Assessing structural integrity of the pyramidal tracts with diffusion spectrum imaging to predict postoperative motor function in pediatric epilepsy patients with hemispherectomy [PDF]

Acta Epileptologica, 2023
Background Hemispherectomy is an effective treatment option for patients with drug-resistant epilepsy caused by hemispheric lesions. However, patients often have deterioration of their motor functions postoperatively. Diffusion spectrum imaging (DSI) was

Dynamic Diffusion Tensor Imaging Reveals Structural Changes in the Bilateral Pyramidal Tracts After Brain Stem Hemorrhage in Rats [PDF]

Frontiers in Neuroanatomy, 2016
Background and Purpose: Few studies have concentrated on pyramidal tract (PY) changes after brain stem hemorrhage (BSH). In this study, we used a diffusion tensor imaging (DTI) technique and histologic identification to investigate longitudinal PY ...

Clinical and magnetic resonance imaging features in acute ischemic stroke with early wallerian degeneration: a case-control study [PDF]

BMC Neurology
Background In advanced stages, Wallerian degeneration (WD) after cerebral infarction appears as an abnormality in the descending corticospinal tract on T2-weighted images. However, early WD in this region is detectable via diffusion-weighted imaging (DWI)

Ten-Year Follow-Up of Transcranial Magnetic Stimulation Study in a Patient With Congenital Mirror Movements: A Case Report [PDF]

Annals of Rehabilitation Medicine, 2019
Most studies concerning congenital mirror movements (CMMs) have been focused on the motor organization in the distal hand muscles exclusively. To the best of our knowledge, there is no data on motor organization pattern of lower extremities, and a ...

Predictors and Outcomes of Salvaging the Corticospinal Tract After Thrombectomy in Basilar Artery Occlusion Stroke

Frontiers in Neurology, 2022
BackgroundRegional eloquence of brainstem structures may contribute to neurological status in basilar artery occlusion (BAO) stroke. The corticospinal tract (CST) which is vulnerable to BAO is important for motor activity.

Occasional essay: upper motor neuron syndrome in amyotrophic lateral sclerosis [PDF]

, 2020
The diagnosis of amyotrophic lateral sclerosis (ALS) requires recognition of both lower (LMN) and upper motor neuron (UMN) dysfunction.1 However, classical UMN signs are frequently difficult to identify in ALS.2 LMN involvement is sensitively detected ...
