Major Depression Clinical Trial
Official title:
Randomized Controlled Comparison of Bifrontal and Right Unilateral ECT as to Effects on Depression, Global Cognitive Function and Biomarkers.
ECT (electroconvulsive therapy) is mostly given to patients between the age of 60 - 85 years. There is limited evidence on the efficacy and cognitive side-effects of right unilateral (RU) and bifrontal (BF) electrode positions, the placements that are considered safe for the elderly. As far as the investigators know no randomized controlled trials (RCTs) have yet been published describing this population treated with BF or RU ECT. Non-demented depressed patients will be randomized to either method (n = 2x36). Symptom intensity, global cognitive function and biomarkers will be related to 20 healthy comparators. Testing, evaluation of depression and blood-tests are done before ECT-treatment, after a series of 6-16 ECT and 3 months after terminated ECT-treatment.
Patients are assessed with Mini Mental Status Examination. Postictal reorientation time is
measured. There is also a weekly rating of depression depth during the series. After the 6th
ECT; Mini Mental Status Examination For a subgroup of patients; extensive blood-test samples
are taken on the day of the 6th ECT.
Some of the patients receive continuation-ECT once monthly after the series. In these months
patients receive treatment as usual (naturalistic observation).
