Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
Clinical studies in severely depressed patients have shown that antidepressants and ECT can increase Brain Derived Neurotrophic Factor (BDNF) serum levels. BDNF serum levels will be measured before, during and after ECT. In animal studies this increase in serum BDNF was shown to induce hippocampal mossy fiber sprouting and the investigators want to study this phenomenon in humans. Recently, a volumetric magnetic resonance imaging study showed increased hippocampal volume in patients with depression. Hippocampal volumes will be determined with magnetic resonance imaging scannings including voxel based morphometry. Severe depression is accompanied by a dysfunction of the hypothalamus pituitary adrenal (HPA) axis. Cortisol and several other hormones have psychotropic effects, and their excesses or deficiencies induce states of mania or depression. High levels of cortisol suppress hippocampal neurogenesis. Animal models have shown that this suppressive effect of cortisol on hippocampal neurogenesis could be reversed to normal levels by electroconvulsive stimulation, the animal model for ECT. This animal study is in good accordance with clinical findings.
The investigators hypothesize the following: Increase of brain-derived neurotrophic factor serum levels induced by electroconvulsive therapy are associated with remission and is correlated with a neurorestorative effect, which is an increase of hippocampal volume. Non- response to ECT is explained by either low BDNF serum levels regardless of hippocampus size, or by (more advanced) medial temporal lobe atrophy (beyond a point of no return) despite increased BDNF serum levels.
Additionally, four relevant functional candidate genes will be examined, based on their putative role in neurotrophic processes and/or in treatment response in depression: the brain derived neurotrophic factor gene, the serotonin transporter gene, the vascular endothelial growth factor gene and the apolipoprotein gene.
The investigators will also evaluate cognitive and psychomotor changes following electroconvulsive therapy given their clinical relevance in late life depression.

electroconvulsive therapy
only one arm in this study: patients who are treated with electroconvulsive therapy and have been given anesthesia with etomidate and succinylcholine
ECT
ECT was administered twice a week with a constant-current brief-pulse device (Thymatron, System IV). Motor and electroencephalographic seizures were monitored to ensure adequate duration and quality. Subjects were all treated with right unilateral (RUL) ECT with stimulus intensity 6 times the initial seizure threshold (ST), as determined by empirical dose titration at the first treatment, until remission (Montgomery-Åsberg Depression Rating Scale (MADRS) (27) \< 10 in two consecutive ratings with a week interval). Subjects who failed to respond right unilateral ECT after the sixth treatment were switched to bitemporal ECT (1.5x seizure threshold).
Etomidate
Anesthesia was achieved with intravenous administration of etomidate (0.2mg/kg).
Succinylcholine
Anesthesia was achieved with intravenous administration of succinylcholine (1mg/kg).
