Electroconvulsive therapy hasn't negative effects on short-term memory function, as assessed using a bedside hand-held device

Abstract

Electroconvulsive therapy (ECT) is effective in the treatment of treatment-resistant major depression. The fear of cognitive impairment after ECT often deters patients from choosing this treatment option. There is little reliable information regarding the effects of ECT on overall cognitive performance, while short-term memory deficits are well known but not easy to measure within clinical routines. In this pilot study, we examined ECT recipients' pre- and post-treatment performances on a digital ascending number tapping test. We found that cognitive performance measures exhibited good reproducibility in individual patients and that ECT did not significantly alter cognitive performance up to 2 hours after this therapy was applied. Our results can help patients and physicians make decisions regarding the administration of ECT. Digital measurements are recommended, especially when screening for the most common side effects on cognitive performance and short-term memory.

MMSE Changes During and After ECT in Late-Life Depression: A Prospective Study

“…The use of modern techniques, such as an iPadbased measurement approach or interactive voice response, could be future solutions in finding a balance between easy-to-use and sensitive tests for monitoring cognitive effects of ECT in the elderly. 50,51 In conclusion, our data offer no evidence for ECTrelated deleterious cognitive effects, as measured with the MMSE, during and up to 6 months after the index course of ECT in patients with LLD. In the event of baseline cognitive impairment, MMSE scores seem to improve significantly during ECT and 6 months after ending it.…”
