[2025-10-01T21:58:48.681083] [PI reasoning] **Evaluating ECT complications**

I need to find out the most common complication of electroconvulsive therapy (ECT). Common side effects include memory disturbances, especially retrograde and anterograde amnesia. Headache and muscle ache are typical side effects, but retrograde amnesia is often highlighted as a complication in exams. I want to confirm this by searching for information on "most common complication of ECT retrograde amnesia" to ensure I'm providing the right answer.

[2025-10-01T21:58:57.574147] [PI reasoning] **Clarifying amnesia types**

Most resources indicate that retrograde amnesia is common with ECT, but I need to focus on it being the most common complication. I should also think about immediate side effects like headaches and confusion. Typically, exam answers lean towards "retrograde amnesia" or memory impairment.

As for my options, I see differences between antegrade and retrograde amnesia. ECT can cause both, but retrograde seems to be the more often cited. I’ll look for more info on the frequency of anterograde amnesia related to ECT.
