To evaluate the time periods of Wallerian degeneration (WD) in which the diffusion parameters of ipsilateral corticalspinal tract (CST) can be used to predict the motor function outcome after brain infarction. ⋯ The rFA and ipsilateral FA values after 2 weeks of stroke onset correlate with the motor function outcome.

Our institution serves a population of 160,000 and performed 14.4 endovascular cerebral aneurysm interventions annually, averaged over a 5-year period. The purpose of this study was to examine the safety and efficacy of endovascular treatment of cerebral aneurysms at a lowvolume center. ⋯ Endovascular coil embolization at a small volume nonspecialized community center is feasible with satisfactory procedural risk and clinical outcomes.

The acquisition of literacy during childhood may affect the functional organization of the brain. We studied the effects of illiteracy on neuropsychological tests and brain glucose metabolism in later life. ⋯ These results suggest that reading and writing during childhood is associated with activation of the frontal pole that may play a critical role in complex aspects of human cognition.

Though routine neuroimaging is usually normal in essential tremor (ET) there is clinical evidence of widespread involvement of central nervous system. This study aimed at determining morphological changes in brain of patients with ET using voxel-based morphometry (VBM) analysis and also compare the subtypes of ET. ⋯ Patients with ET showed widespread areas of atrophy in both cerebellum and cerebral GM, which supports the current concept of the progressive and diffuse nature of ET. Patients with additional head tremor may represent a distinct subgroup of ET.
