No. However, memory loss is a well-recognized side effect. In the majority of people, memory loss is temporary and is limited to the time period when they received ECT. In some cases, memory loss goes further back, and some of this, but not necessarily all, may come back once the course of ECT is finished. Memory-related side effects are affected by the specific parameters of an individual's treatment, including the number of treatments administered and the electrode placement. Unilateral ECT, with both electrodes placed on the same side of the head, causes less memory loss, but is also less effective, than bilateral (bitemporal or bifrontal) electrode placements. It's also important to keep in mind that depression itself can cause memory impairment, especially when people are most unwell, and therefore most likely to be getting ECT.
