Journal ArticleDOI
Hyponatraemia during psychopharmacological treatment: results of a drug surveillance programme.
Martin Letmaier,Annamaria Painold,Anna K. Holl,Hartmut Vergin,Rolf R. Engel,Anastasios Konstantinidis,Siegfried Kasper,Renate Grohmann +7 more
TL;DR: Plasma sodium levels below 130 mmol/l (severe HN according to AMSP) were reported in 93 patients during this period and Combinations of several drugs known to induce HN significantly increased the risk of HN, e.g. more than 10-fold for SSRI+diuretics+ACE inhibitors.
Journal ArticleDOI
No association of clock gene T3111C polymorphism and affective disorders.
Ursula F. Bailer,G. Wiesegger,Friedrich Leisch,Karoline Fuchs,I. Leitner,Martin Letmaier,Anastasios Konstantinidis,J. Stastny,Werner Sieghart,Kurt Hornik,B. Mitterauer,Siegfried Kasper,H.N. Aschauer +12 more
TL;DR: Results suggest that there is no association between the T3111C SNP and affective disorders in general.
Journal ArticleDOI
Comparative EEG mapping studies in Huntington’s disease patients and controls
Annamaria Painold,Peter Anderer,Anna K. Holl,Martin Letmaier,Gerda M. Saletu-Zyhlarz,Bernd Saletu,Raphael M. Bonelli +6 more
TL;DR: The slowing of the EEG in HD reflects a disturbed brain function in the sense of a vigilance decrement, electrophysiologically characterized by inhibited cortical areas and a lack of normal routine and excitatory activity, similar to those found in other dementing disorders.
Journal ArticleDOI
EEG low-resolution brain electromagnetic tomography (LORETA) in Huntington's disease.
Annamaria Painold,Peter Anderer,Anna K. Holl,Martin Letmaier,Gerda M. Saletu-Zyhlarz,Bernd Saletu,Raphael M. Bonelli +6 more
TL;DR: Correlation analyses revealed that a decrease of alpha and theta power correlated significantly with increasing cognitive and motor decline, and LORETA proved to be a sensitive instrument for detecting progressive electrophysiological changes in HD.
Journal ArticleDOI
Venous thromboembolism during treatment with antipsychotics: Results of a drug surveillance programme.
Martin Letmaier,Renate Grohmann,Christiana Kren,Sermin Toto,Stefan Bleich,Rolf R. Engel,Thomas Gary,Konstantinos Papageorgiou,Anastasios Konstantinidis,Anna K. Holl,Annamaria Painold,Siegfried Kasper +11 more
TL;DR: Clinicians should consider AP drug exposure as a potential risk factor for VTE for patients older than 65 years of age with mood disorders, as the diagnosis of an affective disorder seems to increase the risk of VTE.
