Somatosensory dys- function is a common problem following stroke. In partic- ular, somatosensory impairments, such as impairment in touch, proprioception, light touch, and vibration have been frequently observed (Carey et al., 1993; Sullivan and Hed- man, 2008; Tyson et al., 2008). Patients with somatosensory dysfunction show negative effects on motor control, and it sometimes becomes difficult to perform daily activities independently.展开更多

Disease progression and therapy during a 3-year period were followed up at different time points: before and after reoperation, after radiation therapy, and 1 year after irradiation. During the whole 3-year follow-up period, the patient exhibited no neurological deficits while functional magnetic resonance imaging revealed different topologies of the language-related brain network. During disease progression and after irradiation, the language-related brain network was extended or completely transferred to the nondominant (right) hemisphere. In addition, after reoperation and 1 year after irradiation, language areas were primarily found in the language dominant (left) hemisphere. Our results suggest a high level of adaptability of the language-related cortical network of the bilateral hemispheres in this low-grade glioma patient.展开更多
