Paroxysmal exercise-induced dyskinesia and epilepsy is due to mutations in SLC2A1, encoding the glucose transporter GLUT1
Paroxysmal exercise-induced dyskinesia (PED) can occur in isolation or in association with epilepsy, but the genetic causes and pathophysiological mechanisms are still poorly understood. We performedExpand

Assessment of Neuroinflammation and Microglial Activation in Alzheimer’s Disease with Radiolabelled PK11195 and Single Photon Emission Computed Tomography
Objectives: Inflammation contributes to degeneration in Alzheimer’s disease (AD), not simply as a secondary phenomenon, but primarily as a significant source of pathology. [123I]iodo-PK11195 is aExpand
