Abstract

The unilateral neglect syndrome is defined as a lack of directed attention to one half of the space or the body. It has been reported mainly after cortical lesions of the right parietal or frontal lobe in man. However, there is strong experimental and clinical evidence for the existence of neglect syndromes of subcortical origin. The unilateral neglect syndrome is not the result of elementary sensory deficits. The failure in directed attention is dependent on an imbalance of hemispheric activation.

Sommario

La sindrome di in attenzione è definita come una mancanza di attenzione diretta, su una metà dello spazio o sull'emicorpo. È stata descritta soprattutto in relazioni a lesioni corticali situate a destra, in sede parietale o frontale nell'uomo. Tuttavia vi sono molti elementi sperimentali e clinici sull'esistenza di sindrome di inattenzione di origine sottocorticale. Infatti questa sindrome non è conseguenza di deficit sensoriali elementari, ma dipende da uno squilibrio di attivazione emisferica.
