Clinical and neuroimaging features in 6 patients with corticobasal syndrome / 中华内科杂志

ABSTRACT

The clinical and imaging data in 6 patients with corticobasal syndrome were retrospectively analyzed. Six patients presented asymmetric clinical symptoms, including 5 with cognitive impairment, 6 with emotional disorders, 2 with cortical sensory deficit, 5 with lalopathy, and 4 with apraxia. All patients developed limb dystonia and limb or trunk stiffness, 4 with tumble, 4 with bradykinesia, and 2 with tremor. Brain magnetic resonance imaging (MRI) showed that 4 patients had unilateral cerebral atrophy and 2 had mild atrophy of bilateral hippocampus. Localized low glucose metabolism in the unilateral cerebral lobe was seen in four patients by positron emission computed tomography (PET) examination, suggesting that PET is helpful for the diagnosis of corticobasal syndrome.
