Brief Summary
In this clinical trial, postictal phenomena (i.e., headache, delirium) will be investigated after administration of acetaminophen and nimodipine in depressed patients receiving electroconvulsive therapy (ECT). Postictal phenomena are thought to result from decreased cerebral blood flow and decreased oxygen concentration in the brain. It is expected that acetaminophen and nimodipine will reduce these postictal phenomena, compared to no treatment, because they target these mechanisms.

Secondary Outcomes (5)
Postictal reorientation time (by Sobin, 1995)
immediately after each ECT session, up to 12 times per patient (across 6 weeks)

baseline, in the first hour after 3 electroconvulsive therapy sessions, after approx. 3 months, after approx. 6 months, lasts approx. 5 min.
Arterial Spin Labeling MRI

- Time Frame
- Data will be archived for 15 years (according to the standard practice of Rijnstate Hospital). Data will become available as of the last date of testing (approx. December 2020).
- Access Criteria
- Data will be shared with experienced data analysts at the Amsterdam UMC (MRI analyses).
The EEG, MRI, and psychometric data will be shared with the University of Twente and the Amsterdam UMC. All patient data will be anonymized so that it cannot be connected to the patients. Demographic data will also be included in these files and anonymized.
