Bianchi's syndrome

Overview called aphasia - apraxia - alexia syndrome; Parietal lobe syndrome. Cause pathogenesis Where parietal and blood circulatory disturbance, oncology, and trauma can cause the levy. But in the middle cerebral artery branch Central cortex parietooccipital occlusions most common. If the middle cerebral artery extensive damage, there may be many other hemispheric hemiplegia symptoms, but not the performance parietal lobe syndrome. Clinical manifestations aphasia (sensory aphasia), apraxia and loss Reading (loss was accompanied by the loss Reading), in the contralateral side who feel, with the corresponding hand and foot sensitivity sexual agnosia, temporarily light hemiplegia. Damage to the parietal lobe (right benefit) performance for the left-size autologous partial understanding not, can not understand space, dressing apraxia. apraxia structure, space alexia, the loss calculation. Performance of the left parietal lobe damage to the structure apraxia, perceived sexual apraxia and agraphia, such as lost time. Differential diagnosis (1) cerebral infarction (cerebral 362002) adjacent to the main hemisphere parietal infarction pm The syndrome emerged in the middle cerebral arterial occlusion parietooccipital support the most common. The disease was mostly seen in 60 years of age or older, particularly associated with arteriosclerosis and hypertension patients; more quiet break disease, the symptoms often hours or longer period of time gradually increased, showed progress-stroke type; maintain a clear sense, but aphasia hemiplegia symptoms was not significant. CSF clear, the pressure is not high. (2) glioma (glioma) in the performance of the syndrome often before history of chronic headaches, was gradually increasing sexual, With the increased tumor mass, nausea, vomiting, palilledema increased intracranial pressure and other symptoms. Early course is not easy to identify with cerebral infarction. CT findings of the main side of the hemisphere parietal lobe lesions, enhanced annular, or nodular porphyritic strengthened. Main side of the hemisphere parietal other lesions, such as meningioma, and metastatic tumor, brain abscess can arise, such as the syndrome. (3) Gerstmann's syndrome is the main side of the hemisphere temporal lobe lesions caused angular gyrus, easily confused with the syndrome. This levy not including the fingers awareness, awareness about not lost, stolen wrote four symptoms, also have various degrees of mental symptoms, aphasia, not understanding color, sexual orientation visual loss, lost time, lost use of such structures. This levy a total of four symptoms were rare.
