Journal ArticleDOI
Quantification of metabolic differences in the frontal brain of depressive patients and controls obtained by 1H-MRS at 3 Tesla.
Stephan Gruber,Richard Frey,Vladimir Mlynarik,Andreas Stadlbauer,Angela Heiden,Siegfried Kasper,Graham J. Kemp,Ewald Moser +7 more
TL;DR: It is demonstrated that absolute quantification of metabolite concentration is essential in properly identifying pathologic differences of brain metabolites in depression.
Journal ArticleDOI
Lack of analgesia by oral standardized cannabis extract on acute inflammatory pain and hyperalgesia in volunteers.
Birgit Kraft,Nathalie Frickey,R. M. Kaufmann,Marcus Reif,Richard Frey,Burkhard Gustorff,Hans G. Kress +6 more
TL;DR: The results suggest that cannabinoids are not effective analgesics for the treatment of acute nociceptive pain in humans and point to the development of a hyperalgesic state under cannabinoids.
Journal ArticleDOI
Nonorganic insomnia in generalized anxiety disorder. 1. Controlled studies on sleep, awakening and daytime vigilance utilizing polysomnography and EEG mapping.
Gerda M. Saletu-Zyhlarz,Bernd Saletu,Peter Anderer,N. Brandstätter,Richard Frey,Georg Gruber,Gerhard Klösch,Magdalene Mandl,Josef Grünberger,Leopold Linzmayer +9 more
TL;DR: It is suggested that CNS hypervigilance and hyperarousal, as actual symptoms of GAD, lead to nocturnal insomnia, which in turn may cause-as a consequence of sleep pressure not slept off-diurnal tiredness.
Journal ArticleDOI
Global decrease of serotonin-1A receptor binding after electroconvulsive therapy in major depression measured by PET.
Rupert Lanzenberger,Pia Baldinger,Andreas Hahn,Johanna Ungersboeck,Markus Mitterhauser,Dietmar Winkler,Z Micskei,P. Stein,Georgios Karanikas,Wolfgang Wadsak,Siegfried Kasper,Richard Frey +11 more
TL;DR: A global involvement of the postsynaptic 5-HT1A receptor binding in the effect of ECT is proposed, with strongest reductions found in regions consistently reported to be altered in major depression and involved in emotion regulation.
Journal ArticleDOI
Myo-inositol in depressive and healthy subjects determined by frontal 1H-magnetic resonance spectroscopy at 1.5 tesla
Richard Frey,D. Metzler,P. Fischer,Angela Heiden,J. Scharfetter,Ewald Moser,Siegfried Kasper +6 more
TL;DR: This investigation is a pilot study which suggests an influence of age and antidepressants on mI levels and should be taken into consideration in further investigations in depressive patients.
