I'm a little hesitant to talk about my negative response to ECT, as I know it can be a life-saver for some.
But this was my experience:
Had 1 bilateral treatment in hospital - Instantaneous response!! But wained after 6 wks.
Had approx. 20 more unilateral outpatient treatments - Sadly, zero response, plus much short-term memory loss AND lost a chunk of my long-term memory (which is something they say won't happen, but it did -- however, this was also back around the late '90s, so I'm sure there have been improvements/more safeguards since then.
You will absolutely need someone to accompany you home from treatments.
Despite my experience, I'd probably still give it a try, as I know many who did really well with it. It's usually a last line of treatment, so your doctors must feel it's warranted.
Best of luck, whatever your decision!
Fibromyalgia, CFS, possible MCS, Chronic Depression/Anxiety Disorder, Agoraphobia, PTSD ... But they're all connected & I'm working on them all - I will prevail!
