Due to their clinical and genetic heterogeneity, these diseases are ... -
Clinical characteristics of patients with spinocerebellar ataxias 1, 2, 3 and 6 in the US; a prospective observational study
Ashizawa, Tetsuo; Figueroa, Karla P; Perlman, Susan L; Gomez, Christopher M; Wilmot, George R; Schmahmann, Jeremy D; Ying, Sarah H; Zesiewicz, Theresa A; Paulson, Henry L; Shakkottai, Vikram G; Bushara, Khalaf O; Kuo, Sheng-Han; Geschwind, Michael D; Xia, Guangbin; Mazzoni, Pietro; Krischer, Jeffrey P; Cuthbertson, David; Holbert, Amy Roberts; Ferguson, John H; Pulst, Stefan M; Subramony, SH (BioMed Central, 2013)Background: All spinocerebellar ataxias (SCAs) are rare diseases. SCA1, 2, 3 and 6 are the four most common SCAs, all caused by expanded polyglutamine-coding CAG repeats. Their pathomechanisms are becoming increasingly ... -
Consensus Paper: The Role of the Cerebellum in Perceptual Processes
Baumann, Oliver; Borra, Ronald J.; Bower, James M.; Cullen, Kathleen E.; Habas, Christophe; Ivry, Richard B.; Leggio, Maria; Mattingley, Jason B.; Molinari, Marco; Moulton, Eric A.; Paulin, Michael G.; Pavlova, Marina A.; Schmahmann, Jeremy D.; Sokolov, Arseny A. (Springer US, 2014)Various lines of evidence accumulated over the past 30 years indicate that the cerebellum, long recognized as essential for motor control, also has considerable influence on perceptual processes. In this paper, we bring ... -
Delayed Posthypoxic Leukoencephalopathy: Improvement with Antioxidant Therapy
King, Franklin; Morris, Nicholas A.; Schmahmann, Jeremy D. (S. Karger AG, 2015)Introduction: Delayed posthypoxic leukoencephalopathy (DPHL) may result from a variety of hypoxic insults, including respiratory depression from an opiate overdose. The underlying pathophysiological mechanism of DPHL remains ... -
Diffusion Spectrum Imaging Shows the Structural Basis of Functional Cerebellar Circuits in the Human Cerebellum In Vivo
Granziera, Cristina; Schmahmann, Jeremy Dan; Hadjikhani, Nouchine; Meyer, Heiko; Meuli, Reto; Wedeen, Van Jay; Krueger, Gunnar (Public Library of Science, 2009)Background: The cerebellum is a complex structure that can be affected by several congenital and acquired diseases leading to alteration of its function and neuronal circuits. Identifying the structural bases of cerebellar ... -
Enhancing the Temporal Complexity of Distributed Brain Networks with Patterned Cerebellar Stimulation
Farzan, Faranak; Pascual-Leone, Alvaro; Schmahmann, Jeremy D.; Halko, Mark (Nature Publishing Group, 2016)Growing evidence suggests that sensory, motor, cognitive and affective processes map onto specific, distributed neural networks. Cerebellar subregions are part of these networks, but how the cerebellum is involved in this ... -
