Journal ArticleDOI
Effects of clozapine on positive and negative symptoms in outpatients with schizophrenia.
Alan Breier,Robert W. Buchanan,Brian Kirkpatrick,Orlando R. Davis,Donna Irish,Ann Summerfelt,William T. Carpenter +6 more
TL;DR: Clozapine has superior efficacy for treating positive symptoms in partially responsive outpatients with chronic schizophrenia, suggesting that it has utility for a broad spectrum of patients with schizophrenia beyond the most severely ill.
Journal ArticleDOI
Review of Clinical Correlates of P50 Sensory Gating Abnormalities in Patients with Schizophrenia
TL;DR: Despite the prominent role that P50 abnormalities have played in the understanding of schizophrenia, there is a relative dearth of data examining P50 clinical correlates, and multiple studies have failed to document a cross-sectional or longitudinal relationship between P50 and positive, negative, or other symptoms.
Journal ArticleDOI
Gamma and Delta Neural Oscillations and Association with Clinical Symptoms under Subanesthetic Ketamine
L. Elliot Hong,Ann Summerfelt,Robert W. Buchanan,Patricio O'Donnell,Gunvant K. Thaker,Martin A. Weiler,Adrienne C. Lahti,Adrienne C. Lahti +7 more
TL;DR: In this article, the effects of ketamine, an N-methyl-D-aspartate antagonist that can mimic some clinical aspects of schizophrenia, on auditory-evoked neural oscillations using a paired-click paradigm were investigated.
Journal ArticleDOI
Evoked gamma band synchronization and the liability for schizophrenia.
L. Elliot Hong,Ann Summerfelt,Robert P. McMahon,Helene Adami,Grace Francis,Amie Elliott,Robert W. Buchanan,Gunvant K. Thaker +7 more
TL;DR: Gamma band synchronization was found to be reduced in first-degree relatives with schizophrenia spectrum personality symptoms, and patients on new generation antipsychotic medications may exhibit enhanced gamma band synchronization.
Journal ArticleDOI
Continuous versus targeted medication in schizophrenic outpatients: outcome results.
William T. Carpenter,Thomas E. Hanlon,Heinrichs Dw,Ann Summerfelt,Brian Kirkpatrick,Jerome Levine,Robert W. Buchanan +6 more
TL;DR: In this article, the authors report on the outcome of treatment of 116 outpatients with chronic schizophrenia who were assigned to a 2-year, single-blind course of treatment with either targeted or continuous medication.
