Some antidepressant drugs, especially tricyclic ones--(TCA), have cardiovascular side effects. To compare the effects of antidepressant drugs, the electrocardiogram (ECG), vectorcardiogram (VCG), and body surface maps (BSM) were recorded in psychiatric patients without cardiovascular diseases
Eight psychotropic drugs, mainly acting on the catecholaminergic systems, were investigated in an open field setting. All drugs but one showed a significant reduction in overall activity over time. Only piribedil at 32 mg/kg showed an increase, while 2 mg/kg showed a decrease over time. Amineptine
Clinical descriptions of depression date back to antiquity. Scientific investigations of mood disorders started only 150 years ago. An historical overview of depression leads into today's knowledge that depressive disorders are common, serious, and sometimes life-threatening and that their effects
Psychoactive pollutants, such as antidepressants, are increasingly detected in the environment. Mounting evidence suggests that such pollutants can disrupt the behaviour of non-target species. Despite this, few studies have considered how the response of exposed organisms might be mediated by social
The effects of repeated administration of a tricyclic antidepressant, imipramine, and a selective serotonin reuptake blocker, citalopram, for 14 days (10 mg/kg p.o., twice daily), were studied ex vivo in rat frontal cortex slices prepared 48 h after last dose of the drug. Treatment with both
Major depression is a severe psychiatric syndrome with very high prevalence and socio-economic impact. Its pathophysiology is poorly known, yet several neurotransmitter systems and brain areas have been implicated. Selective serotonin (5-hydroxytryptamine, 5-HT) reuptake inhibitors (SSRI) and
Major depression, affecting an estimated 350 million people worldwide, poses a serious social and economic threat to modern societies. There are currently two major problems calling for innovative research approaches, namely, the absence of biomarkers predicting antidepressant response and the lack
Antidepressants, particularly tricyclic (TCA) antidepressants, may have cardiotoxic effects, such as cardiac arrhythmias, especially in patients with cardiovascular diseases. For most of TCA, no exact correlation between dosage, plasma levels and changes of ECG parameters of standard ECG has been
BACKGROUND
Evidence suggests that a novel type of magnetic resonance imaging (MRI) scan called echo planar magnetic resonance spectroscopic imaging (EP-MRSI) has mood-elevating actions in humans during the depressive phases of bipolar disorder. We examined whether a low-energy component of EP-MRSI
The effect of the tricyclic antidepressants imipramine and desipramine were studied on field potentials in the rat hippocampal slice. The electrically evoked stratum radiatum nerve volley, excitatory postsynaptic potential (e.p.s.p.) and pyramidal cell layer population spike (PS) were recorded in
Recent longitudinal neuroimaging studies in patients with electroconvulsive therapy (ECT) suggest local effects of electric stimulation (lateralized) occur in tandem with global seizure activity (generalized). We used electric field (EF) modeling in 151 ECT treated patients with depression to
The human serotonin transporter (hSERT) regulates the spatial and temporal actions of serotonin (5-HT) neurotransmission by removing 5-HT from the synapse. Previous studies have identified residues in the third transmembrane helix (TMH) that may be important for substrate translocation or antagonist
