Journal ArticleDOI

Mark A. Frye,Terence A. Ketter,Timothy A. Kimbrell,Timothy A. Kimbrell,Robert T. Dunn,Andrew M. Speer,Elizabeth A. Osuch,David A. Luckenbaugh,Gabriela Cora-Locatelli,Gabriele S. Leverich,Robert M. Post +10 more
TL;DR: This controlled investigation preliminarily suggests the efficacy of LTG in treatment-refractory affectively ill patients and further definition of responsive subtypes and the role of these medications in the treatment of mood disorders requires additional study.
Journal ArticleDOI
Frequency dependence of antidepressant response to left prefrontal repetitive transcranial magnetic stimulation (rTMS) as a function of baseline cerebral glucose metabolism
Timothy A. Kimbrell,John T. Little,Robert T. Dunn,Mark A. Frye,Benjamin D. Greenberg,Eric M Wassermann,Jennifer D. Repella,Aimee L Danielson,Mark W. Willis,Brenda E. Benson,Andrew M. Speer,Elizabeth A. Osuch,Mark S. George,Robert M. Post +13 more
TL;DR: Preliminary results suggest that antidepressant response to rTMS might vary as a function of stimulation frequency and may depend on pretreatment cerebral metabolism.
Journal ArticleDOI
Effects of mood and subtype on cerebral glucose metabolism in treatment-resistant bipolar disorder
Terence A. Ketter,Tim A. Kimbrell,Mark S. George,Robert T. Dunn,Andrew M. Speer,Brenda E. Benson,Mark W. Willis,Aimee L Danielson,Mark A. Frye,Peter Herscovitch,Robert M. Post +10 more
TL;DR: In bipolar depression, a pattern of prefrontal hypometabolism is observed, consistent with observations in primary unipolar and secondary depression, suggesting this is part of a common neural substrate for depression independent of etiology.
Journal ArticleDOI
Principal components of the Beck Depression Inventory and regional cerebral metabolism in unipolar and bipolar depression.
Robert T. Dunn,Robert T. Dunn,Tim A. Kimbrell,Tim A. Kimbrell,Terence A. Ketter,Terence A. Ketter,Mark A. Frye,Mark A. Frye,Mark W. Willis,David A. Luckenbaugh,Robert M. Post +10 more
TL;DR: Psychomotor-anhedonia symptoms in unipolar and bipolar depression appear to have common, largely right-sided neural substrates, and these may be fundamental to the depressive syndrome in bipolars.
Journal ArticleDOI
Clozapine in bipolar disorder: treatment implications for other atypical antipsychotics
Mark A. Frye,Terence A. Ketter,Lori L. Altshuler,Kirk D. Denicoff,Robert T. Dunn,Timothy A. Kimbrell,Gabriela Cora-Locatelli,Robert M. Post +7 more
TL;DR: In this article, the authors focus on the use of atypical antipsychotics in the treatment of bipolar disorder focusing on clozapine as the prototypical agent, and present a review focusing on their use in acute and long-term management of bipolar disorders.
