Conflict of intentions due to callosal disconnection.
OBJECTIVES Three patients with callosal syndrome manifested a peculiar symptom in that they were unable to perform intended whole body actions because another intention emerged in competition with the original one. Attempts were made to clarify the symptomatology of this manifestation and its possible mechanism is discussed. METHODS The three patients are described and previous reports on pat...
متن کاملAnton’s Syndrome following Callosal Disconnection
Anosognosia for cortical blindness, also called Anton's syndrome, is a rare neurological disorder usually following bilateral lesions to occipital cortices. Neuropsychological, morphological and functional neuroimaging (SPECT and fMRI) findings are reported in a patient who incurred Anton's syndrome after an ischaemic lesion confined to the left occipital lobe involving the corpus callosum.

متن کاملIs autism due to cerebral-cerebellum disconnection?
Autism has been linked to thalidomide exposure at 20-24 days gestation. At this stage, the embryo is roughly the size of this 'C', and has yet to develop its brain (except for brainstem cranial motor nerve nuclei). The neuropathology responsible for autism is presently unknown, but whatever it is, it must logically be one that can be induced by such an early occurring brainstem cranial motor ne...
متن کاملTransitory alexia without agraphia: a disconnection syndrome due to neurocysticercosis.
We describe a 65-year-old male who presented with acute onset inability to read, without any difficulty in writing. A clinical diagnosis of alexia without agraphia was made and the patient was subjected to routine investigations including contrast MRI. MRI showed a ring-enhancing lesion in left occipital area, suggestive of neurocysticercosis supported by quantitative enzyme-linked immunosorban...
متن کاملQuantitative proton MR spectroscopy findings in the corpus callosum of patients with schizophrenia suggest callosal disconnection.
BACKGROUND AND PURPOSE The callosal disconnectivity theory was previously proposed to explain the pathophysiology of schizophrenia. The goal of this study was to investigate the metabolic integrity of the corpus callosum in patients with schizophrenia by proton MR spectroscopy. MATERIALS AND METHODS Twelve first-episode and 16 chronic patients meeting the Diagnostic and Statistical Manual of ...
