  • Title: Remote cortical dysfunction as a possible cause of subcortical neglect? A regional cerebral blood flow study.
    Author: Hublet C, Demeurisse G, Paternot J, Colson C, Capon A.
    Journal: Eur Neurol; 1995; 35(5):254-8. PubMed ID: 8542912.
    Abstract:
    Cortical remote effects of right deep-seated lesions were studied with two cerebral blood flow measurement methods (two-dimensional xenon-133 inhalation and 99mTc HMPAO SPECT) in a population of 13 right-handed stroke patients. A neuropsychological battery of tests suitable for assessment of possible visual neglect was performed. Neglect was present in 7 cases. A regional cortical hypoperfusion was observed in all patients. However, in neglect patients it was more extended and involved the right inferior parietal region suggesting a causal relationship between cortical dysfunction and neuropsychological deficit. This finding supports the model attributing neglect to a unilateral attention-arousal defect in a cortico-limbic-reticular loop.
