syndrome. Many early studies hypothe sized that neglect was simply the result of a loss of sen sation or perception (Battersby, Bender, Pollack, & Kahn, 1956; Denny-Brown, Meyer, & Horenstein, 1952; MeFie, Pierey, & Zangwill, 1950). Subsequent theorists have proposed that neglect is due either to an imbalanee 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 (Heilman, Watson, & Valenstein, 1985).

It is considered that the patients could execute leftward movements as the task oriented their attention sufficiently to the left. Neglect syndrome is a neurophysiologic condition characterized by a malfunction in one hemisphere of the brain, resulting in contralateral hemispatial neglect in the absence of sensory loss and the right parietal lobe lesion being the most common anatomical site leading to it.

Neglect syndrome is due to lesions in the

Patients with neglect fail to orient to events (visual, auditory, tactile stimuli) occurring on the side of space contralateral to the side of the lesion (i.e., the left-hand side in right-brain-damaged patients) and to explore it. Gerstmann syndrome is a rare disorder characterized by the loss of four specific neurological functions: Inability to write (dysgraphia or agraphia), the loss of the ability to do mathematics (acalculia), the inability to identify one’s own or another’s fingers (finger agnosia), and inability to make the distinction between the right and left side of the body. Pusher syndrome is a condition observed in some people following a stroke which has left them with one side weakened due to hemiparesis.Sufferers exhibit a tendency to actively push away from the unweakened side, thus leading to a loss of postural balance.It can be a … Belfer RA, Kiein BL, On- L Use ofthe skeletal survey in the evaluation of child maltreatment./4m y fmerg/Med 2001;19:122-4. 4 Day F, Clegg S, McPhiilips M, Mok ).

Neglect has been described also in animals (monkey, cat, rat) with, however, no hemispheric asymmetries. Patients with neglect fail to orient to events (visual, auditory, tactile stimuli) occurring on the side of space contralateral to the side of the lesion (i.e., the left-hand side in right-brain-damaged patients) and to explore it. Gerstmann syndrome is a rare disorder characterized by the loss of four specific neurological functions: Inability to write (dysgraphia or agraphia), the loss of the ability to do mathematics (acalculia), the inability to identify one’s own or another’s fingers (finger agnosia), and inability to make the distinction between the right and left side of the body.
